Blade Brake Band Adjustment

NOTE: The length of the actuator rod is adjusted by disconnecting the bottom clevis and shortening or lengthening accordingly. The standard pre-set length of the actuator rod is set at the factory at 8-1/4 in. (209 mm).

2.After adjustments are complete, check blade brake action as described in CHECKING/SER- VICING the Blade Brake Action in this section. If blades do not stop within five (5) seconds, check the following:

a.Recheck 1/8 in. (3 mm) gap between stop block and chassis.

b.Make sure clutch and brake linkage are working freely (no binding).

c.Check the brake band lining.

d.Check the brake drum on the pulley. If excessive wear is present, it will be neces- sary to replace worn parts.

Transmission Control

IMPORTANT: The proper adjustment of the transmission control stops is essential for efficient operation and life of the transmission. These stops are properly adjusted at the factory and should only require readjustment if the transmission or related control linkage is removed or changed.

NOTE: It would not be unusual for a new machine, after initial 5 or 10 hours of operation, to begin to not travel straight (this is due to the break-in of the transmissions). In this case, proceed to Straight Ground Travel Adjustment - Step 4.

IMPORTANT: The following adjustment procedures are sequential. Check and adjust each function in the order given.

Set Forward Travel Limit (Stop) - Step 1

1.Move the Forward Speed Control (FSC) lever to the most FORWARD position.

2.Check clearance of the RH and LH steering le- ver actuator arms with the frame and adjust for- ward stop bolt so each lever clears the frame by at least 1/16 in. (1.6 mm). Clearance of the arm to the frame should be checked while ap- plying pressure back on the arm to remove any slack in the linkage.

3.Tighten the jam nut on the forward travel stop adjusting bolt.
