rear needle bearing replacement
the bearings are only available from zzp in murika the style 2 with the open back
to remove them you will need a blind bearing puller
the slide hammer was not effective enough to remove the old shells
after snapping the plastic cage and removing all the needles the tool end was fitted and locked in then flat plate m10 all thread with many washers and a nut also applying lots of heat to the alloy casing around the shells helped get them out
the plate was not quite thick enough 🙂
old ones out
case cleaned and new bearings fitted with the rear end of the right sized socket and an extension bar hammer in till just under the surface
fit the rotors back in the case and turn them just as they go in to the new bearings
you will need to apply anaerobic red sealant to the rotor pack case flange
add a new coupler if needed 🙂
fit the snout with the same red anaerobic sealant and then thread sealant to the 2 lower bolts the protrude into the rotor case
then add 4fl oz (100ml) of the gm branded supercharger oil 🙂
fitting a replacement bypass valve
install preload tool
turn the flap so the groove in the pin fits in place
install bolts loosely make sure flap is shut and tighten the bolts
testing the bypass valve with a vacuum brake bleeder fitted to the 2nd port if it pulls a vacuum then the diaphragm is split altho the valve will still work
