NOTE
The drive side pump shaft bearing is held in place by a snap ring, Do NOT place ex-
cessive pressure on the gearbox by allowing the press to exert force on the bearing.
The pump shaft must pass thru the bearing with the force applied to the shaft and
NOT the bearing.
c)
Begin pressing pump shaft with press piston in direct contact with shaft.
d)
Just before press piston contacts drive side bearing, add a pusher (wood dowel or
metal rod) between piston and pump shaft and align pusher with pump shaft so
pusher slides thru drive side bearing with minimal resistance.
