Slotted Cam Trick ????


Sorry, the cam bearings were tight, so I used an old cam with slots cut in it to shave the cam bearings to size. I tried this earlier, but did not clean up the burrs after slotting the cam journals ans it took too much off the bearings, so I cleaned up the slots, de-burring them and this time it did a good job sizing the cam bearings.



I'm not a fan of the slotted cam trick. I like to put some green scotch brite in a slotted mandrel and clean up the bores really good with a die grinder. Then I clean off the leading outside edge of the cam bearings so they start in the cam bores without pulling material and I also take a razor blade and de-bur both inside edges of the cam bearings as I've seen a little bit of an edge that can cause the cam to be tight. I've had fair to good luck doing this. Sometimes though, I've had to use the scotch brite on the inside of the bearings. Not my preferred method, but the cam really does need to turn freely.
