GEARBOX ASSEMBLY

1. It is assumed that all bearings, oil seals, studs, oil jets, and dowels are already fitted into casing. (see page 5).

2. Slide the rearmost tophat bush (31) into place in the maincase, then slide it rearwards as far as it will go. Push the other tophat

bush into place in the maincase. Press the bearing into the reverse idler gear (95), slide the sleeve into the bearing and

position the gear between the tophat bushes with the chamfer facing aft. Apply threadlocking adhesive to the retaining bolt and

tighten into place.

3. Assemble and lubricate the oil pump (113). Slide on the pump drive gear (142) and secure with circlip (127). Fit the pump in

place in the maincase and secure with screw (122).

4. Slide the crank spindle (108) into it’s bearings (9), slide on the washer (135) and fit the selector lever (112) to the crank spindle

using roll pin (33). Assemble spherical rod end pair #1 (101 & 111) and adjust to centre distance 1.75” and lock with nut (54).

Attach one rod end to the clevis (102) using screw (66) and nut (51). Push the clevis into the bore in the maincase, then add

the washers (130), spring (120), spacer (19), screw (65), and plug (78) from the outside of the maincase. Attach the lower rod

end to the crank (108) using screw (61) and washer (131).

5. Press the bearing (10) into the ratchet arm (110) bore. Sub-assemble the pawls (109) and spring (137). Fit the pawls into the

ratchet arm (110), and secure with screws (70) and nuts (51). Assemble spherical rod end pair #2 (101 & 111) and adjust to

centre distance 2.00” (with rod end axes at 90°) & lock with nut (54). Secure one of the rod ends to the ratchet arm using

screw (61). Fit the tophat spacer (104) into the maincase. At this point it is useful to wedge the pawls in their fully disengaged

position by inserting a piece of sheet metal (approx 1.25” wide) between them,

adjacent to the spring. Hold the ratchet arm in position in the maincase, then fit

the spindle (103) and secure with screw (67). Attach the lower rod end to the

crank spindle (108) using screw (61) and washer (131). Insert the barrel driver

into the maincase, through the ratchet arm (take care not to trap the pawls) and

secure into the bearing with nut (40). Add the bearing retaining plate (49) and

screws (45). Remove the sheet metal tool from between the pawls to allow them

to engage the barrel driver.

6. It is important that the backlash between the barrel driver and the pawls be equal

in both upshift and downshift directions. Ensure that the barrel (99) and barrel

driver (100) ‘D’ drives are indexed similarly, then temporarily fit the barrel and

bearing carrier (71) onto the maincase. Restrain the barrel from rotating by fitting

a temporary dowel in place of the detent spring and lightly screwing the detent

cap down onto it. Measure the movement of the selector lever (fig. 7) in both
