While waiting on my parts I started with the cam and gear and clearance for the 30mm Schadek oil pump (T1)
Shortened the cam bolts for extra clearance : 1) 0.020 off the face of the cam bolt heads 2) Trimmed the rear of the cam bolts about flush with back of cam 3) Opened the oil pump outlet to match pump outlet 4) Hone cam thrust bearing for 0.002 end play 5) Cam spins freely on distributor side case half I used a 3 sided hand scraper to scrape/carve the aluminum in the hole to the line and blended the rest back down into the hole. EZ small bits removed and little chance of messing up the pump saddle with a power tool Also keeps the aluminum dust down till the final hone with a pencil wrapped with 600 https://www.youtube.com/watch?v=iX5ODEERDkg  |
