ALTERNATOR 7R2440 - Caterpillar

Typical Example1. Put alignment marks on the differential case halves.
There is spring force against the differential case half. When bolts (2) are removed, the spring force will be released. To prevent possible personal injury, removal of the case half should be performed in a press in order to retain the case half.
2. Put the differential in a press, and remove bolts (2). Slowly release the spring compression.3. Remove the differential case half. 4. Remove side gear (8), spacer block (9), retainer (10), spring (11) and hold out ring and clutch assembly (12). 5. Remove spider cam assembly (6), hold out ring and clutch assembly (7), spring (13), retainer (4), and side gear (5).Assemble Differential (NoSPIN)
Personal injury can result from being struck by parts propelled by a released spring force.Make sure to wear all necessary protective equipment.Follow the recommended procedure and use all recommended tooling to release the spring force.
1. Put one of the case halves in a press.2. Install side gear (5), retainer (4), spring (13), hold out ring and clutch assembly (7) and spider cam assembly (6). 3. Install hold out ring and clutch assembly (12), spring (11), retainer (10), spacer block (9) and side gear (8).
Typical Example4. Install case half (3). Use press to compress the springs in the differential.
Typical Example
A new differential group or a new case assembly will be equipped with four bolts and washers that are used for shipping, assembly and storage purposes only. Remove and discard these four bolts and washers after the bevel gear has been installed. These four bolts and washers should not be used for final assembly.
5. Install bolts (2) that hold the differential case halves together.End By:a. install differential and pinion assemblies
