Hi there Joelthanks for the tip anywaybearings replaced on the crankshaft; standard sizes as requested by the workshop who took measurements & found the crankshatf to be within specs.the camshaft is worn out (must have been running without oïl in the past).will keep on nursing the engine so as I can spare until 2020, then open it up again & control condition before taking decision on continuing or replacing with new.

Christian Alby,
 First thanks for letting me know that your buzzer apparently comes on at 1 bar, that is something that I was wondering about and could not find the data online.      Ok, so your oil pressure at 1500 RPM is 3.2 bar.  The Perkins specifications are saying the the oil pressure at full throttle RPM should be between 2.1 and 4.2 bar so since I assume that cruise RPM is 1500 or higher your engine would be operating well within the allowed design specifications currently.  I personally would not be overly concerned with the oil pressure being a bit low at idle since the engine is not loaded at that time.   If the oil pressure remains stable and does not drop much over time, I would think that it should be ok for a while.  Normally however a new or a newly built engine should hit the highest pressure shown in the specifications  (which in your case would be 4.2 bar) which would be the setting for the pressure relief valve in the oil pump.  When this is happening, it tells you that the pump is supplying more oil than the engine can use at the max oil pressure so the balance of the oil is returned to the oil pan via the relief valve.  The excess amount of oil being pumped is a really good thing because as the engine wears and the clearances open up, the proper oil pressure can be maintained for a much longer period.  Since your engine is not reaching the higher pressure, it means that as any wear occurs  the pressures will drop rather than remaining stable which will likely lead to shorter useable engine life.   In your previous email, you stated that the bearings had been replaced but you did not say which ones..  Were the Camshaft, connecting rod and main bearings all replaced?  The rocker arm and bearings might have been ok but were these checked to be sure?   Was the crankshaft and camshaft measured and verified to be within allowable tolerances?   Hopefully all of the journals were smoothed up to remove any sharp edges.  If all of this work was done and done correctly then you should have a tight engine and the scored oil pump might well be the culprit.  If some of the bearings were not replaced or there was excess wear in any of the parts creating out of spec clearances, that might be the cause of the lower than expected oil pressure rather than the oil pump.  If this were my engine and I knew that the engine had been properly rebuilt other than the scored oil pump I would certainly be inclined to change or at least see about rebuilding the original pump at a good machine shop if no replacement parts were found.   Did you look on Ebay for replacement oil pump parts?  I have seen recent listings for pumps that are supposed to be for the 4-154 but have not verified if those parts would fit our engines.
   Just one more thing.  If it were me, I would continue to be on the look out for any evidence of diesel getting back into the oil..  While you feel sure that the lift pump was the cause of your problem,  it is possible that the injection pump could be leaking some as well.  Once your engine is broken in, you might be able to up the idle oil pressure a bit with the engine warm by switching to a synthetic oil which does not thin out as much when hot.  Correcting the cause of the low oil pressure would certainly be the best solution but I also understand the need to use our boats.   
Best of luck,

Hi there James

 

Starting oïl pressure (cold engine) reads now 3 bars with 1300 rpm (goes up soon as engine starts - no time lag, good sign that pump is working)

goes down to 2..8 bars when warming up to 70°C

 

idling at 700 rpm when warm at 70°C drops down to 1 bar - sets on the warning beeper

changed setting on engine to run idling at 850 rpm - oïl pressure goes up to 1.2 bars (no more warning beeper - a rest for our ears)

 

when accelerating to 1500 rpm oïl pressure runs up to 3.2 - again immediate, no time lag)

 

oïl pressure gauge is reading; was on zero when first started & cooling hoses were inverted. Went up to reading when corrected.. No clue on correctness of reading as no calibration done.

 

However did the good old check on oïl pressure to unscrew the oïl filter & got a good shower, followed by unscreing the pressure gauge & watching the closest I know to a Blow-out on an oïl rig.

 

I did not find a replacement oïl pump for the engine & fitted the 'old scored' one back in; still looking & searching now with oïl pumps manufacturers as I have seen similar designs, but different sizes on the net. Intent is to find one to be available by early 2020 latest to allow for dismantling of engine (again) & refitting a new or reconditionend pump.

