Default Need help ASAP!! Thanks

Can't get crank hub onto crank; tried torching it didn’t work. How do you get this hub back in? Thanks

Put the hub in a Oven at 400 degrees for 15 min (or until golden brown). Then put on LESS then a pea sized worth of grease on the crank and ease on the hub, using the bolt that holds it in, as soon as you get it out of the oven. It's served best with potatoes and a light (err, lite) beer.

note: the hub should go back on easily if does not evaluate the situation and come back here.

How can you avoid not melting the seal doing it that way?

Either get a longer bolt for crank to drive it on or tap it with a hammer lighly until your bolt will reach. Make sure you use a little grease.

ahh right, hammer, yeah i used a 2x4 and hammer to get it going.
Don't worry about the seal it will be more than fine. I recommend using a pair of leather welding gloves if it all possible seeing as how you are handling a 400 degree piece of metal.

400 degrees is not THAT hot, its just hot enough to expand the hub.

BTW I used 400 degrees just to give a number. its nothing exact as far as heating a hub goes. It is however, the ideal cooking temperture for tostinos pizza bite tho.

I had a problem with that also, real tight. It went on with a Hammer, and then I bolted it in to finish the Job.

Don't forget about some nice crispy baked French Fries, or some Tater Tots.

Here is a pic of the hub after heating the tar out of it. It went on that far and sounded like it hit the end (stopped abruptly, clunk!) . Not sure what to try? Tried the long bolt method, ended up stripping the crank bolt hole had to tap it and will need a new bolt now. Wow this sucks, any ideas? I may try the oven idea..

You guys are making me hungry!
I thought you couldn't hammer the crank because of the bearings being fragile? I did pound it on initially, got it about 3/4's of the way on.

Look in a Hub when you get a chance, it's not that deep.
