CAT 087-4766 BUSHING

CAT 087-4766 (0874766) is a Caterpillar genuine wear-resistant bushing for articulation points on construction machinery. It is compatible with 259D3/279D3 skid steer loaders and 906H/907H mini excavators, used at the articulation points of the working device. It works in conjunction with 087-1112 bearings, 087-1404 elastic retaining rings, and 087-1873 dust rings to provide wear-resistant support, reduce friction and wear at the articulation points, and ensure stable operation.

Core Parameters and Information

Item Details
Part Model: CAT 087-4766 (0874766) Hinge Point Wear-Resistant Bushing

Type: Radial Wear-Resistant Bushing for Construction Machinery Hinge Points

Material: 42CrMo alloy steel, surface hardened (hardness HRC58-62)

Key Dimensions: Inner diameter 60mm, outer diameter 70mm, length 55mm, wall thickness 5mm

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

Matching Relationship: Compatible with 087-1112 bearings, 087-1404 elastic retaining rings, and 087-1873 dust rings for wear-resistant support in hinge point assemblies.

Suitable Applications:
Suitable parts: Hinge points of skid steer loaders, mini excavators, working devices, boom and frame, connecting rods and boom, etc., suitable for frequent load changes and vibration conditions.

Application Scenarios: Suitable for outdoor operations such as excavation and loading. Provides wear-resistant support for hinge points, reduces friction between pins and bearings, minimizes component wear, prevents increased clearance leading to abnormal noise, improves the reliability of hinged parts, and reduces maintenance costs.

Compatible Features: The bushing provides wear-resistant support, the bearing bears radial loads, 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 hole and check for deformation or cracks in the bushing; use a pressing tool to smoothly press it into the mounting hole, ensuring a tight fit with the hole wall and proper alignment with the bearing and retaining ring.

Maintenance: Check the bushing for wear and deformation every 200 hours; replace it promptly if any abnormalities are found to prevent excessive clearance from damaging components.

Replacement: Remove the old bushing with a special tool and check the mounting hole for damage; verify the dimensions of the new bushing before installation to ensure a tight fit with the mounting hole and no looseness after pressing.
