Timing Chain!

Time to do the timing chain after looking at it while doing my RM....

I love my jeep!

Any tips or pointers?

Thanks Joe.

just ripped mine apart today to find out I needed a new one bad...there was about a 1/4" play in mine, and the tensioner was "unlocked" and wouldnt re-lock so that meant it was broken....

No real tips, just take off the fan/shroud/altenator (makes things a lot easier)....use a puller to take off the crankshaft pulley (its press fit on after you take off the main bolt and washer) also, dont forget to take off the 3 bolts that are located underneath the timing cover (these keep the front of the oil pan on)....then when you see the 2 timing gears, crank them so the 2 "marks" are lined up so when you put the new chain on, it is easy to calibrate it.

I would suggest replacing the tensioner & bumper while youre in there (along with all the gaskets)

Any questions feel free to ask......

Maybe do the water pump while you are in there.

X2..... even if it ain't leaking..... better to do it while it's apart then do it all over again. i did mine in reverse tho...... water pump needed replacing, so i threw a timing chain in there whils i was at it.....
