07000-73028 O-Ring for Komatsu Equipment

07000-73028 is an O-ring used in Komatsu equipment, including Komatsu trucks and engines. The part is new, aftermarket, and manufactured by CTP (Costex Tractor Parts).

Fitment

The available application data identifies this O-ring for the following Komatsu equipment and engine series:

• Komatsu HD325-6 dump truck
• Komatsu HM400-1 dump truck
• Komatsu 330M equipment
• Komatsu 6D125E-2A engine series

The application reference for the part is listed as “O-RING, FOR HD325-6 / HM400-1 (A2110)”. The O-ring is intended for use in the sealing system of the applicable Komatsu assembly. Exact installation position and the mating component are not specified in the available product data, so compatibility should be checked against the equipment serial number and the removed part before installation.

The listed fitment includes both complete Komatsu machines and the 6D125E-2A engine series. The presence of a compatible machine model does not by itself identify every location where the seal may be installed; the part number remains the primary identification reference for selecting the replacement seal.

Cross-reference numbers

The available data lists 07000-73028 as both the Komatsu equipment manufacturer reference and the CTP part number. No additional supplier numbers are specified. The designation A2110 is included in the application description and is not provided as a separate replacement part number.

When comparing this seal with a part removed from the machine, the part number should be matched with the equipment documentation, component identification, or service parts list. Model names alone may cover multiple configurations, and the supplied data does not include serial-number ranges or a separate list of superseded numbers.

Specifications

The dimensions and weight are the values provided for the listed part. The available data does not specify the elastomer material, hardness, inner diameter, cross-section diameter, temperature range, pressure rating, thread specification, or installation lubricant. These parameters should not be substituted with values from another O-ring size or application.

The package contents are limited to the 07000-73028 O-ring unless a different package composition is stated separately. No additional seals, retaining rings, fasteners, or installation components are identified in the supplied product information.
