This is really Mickey Mouse!!!!! The sleeve is made to repair the balancer's seal surface. I'd throw it away, and buy a seal from your local auto parts store. There are no guide pins like on all GM and Ford engines, so you must have your balancer in place before tightening the cover's bolts. Replace the timing chain while you're there:
Thanks Bill...
The sleeve is only necessary if the balancer has a groove worn in it where the seal rides. The sleeves are pretty easy to install. I normally put the balancer in the freezer and the sleeve in the oven just to reduce the press fit a little. Then just tap in in place with a flat piece of wood and a small hammer. Some of them also come with an installation tool.

On an 88, they figure the harmonic balancer will have a ridge worn in it at the seal. You can check yours with a straight edge once you have it off. A hot sleeve and a frozen balancer make it easier to put on if needed.
The only other real trick is to have the harmonic balancer slipped in place when you start tightening down the cover so the seal centers. You have to pull it off to finish bolting the cover down, then put it on the last time.
Oh, pulling the rad out will also save your knuckles and is well worth it... Only a couple bolts up top on the crossbar and out it comes.

Thanks Chris and Mike. Thought it was probably for the HB, just thought I would check. Replaced the balancer last year as it was starting to separate, so it is good.
Rest of job looks like it should be ok Thanks again.
