-
7] and spur gear retainer nut [7
-

Torque to 25 ft/lbs.
45.
Hold front vertical shaft [7
-
3] in the direction it will be turning (slight load) with spline wrench on the rear
vertical shaft [7
-
4] (slight load) in the opposite direction. Install rear spur gear [7
-
5] turning until it drops on
the vertical shaft [7
-
4].
46.
Install tab washer [7
-
7] and spur gear retainer nut [7
-
6]. Torque to 150 ft/lbs, use red loctite.
47.
Use a
1/4”
copper rod to seat front spur gear. Remove rod, check rear spur gear for
contact with front spur gear, with slight pressure on front and rear shafts. Readjust rear
spur gear if needed.
48.
Install tab washer [7
-
7], and spur gear retaining nut [7
-
6], torque to 150 ft/lbs, use red
loctite Then use
1/4”
copper rod to seat rear spur gear to front spur gear.
Note:
If all gears are not in full contact, turn front spur gear 1
-
tooth on spline and start se-
quence over. When all gears are in full contact bend tabs on spur gear nuts. With slight
pressure on front vertical shaft (RH) take your hand and feel no movement! Release
vertical shaft pressure and rear spur will have slight free play.
