Leece -Neville Alternator external regulator install

Dan Carlson
 

Doe anyone have a photo or two from installing an external regulator on their Leece-Neville 175amp alternator?  I have the wiring diagrams from a previous post but was wondering if someone had an actual photo of the wire that needs to be snipped? And any additional tips or caveats? 

I will be installing the WakeSpeed WS500 regulator. The wiring to the alternator for the WS500 looks very similar to the Balmar 624.

Thanks and regards, Daniel Carlson on SM#387, sv BeBe

Re: Prop Shaft Squeak

ngtnewington Newington
 

Hi James,

Since you plan to pull the shaft and check it at a machine shop you should also check that the prop is true. Many years ago (1991) I had a similar problem, it was on my first boat a 35’ gaff cutter. In Venezuela I installed a new engine, but the whole drive train was never checked. By the time I arrived in New Zealand I had only put on 200 hours as there was obviously a problem. Anchored off Russel in the Bay of Islands I pulled the prop and shaft, bunging the hole from inside and out. The machine shop right there checked the shaft, and it was bent. He checked the prop and it was true but completely the wrong prop for the type of boat. At very reasonable cost he supplied me with a second hand shaft and a second hand prop. I then went to town on the alignment and got it spot on. From that moment on engaging gear was a silky smooth transition and gradually powering up and loading the engine was a joy.

The point being that the whole power train from engine to prop is critical. I suggest in addition to checking the shaft, you have the prop checked for balance.

As James on Sueno says, the cutlass bearing might need “bedding in”. It should not be tight. It should be only bearing on the bottom due to the weight of the shaft with a very slight gap above and around. So there is a tiny bit of wiggle and you should be able to turn it by hand easily.

The alignment:

I see the shaft alternator and coupling arrangement from your photos. I suggest that initially you slide on the temporary nylon bearing down the shaft so that it sits in the stern tube and the shaft is then supported for and aft with minimal wiggle. Then gently slide the shaft forward so that it kisses the coupling. If it slides perfectly into the coupling slot without pushing it up or down or to one side then the alignment is already pretty good. 
I would then using feeler gauges check the alignment on the coupling to the transmission whilst rotating it. I am not sure that you actually need to remove the alternator pulley. If you want to, then the shaft should reach with the prop removed. 

I have said that the alignment is critical. However given the fact that there is no bearing forward, only a piece of exhaust hose and a lip seal that can move about quite freely, and given that the cutlass bearing must be at least three or four feet aft of the engine and the cutlass bearing is maybe five inches long. Also given the fact that the engine is mounted flexibly. I would say that the alignment needs to be such that the shaft slides without force into its coupling would be good enough. In my story above the engine was solidly mounted on hardwood blocks and there was a grease gland bearing at the forward end of the shaft. Alignment was very very critical. In your case it will not be so critical. I still think however that the technique to centre the shaft with a temporary nylon bearing is a great way to get the proper datum from which to work.

Regarding the squeak being between 1500-1800 rpm. It would not surprise me if either the prop or the shaft, or indeed alignment is the problem, or even all three.

It is out of the water currently so I will try your proposal of the temporary bearing while out first when I get back to the boat and then check again once I get back in the water.  Will also get the prop shaft checked.

I have one other question if you could help.  Due to the prop shaft generator the belt pulley sits between the vetus coupling and the transmission.  I have attached some photos from another post that shows the arrangement.  from memory the 4 bolts shown on the photo "vetus coupler" bolt through the coupling and the pulley holding it all in place.
When measuring the the alignment access to the back of the transmission is limited due to the generator pulley.  I am not sure if there is enough length in the shaft to pull it forward without the pulley in place.  Do you have any thoughts on this?

Also it is only at certain revs that the squeak was occurring.  Very low revs and then between 1500-1800.

James,

    I thought of one more thing that possibly could be causing the noise.  I installed a cutlass bearing once that was a bit on the tight side,  apparently a manufacturing issue.  The Cutlass bearing made what I would call a “chirping” noise for while as it wore in.  Might be worth spinning the prop before you launch and listen for noise from the new cutlass bearing.

