9N6611 Fan Drive Pulley for Caterpillar Equipment

The 9N6611 fan drive pulley is a belt-driven component used in the fan drive system of Caterpillar equipment. It transfers rotation from the belt to the cooling fan and is used on tracked bulldozers, Challenger tractors, wheel bulldozers, wheel loaders, and earthwork compactors listed below. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

Fitment

The pulley is listed for the following Caterpillar equipment models and machine series:

• Tracked bulldozers: D6R, D7H, D7R, 56, 56H, 57, 57H, 6, 6A, 6S, 6SU, 7, 7A, 7S, 7S LGP, 7SU, 7U, D6H.
• Challenger tractors: 65, 65B, 65C, 65D.
• Wheel bulldozers: 814B, 814F.
• Wheel loaders: 966D, 966E, 966F, 966F II, 970F.
• Earthwork compactors: 815B, 815F, 816B, 816F.

Fitment should be verified by comparing the equipment model and the part number before installation. The listed applications cover several Caterpillar machine types and series; the machine model designation should be matched with the existing fan drive assembly.

Cross-reference numbers

• 9N-6611 — Caterpillar part-number format shown for the fan drive pulley.
