CAT 087-0328 BUSHING

CAT 087-0328 (0870328) 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 086-9824 needle roller bearings, 086-8559 elastic retaining rings, and 086-9971 dust covers, providing wear-resistant support and radial positioning, reducing wear at the articulation points, and ensuring stable Cat® operation…

Core Parameters and Information

Item Details
Part Model: CAT 087-0328 (0870328) Hinge Point Wear-Resistant Bushing

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

Material: Outer layer 45# steel, inner lining copper alloy (CuSn10Pb10), surface self-lubricating coating

Key Dimensions: Inner diameter 55mm, outer diameter 60mm, length 30mm, wall thickness 2.5mm, coating thickness 0.05mm

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

Matching Relationship: Compatible with 086-9824 needle roller bearings, 086-8559 elastic retaining rings, 086-9971… Dust cover for use in articulation point assemblies.

Compatibility and Applications:
Suitable Parts: Articulation points of skid steer loaders, mini excavator booms and frames, connecting rods and booms, etc., suitable for frequent load-changing operations (Cat®…).

Application Scenarios: Provides wear-resistant support and radial positioning for frequent load-changing operations such as excavation and loading, reducing wear at articulated points, preventing component loosening, lowering the risk of failure, and improving operational safety and reliability.

Compatible Use: Uses with 086-9824 needle roller bearings, 086-8559 elastic retaining rings, and 086-9971 dust covers. 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 (Cat®…).

Installation and Maintenance Points:
Installation: Clean the mounting holes and check the bushing dimensions; press the bushing into the mounting holes, ensuring a tight fit against the hole walls; assemble with the bearing, retaining ring, and dust cover in sequence, ensuring accurate axial positioning and no loosening.

Maintenance: Inspect the bushing for wear, deformation, and cracks every 200 hours; regularly add grease to maintain good lubrication and extend service life.

Replacement: Remove the old bushing with a special tool and check the mounting holes for damage; verify the dimensions of the new bushing before installation to ensure a tight fit with the mounting holes without any looseness.
