Intermediate Shaft Assembly

[The Dude]

I posted this over on the rebuilding forum and haven't got an answer yet.
----------------------------------------------------------------------------------------------

Couple of questions re: the intermediate shaft assembly.

-- Is the oil pump connecting shaft symmetrical? I.e., does it matter which end I attach to the oil pump or intermediate shaft? One end has the grooves extending 18mm and the other has them for 17mm.

-- I can only find one circlip from the disassembly process; its located on the intermediate shaft side right now. Do I need one for the oil pump shaft side too? Where to get one of these little buggers?

-- There's a little damage to the big gear on the intermediate shaft. Pix below. Is this OK to keep?



Thanks guys.

That Intermediate Shaft gear looks like it was dropped on the floor. I wouldn't use it.

Not sure about the shaft question but, don't use that gear.

Landon,

If you need another IS assembly, I can send an extra one I have to you.

It does not matter which way you put on the connecting shaft. It just floats between the int. shaft and the oil pump. The circlips are there to keep it from walking too far one way or the other, keeping it centered over the machined spline areas. You should find a circlip to replace the missing one. I would imagine it will be in your dealers parts book. Probably only a few bucks. Outrageous for a 15 cent clip, but won't bankrupt you.

I wouldn't pass judgement on the gear based on a single photo. Replace it if you want. On the other hand, if it is just a few teeth damaged on the edge, you can dress them with a file and use quite successfully. I've seen quite a few motors come apart with terrible looking gears (chipped teeth and big gouges, from swallowing chains) that seemed to run fine and with no apparent ill effects. On the other hand, that gear is relatively cheap to replace. Depends on your intent for the motor. An all out no expense spared 7500 rpm 300 hp monster. Or a get it back together cheap and drive it T motor.

Of bigger concern might be the sprockets. It may just be a trick of the light/camera but it looks like some of those teeth are worn or damaged on the sprocket to the right. Its always amazing to me when I place a new sprocket next to a worn one and see how much wear can occur here. Between wear on the sprockets, and wear of the chains themselves, it can sure make a big difference in the operating geometry of the tensioners and idler arms.

Thanks everyone.

Dana, I'll PM you.
