Ok, well I’ve been working my to the center of the IRS; and I’m to the point of replacing the Differential output shaft bearings. unfortunately the crush collar is crushed and is prohibiting the outer bearing from “just sliding off”.
Since this is my first IRS rebuild so far, I haven’t run across anything too difficult to comprehend - just a lot of pieces to keep track of. Oh, and it didn’t help that the PO put the carriers together wrong. I’m not 100% convinced these carriers are going to last. I won’t go on about the JBWeld inner seal retainer. or the fact that the inner grease seal ring (on one was stuck on the halfshaft while the other side was left to spin. It is a tight fit, but not tight enough to keep it from spinning on the output shaft where the wheel hub meets the half shaft. So which is it? spin while not under load, or be stuck on the input shaft of the half-shaft…? I do digress as usual…
Diff housing output shaft bearings. I halft to say I was a bit surprised to discover these bearings are completely isolated from the diff lube; and require their own grease. Hmmm…
Again, back to the question at hand. putting these things back together. Obviously I’m going to need a new crush sleeve. According to The Book of Green, it states to lube everything up, assemble it, install the inner nut (not tight) take a torque reading of the inch lbs required to turn the output shaft (with the nut loose) then gradually (with a torque limiting screw driver?) continue to tighten the nut while maintaining the recorded torque (the nut finger tight). continue to tighten the nut until nearly all the end play is taken up and the crush sleeve is, well, appropriately crushed… This is severely paraphrased.
that all being said.
A torque limiting screw driver or wrench that can be set to 4-6 inch pounds? Seriously? I don’t have one (mine starts at 10 inch lbs) and I don’t think I’ve ever seen one. Even if I did have one, or found one, it’s probably 1/4 inch drive and the nut that I’d be turning is 1-7/8’s. I can’t say I’ve ever seen a 1/4 drive 1-7/8 socket. oh, and it has to be REALLY deep to fit over the output shaft splines. Rant over.
Is there an alternative way that the preload can be set?
I’m open to suggestions. Oh, I did note the number of threads, and marked the nut and the output shaft before I took it off though with new bearings, I’m not too sure those marks will mean anything.
Again, Open to suggestions.
As always, very grateful.
