Title: 460 Berkeley
Post by: kpingree74 on July 08, 2015, 02:24:22 PM

1979 southwind I have a loose drive shaft from the u joints to the block u joints are ok and the main is tight to the flywheel any ideas?

Just curious on the choice of bolts with split washers to pto... Most use a bolt that will reside into the hole like a 12pt or allen head without washer an some blue/red threadlock.

That only works on the resessed send holes on the pto to flywheel. The driveshaft to pto isn't reassessed.

Chevy, Ford,  Olds,  MOPAR, Nissan,  Toyota,  Hyabusa. I don't care who's engine it is, you cannot bottom out the spline yoke without damaging the engine.

Would sliding the motor mounts up work or just run a new u joint assembly?

Unbolt the drive from pto an slide the drive into pump till it bottoms out...measure how far its from pto. You want at least a 1/4". If its less you need to either move the motor forward or pull the drive an machine a bit off the end.
