Question about 1989 Jeep Cherokee

Harmonic balancer rubbing on the timing chain cover

I recently bought a 89 jeep cherokee 4x4 4.0 L. I noticed some motor oil under the motor. when i looked i thought it was the front crank shaft seal. So i got the seal then when i removed the harmoic balancer i noticed the harmonic was rubbing on the timing chain cover. It wore into it about 1/4 inch. I checked the crank shaft for play but it was well in the specs for movment i was wonderin what could cuase this

The rubber in the balancer has broken down and the inner and outer pieces shift and rub on the cover. You need a new balancer.

I have a vibration damper that needs changing for a 1995 Cherokee Grand


there will be costly repairs if you do not replace the harmonic balancer( damage to the timing chain cover)
The job will be time consuming rather than difficult. You will need a 1/2 inch impact tool to undo the nut as there is no way of holding the crank to achieve loosing the nut by brute force. You will need a balancer puller to withdraw the balancer from the crankshaft There is only 1 way to put the balancer back on as the key will align everything. tighten using the impact tool. Replace the belt correctly

What do I need totake off to get o the timming chain?


You have to strip off the front of the engine to get to the timing. Often, also the brackets (like the alternator bracket), that are in the way.
You will also likely have to remove the front motor mount. This means putting a jack under the oil pan to keep the engine raised (use a piece of wood between jack and oil pan).When everything in the way is removed, the timing cover can be removed to expose the timing chain.
oh yeah, also have to remove the crankshaft pulley-use a harmonic balancer removal tool for this.

Replace timing chain


remove radiator and hoses, remove enough accessory brackets to get to water pump, remove waterpump & harmonic balancer, take timing cover loose,loosen oil pan bolts(take about the first 3-4 completely out and loosen the rest), reinstall harmonic balancer bolt and line up timing marks. cylinder #1 at top dead center and valves for cylinder #1 closed. remove harmonic balancer bolt and remove cam gear bolts and crankshaft gear, install is reverse order..

How do you replace a gasket and cover for timing chain and rear seal gasket for oil pan on a 1978 Chevy 350 motor


the oil pan will need to be removed to repalce the rear seal, so replace the front seal and gasket then, replace the timing chain/gears if sloppy, then reinstall the oil pan.

Power sterring will not line up with other pulls


is it a 4.0l 6 cylinder?
if it is then its not the power steering pump pulley, unless it has been removed and reinstalled incorrectly.
the harmonic balancer has come apart [crank pulley] the rubber insulator between the center and outside parts of the balancer has deteriorated and the outer ring has moved forward or back.look at the inner edge of the balancer were the belt rides,there is a timing marker on the timing cover the inner edge of the balancer should be just a bit under the timing tab.if not or you see rubber sticking out of balancer face then replace balancer
a common problem on 6 cylinder jeeps