 

Guess I will try & stretch the life of my 4..154 to get some retunr on Investment for the repairs done here in Tenerife..

Christian Alby,

 

   Thanks for the initial update on your rebuilt Perkins.  The Perkins 4-154 manual that I just checked is showing the normal oil pressure to be between 30-60 PSI or about 2.1- 4.2 bar at “maximum engine speed”.  They do not seem to list an idling oil pressure.   What was the initial oil pressure when the engine was first started and cold?  How is the oil pressure at your normal cruising RPM?  Is there any chance that your oil pressure gauge is not reading correctly?   I am really happy that the engine seems to be running so well for you.   Were you unable to find a replacement oil pump for your engine?

will do an update when returning to home port in 2019

Just to complete results of trial run, oïl pressure went down to 1 bar at 700 rpm after 3 hrs running (cooling maintained at 70°C).

Engine purring nicely, no leaks.

I book it to the ol pump condition (scored  innards).

Added Wynn's Supercharge to thicken oïl & oïl pressure went up to 1.2 bar at 700 Rpm; much better but temporary solution.

Thinking of adding one oïl pump piggy-back on engine (oïl cooling hoses) either driven by pulley or electric. Will pursue.

Re: [Amel Yacht Owners] Re-rigging and mast step

Willem Kroes
 

Hi Tom,

 

On my SM2k, I bought early spring, there is also a staysail rigging installed. Mr. Olivier Beaute criticized the engineering when he surveyed the boat and this was redone properly this summer.

 

But I am confused about the correct sheeting of the staysail. Where to attach the sheeting blocks on deck? I have seen the arrangement on a 54, but the stays of that boat are totally different positioned

 

Did you have already some experience with this? May be some pictures?

 

Kind regards,

Onderwerp: RE: [Amel Yacht Owners] Re-rigging and mast step

 

 

I can second the comments here regarding Caribe Greement (the Amel rigger in Martinique). Philipe (owner) and Gaetan were great. We replaced all the standing rigging and added a staysail per Amel's specs including the backstay rigging. The work was done very professionally......and the total was about $10,000 for the rigging and another $6,000 for the staysail rig installation. We bought the actual staysail from North Sails in Martinique for around $2,000. Philipe and Gaetan seem to do quite a bit of work on Amels and they both love these boats (they also stock everything you would need)......Philipe told me he never sees an Amel come in with an actual rig failure as the components are of super high quality out of the factory. He's 53 and still climbs masts every day, so I guess he'd know.

Hey Eric- I've been toying around with the idea of repurposing the life-raft locker in this way.. One non-scientific data point that has given me pause is that when I last changed batteries, I had all 13 DT-31 batteries on the port side of my boat outside the cockpit waiting to be taken off. I noticed (or at least I perceived) a slight list of my boat to port. I wondered if 300 liters of fuel in the locker would create a similar issue. Have you noticed this ?

Re: [Amel Yacht Owners] Re: Auxiliary fuel tanks

In the deeper, somewhat less reliable, parts of my memory, I recall having read on this forum several years ago that the SM was originally designed without a generator. However, as actual production neared, the decision was made to install a generator, which had to be placed on the port side of the boat, hence the roughly 1 degree list. Every SM I have been on has had that “feature”.

Tom,

300 liters of diesel would weigh about 640 lbs, Thirteen G31 batteries at about 75 lbs per would weigh between 900 and 1000 lbs.

Just another data point for you as you decide what to do...

I get the distinct impression I am a minority on this, but I personally would skip this project--unless you motor a lot. A Super Maramu has a range with the installed tanks of about 1000 miles.  Much more twice than my previous boat and I never felt the need for more fuel in that one.  I don't think I have ever motor-sailed our Amel, but others seem to do this quite a bit. We c ruise full time, and buy fuel about four times a year.  For us, cutting out one fuel stop every 12 months just doesn't come close to justifying the project.

The liferaft locker does double duty on our boat, holding the raft and other things. I would need to make space in other places for them, and it's not worth it to me.  Also, we have the older boat with only 9 batteries, so we start out with a list to port from the weight of the generator on that side. I consider that list important, but maybe that's because I would rather sail in 4 or 5 knots of wind than listen to the motor...

