Perkins/BUKH info

[DwM]

Hello all

Does anybody have any info on the BUKH transmission that is used with the Perkins 4.108 engines.

I'm working on a 1985 Grand Soleil 39 and it looks like the forward clutches are slipping under load. It shifts perfectly and motor runs great had diver look at prop (Max-Prop) was told it was fine.

Have taken a peek inside and all looks good except the fwd clutch pack seems slightly darker. Only makes 3 or 4 knots forward then engine pulls through unloading reverse works great.

Have looked about the web for a diagram for the trans and all I find are the outside line drawings.

Looking to find out if the clutch packs are serviceable without hauling her out?

Are you sure it is a BUKH transmission?
Would have thought more likely to be a PRM or maybe a Hurth.

Yup says so right on the top. No model number anywhere to be found though

This is an old Bukh saildrive that Bukh build themselves. You can contact Bukh direct for any parts and manuals.

Alternatively there is one gentleman that I know who rebuilds them in Italy. Contact ScanDiesel and speak to Attilio Origo. His English is excellent and his email address is info@scandiesel.it
