Sounds like you are ahead of me in skills/tools for that. I do leave machine work to qualified machine shops, including installing cam bearings, as I don't have the tools for that. You don't need to pull the engine to swap cam bearings, it just takes some work and beers.Well again I am no expert, just wrench on my own cars. I changed oil and put new oil filter just in case but it runs like crazy again.

Took me two beers to size the bearings, but they came out really smooth and nice looking after.Ĭar is on the road for a while now. Took me a while to make sure no bearing shavings go to the windage tray and pan. This works great because using nut on a thread you can control bearing location very precise.īearings 2 and 3 were too tight, so I used old cam with grooves to size them. This worked like magic, all was done very fast, again 15-20 minutes and all the bearings were in without using hammer once. Using threaded rod with washer welded on I pushed new bearings in place. I tried to use this tool to push the new ones in but it was not going that smooth so I used lathe again to make size matched pushers. It took me like 15-20 minutes to pull all the bearings out. I was using a wrench on a nut to pull each bearing out, worked great. Had to push the wedge from the front using some tube to be able to pull the last bearing mostly. I made a puller using threaded rod with big washer welded on the back and piece of aluminum with a hole as locating part the size of 1st front cam bearing. Used rubber bands to keep 4 elements together and pulled one bearing after another spreading each tool to size with sized wedge. Tool is very simple, I used lathe to make size matched pushers made of aluminum for each bearing, and cut every single one to 4 pieces so they spread out and match the bearing size after they go past the bearing. I decided that it wont stop me that easy so I made a cam bearing puller and pulled all the bearings with engine in the car.
