Hi again... Volvo penta 4.3 GL I have a clunking noise in the engine, quite loud...after a bit of investigating, rods / lifters all good... with intake manifold off the sound seems to be coming from the rear of the motor...clunks with a manual turn as well... every rotation.
Thanks will update when I get time to pull engine.
FYI...... with the V/P cone clutch system, spining the propeller rotates the lower gear set, the vertical shaft and the upper gear unit sliding sleeve only.SternDrive..SX... no noise when I spin the prop
Good suggestion. Universal joint "bearing crosses" or the gimbal bearing!Do you know how old the u-joints are? Ricardo would have a better idea but I would pull the drive and see if the noise goes away I am thinking it is a U-joint or PDS bearing?
Thats a good start the crosses and gimbal bearing are common wear items it would give you piece of mind knowing their condition. Ricardo forgot more about VPs than most people will ever know
Kim, thank you for the kind but eggagerated words!
So here is the update... the flywheel had play in it, retourqued the fly wheel and coupler play has been removed...
Question; the coupler isn't level to the flywheel... is this normal? also the outside housing of the coupler is out of round?
What do you mean by "coupler isn't level with the flywheel" and "is out of round"?
Is the coupler face not parallel with the flywheel face, and are you seeing run-out at the coupler?
The coupler face should fully mate up to the flywheel face, and the coupler should not oscillate any..... at least not to the *****
eye.
I did, compresion was done with cold engine 100 to 120 on most with one at 90.