The liferaft locker does double duty on our boat, holding the raft and other things. I would need to make space in other places for them, and it's not worth it to me.  Also, we have the older boat with only 9 batteries, so we start out with a list to port from the weight of the generator on that side. I consider that list important, but maybe that's because I would rather sail in 4 or 5 knots of wind than listen to the motor...

Hey Eric- I've been toying around with the idea of repurposing the life-raft locker in this way. One non-scientific data point that has given me pause is that when I last changed batteries, I had all 13 DT-31 batteries on the port side of my boat outside the cockpit waiting to be taken off. I noticed (or at least I perceived) a slight list of my boat to port. I wondered if 300 liters of fuel in the locker would create a similar issue. Have you noticed this ? Confession- I've done no calculations relating to the relative weights, the position of those weights, etc............one of those possible boat projects that sits idling in front of the first speed bump it encounters.

More than likely your problem is the crankshaft bearings and the connecting rod bearings clearances are too large. As the engine warms the expansion of components causes the clearances to increase even more and hence the oil pressure to go down.

 

The prognosis for this situation is not good. Sorry to be the bearer of bad news…

Hi there James

 

Starting oïl pressure (cold engine) reads now 3 bars with 1300 rpm (goes up soon as engine starts - no time lag, good sign that pump is working)

goes down to 2.8 bars when warming up to 70°C

 

idling at 700 rpm when warm at 70°C drops down to 1 bar - sets on the warning beeper

changed setting on engine to run idling at 850 rpm - oïl pressure goes up to 1.2 bars (no more warning beeper - a rest for our ears)

 

when accelerating to 1500 rpm oïl pressure runs up to 3.2 - again immediate, no time lag)

 

oïl pressure gauge is reading; was on zero when first started & cooling hoses were inverted. Went up to reading when corrected. No clue on correctness of reading as no calibration done.

 

However did the good old check on oïl pressure to unscrew the oïl filter & got a good shower, followed by unscreing the pressure gauge & watching the closest I know to a Blow-out on an oïl rig.

 

I did not find a replacement oïl pump for the engine & fitted the 'old scored' one back in; still looking & searching now with oïl pumps manufacturers as I have seen similar designs, but different sizes on the net. Intent is to find one to be available by early 2020 latest to allow for dismantling of engine (again) & refitting a new or reconditionend pump.

 

Guess I will try & stretch the life of my 4.154 to get some retunr on Investment for the repairs done here in Tenerife.

Just to complete results of trial run, oïl pressure went down to 1 bar at 700 rpm after 3 hrs running (cooling maintained at 70°C).

Engine purring nicely, no leaks.

I book it to the ol pump condition (scored  innards).

Added Wynn's Supercharge to thicken oïl & oïl pressure went up to 1.2 bar at 700 Rpm; much better but temporary solution.

Thinking of adding one oïl pump piggy-back on engine (oïl cooling hoses) either driven by pulley or electric. Will pursue.

Tom,

300 liters of diesel would weigh about 640 lbs, Thirteen G31 batteries at about 75 lbs per would weigh between 900 and 1000 lbs.

Just another data point for you as you decide what to do...

I get the distinct impression I am a minority on this, but I personally would skip this project--unless you motor a lot. A Super Maramu has a range with the installed tanks of about 1000 miles.  Much more twice than my previous boat and I never felt the need for more fuel in that one.  I don't think I have ever motor-sailed our Amel, but others seem to do this quite a bit.

Miles,

   If you have not yet done so, check to be sure that the drag is all of the way off on the wheel.  I think that I read a while back that the steering cables are sealed but get someone to verify this.  The rudder,  hull and skeg clearances are tight so a bit of growth could also certainly stiffen things up.

I had wondered about that welded ring. My boat has been re engined but I guess this is to stop running the engine and prop shaft alternator together! Smart.

