    NOTE

    Insert a pin through the hole in the full load stop bolt to prevent the bolt from turning while removing and installing the nut (2) and collar (3).

    Remove the bolts securing the governor to the fuel injection pump housing and slide the governor housing away from the fuel injection pump housing.

    Governor Weight Removal

    Separate the governor housing from the fuel in-jection pump housing as outlined in the covering topic.

    T 41 9 21

    PREPARING TO REMOVE GOVERNOR WEIGHT o Remove I-Bolt. 2-Pin. 3-Thrust bearing. 4-Bumper spring. 5-Seat.

    NOTE The bumper spring (4) is installed with the con-cave face toward the seat (5). This arrangement permits the outside edge of the spring to contact the seat (5).

    WEIGHT REMOVAL

    o Remove 6-Weight assembly. 7-Snap ring.

    GOVERNOR DISASSEMBLY

    1. Remove the seat behind the spring (5).

    2. Remove the bolts securing the cover assembly (6) to the governor housing and remove the cover assembly (6), control shaft assembly (9) and the governor shaft assembly (IO).

    3. The gasket between the cover assembly (6) and the governor housing should be inspected, and replaced if damaged.

    FRONT IDLER AND RECOIL SPRING

    Group 100.1

    PageS

    REMOVING RECOIL SPRING

    8. Install in the reverse order of removaL

    9. After recoil spring stops (6) have been installed, loosen recoil spring bolt nut (2) releasing the recoil spring tension against the stops, continue turning nut (2) until the end of the nut extends 1/16/1 beyond the end of the recoil spring bolt. Install bolt and washer (5) to lock nut (2) in place.

    T85188

    POSITIONING NUT 2-Recoil spring bolt nut. 5-Locking bolt and washer.

    A-Dimension to be obtained.

    Removal and Installation (Hydraulic Type)

    NOTE

    On machines equipped with the hydraulic track adjusting mechanism, the recoil spring can be removed without separating the track providing the recoil spring bolt is not broken.

    WARNING

    Be certain the hydraulic pressure in the track adjusting mechanism is completely relieved and the cylinder can be moved to the rear into the recoil spring front pilot before attempting to separate the track or remove the track adjusting mechanism. On machines that have badly worn track. it is possible for the hydraulic track ad-juster to be adjusted forward to the limits of its travel and the stop will be against the stop on the track roller frame. The hydraulic cylinder

    could have high oil pressu: a in it even though the track is loose enough to remove the master pin without relieving the hydraulic track adjust-ing pressure.

    T85177 ,

    REMOVING GUARDS I-Guards.

    1. Install drawbar pin (4) or hardwood block be-tween the sprocket and the track, and back the machine slightly to compress the recoil spring. When all the tension is removed from recoil spring stops (6), loosen locking bolt and washer (5), and screw recoil spring bolt nut (2) tight against rear pilot (3). Remove the drawbar pin or hardwood block.

    REMOVING TENSION FROM RECOIL SPRING STOPS 2-Recoil spring bolt nut. 3-Recoil spring rear pilot.

    4-Drawbar pin. 5-Locking bolt and washer.

    2. Separate the track and lay it out flat. See the topic SEPARATING TRACK.

    WARNING

    See the topic SEPARATING TRACK for correct procedure on releasing pressure in the hydrau-lic track adjuster cylinder.

    3. Remove bolts (7) and separate the cylinder from idler recoil rod (10). Move cylinder (9) to the rear as far as possible into front pilot (8). Move the idler rod (10) to the front as far as possible.

    4. Attach a hoist to and remove the recoil spring assembly as shown.
