I have a 2005 440 chassis w/2003/800 engine installed.
I run Aaen pipe system and have to run 55 pilots to keep rpms at 2000 for idle.
Lately the idle has been going up to 3000, then 3500, then 4200 and ok this is ridiculous.
I look down at the crank seal and it's rubbing against the clutch.
I pull the clutch off and pull the seal out with my fingers, there the crank bearing grease is all grey, it should be at least some white in it, nope, stinky burnt smell and all silver grey.
Im cleaning the bearing and what-the-fk-is-goin on...the outer race of the bearing is able to spin in the case.
I pull the engine out and strip it down today. Hmm, looks like there was a previous crank failure and a few other bits of turbulence with the owner before me.
I try the bare crank in the block and see that there is clearance, the bearing spun in there before.
Im pissd, only 550 miles on it and this happens.
I already drill/tap the block to make a seal retainer.
How can I fix this? Every time you get on the gas the bearing is going to end up touching the backside of the case and im sure it strains the crank bending in a torsional load like that. The bearing vibrating against the case causing more aluminum material to wear away and contaminate the grease.
Do i have to buy new cases?
Can I use green bearing loctite to take up the clearance?
I wonder if there is a Timken ABEC bearing with larger outer race diameter to take up the room left over.
heh heh heh, wrap super thin shimstock around the bearing when i put the cases together?
ARRGHHHH, im missing some bitchin riding as the snow up here is darn deep now.
