⚙️ Key Features

• Precision-machined structural and running surfaces
• Factory geometry for the specified bearing, timing or combustion assembly

• Matched to the exact engine generation and serial range
• Engine type: 12.8L inline six-cylinder turbocharged generator diesel

🔌 Function

Supports or transfers the engine's rotating and structural loads while maintaining the specified timing, bearing alignment or cylinder geometry.

⚠️ Common Signs of Failure

• Abnormal gear noise, vibration or loss of timing
• Excessive backlash, bearing movement or bore wear
• Oil, coolant or compression leakage
• Severe engine damage if the component fails in service

🛠️ Service Notes

• Inspect the gear teeth, the bearing or bushing and the shaft or hub it runs on together — a new gear on a worn shaft will be noisy and short-lived
• Check the mating gears at the same time; a chipped or pitted tooth on either side will damage the new idler
• Where the gear forms part of a timed drive, set it up to the timing marks and the procedure in the workshop manual for your engine and confirm timing before turning the engine over
• Measure backlash and endfloat by the method in the manual rather than judging them by feel, and fit any thrust washer or plate in its original order and direction
• Oil the bearing surfaces and teeth on assembly and turn the drive over by hand to check it runs free before the covers go back on
