[C320-list] Transmission Replacement- Perkins M30 Engine

[Warren Updike]

I considered that option. However, the ZF 10 is some amount longer fore and
aft so that the shaft is extended by that amount. I forget what the
difference is, maybe 10mm, but the result was that the length of the shaft
aft of the strut exceeded the 1.5 times shaft diameter recommended.  I
didn't want to deal with removing and cutting the shaft.  I went with the
rebuild.

Or get a ZF 10, the replacement for the Hurth 50 that came with the Perkins.
It's a much better match for the 29hp Perkins than the Hurth 50 which is
equivalent to the ZF 5. ZF no longer recommends the ZF 5 or 6 for our
Perkins engines. ZF acquired Hurth some years ago.

Jim, I've been away 3 weeks and just catching up on the list. There has not
been much traffic on your question, perhaps, because of the age of our boats
(mine #62,) and there weren't all that many Perkins installations.

I can address the symptoms you describe and I have a fixed prop. Assuming
the prop or hull fouling is not the issue, perhaps you have worn clutches. I
don't know if the same clutches are used in fwd and rev.  

You need a transmission guy to discuss this with. I had mine rebuilt for
about half the cost of a new trans because of a leak. If Annapolis is
convenient to you I can give you the name. Otherwise, look for a Perkins
trained transmission shop. They do exist. 

To continue this discussion, contact me off-list.

Paul,

I had low power from the prop going forward, but had plenty of power in
reverse.

I went under the boat two weeks ago and cleaned the bottom and the prop. I
have a Two blade feathering (martec) prop that is adjustable for pitch. The
prop was in good shape and function correctly.  

When running the boat there is no unusual vibration and I have the normal
power in reverse, so I do not believe that the prop is damaged or fouled.
The only thing that could be related to the prop is if the pitch setting
changed for forward, but this seems to be unlikely ( still need to check
though).

The shift  on the transmission appears to be moved into forward correctly.


Jim

Jim, can you share the reasons you think you need a new transmission?

i All,
The first trip of the year didn't go to well, as it appears that I may have 
ransmission issues. I still need to check a few things and hopfully it is a 
imple fix, like a minor adjustment on the shift cable. 
But incase it is not, If anyone who has the Perkins M30 engine had the 
ransmission replaced, could you please give me the make/model of the new 
ransmision that was used as well as cost and installation costs, this would 
ive me a better idea of what to expect. 
I remember there was some disscussion a while ago concerning replacing a 
ransmission but I don't think it was on the perkins.

hanks in advance
