Iíve decided to replace my Hurth transmission
and damper plate (yes, I know these transmissions can be rebuilt, but for various reasons I donít want to go there so letís try not to discuss rebuilds in this thread as there are several existing threads already doing so). As far as I can tell, it has nearly 4,000 hours, which I understand is almost unheard of for a Hurth
. Although itís not in dire straits, itís showing some age related symptoms and I donít want it to fail next season when I plan to do some longer distance motoring. I was hoping to hire the project
out, but Iím having a hard time finding a local mechanic
to even return my phone
calls or e-mails, so Iím going to have to climb the learning
curve and take this one on myself. To install a new unit of the same model looks like a fairly straightforward process of unbolting and rebolting although Iím sure as a novice
it will take a lot more time than I expect or want it to.
A couple questions I've been wondering about...
Should I haul the boat to do this? I have the Volvo-Penta shaft seal
typically used on Beneteaus. Itís not leaking now and was replaced fairly recently. I assume the shaft can be slid aft but I worry about this creating a leaking situation.
Will I need to re-align the engine/shaft? Although the new transmission
will be an exact replacement, I assume there are some differences in manufacturing tolerances but am not sure if this is enough to require realignment. If I do have to realign, any tips?
Any other tips from those who've been down this road would be greatly appreciated!
