Does anyone know where I can get the instructions on how to rebuild my harmonic balancer myself? I have googled the heck out of it but can't find instructions on how to do it myself... and where to get the rubber.
That's a lot like rebuilding a blown-out tire. There is a good reason you didn't find an instructions.Does anyone know where I can get the instructions on how to rebuild my harmonic balancer myself?

I think the Engine Shop forgot to do the machining on the snout and or used the wrong Timing set, now they are back peddling and trying to have me "rig" up a fix for it. None of what they have told me is working.Cut the snout off or get a hat washer.
ATI is the only one that can be rebuilt that I know of
I didn't find anything on a 258 with a serpentine belt.
but this is what i found on the only two i know of.
4.0 pb1439n. 87 and up
nose OD 1.779
crank bore 1.122
overall width 1.870
pulley diameter 6.716
nose OD 1.791
crank bore 1.122
overall width 2.137
pulley diameter 6.712
these are the only two i found. the 2.5 is longer than the 4.0.
the nose is on the 2.5 is a little bigger (0.012)
Crank gear is all i can think of that is keeping the 4.0 balancer not lining up
The machine shop could have easily machined the crank snout to accept the 4.0L balancer. This is a common practice. Either they are not very familiar with stroked 4.0L's or they forgot. Either way I can't believe they are leaving it up to you to figure out.Well, mine is unique. I just got the engine back from having it transformed into a Stroker so the old 2000 balancer didn't work (snout is longer on the 87 so the pullies didn't line up, about 3/8ths off). I need one that fits the 87 4.2 Crank.... I spent 2 hours on the phone yesterday looking all over and finally found one in California for $150 shipped.
....THEN I just happened to get lucky and the local Jeep store (collinsbrosjeep.com) had one for $45, THANK GOD, but it needs to be rebuilt because the rubber is a little old.
Thanks, I was a little concerned with the spacing, I wondered if it could be "to close" but your measurement makes me feel a little better about snugging it up tight.Not sure if this will help. But I can get .090 of feeler gauge between the balancer and front cover
