wrangler yj 1995

I bought a 95 wrangler and the motor is not original. It is a 2.5l jeep motor but I don't know what year. How can I identify the year. The problem I am having is the vibration damper which is also part of the serpentine belt is not aligned. It seems like it may be the wrong part. The belt is wearing badly because it is not in the grooves of the damper. Also, info on how to remove and replace damper would help.

First welcome to the forum. It appears that it doesn't matter (91-95) as to the year. Big difference is serpentine belt or not.

Can't help you with firsthand knowledge of pulling it but there will be others that can here.

Enjoy!

I have a 95 with an 89 engine,on the older v belt engines the crank is longer .when i installed the 89 eng. I discovered this I had to make a 1/4 " spacer to seat the Harmonic Balancer in the proper position.amd every thing else had to be switched out also.all parts from v belt drive .this maybe what is going on the water pump is also different.Longer and also the oil filters are not the same.not saying you have an older pre91 eng. but its something to check.

Thanks. It is an older engine an 87 I think. Everything is perfectly aligned with the serpentine belt except the damper. The shape of the damper needs to be different. It is flush with the timing cover but the belt portion is too far away.

this is a pic of an original 87',



I would really look into the damper as to how it is attached. There may be a way to move it in or out further on the mount with washers, spacer, etc...

If you can, get a couple pics. The crew out here may recognize differences based on how it is supposed to look.

Thanks. Here are the pics. You can see that the damper is out too far and is eating the belt. All else is aligned. I have looked everywhere for a different damper and cannot find one.

Have you looked at the damper on other yj's ? See if you can find someone with a 89 and someone else with a 94 and see what their dampers look like.....if it theirs look like it might fix the issue, try and get a part # off of theirs.

Are the pulley's actually not on the same plane or is the belt just not installed correctly? (i can't tell from the pictures)
Have you tried loosening the belt and moving it fully on the balancer?
I'm not sure. but the ridges on the pulley may not allow an incorrectly installed belt to center itself.

Also, The top alternator bolt does not appear to be tightened. It's sticking out a little. This could cause the belt to track incorrectly.

They are not on the same plane. The belt is installed correctly. I cannot find anyone with a damper different from mine. I have looked at all the parts stores and on line extensively. The dealer says the older one is discontinued.

I looked at my damper yesterday when I was messing around with my 94 YJ. My damper appears to be diff than yours......I might be wrong, but it appears that you have one that looks very similar, but not exact to the one on mine. I'll try to remember to get a pic tonight when I get home.

If you look at the close up of the damper you can see it has what looks like a spacer section right next to the timing cover. That is the distance the belt is off. If I can find a damper with out that spacer section I think I would be good.

Yoo definitly need a 95 harmonic balancer.And you will alsoo need to make a spacer to get it spaced properly.I have to check my pics ,already done it .I took apiece of 1.25" sch 40 and cut a .25" piece off of that to seat over the crank.and keep it form walk off the crank. the reason I used the pipe is it cleared the key way perfectly.

hmmm... thanks for the pics. Is it possible to put the balancer on backwords? You'd loose the 1/4" or so if it would flip over as it has an offset belt path.

Sorry .The crank in the older engines is longer.same as they water pump.and another differance is the oilfilter.95 filter will not work .all yea the oil pan is also diff.the reason I decided to use the pipe is to keep the dampner pulley in its position on the longer crank.heres the pics.The spacer is behind the origanal washer

Thanks very much. You have been helpful. When I take the old one off to replace it what do I need to look out for? Do you have any tips?

Thanks to all. Since you have proven your knowledge I have another problem. There is an oil sensor behind the alternator that has a rubber seal and a wire in the top. The rubber grommet keep popping out and leaking oil everywhere.

I cannot find the 95 damper except at the dealer. They want $150 for the damper. Does anyone know where I can get one. None of the online parts places seem to have it.

Does anyone have any cool tricks for removal of the crankshaft bolt when changing the harmonic balancer? Obviously the motor spins. Photos would be cool.
