Re: Prop is spinning freely

Danny and Yvonne SIMMS
 

Hi Bill,

Volvo recommend either freewheeling or in gear. However care needs to be taken that either forward or reverse gear is selected depending on which firmly stops the spinning, the wrong one will allow slow revolution of the shaft from partially closed clutches which of course will cause wear. How to know which? When sailing observe the shaft rotating, put it into gear, the correct one will produce a satisfying clunk and the shaft will stop, the wrong one will slow the shaft but not fully stop it.

Chris,

There is usually not a simple answer to your question. 

 The most common issues for non-braking are mechanical within the caliper mechanism. Non-braking is usually caused by the following in order of probability:
  • The caliper bushings will wear and cause misalignment and open calipers
  • The brake shoe pads will wear
  • The caliper frame may be loose on the hydraulic cylinder
  • The hydraulic cylinder spring may need adjustment
  • The hydraulic cylinder may need an overhaul
  • The caliper mechanical springs may be broken or defective
  • Or, something else I haven't thought of 
The most common issue for not releasing is hydraulic in nature.

The quarter that Courtney refers to will usually solve the problem when the bushing is worn, or the brake pad is worn.

It is possible that the Italian-made Caliper you have is no longer made. If so, Amel will supply you with a new model that will work, but not necessarily fit without minor modification.

I believe that you can either leave the prop free spinning or place the transmission in gear to stop the spinning, however, I do not recommend either of those because I have not been able to verify the long-term issues, if any, in doing either.

Re: Prop is spinning freely

 

For your information, I have seen all sorts of "fixes" for worn-out caliper bushings when performing Pre-Purchase consulting. This photo takes the Grand Prize Award of all I have seen. It includes a wooden clothespin and wire, both circled in red. The new owner of this SM replaced the calipers with a slightly different model caliper from the same Italian manufacturer as the original. Amel SAV provided the new caliper:

Re: SM 2000 Mizzen Spreader Deck Light

Hi Jeff,

I hope it helps but you'll see on this page the reference used by Amel on your boat which is Aquasignal.

It's nos available with an (expensive) LED bulb which you'll see on this page.

https://www.svb24.com/en/aqua-signal-kiel-led-floodlight-white.html

My two cents is that, after some years the small teeths which hold the buld wouls be fragile (as well on your main mast light = same brand, same bulb, different model) and it would be a great idea to change it for a brand new.

Lift you up, use a drill to remove "rivets" and install the new.

Kind regards

Hi Gary,
I was referring to the cockpit area light mounted on the forward aspect of the mizzen mast.  

The old bulb housing was very rusted along with the internal mount for the bulb.  I've ordered a new bulb but am not 100% sure how to mount it inside the housing.
It is a 50W PAR36 bulb, not LED.

Jeff, Are you referring to the cockpit area light mounted on the forward aspect of the mizzen mast, or are there actually spreader lights on the mizzen mast spreaders?

Where the plunger comes out of the cylinder to push against the brakes.  You tape a quarter to the spot on the brakes where the plunger contacts it this will increase the compression of the pads

Re: Prop is spinning freely

Alan Leslie
 

Chris,

There is a spring inside the brake caliper piston cylinder that is supposed to push the piston and keep the pads pressed against the brake disc when the engine is not running. The caliper is semi floating like a car disc brake
There is an adjustment bolt on the aft end of the the cylinder that allows you to increase the pressure on the spring. Adjusting this, may or may not help.
If the pads are badly worn, it won't help, you need new pads.
I had this issue when in the Pacific a few years ago and I solved it by adding an adjustment bolt on the forward caliper so I could make the brake just close.
It's quite a simple system really.

Re: "Apple is examining a chemistry for the car battery called LFP, or lithium iron phosphate, for its car", that will bring the cost down for all of us

Edited

This will not likely have a trickle down effect for marine batteries anytime soon.  The key differentiator for Apple is the "monocell" cell design, not the LFP chemistry.  It's their way of trying to make up for the lower energy density of the LFP chemistry compared to other Lithium Ion chemistries like the NCA chemistry (lithium-nickel-cobalt-aluminum) that Tesla mainly uses.  Tesla batteries are made from older, proven cylindrical cell design as well as a different NCA chemistry.  Scott, your Victron batteries actually use prismatic LFP cells, not cylindrical cells:  https://shop.pkys.com/Ever-wondered-what-is-inside-a-Victron-Lithium-Battery_b_167.html 

Most other drop-in batteries like Battleborn do use cylindrical LFP cells to make their batteries.

Re: Placement of Beta 60 in an Amel Maramu #replacement

Thank You Danny,

Thank you for the explanation.

 

I am headed off to St Maarten for a new Yanmar  mid January.

 

It is working perfectly and all the fluid samples are great. However with over 7,000 hours, I thought I would just replace it and never have to worry about something going bang on a passage .

I was concerned about the possibility of breaking the oil pump, a wrist pin, or a connecting rod.

Hi Eric, it wasn't an hours issue. What caused its demise was the misunderstanding about rpm. It was maxing at 2800 rpm under load and the consensus on the forum was that there must be something wrong since under no load it would easily do 4000. Many of us tried to resolve what wasn't an issue. So when after about 2 years and 25000 sailing miles suddenly it would rev up to  3500 under load I thought it had resolved whatever was wrong. HOWEVER 2800rpm was the correct max under load and the ability to rev higher was caused by a jammed wastegate on the turbo. This is intended to open progressively to reduce the boost as revs increase.  So with it jammed closed the boost pressure was excessive, hence the higher revs achieved. Not that I ran it at high revs a lot, but over several years the excess pressure damaged the rings and pistons and eventually I couldn't get better than 2200 rpm under load. I tried everything without success including quite a lot of Volvo specialist time. So one day, having had the engineer on board yet again I said b....it and ordered a new one. In retrospect it would have made more sense to do a recondition on the TMD22 since I had replaced most of the bolt ons.

So you TMD owners. 2800 load rpm is correct and if you are getting more, check the waste gate.

Happy New Year to you all

Hi. The Beta spunds a good option. However I repkced my tmd22 with  volvo d275 and with 1300 hpurs up it is going well. Plus points. It has significantly more torque. Even with the propellor barnacle encrusted it pulls its standard 3000 rpm. Existing gearbox bolted on. Enging mount hole  positioning was identical, fitted perfectly onto the egine bearers. All we had to do was make new forward end spacers to align the engine. Could not have been easier.

It is significantly lighter than the tmd22 and this shows in the fore aft trim. It is a turbo. But no timing belt. It is a push rod engine, not ohc. I did not make up the spacer alignment tool for this job, nor for the engine mout repacement this year. No difficulties at all. Nil vibration.

The Beta 60 has more torque than the tmd22. The hp is measured at the gearbox output 
I would say that the Beta 60 has the same power as the tmd22 but lower in the rev range. My cruising revs is around 1800 and 6kn  flat out 2200 and 7.5 kn in flat calm water. 30kn wind on the nose would be 4kn 

The cubic capacity makes a difference.  It is nice to have no  turbo  and no timing belt.

Hello Larry on Sulawesi,

 

Is the Beta 60 sufficient for an SM?  A

Curious as I would like a non TC engine when I have to replace my Volvo TDM22.

 

Kind regards,

Hi Dirk,

Sula (SM 140) also has a Beta 60 fitted by the previous owner. She has the standard 70 amp 12v insulated return alternator and the 24v 60amp insulated return secondary alternator. No adjustments were made to oil and fuel filters.
