3 For engines that use the idler gear assembly with needle roller bearings - Inspect the components for wear
and other damage and renew them if necessary. Lightly lubricate the components with clean lubricating oil
before assembly onto the hub. Fit the hub (D8) as described in step 1. Put the rear spacer (D7) in position on
the hub. Put the rear thrust washer (D6) in position on the rear spacer. Put the bearings (D5) in position on the
hub in the same position as they were before they were removed. Lightly lubricate the bore and thrust washer
faces of the gear (D4) with clean lubricating oil and put the gear in position on the bearings. Put the front spacer
(D3) in position on the hub then put the front thrust washer (D2) in position on the spacer. Put the plate (D1)
in position. The plate has TOP stamped on the front face as the holes in the plate are not equally spaced. Fit
the setscrews and tighten them to 44 Nm (33 lbf ft) 4,5 kgf m).
