Hi Peer and anybody else who may have this engine
I had a final drive shaft bearing failure.
If your engine has high hours, you will need to check something.
There is a screen
in the bottom of the gearbox
and after years of oil
blowing through it, mine eroded through and sent all manner of crap up into the transmission
bearings, wiped them all out, but the gears are fine. Cost $800 to replace parts
and labor for all the bearings in the gearbox
Please contact me for more details !
Otherwise I have put about a thousand perfect hours on it, no problems at all.
happy boy here !
