Default crank hub install

Read on here about heating the crank hub to ease installation. What temp and how long does it need to be heated for to make it fit on easier?

You can brew your own correct installer for $20 or so.

Just get yourself some all thread rod, a few washers, some axle grease and install it that way.

The all thread does not have to be grade 8. Not a whole lot of load when installing the hub. A light touch of grease on the threads is all you need.

Pics don't seem to be working, but it should look something like this:

Also if you polish the snout and the inside of the dampener, that helps the ease of the installation, I made a tool like SS made, did the polish, and it went right on.

Using a thrust bearing instead of a bunch of washer works well. You can get them at most box hardware stores in nut/bolt section along with a piece of all thread and a few large washers for either side of thrust bearing

of course the exploding wallet Kent Moore tool makes it all plug & play to R&R the hub

thanks. I was aware of all the options for pulling it on as noted. My question was about the heating process to make it easier to slip on. Several people mentioned heating the hub, but none of them that I could find said what temp oven they used and how long they heated it for.

Nobody gave you that info because its bad info to give. IMHO, getting it hot enough to slip-on may also be hot enough to screw up the hub seal. Is saving $20-$30 worth that? Unless you get it red-hot, you're not going to get it on without having to bang it into place for the final push, and hammering on the crank isn't all that good for your thrust bearing surfaces.

Heating a hub is just not necessary to install. Only reason to heat it up would be to take it off if it's been on the crank snout for a long time and won't budge using a puller.
