Photos of the alternative crank bearing I use for high revving engines, the triple front bearing set up gives a free spinning crank with no preload
but plenty of thrust capability, the single track front bearing helps keep the timing gears in mesh. At the rear the separate centre sleeve of the
bearing can be pressed on the crank before fitting into the c/case which makes assembly or removal much easier (although I have never had
to replace one) or use a standard MRJ 1 1/4 preferably with a brass cage.
