3. Apply a thin coat of anti-seize lubricant to the transmission output shaft.
4. Position the sprocket in the drive chain. Move the transmission toward the
mounting bracket while guiding the sprocket onto the output shaft.
5. Secure the transmission to the mounting bracket and lower the transmission
mount with the bolts, locknuts, and flat washers.
6. Secure the sprocket to the transmission output shaft with the retaining ring
(item 11 in Figure 34 ).
Note: If the idler arm assembly requires service; refer to Drive Chain Idler
Arm (GreensPro 1240) (page 7–13) .
7. Install the flat washer and hex nut (item 14 and 15 in Figure 34 ) on the idler
adjustment rod. Thread the nut 32 mm (1.25 inches) onto the rod.

spacer, and locknut. Do not adjust the idler adjustment rod (chain tension)
at this time.

on the idler adjustment rod.
10. Connect the transmission collar to the drive coupling (item 1 in Figure 33 )
with the bolts, flat washers, spacers, and locknuts. Tighten the locknuts to 23
to 29 N∙m (17 to 21 ft-lb) .
IMPORTANT
To prevent damage to the drive coupling, ensure that no distortion
of coupling exists after securing the transmission collar to the
coupling. If coupling distortion is evident, loosen the transmission
and/or engine and position the transmission and/or engine on frame
so that the coupling is not distorted.
