Anyone know a good way to seat that hub fully on the crank? I got it on last time by using a longer crank bolt to pull it on, but I'm so afraid of stripping the threads or not seating it all the way. Anyone happen to know the way GM actually does it? I might call them tomorrow, but wanted some other opinions.

 

GM techs use a hub installer. You can make a basic installer out of some high grade threaded rod/nuts/washers. Grind a taper on the end of the rod and thread it all the way in until it bottoms out. Use the nut and washers to push the hub on. If you weld a nut on the end of the rod, you can use that to hold the rod still while you twist the nut. Why is this better than using the bolt? Because the friction is transferred to the nut and threaded rod, rather than the bolt and the crank threads. If anything strips, it won't be your crank or bolt.

 

Very cheap yet very effective crank hub install tool:

Something else for the rest of us: I never use just the bolt to install the hub. Ill put the bolt in, snug it up, tap it a few times (rubber mallet, or something gentle) snug the bolt up again, tap it again.

Takes a minute longer, but I don't feel like I am stressing the threads.

Yes I know not to beta the hell out of the end of the cank for bearing reasons etc, I said tap it on.

 

I bought a 36" section of #5 grade (hard to find) 7/16" 20 TPI threaded-stock and made several hub installers. Also, I've sent some forum members hub installers I've made from that section.
