CAT 087-1404 RETAINER

CAT 087-1404 (0871404) is a Caterpillar original equipment manufacturer (OEM) elastic retainer ring for construction machinery. It is compatible with 259D3/279D3 skid steer loaders and 906H/907H mini excavators, used at the hinge points of the working device. It works in conjunction with 087-0987 bearings, 087-0328 bushings, and 086-9971 dust covers to achieve axial positioning of the bearings, prevent movement, and ensure stable operation of the hinged joint.

Core Parameters and Information

Item Details
Part Model: CAT 087-1404 (0871404) Elastic Retaining Ring (Fixer)

Type: Elastic retaining ring for articulation points in engineering machinery (shaft/bore, depending on installation position)

Material: 65Mn spring steel, surface anodized

Key Dimensions: Fitting shaft/bore diameter 60mm, thickness 2mm, opening width 5mm

Compatible Models: CAT 259D3/279D3 skid steer loaders, 906H/907H mini excavators

Matching Relationship: Compatible with 087-0987 bearings, 087-0328 bushings, and 086-9971 dust covers for axial positioning of articulation point assemblies

Suitable Applications:
Suitable parts: Articulation points of the boom and frame, connecting rod and boom, etc., in skid steer loaders and mini excavators; suitable for frequent load changes and vibration conditions.

Application Scenarios: Suitable for outdoor operations such as excavation and loading. Prevents axial movement of bearings, reduces friction and wear at hinged joints, avoids component loosening, improves the reliability of hinged joints, and reduces maintenance costs.

Compatible with: Uses 087-0987 bearings, 087-0328 bushings, and 086-9971 dust covers. The bearing bears radial loads, the bushing provides wear-resistant support, the elastic retaining ring provides axial positioning, and the dust cover protects against foreign object intrusion, ensuring stable component operation.

Installation and Maintenance Points:

Installation: Clean the mounting groove and check the retaining ring for deformation and cracks. Use snap ring pliers to open the retaining ring and insert it into the groove, ensuring a tight fit and no looseness, and a proper fit with the bearing end face.

Maintenance: Check the retaining ring every 200 hours for deformation, breakage, or looseness. Replace immediately if any abnormalities are found to prevent bearing movement and subsequent malfunctions.

Replacement: Use snap ring pliers to remove the old retaining ring and check the mounting groove for damage; before installing the new retaining ring, check the dimensions to ensure that it fits tightly in the groove without any looseness.