Re: [Amel Yacht Owners] Re: Hurth Transmissions freewheeling folding prop

Correct. Leave engine in neutral. Your keys should be on a welded ring. Take keys from ignition and switch on prop alternator key. Green light should show charging. To stop turn off and extract key. Green light may still show charging. Stop by putting gears into reverse. Into neutral and start engine.
Don’t know what size your alternator is. Mine is a 50amp. It only puts a couple of amps in until I’m over 5 knots then it starts producing. Crossed the Atlantic with batteries at 100% all the way - all on the prop alternator.
Have fun.

Hello
I have yet to test out my maramu prop shaft alternator. I’m hoping to this week though. 
Am I right in assuming I put the gear into neutral to allow the prop to freewheel then switch on the alternator charging ?
Simple as that?
To stop just engage the gear to stop the prop from turning then turn off the alternator?
Many thanks in advance

   I am glad that you are having good luck!  Thanks for the tip on the
Militec-1, what I have read about the product sounds very promising.  I
will order some and give it a try.




 




   So if I understand you correctly,  you changed your aluminum cooler
back in 1997 when the engine had 4,000 hours on it,  you now have 10,000
hours on your engine and you are still using the same cooler?  May I ask
where you ordered your cooler from?  It seems that some people are having
problems with their coolers corroding quickly.




 




   Perhaps our boats were built side by side side since Sueno is #220?  
May I ask where your boat is now?

97 . when I received the boat, with 4,000 hours.




From 99 to 2006 I was living on board using marinas only when could not be

Gabriele Anolini,




 




   That is amazing,  you must be taking exceptional care of your
transmission.  Do you have a cooler on your transmission?  Foley seems to
be saying that 1000 hours is about all that we should expect.  It would be
nice to know which factors seem to lead to a longer service life.   




 




Happy Holidays,




 




James

Re: [Amel Yacht Owners] Re: Perkins M 4.154 repairs

Christian Alby,

   Thanks for the initial update on your rebuilt Perkins.  The Perkins 4-154 manual that I just checked is showing the normal oil pressure to be between 30-60 PSI or about 2.1- 4.2 bar at “maximum engine speed”.  They do not seem to list an idling oil pressure.   What was the initial oil pressure when the engine was first started and cold?  How is the oil pressure at your normal cruising RPM?  Is there any chance that your oil pressure gauge is not reading correctly?   I am really happy that the engine seems to be running so well for you.   Were you unable to find a replacement oil pump for your engine?  

Best,

James

will do an update when returning to home port in 2019
Just to complete results of trial run, oïl pressure went down to 1 bar at 700 rpm after 3 hrs running (cooling maintained at 70°C).
Engine purring nicely, no leaks.
I book it to the ol pump condition (scored  innards).
Added Wynn's Supercharge to thicken oïl & oïl pressure went up to 1.2 bar at 700 Rpm; much better but temporary solution.
Thinking of adding one oïl pump piggy-back on engine (oïl cooling hoses) either driven by pulley or electric. Will pursue.

christian alby,


    Thanks for taking the time to update us on your freshly rebuilt 4-154 along with verifying the cause of the failure.  I hope that the engine provides you many years of good service.  If not too much trouble, could you do another update in 1-2 years on how the engine has held up?

Thanks,

James

Thanks to all Amel sailors who assisted me find parts for my 1982 Perkins M 4.154.
Engine is rebuilt now with new pistons, liners, bearings ... Including a brand new starter to replace the one burnt by the workshop electrician who tried to run faster by hooking my 'old faithfull' 12 volts starter on 2 batteries in series at 24 Volts !
Engine on board 19/12; hooked up & running same day at 17:00 (lost time on drive end bolts offset by 1/4 turn - lift engine & rotate whell -, then oïl cooler hoses inverted, no return = no oïl on pressure gauge).

the cause of the fault was definetly the diesel lift pump diaphragm; 63 US$ Worth of spare, Worth changing on engines which did not run for over a year or so. Check them often.

Otherwise I can only recommend UK & USA suppliers who responded & supplied replacement parts; And Tenerife workshop 'Precision T.' who did a perfect job on the mechanical part; Just keep electricians away from our installations, not their best show of experience.

We shall sail away on 24/12 to continue our round trip of South Atlantic.

fair winds to all
