D3C, D4C AND D5C SERIES II TRACTORS POWER TRAIN Caterpillar


Transmission

Usage:

Separation & Connection Of Engine And Transmission

Start By:

a. remove engine and transmission (see 3046 Engine Supplement SENR5343)

1. Attach tool (A) to transmission eyebolts as shown.

NOTE: Two eyebolts are attached to the transmission at assembly.

2. Remove twelve bolts and washers (1) that hold the transmission case (2) to the flywheel housing. Carefully remove the transmission case (2) from the flywheel housing. Weight of the transmission is 295 kg (650 lb).

3. Remove O-ring seal (3) from the front of the transmission case (2). Check for wear or damage.

NOTE: For installation, make sure the teeth on torque converter engage the teeth on the flywheel properly. Insure that there is no damage to O-ring seal (3).

4. Install twelve bolts and washers (1) that secure transmission case (2) to the flywheel housing. Tighten bolts (1) to a torque of 28 ± 7 N*m (21 ± 5 lb ft).

End By:

a. install engine and transmission (see 3046 Engine Supplement SENR5343)

Transmission Control Linkage

Start By:

a. remove cab (See D3C, D4C, D5C Machine Systems SENR5341)

1. Remove clip (1) holding cable assembly (2) and cable assembly (3) in place. Cable assembly (2) controls speed and cable assembly (3) control direction.

2. Remove ten bolts and washers (4) and remove cover (5).

3. Remove cotter and pin (6) from each cable assembly.

4. Mark location of rod ends (7) on each cable assembly and loosen nut (8) and remove rod end (7) on each cable assembly.

5. Remove nut and washer (9) from each cable assembly and pull cable assembly (2) and (3) out of the transmission control housing.

6. Remove two bolts and washers (10) from each cable assembly and remove cable assembly (2) and (3) from the machine.

NOTE: The following procedure should be used to install the transmission control linkage.

7. Check seals (not shown) for wear or damage and install two bolts on each cable assembly that holds the cable assembly to the transmission.

8. Install cable assembly (2) and (3) into transmission control housing with nut and washer (9). Tighten nut to a torque of 38 ± 7 N*m (28 ± 5 lb ft).

9. Install rod ends (7) and tighten nut (8) on each cable assembly. Tighten nut to a torque of 8 ± 3 N*m (6 ± 2 lb ft).

10. Install cotter pin (6) on each cable assembly.

11. Clean surface of cover (5) and mating surface on transmission control housing and apply 7M7260 Liquid Gasket to cover (5) and install cover (5) using bolts (4).

Install clip (1) that holds cable assembly (2) and (3) in place.

NOTE: It may be necessary in some applications to adjust one or both of the cables if replacement was necessary. For the proper adjustment procedure for these cables see D3C, D4C, D5C System Operation Test And Adjust.

End By:

a. install cab (See D3C, D4C, D5C Machine Systems SENR5341)
