Well, I was able to make it this far only removing the passenger wheel, crank pully, some water jacket cover thing and the timing cover.

I suspect from all my reading that was the easy part. It almost looks like Id have enough room to get in with a torch and a puller but would this be ill advised? I dont have any engine hoist and would prefer to disturb as little of the electronics and vacuum hoses as possible. Before the gear went, it was running fantastic.

Of course, if I must pull the whole cam, I have to do what I have to do.

Any idea why gm chose the press on as oppossed to a bolt on hub? Was it to make the shops money ? This would be an easy job if that were the case.

Air hammer and chisel the gear off. You can use a die grinder or dremel but it will take longer. Then, take a propane torch and heat up the hub of the new gear for 90 seconds. It will expand enough to slide the new gear on the end of the cam. You gotta do it fast, like 5 seconds fast

I've done it exactly like this a dozen times

Excellent. That is simmilar to what I had in mind though I was going to drill and tap the gear, then use a timing gear puller to get it off, then heat oil in the dutch oven to heat the gear. think pulling it cold would cause damage to the shaft? I imagine you only got one shot to get the new one on then (cue Eminem-lose yourself).

It might be worth the investment for an air hammer then. In honesty, I dont think I can get a drill in tthat space anyway.

Ill probably have to wait a week or two, but cant wait too long. Its on a slab IN The back yard

The gear breaks easily, it's the metal hub that is hard to get off

There isn't enough room for a puller without tilting the cradle down. If the gear gets stuck halfway while putting it back on, heat around the hub and pull it back off. Where a glove, that thing will be hot
