I don't know where you measured - the bolt comes out and don't forget to take that big flat washer that's under the bolt out BEFORE you try the puller! Once the bolt is out, there is a centering hole in the end of the crank that the puller sits into. Mine is fairly long and the 88 MJ is set up so that the puller screw rides just uder the radiator. That means you are turning the puller with your knuckles right next to the radiator - and that sucker can bite. I drilled a couple of holes in a 3 foot piece of 5/16 bar stock I had laying around and bolted that to 2 of the smaller (about 1/4 inch, but metric 6-8 mm?) holes in the middle part of the damper. That rotated over against the frame and held things nice and solid while I used a big breaker bar and socket on the bolt. Same for touquing it back. If you do use the puiller, be careful with the bolts that you use to attach it to the damper. Mine were drilled all the way thru and if the bolts are too long you can punch them into the timing cover. That's a standard RH bolt, BTW. Also, it's a lot simpler to see what you need to do if you parctice the setup on the new one to get an idea of where all the holes are. DON'T FORGET THAT WASHER - someone here worked for a considerable time before he got around to taking that sucker out and was amazed how easy it was after that <g>. Given a choice, I would have pulled the radiator and used an impact wrench but every one I did had a/c so I would have had a skid plate and the condensor to pull in addition to the radiator - easiler to take a little time and make the holding tool. > > > One big problem: you will probably need some sort of a bar to > > bolt onto the damper so that you can jam that against the frame while > > you loosen/torque the bolt that holds it onto the crank.
