1425868 Seal GP Ring for Caterpillar Equipment

The 1425868 Seal GP Ring is a crankshaft seal assembly used on Caterpillar equipment. It is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The seal is intended for dry crankshaft applications and is installed around a high-speed rotating shaft. Its construction includes a main lip seal for retaining engine oil, a dust lip seal for limiting the entry of external contaminants, and a wear sleeve that provides the sealing surface for the lip seal.

The component is supplied as a seal group ring assembly. The wear sleeve is a replaceable part of the assembly and is positioned to protect the crankshaft sealing area from wear. The seal is used in applications where the shaft may operate at high rotational speed, elevated temperature, and with axial movement.

Fitment

• Equipment manufacturer: Caterpillar
• Application: crankshaft sealing system
• Application type: dry crankshaft seal arrangement

The supplied product data identifies Caterpillar equipment as the applicable equipment brand but does not provide a specific machine model, engine model, or machine series. Compatibility should therefore be confirmed by the equipment part number before installation.

Cross-reference numbers

• 1425868
• 142-5868

Part number 1425868 is also written in the hyphenated format 142-5868. Both references identify the seal group ring listed in the supplied product data.

Specifications

The main lip provides the oil-sealing function at the rotating crankshaft surface. The dust lip forms an additional barrier against external contamination. The wear sleeve supplies a dedicated contact surface for the sealing lips and can be replaced when the sealing area has reached the end of its service condition.

Crankshaft seals of this type are used with engine crankshafts and other high-speed rotating applications, including water pump applications where the specified seal arrangement is required. The supplied product information specifies replacement of the complete crankshaft seal assembly rather than servicing the sealing elements separately.
