Do the IM bearings have a hole that is supposed to line up with a passageway or something causing a blockage in the flow? Cheers Dan
Anyone have a source for pre-sized intermediate shaft bearings in Canada?
Any carquest should be able to get them, clevite part number SH-1209S.
The bearings have oil holes that must be lined up to supply oil to the intermediate shaft. There is also a slot machined in the rear bearing (flywheel end) to direct a stream of oil to the oil/vacuum pump drive gears. Misalignment of the holes won't directly cause low oil pressure but the intermediate shaft will quickly sieze and slip on the timing belt due to lack of oil reaching the bearings. The intermediate shaft should turn freely by hand if the bearings are installed correctly.
If the IM shaft bearing seemed quite tight perhaps it got caught on the IM shaft and got pushed further into the block than it is supposed to. Is there a step in the bore to prevent this. Just scrambling for what might have happened. Cheers Dan.
