Camshaft Bearing Puller

I finally decided to make a bearing puller to remove camshaft bearings from OS four strokes. These can be, at times, very hard to get out by heating the crankcase. This tool lets me pull them without any issues. Slip the tool in and crank it out with a wrench.

    Since posting this puller I’ve had many inquiries. Making these on my manual machine didn’t work out so well. Having a just a few made in a shop didn’t didn’t make sense. I will be revisiting the puller in a month or so. Please check back.

    Hi Greg,

    I too would love to get a hold of at least one of these tools, maybe two. What is the latest on the availability and pricing? Thanks, James.
