[QUOTE="greg brillus, post: 178858, member: 597"] Bearing and tunnel are 1.350" diameter less a half a thou here or there.......they should be a light drive fit into the head.......be doubly sure the rocker pins are not slightly overhanging the sides of the bush as the pin will gouge a groove into the head........heating the head somewhat will help, but I generally install them cold with a light coating of oil in the tunnel bore........a soft hammer and tap the rocker works ok........keep the adjuster end of the rocker downward as the fork passes over the valve collar to sit on top of it.......a light coat of molly grease on the fork faces is good practice.......removal is best with a slide hammer using a piece of 5/16" rod with a right angle bend in it hooked through the tappet adjuster bore.
