Assemble Forward-Reverse Controls
| NOTICE |
|---|
Do not damage the housing when bearings (1) are installed. Put a support in the area of the bearings so the housing will not be broken when the bearings are installed. When the bearings are installed, push on the end of the bearing that has identification. |
1. Use tooling (A) to install bearings (1) in the housing as shown.
NOTE: Levers (2) and (3) and the upper shaft are for direction control. Levers (5) and (6) and the lower shaft are for the governor control.

3. Install the four keys in the shafts. Put levers (2), (3), (5) and (6) in position over the keys. Put levers (3) and (5) in a position to stop end play of the shafts, but still let the shafts turn freely. Tighten the bolts in the levers to hold the levers tightly on the shafts.
| NOTICE |
|---|
When bearings (7) are installed in lever (8), push on the end of the bearing that has identification. |
4. Use tooling (A) to install bearings (7) in lever (8).
5. Put discs (9) and yoke (10) in position on lever (8) as shown. Install shaft (11) through the yoke, discs and lever, and install collar (12) on the shaft with the gap in the collar in alignment with the hole in the shaft.

21. Install cover (35) on the top of the console.
22. Check and adjust the force needed to pull safety lever (25) over center as follows:
a. Move direction control rod (22) to the park position.
b. Use two 3/8"-16 NC nuts and 3/8 in. washers to fasten tool (C) to safety lever (25) as shown.
c. Use tool (C) to measure the force needed to pull the safety lever over center. The force must be 40 ± 5 N (9 ± 1.1 lb.).
d. Go to Step 23 if the force is correct. If the force is not correct, remove air duct (34).
e. Remove spring (33), and disconnect rod end (27) from the safety lever. Loosen the locknut, and turn the rod end to change the force needed to pull the safety lever over center. One half turn of rod end (27) will change the force approximately 22 N (5 lb.). After the adjustment is made, tighten the locknut on rod end (27), connect the rod end to the safety lever, and install spring (33). Check the force again, and when the force is correct install air duct (34).
23. Put horn wires (36) through the hole in the console.
