Question#1.... From what I see the W33 was equipped with an electric lift
or priming pump, a small canister type secondary fuel filter
and the usual collection of pipes, banjo bolts and washers and an inline high pressure fuel pump
. Most likely if it is weeping fuel
it is not coming from the high pressure fuel
pump, but rather from other sources. This means it's a matter of going thru the system replacing old cracked rubber hoses, gaskets in the filter housing, distorted banjo bolt washers, etc.
Question#2 ...The online W33 parts
book shows that the front and rear crankshaft seals
on the engine are single
part lip seals
which normally don't present too much problem to replace. I think that access to the parts
is going to the major hassle. If the engine is equipped with the Hurth
, then you will see that the prop shaft actually travels up thru the gear
housing and the prop shaft flange is on the front of the gearbox
. That means the prop shaft will have to be pushed part way out to enable the the gearbox
to be removed for access to the flywheel and the seal hiding behind the flywheel. Not impossible, but maybe not too much fun!
Good luck with it!
