CAT 093-1600 RETAINER

CAT 093-1600 (0931600) is a Caterpillar original equipment manufacturer (OEM) axial retainer (circlip) for articulation points on construction machinery. It is compatible with the articulation points of the working devices of 259D3/279D3 skid steer loaders and 906H/907H mini excavators. It is used in conjunction with 092-5172 bearings, 090-9624 bushings, and 090-9289 retaining rings to axially position the bearings/bushings, preventing displacement during operation and ensuring stable operation of the articulated joint.

Core Parameters and Information

Item Details
Part Model: CAT 093-1600 (0931600) Elastic Retaining Ring Type Fixer

Type: Elastic retaining ring (circlip) for construction machinery shafts, axial positioning component

Material: 65Mn spring steel, blackened surface oxidation, excellent elasticity, wear and corrosion resistance, suitable for outdoor working conditions

Key Dimensions: Inner diameter φ70mm, thickness 2.5mm, opening width 8mm, suitable pin shaft diameter φ70mm, groove width 2.5mm, depth 1.3mm

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

Matching Relationships: Compatible with 092-5172 bearings, 090-9624 bushings, 090-9289 retaining rings, 087-1873 Dust ring accessories are used for axial fixation of articulated joint assemblies.

Suitable for:
Suitable parts: Articulated joints of skid steer loaders, mini excavators (boom and frame, connecting rod and boom, etc.). Installed in the pin groove, it axially limits the bearings and bushings, preventing movement under varying loads and vibrations, and avoiding abnormal noise and wear.

Application scenarios: Suitable for complex outdoor working conditions such as excavation and loading. It relies on elastic deformation to lock in the groove, providing reliable fixation and easy maintenance.

Core functions: Axial positioning, preventing movement, ensuring accurate bearing and bushing installation, improving the operational stability of articulated joints, and reducing maintenance frequency.

Installation and maintenance points:
Installation: Clean the pin groove, use external snap ring pliers to open the retainer, and smoothly insert it into the groove, ensuring it is fully engaged without loosening; assemble with bearings, bushings, etc., ensuring an axial clearance of 0.1-0.3mm for smooth operation.

Maintenance: Check the retainer for deformation, breakage, or loosening every 200 hours. Replace any abnormal parts immediately to prevent bearing/bushing displacement and damage.

Replacement: Remove the old part with snap ring pliers and check for wear in the pin groove. Before installing the new part, verify its dimensions to ensure it matches the groove. After installation, test the hinge area for any abnormalities.
