4N8221 is a cogged V-belt used in Caterpillar engine and machine equipment, including Caterpillar 3408, 3408C, 3408E, and 589 models. It is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The part belongs to the engine belt category and is identified in the supplied application data for Caterpillar engines, machines, and pipelayer equipment. The belt is listed for use with the equipment models shown below; the exact installation position and belt-drive configuration should be verified against the machine serial number and the removed part before installation.

Fitment

• Caterpillar 3408
• Caterpillar 3408C
• Caterpillar 3408E
• Caterpillar 589 pipelayer

The listed applications include Caterpillar engine and machine equipment. Model 589 is identified in the supplied data as pipelayer equipment. The 3408, 3408C, and 3408E designations identify Caterpillar engine or equipment applications associated with this belt.

Cross-reference numbers

4N8221 and 4N-8221 are two written formats of the same identification number. The number should be matched with the equipment parts documentation and the belt removed from the machine before ordering or installation.

Specifications

The supplied catalog data lists the dimensions as length 7.5 cm, width 3 cm, and depth 20 cm. These values are reproduced as provided and should be checked against the physical belt and the applicable Caterpillar parts documentation, particularly where belt-drive dimensions or machine configuration vary by model.

No additional information is provided for the belt material, number of grooves or teeth, pitch, cross-section designation, pulley arrangement, installation position, or package contents. These parameters are therefore not specified here.
