How hard is it to change timing chain?

Jeepinjon · 01-27-2007, 08:09 PM

So how difficult is it to change the timing chain in a '95 2.5l? Will I have to deal with oil or coolant? The only place I have to work on the Jeep in the winter is at work but I can't be spilling oil and coolant in the backroom with $100's of thousands of dollars of fitness equipment all around. Any tips on this would be great appreciated as this is a problem that is only getting more and more annoying.

It cost me $420 at a garage because I didn't feel like dealing with it.(Too cold for me with no garage). It's was driving me nuts for years. Check this link out. http://www.autozone.com/servlet/UiBroker?ForwardPage=/az/cds/en_us/0900823d/80/1f/e0/a1/0900823d801fe0a1.jsp

the haynes manual has a good description of the process. should be fairly oil free and definately coolant free.

If you can do the following steps without removing the radiator, you can get away with a fairly clean job:
1. Remove Fan & shroud,
2. Remove Drive Belt,
3. Remove Vibration Damper,
4. Remove Timing Case Cover,
5. Rotate the crank to line up the two timing marks on the gears,
6. Remove Oil Slinger,
7. Remove Camshaft retaining bolt & now the two sprockets and chain come off as an assembly.
8. Install new chain and assemble in reverse order.

Curious? What's the problem with the chain?

You will need a harmonic balance type puller to get the vibration dampner off..

Not a hard job at all - as long as you have the tools to do it.

I suspect the chain is worn and maybe a little stretched. I had the timing checked and it's bouncing between 2 and 4. The mechanic told me if he adjusted it the computer would just set it back anyway. Then he said that it probably isn't the chain; if it was then it would run like crap all the time, not after a few minutes. My arguement is this: If the computer sets the timing after the Jeep is turned off...wouldn't it run fine for a few minutes and then start to lose power and backfire if the chain was worn?
Anyway, if I'm wrong I'm out about $30 with a new timing chain and gears and the new found knowledge. If I'm right, which I hope I am, then the Jeep will run better and I'll have some bragging rights. Well, not really but the Jeep will run better.
