Description
CH11686 Bushings are core transmission support components specifically engineered for Perkins engines, primarily compatible with the Perkins 400 Series (403D-15, 404D-22), 1000 Series (103-15, 104-22) engines. It is extensively utilised in compact construction machinery (e.g., micro excavators, walk-behind rollers), agricultural equipment (tea pruning machines, small seeders), portable generator sets (10-30kVA), and industrial auxiliary equipment (small diesel water pumps, air compressors), providing precise support and low-friction protection for critical engine moving components.
Core Applications
Front/Rear Crankshaft Support Protection
The CH11686 bushing is primarily installed at the crankshaft front oil seal housing or rear flywheel housing interface. Functioning as a ‘buffer connection’ between the crankshaft and fixed components, it provides stable support for high-speed crankshaft rotation (suitable for maximum speeds up to 4000 r/min), limits radial crankshaft runout (controlled within 0.05mm), and prevents seal failure or component wear caused by direct friction between the crankshaft and oil seals/housing. This ensures stable operation of the crankshaft drive system while reducing engine vibration and noise generated by crankshaft oscillation. housing, thereby ensuring stable operation of the crankshaft drive system and reducing engine vibration and noise caused by crankshaft oscillation.
Reducing Friction Losses and Extending Component Lifespan
Its inherent low-friction properties create a ‘lubricating medium layer’ between the crankshaft journals and the fixed housing's metal surfaces, lowering the sliding friction coefficient below 0.07 (compared to approximately 0.25 for direct metal-to-metal contact). This substantially reduces friction energy losses; Simultaneously, it evenly distributes radial pressure during crankshaft operation, preventing localised stress concentration that could cause shell bore indentation or wear. This extends the service life of the crankshaft, housing, and oil seals while reducing engine maintenance frequency.
Sealing Assistance and Contaminant Barrier
Tailored for the dusty and humid conditions of outdoor machinery, the CH11686 bushing and oil seal collaborate to form dual protection. Its precision clearance prevents external dust and moisture from entering the crankcase, avoiding contamination of engine oil or wear on crankshaft journals. Simultaneously, it assists in maintaining internal crankcase oil sealing, preventing oil leakage along the crankshaft end and ensuring stable oil volume within the engine lubrication system.
