description

This matched belt set is pre-sorted for identical length, tension and elasticity. It adopts high-temperature resistant rubber and high-strength tensile cords, with tooth design for better bending performance under continuous heat and shock of high-power engine. Uneven wear, tooth crack and delamination on one belt will break the balance, trigger vibration and slip, reduce fan speed and cause engine overheat. If one belt breaks, the other will fail rapidly.

Part No.:6N-6651
Type: Matched toothed V-belt set
Material: Heat-resistant rubber, high-strength tensile cord
Structure: Inner toothed design, pre-matched pair
Working Condition: High temperature, alternating impact and long continuous operation for high-power engine
Matching System: Cooling fan drive assembly

Application Scenarios

Fits Caterpillar C15, 3408 diesel engines, for overhaul of cooling fan drive circuit on large wheel loaders, mining generator sets and oilfield power units.

FAQ 

Q：Can only the damaged belt be replaced while the other one looks good?
A：No. They are pre-matched pair. Mixed old and new belts lead to uneven load and early failure.

Q：Can this set replace single 4L-4648 belt directly?
A：Not allowed. Load design differs, single belt cannot bear the load and slips easily.

Q：Why do two belts vibrate differently during operation?
A：Tension mismatch or worn pulley groove, re-adjust tension or inspect pulley.

Q：Can fuel-stained belts be reused after wiping?
A：Oil penetrates rubber and reduces strength, full set replacement is required.
