NOTE: When ordering shims, find the part number in the
parts catalog by using the thickness of shims listed in the
above table.4. Place the shim on the drive pinion, with the chamfered
side turned towards the pinion head then install the
inner bearing onto the pinion using an installer
9–8522–1165–0 and a press.
