MAINTENANCE/SERVICE

Traction Drive: Neutral Lock and
Steering Checks (continued)

6. Radius Arm Pivots: Check the two pivots (A)

and (C). At each pivot, torque inner nut (D) to 7
ft.lbs. (10 N

⋅m). Hold inner nut (D) with a

wrench and tighten outer nut (E) against nut
(D). Torque nut (E) to 60 to 70 ft.lbs. (80 to 90
N

⋅m).

IMPORTANT: Be sure to hold inner nut (D)

while tightening outer nut (E). Nut (D) MUST
NOT TURN.

At ball joint connection (B), torque both nuts to

60 to 70 ft.lbs. (80 to 90 N

⋅m).

7. Ground Speed Lever Position: Check that when

the steering wheel is locked, the ground speed
lever (F) is centered fore-aft in the neutral
detent on side console as shown.

To adjust:

a. Loosen bolts (G) (see photo above), allowing

bolts to slide in slots.

b. Lock the pintle arms in the neutral lock

adjustment bolts. See check 3.

c. Hold ground speed lever (F) centered fore-aft in

neutral detent.

d. Have a second person tighten bolts (G) as

follows:

- inner nut: 80 to 90 ft.lbs. (110 to 120 N

⋅m)

- outer nut: 60 to 70 ft.lbs. (80 to 90 N

⋅m)

8. Neutral Lock Structure: Check for proper

movement of support structure (J) for the
neutral lock adjustment bolts as follows:

a. Disconnect spring (P) to unload pivots.
b. Check that support structure (J) rotates freely.
c. Check that there is no fore-aft movement of

support structure (J).

d. If no adjustment is required, reconnect spring

(P).

To adjust:
a. Turn nut (K) until the washer just contacts the

plastic bushing. This pivot must allow free
rotation of the support structure.

b. Turn nut (L) until the washer contacts the front

support. Check again for free rotation of the
structure with no fore-aft movement. To lock,
hold inner nut (L) with a wrench and tighten
outer nut (M) against nut (L). Torque nut (M) to
60 to 70 ft.lbs. (80 to 90 N

⋅m).

c. Reconnect spring (P).

9. Loose Hardware: Check all hardware (not

included in the previous checks) is properly
tightened to torque specifications on ground
speed controls, control rods, pump pintle arms
and neutral start mechanisms.
