Great budget tool.
I was skeptical buying special use tools from Amazon, but the cost of buying brand name tools for 1, maybe 2 times use was just too much. I have pretty much overhauled my 99 Twin Cam and all the tools I bought here. All performed perfectly.

Awesome Tool! Worth every penny!
This worked! It pulled the race off with no problem. Added little heat and used an impact. It came right off! The installation tool was bent, or welded together unevenly, for some reason, but it worked as well.

I had to shave .005 thousands off of the back to fit the puller behind the bearing. I also used a thinner washer to press the new bearing on, to make sure I had enough threads. It seems well built, worked well and saved a ton of money over taking the bike to a shop. It even came with a pair of shop gloves. Great value.

Sooner or later you’re going to need this tool… it’s the only way to get the inner race of the inner primary bearing off the transmission main shaft
