[QUOTE="oexing, post: 131720, member: 1493"] Biggest problem was excessive wear in tunnels so no stock rocker bearing would be available to suit. So homemade bearings were to be made and I came up with the two part bearings for easy milling the slot for the rocker to size for each individual rocker after surface grinding them to get the lot into acceptable shape. There were a few things I did not like with the whole rocker bearing and oil ways over heads , no wish to weaken rockers for these feed bolt nuts anyway. So I ended with all-o-ring seals in all joints along the oil lines . I had only very knackered collection of spares in the boxes so instead of spending a lot of money on new spares with details I did not really love it was another job in my workshop - ahhmm, sort of my living room really. Securing these grub screws is in my head, thanks, a bit of mild Loctite was used here, but a little punch in the thread end would do as well. Don´t think it is as critical as in that design with split bearings because the grub presses on o-ring material, basically quite shakeproof in similar cases.
