19 - PRM 60
Fit drain and oil level plugs (26) with bonded washer (31) to the sides of the gearcase (2). Fit oil filling plug (48) with
bonded washer (54). Fit dipstick (28) and breather (30) with bonded washer (52). Finally adjust the gear selector lever
(44) into the required position.
9.7.6 Cone Clutch Selection
With the selector lever (44) in neutral position manually rotate the output coupling (23). The eccentricity of the cone
clutch (11) groove causes an axial shift on the selector shoe (22). The variable distance between the end of the selector
shoe (22) and the output shaft (14) vertical centre line upon rotation provides MAX & MIN axial movement of the
selector shoe (22). With no further rotation of the output coupling (23), screw the dog point grub screw (50) until contact
is made with the bottom of the selector shoe (22). Fit the nut (49) upto selector body (18),
not allowing any rotation of
the dog point grub screw (50). Unscrew the dog point grub screw (50) simultaneously with the nut (49) attached until a
0.60mm gap is achieved between the nut (49) and the selector body (18). With no further movement of the dog point
grub screw (50) tighten the nut (49) against the selector body (18) to 17 Nm (13lbft). This will give 0.60mm clearance
between the bottom of the selector shoe (22) and the dog point grub screw (50) at max cone eccentricity.
CAUTION:
This condition can only be maintained with the clutch at the top dead centre. If this is not
achieved the gear selection will be affected, creating difficulty in gear engagement or disengagement.
