Timing Chain cover alignment

I've got an 85 CJ7 with the 258. I just replaced the timing chain and am getting ready to install the timing cover. The FSM calls for using an alignment tool to center the timing cover around the end of the crankshaft where the vibration dampner goes. What's everyone do for this step without having the special tool?? I've also got my oil pan off so there's some wiggle room for the timing cover.

I am doing this soon and would like to bump for info. Also shadoow, how did this go for you? Do you have any links to write ups? I have been searching the forum and google and no one has a good step by step write up on how to change the timing chain.

Just install the cover with a couple of bolts loosely. Then install the harmonic balance, torque all the bolts you can access, remove harmonic balancer, torque bolts you could not access.

I loosely install the 2 shouldered bolts and line up the oil pan gasket rails flush to the block and cover then tighten everything. I have not had any leaks yet.

No links or anything. It's pretty easy once you get to the point of pulling the harmonic balancer then the timing chain cover. The FSM covers it in good detail and there are posts on this forum that have links to a PDF of the FSM.
Getting to the point where u can remove the harmonic balancer is the pain!! First I removed the alternator and loosened the PS pump to be able to later remove the belts. Then I removed the fan, then radiator. Took the belts and fan hub off & was ready for the balancer.
Others may have other ways, but that's how I got there.

I just pressed on my balancer after the timing cover was already on tight. Seemed to just slide on through the seal no problem. I better make sure I ain't leaking any oil from there. Oops
