rod mounting threads are corroded, damaged, stripped, or galled.
f. Reassembly.
(1) Install the jam nuts (4) on the master clutch rod (5).
(2) Install the yokes (2) on the master clutch rod (5).
(3) Do not tighten the jam nuts (4) as the length of the master clutch rod (5) must be adjusted during
installation.
g. Installation.
(1) Connect the yoke (2) with the master clutch arm (6) and install the pin (3) and cotter pin (7).
(2) Lift up the master clutch rod (5) and see that it reaches the lever shaft arm (1). The length of the master
clutch rod can be adjusted by turning the rod (5) in or out of the yoke (2).
(8) Adjust the master clutch rod (5) so that there will be no great play in the linkage when the master clutch
lever is moved.
(4) Connect the yoke (2) with the lever shaft arm (1) and install the pin (3) and cotter-pin (7). Secure the cotter
pins (7).
(5) Tighten the jam nuts (4).

Forward and Reverse Clutches
a. General. The forward and reverse clutches are cone engaged. When the cone sleeve (8) is moved in towards the
clutch, the rollers (6) of the three clutch levers (5) travel up the contour of the cone. This action applies pressure against
the floating plate (13) which engages the clutch. When the cone sleeve (8) is moved out, pressure against the floating
plate (13) is released and the clutch becomes disengaged.
b. Adjustment.
(1) New clutches may require several adjustments until all moving parts are worn in.
