1424004 Ring-seal fit Caterpillar

1424004 is a transmission seal ring for Caterpillar articulated dump trucks, including the 725, 725C, 725C2 and 730 models. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The ring is identified in the supplied product data as a RING-SEAL and is intended for use in the transmission system of the specified Caterpillar equipment. The available fitment information identifies the machine type as an articulated dump truck and lists the compatible model designations below.

Fitment

• Caterpillar articulated dump truck
• Caterpillar 725
• Caterpillar 725C
• Caterpillar 725C2
• Caterpillar 730

The listed fitment applies to the model designations provided for part number 142-4004. The available source data does not identify a production year, serial-number range, transmission assembly position or separate machine configuration. These details should therefore be checked against the equipment identification and the part removed from the machine before installation.

Cross-reference numbers

• 142-4004
• 1424004

1424004 and 142-4004 are the two number formats associated with this ring-seal in the supplied product information. The product name also identifies the part as Caterpillar RING-SEAL. No additional equipment-manufacturer or supplier reference numbers are specified in the available data.

Specifications

The dimensional data is presented in the units supplied with the product information. The base diameter, cross-section width and cross-section thickness are stated in inches; the package or product dimension entries are stated in centimetres. The source data does not clarify whether the length, width and depth values describe the seal itself or its packaging, so they should not be used in place of the specified ring dimensions for fitment verification.

The supplied specifications identify PTFE as the material but do not provide hardness, temperature range, pressure rating, installation direction or sealing-profile details. The seal type is also not further defined beyond the RING-SEAL designation.
