Intermediate shaft / oil pump runout check.

[reclino]

Ok I have carved out time this weekend to work on the engine. Plan is to check backlash on the intermediate shaft gears and then I read this step. This seems related to my previous question about alignment between the oil pump shaft and intermediate shaft.
There are no explanation on how to measure this "runout" but the adjustment is "Keep changing spline connection on parts until smooth running is reached"



Does anyone do this step and have a better explanation or pictures/video?
I am probably over thinking this, but there is a bit of free play between the studs for the oil pump and there corresponding holes, so the oil pump alignment to the intermediate shaft is floating until the nuts are snubbed down and torqued...

Thanks

There is some "wiggle room" with the oil pump. With the oil pump nuts torqued to spec, the "dumbbell" should easily slide back and forth. If it binds up, loosen the oil pump nuts and try again.

As Dan said, the shaft moves forward and aft easily to show it’s not binding.

Also pays to check backlash between the gears. Check out Klassic Automotive Training School videos on YouTube.

Backlash checks out good, bottom of the spec, but that's the way it ran for the first 68,000 miles. Would have been easier without the rods installed but got that checked off



Discovered that I don't have an O-ring for the #8 bearing so now waiting on parts to ship. I thought it was in the gasket kit but nope..... That kit really has let me down a few times now.
