Man that thing was a major PITA. I even threw it in the stove for 20 minutes and it was still a bitch to go on. I hammered metal to metal but I did not hammer too hard and I held the hammer close to the head so I didn't have much leverage. I know it's a no no but most likely it's okay. What would I have been hammering against by hammering the hub on the front of the crank? I mean where would the pressure be? You now before that I tried using the hub bolt to pull it on and I first stripped the beginning 2 threads... then later after I thought I had it worked out I stripped about another inch of threads backing the long bolt out to put the stock bolt in. I already stripped the hole twice and had to install a helicoil just so I could get a bolt to thread in (that stupid helicoil kit was 40 bucks and it looked like it cost 5 bucks to make, arghhhh ). I can't believe out of the entire cam install the hardest part was taking out and reinstalling the hub and scraping the old gasket off the timing cover... that's just ridiculous. Ehhh I just had to bitch for a while.

 

That hub is a bear to remove and reinstall. I fortunately had some help from a bud who had some specail tools that made the job easier. I smeared the hub snout with anti-seize and found I didn't need to heat it up. We used a hub tool and screwed it in.

I also installed a keyed hub this round. Do you have a key hub?

I helped a bud install a hub after a cam job a few years ago and we heated the hub in the oven and it went on very easy (with insulated gloves!)

 

Next time, use a threaded rod to put the crank hub on. that way if you destroy any threads, it will be on the threaded rod.
