AXLE AR-FIXED 3705247 - Caterpillar

1. Remove two bolts (1), washers, clip (2) and guard (3). 2. Cut lock-wire and disconnect wire harness (4) from sensor (5).3. Remove bolts (6), washers (7), grommets (9) and spacers (8).4. Slide housing (11) off of the shaft that drives sped sensor gear.5. Remove spacer (10) from the transfer gear case.The following steps are for the installation of the transmission electronic speed sensor:6. Put spacer (10) and housing (11) in position on the transfer gear case with the spline on the shaft engaged with the spline on the speed sensor.7. Put washers (7), grommets (9) and spacers (8) in position on bolts (6). Install bolts (6) that hold speed sensor.8. Connect wire harness (4) to sensor (5) and lock in position with lock-wire.9. Position spacer (8), grommet (9), guard (3) and clip (2). Install washers and bolts (1).Disassemble Transmission Electronic Speed Sensor
Start By:a. remove transmission electronic speed sensor 1. Remove sensor (2) from housing (1).2. Remove the O-ring seal from sensor (2). 3. Turn gear (3) so that four bolts (4) can be seen through the openings in the gear.4. Remove four bolts (4) that hold the retainer to housing (1). Remove gear (3) and the retainer from the housing. 5. Remove spiral ring (6) that holds bearing (5) to the hub of gear (3). 6. Remove bearing (5) from the gear hub with tooling (A).7. Remove retainer (7) from gear (3).Assemble Transmission Electronic Speed Sensor
1. Put retainer (1) in position on gear (3) as shown.2. Put gear (3) and retainer (1) in a press, and press bearing (2) into position against the shoulder of the gear hub with tool (A). 3. Install spiral ring (4) in groove (5) to hold the bearing in position and the gear hub. 4. Put the gear in position in housing (6). Rotate the retainer so that the edge (8) is over hole (7) in the housing. Install the four bolts that hold the retainer to the housing. 5. Put O-ring seal (9) on sensor (10), and install the sensor in housing (6). Tighten the sensor to a torque of 20 to 27 N m (15 to 20 lb ft).6. With the gear in a horizontal position as shown, check the gap between the gear and sensor. The gap must be between 0.64 1.14 mm (.025 .045 in).End By:a. install transmission electronic speed sensor