   Best of luck in solving the mystery squeak,  let us know what it turned out to be. 


Best,

James

Re: Power Failure

 

Dennis, that created a dead short of the house bank. Something melted because there is enough amperage in the house bank to weld. Look for a burned wire. Also, try to find the shunt for the battery monitor. It may have blown because on your boat it is probably rated at 12 volts 200 amps or less...a dead short would have been more than 200 amps. It will be on the negative side. I am not sure if it will look burned, but you should check for continuity between the two large posts. I am not sure, but I think if the shunt is burned, the monitor will still work because of which side of the shunt it is connected. The shunt will look something like this and will be located close to the batteries:

It will be wired something like this:

Good luck.

Hi Pat,

I would suggest you do not attempt to add a grease fitting to the Racks. The steel racks take up almost all the room inside the black housing they are fitted into, and I’m not sure you can find a place to put the nipple.  Even if you could, the grease is not going to circulate adequately around the racks. When I took my racks apart, they were still packed full of grease after 27 years. If you are losing a lot of grease from your racks, something is probably not right, and you should take them apart. If you are just losing very small amounts of grease, don’t worry, the racks are very full of grease. 

Just my two cents worth, but having replaced my entire steering system (racks, pinion, and cables), I have a fairly good understanding of how it works.

Pat,

I haven't considered that. I assume that you are referring to the racks...the steering cable is sealed.

I assume that the "leaking grease" is coming from the rack housing at one end or the other. If I recall these ends are not perfectly sealed. And as the toothed rack moves back and forth, it could push excess grease toward the ends of the rack housing.

Keep in mind that it is the steel toothed racks inside each rack housing that will fail with excess wear and that excess wear will be very close to the center of each rack. I believe this is wear caused by the autopilot "back and forth motion." It may also be caused by securing the helm in a center position while anchored.

Amel SAV said that they are going to be sourcing these steel toothed racks and have them available, even though the original manufacturer, Ultraflex, has stopped producing them. See the worn rack below:

One rack has teeth pointed upward, the other rack teeth are pointed downward. Tooth orientation, along with primarily 
center wear, should be considered when adding grease/fitting.

Possibly, the cover shown below can be drilled to inject grease. If so, this would be a fairly easy modification that could possibly add years of service to the racks. 
I am worried that the metal is to thin to take a thread tap. If that is true, possibly it could be drilled, grease injected and a rubber plug inserted. I know there are a few owners who can answer this question. We may need a volunteer to study this further.

Pat,

I haven't considered that. I assume that you are referring to the racks...the steering cable is sealed.

I assume that the "leaking grease" is coming from the rack housing at one end or the other. If I recall these ends are not perfectly sealed. And as the toothed rack moves back and forth, it could push excess grease toward the ends of the rack housing.

Keep in mind that it is the steel toothed racks inside each rack housing that will fail with excess wear and that excess wear will be very close to the center of each rack. I believe this is wear caused by the autopilot "back and forth motion." It may also be caused by securing the helm in a center position while anchored.

Amel SAV said that they are going to be sourcing these steel toothed racks and have them available, even though the original manufacturer, Ultraflex, has stopped producing them. See the worn rack below:

One rack has teeth pointed upward, the other rack teeth are pointed downward. Tooth orientation, along with primarily 
center wear, should be considered when adding grease/fitting.

Possibly, the cover shown below can be drilled to inject grease. If so, this would be a fairly easy modification that could possibly add years of service to the racks. 
I am worried that the metal is to thin to take a thread tap. If that is true, possibly it could be drilled, grease injected and a rubber plug inserted. I know there are a few owners who can answer this question. We may need a volunteer to study this further.

The cables are sealed.

The racks and pinion have to be disassembled to add grease.

