Car Forum / Jeep / March 200795 YJ timing chain questions
Daughter is replacing her timing chain/gears on her 95 YJ, 2.5 L, we have everything off to do it, but can't get large gear off, they both slide out easily about 3/4" then large one stops dead, you can acually slide it back and forth making it clunk. We have Hayne and full shop manuals, we've followed them to this point. Can't see behind gear enough to see if there is a clip, and books don't say there is, so any ideas? > Daughter is replacing her timing chain/gears on her 95 YJ, 2.5 L, we have > everything off to do it, but can't get large gear off, they both slide out > easily about 3/4" then large one stops dead, you can acually slide it back > and forth making it clunk.

I am thinking the key is stuck either in the pulley or on the shaft, but most likely in the pulley.

I know the small gear is keyed on, but the big one has a 1/2" bolt holding it on. >> Daughter is replacing her timing chain/gears on her 95 YJ, 2.5 L, we >> have everything off to do it, but can't get large gear off, they both [quoted text clipped - 12 lines] > Jan/06 http://www.imagestation.com/album/pictures.html?id=2115147590 > (More Off Road album links at bottom of the view page) My book isn't clear on that, but the pulley has to fit on only one way doesn't it? I have seen keys rock in the slot jamming like you describe anyway. Mike > Is that shaft keyed? I know the small gear is keyed on, but the big one > has a 1/2" bolt holding it on.

Yup. putting needless bite marks on the lobes and lifters.

And yes we are removing all as a unit. > It uses a pin rather than a key, and is very narrow on the cam, meaning > it must be like a press fit to keep from whopping and wearing out: [quoted text clipped - 12 lines] > is >> a clip, and books don't say there is, so any ideas? It looks as if a small to medium two-jaw puller might fit. Book just says, "Remove the crankshaft sprocket, camshaft sprocket and timing chain as an assembly". Like it would be easy. Don't forget to line up the marks first. Earle > Is it a special puller?
