- This is the distance piece that betweens the cams and the cambox back bearing. It ensures the back bearing inner cage and rollers are sititng centrally in the outer bearing (which is located in the cambox rear cover. Note this distance piece is 55 thou thick, which I find to normally be correct, but you should check yourself that this thickness locates the bearing in the correct position, as this can sometimes vary as there were many slight variations over the years. To help with this, place thick high melting point grease in the outer cage of the back bearing, then trial fit the back cover, you can then see from the marks in the grease if the inner race is in the correct position. This distance piece is also supplied as part of the camshaft bevel shim set.

4 x 1/4"Clevis Pins, 5.8" length. Note these clevis pins are not the type I sell for gearbox linkages or checkspring clevis's, which require a slightly longer clevis pin, those are shown in the gearbox/fork section. In case you need to check, the distance from shoulder to the start of the split link hole on these is 0.446" and they use 1/16" split pins (also listed in this section)