Re: Prop Shaft Squeak

James Alton
 

James,

   I replaced the original Amel engine mounts on my Maramu #220 this year.  The part you have circled is the bronze stern tube which will extend into the hull.  It appeared that mine was bonded and glassed into the hull, it needs to be a rigid connection.  The stern tube provides the attachment for the short pc.  hose that the stuffing box gland attaches to, it is not supposed to be a bearing.  There should be relatively even clearance between the stern tube and the shaft which allows for some engine movement without the shaft touching anywhere.  As I understand things the cutlass bearing on our boats forms the aft bearing and the transmission bearing provides the front bearing to support the shaft.  Nick already mentioned the two most likely causes of your squeak but I will try to elaborate a little more.  Engine alignment is more than just getting the two faces of the coupling mated within a few thousandths, you also need to position shaft so that it is riding close to the center of the bronze stern tube so that it cannot touch.  The fancy way to set up this alignment is to remove the stuffing box and the short pc. of  hose and fit something solid like round rod of the right OD to hold rigidly hold the shaft in the very center of the stern tube, then to adjust your engine so that it is the correct height and also correctly positioned Port and Stb.  Once this is done you can do your actual alignment to get the coupling faces aligned.  An easier method that seems to work fine and can be done in the water is to decouple the shaft and by HAND force the shaft coupling to go as far as it will go up down and Port/Stb.  You will feel solid contact as you force the coupling to it’s limits as it touches the inside of the stern tube.  Note the relative displacement of the couplings to Port/Stb. and Up/Down and adjust the engine so that the displacement is the same top and bottom and side to side which will put the shaft pretty close to the center of the hole in the stern tube.  Once this is done,  align your coupling faces.  Also I initially only did a rough alignment on my engine because I knew that the new mounts would settle a bit and they did.  So after 50 hours I did a second alignment and sure enough the whole engine had settled a bit so brought it up.  

   As to the other possible causes of the squeak,  as Nick alluded is that the shaft could be bent.  You can often tell this when sailing with the engine off and the wheel turning.  If the back of the engine is moving around much in time with the shaft rotation, you could have a bent shaft,  if it is nice and smooth then probably not.

   One final possible cause of a squeak can be from having the stuffing box too tight.  With the new teflon packings you can pretty much tighten to the point where you don’t have any leakage but if you go too far the box begins to heat up, grab and squeak.  

Best of luck,

HI,

The attached photo is of the stuffing box and where the shaft on my maramu exits the boat.  Is the circled part another bearing that is glassed into the hull?

We have a "sqeak" or hum when the prop shaft is spinning at certain revs (both with engine and when sailing and free spinning) that we have not been able to diagnose.

The problem started following the failure of our engine mounts.  The engine mounts have been replaced and the cutless bearing was replaced at next haul out, however a squeak has remained on our last short cruise before hauling out again.  I have checked the engine alignment, the stuffing was replaced, but the squeak remained.

We will be back on the boat again in the new year and would like to eliminate the cause for this before going back in the water and if this is a bearing then possibly order one now.

Re: Prop Shaft Squeak

Hi James,

1.  If the boat is ashore I would check that the shaft is true. You would need to pull it and take it to a machine shop.

2. I would check the engine alignment again. It is not easy to get spot on. One of the tricks I have learned is to decouple the shaft from the transmission and centre it within the stern tube. Then align the engine to the shaft.

On some systems the shaft is floating around and can be moved a lot as there is no bearing at the engine end of the stern tube. This would be the case with a modern drip free lip seal style stern gland. From the photo I think this is what you have. If there is shaft wiggle then make up a nylon bearing that slots into the stern tube at the front end, this involves removing the shaft seal, and sliding the nylon bearing over the shaft and into the stern tube. So there is a cutlass bearing aft and another nylon temporary bearing forward. This then centres the shaft spot on within the stern tube. With the shaft centred you then align the engine to it. It needs to be spot on. Then obviously remove the temporary nylon bearing, and put back the shaft seal.

The problem is that  it is much easier to do out of the water but the hull may take up a slightly different shape ashore, although if it has been carefully chocked and is nice and level a solid hull like a Maramu will probably not move much.

If in the water, I have used a  greased tape or plastic wrapped around the shaft and pushed into the cutlass bearing to reduce the flow. This works quite well, but water leaking into the boat adds a bit of stress.

There are other techniques, but this is my preferred.
