PROBLEM

Show/hide table

The 276-6045 Cable As may have been improperly routed and improperly clipped on certain D7R Series II Tractors. This can cause the cable assembly to interfere with the 281-3179 Bracket at the fuse box location. This interference may result in early hour failure of the 276-6045 Cable As. Symptoms of a failed alternator cable may include arcing of the cable, issues with starting the machine, and issues charging the battery.

PRIORITY - PRODUCT IMPROVEMENT PROGRAM FOR INSPECTING AND POTENTIALLY REPLACING ALTERNATOR CABLES ON CERTAIN D7R II TRACK-TYPE TRACTORS

MODELS INVOLVED - D7R II Track-Type Tractors

Dear Caterpillar Product Owner:

The alternator cable needs to be inspected and potentially reworked on the products listed below. The existing cable routing may result in interference between the alternator cable and a bracket at the fuse box location. This interference may result in early hour failure of the alternator cable. Symptoms of a failed alternator cable may include arcing of the cable, issues with starting the machine, and issues charging the battery. You will not be charged for the service performed.

Contact your local Caterpillar dealer immediately to schedule this service. The dealer will advise you of the time required to complete this service.

Please refer the dealer to their Service Letter dated 20Jul2007 when scheduling this service.

We regret the inconvenience this may cause you, but urge you to have this service performed as soon as possible to prevent unscheduled downtime.

Rework Procedure

Show/hide table

1) Open the battery box cover and the fuse panel cover on the left fender. See Image 1.1.1.

Image1.1.1

2) Inspect 276-6045 Cable As (1) for interference with 281-3179 Bracket (2) at the bottom front side (4). Due to the location of this interference, you must reach down the back side of bracket (2) in order to determine if cable assembly (1) is interfering with bracket (2). The distance between the cable assembly (1) and the bottom front side of the bracket (4) should be no less than 12 mm. See Image 1.2.1 and Image 1.2.2.

Image1.2.1

Image1.2.2

3) If cable assembly (1) is not interfering with the bracket (2) and there is adequate clearance, then no further action is required. If there is interference, then proceed to the next step.

4) If cable assembly (1) is interfering with bracket (2) but there is no wear on cable assembly (1), then adjust the location of cable assembly (1) by loosening the two 5P-4295 Clips (3) and moving cable assembly (1) toward the front of the machine in order to provide the required clearance. Torque the bolts for clips (3) to 55 ? 10 N?m (40 ? 7 lb ft). See Image 1.4.1.

Image1.4.1

5) If cable assembly (1) is interfering with bracket (2) and there is wear on cable assembly (1), then replace existing 276-6045 Cable As. with a new 314-4218 Cable As. The new 314-4218 Cable As. replaces the 276-6045 Cable As. The existing clips that were referred to in Step 4 will be used to secure the new 314-4218 Cable As.

Reference: For the routing and clipping locations of cable assembly (1), refer to 271-6423 Engine Wiring Gp.
