homemade crank puller

ped · Post by **ped** » Sun Feb 01, 2015 11:41 am

Hi forum. here's a homemade crank puller I made from a 4 inch C clamp from Harbor Freight, 1 1/4 black pipe from Home Depot, a couple washers, a couple nuts Home Depot. Total cost about 20 bucks. You will need a welder, Harbor Freight 99 bucks.

or have someone weld it up for you.

not a welder. is long as you melt the metal you should be good.
this is not for something very important like a frame.

the screw gets tightened down. And I turn on that flap. the black clamp part.

yes it is. It's best to heat up the bearings with a heat gun little bit.

Greetings:

Very clever and useful work. Just to clarify; you heat the cases to enlarge the bearing sockets, and chill the bearings for easier insertion, right?

I freeze the crank first then slip the bearings on then freeze that. I put Hondabond on the cases then heat them with heat gun or torch. Then I hope they go together easily but when they don't I'll use this to complete the install.

Hi Whitey. that threaded rod is perfect.

Only needed to weld the two nuts together. any muffler shop can do that for you.
I went with the clamp because it had bigger threads. And looks a little stronger. But there's nothing wrong with the threaded rod. It was most likely less money and less work.
nice work

Wow what a great thread! Always great to have more tricks and designs for tools. I'm going to make a crank puller this summer for sure after seeing this thread

Hi Whitey. I see you notice. I havent decided on a setup. something for the street for sure.
