(3) Remove the cotter pin (7) and pin (3) attaching the yoke (2) to the gear shifting arm (6).
(4) Disconnect the yoke (2) from the gear shifting arm (6) and remove the gear shifting rod (5).
c. Disassembly.
(1) Loosen the jam nut (4) and unscrew the yoke (2) from the gear shifting rod (5).
(2) Unscrew the jam nuts (4) from the gear shifting rod (5).
d. Inspection. Inspect the jam nuts and yokes for cracks, excessive wear, and damaged or stripped threads. Check
the yoke pins for excessive wear, corrosion, and pitting. Inspect the threads on the gear shifting rod for corrosion,
damage, and wear. Use new cotter pins when reassembling the linkage.
e. Reassembly.
(1) Install the jam nuts (4) on the gear shifting rod (5).
(2) Install the yokes (2) on the gear shifting rod (5).
(3) Do not tighten the jam nuts (4), as the length of the rod must be adjusted during installation.
f. Installation.
(1) Connect the yoke (2) with the gear shaft arm (1) and install the pin (3) and cotter pin (7). Secure the cotter
pin (7).
(2) Lift up the gear shifting rod (5) and see that it reaches the gear shifting arm (6). The length of the rod (5)
can be adjusted by turning the yoke (2) clockwise or counterclockwise.
(3) Connect the yoke (2) with the gear shifting arm (6) and install the pin (3) and cotter pin (7). Secure the
cotter pin (7).
Section XIV. BRAKING SYSTEM
146.
Description (fig. 63)
The road roller brake is of the internal expanding type and is located within the second countershaft. The brake is
operated by dual brake pedals (5), located on the right and left side of the driver's platform. The brake is used for parking
and for braking the road roller when operating on steep grades. A brake ratchet (3) locks the brake in applied position.
The brake pedals (5) are connected with the brake control shaft (18) and brake adjusting rod (25). The adjusting rod (25)
is connected with the brake arm (26), which operates the brake.
