3T2571 Seal for Caterpillar Equipment

The 3T2571 is a transmission seal ring for Caterpillar equipment, including Caterpillar engine-machine applications and track-type tractors. It is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The seal is identified by the Caterpillar part number 3T-2571 and the compact catalog format 3T2571. The available product data specifies an oversize seal thickness of 0.38 mm, equivalent to 0.014 in.

Fitment

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

• Caterpillar 3306
• Caterpillar 6A
• Caterpillar 6S
• Caterpillar D6E

The listed applications include Caterpillar engine-machine equipment and Caterpillar track-type tractor equipment. Fitment should be checked against the machine model, serial number, and the seal specification required for the transmission assembly before installation.

Cross-reference numbers

3T2571 and 3T-2571 refer to the same listed part-number designation, with and without the separator. The available source data does not provide additional supplier numbers for this seal.

Specifications

The dimensional values above are the listed product dimensions. The available data does not specify the seal's internal diameter, external diameter, material, cross-section profile, or the quantity supplied. These parameters should be confirmed from the existing seal, transmission assembly documentation, or the machine parts information when the 3T2571 designation alone is insufficient.
