Description
Heavy-Duty Crankshaft Bushing (.010″ / 0.25mm Undersize) for Caterpillar 3013C Engines
Precision-engineered undersize crankshaft sleeve bearing designed specifically for remanufactured or turned crankshafts in Caterpillar 3013C industrial diesel engines. Essential for rebuilding engines following journal machining to restore factory oil clearances.
Key Technical Features:
- Precision Undersize Fit: Sized at 0.25 mm (.010″) undersize to match ground crankshaft journals and maintain hydro-dynamic oil film thickness.
- High-Fatigue Alloy: Multi-layer bearing construction engineered to withstand peak combustion pressures and continuous rotational stress.
- Optimized Lubrication: Accurate oil groove profiling ensures continuous lubricant delivery across the bearing surface to prevent galling.
Service & Rebuild Notes:
This component is required when the crankshaft journal has been machined .010″ (0.25mm) under standard specification. Always measure journal diameter with a calibrated micrometer and verify oil clearances using Plastigauge before final torquing.
