What cam bearings were used for E303 install in 302
I'm going to replace the cam bearings before installing a new E303 cam and was wondering what the choice size bearing people used here. Would a stock size bearing fit for the new cam? I have not mic the cam bearing lobes yet , but I figured it would be set to the stock measurement for bearings so they fit the journals.
I guess I am going to have to design a tool also to knock the old ones out and install the new bearings. I was thinking about going to oriellys or autozone and tool borrowing one of their bearing insert tools. I still will need a straight bar and some type of cone to keep the bar straight as I tap in the bearings. The tools they had seemed too short to insert the 2 inner bearings.
I'm doing this without removing the crank and pistons, so it will be a very careful process to match the oil ports exactly.
One other thing about the new bearings, I read somewhere that to grind a groove on outside of the ring of the cam bearing closest to the thrust bearing for allowing oil to flow to timing chain or something like this. This might of been just a mod that I seen done in a youtube video, but seemed to be a decent idea anytime you can make better lubrication to a moving part.
Here is an example of what I explained. It would be just a surface groove for the incoming oil to enter timing chain and down to the sprocket shaft area.
