c. Inspection. Inspect the cone collar for wear, out-of-round, cracks, and breaks. Check the cone collar bolts and
nuts for corrosion and damaged or stripped threads. Inspect the shims for corrosion and breaks. Use new cotter pins
when reassembling the cone collar.
d. Repair.
(1) Replace all damaged, corroded, stripped, or galled bolts and nuts.
(2) Replace the shims if they are warped, cracked, or splintered.
(3) Replace the cone collar if it is cracked, broken, or worn more than one-eighth inch out-of-round.
(4) Replace damaged, corroded, or broken grease fitting.
e. Reassembly and Installation.
(1) Install the grease fitting (10) on the cone collar (5).
(2) Assemble both halves of the cone collar (5) and install the shims (7), bolts (6), and nuts (8).
(3) Install the cone collar and check for free sliding. If the cone collar sticks, install additional shims. If the cone
collar is too loose, remove shims until the cone collar slides freely and without binding.
(4) Tighten the nuts (8) and install new cotter pins (9).
(5) Install the cone collar assembly (5) in its proper place.
(6) Install the clutch yoke (2) on the shift shaft (1) and connect it with the cone collar (5).
(7) Install the setscrew (4) and jam nut (3).
(8) Tighten the setscrew (4) and secure it with the jam nut (3).
Section XIII. TRANSMISSION
143.
Description
The heavy-duty transmission is enclosed in an oil and dusttight case (14) bolted to two cross-members of the roller
main frame. The transmission case (14) encloses the master clutch housing (42), which is bolted to the engine flywheel
housing. All transmission gears are made of machined and heat-treated alloy steel. The bevel pinion (45) is mounted on
the master clutch shaft (40) and is secured with a jam nut (44) and cotter pin. The bevel pinion (45) runs in constant mesh
with the two bevel gears (47) mounted on the forward and reverse clutch shaft (53) and controls the forward and reverse
movement of the roller. The gear shift shaft (20) is mounted on two large bearings (13 and 23) and assures proper
alinement when engaging or disengaging either clutch. The slow (16) and the fast (27) gears are mounted on the first
countershaft (8) and driven by the double speed pinion (35) on the forward and reverse clutch shaft (53). The first
countershaft (8) is enclosed in the first countershaft bearing tube
