Collection: KOMATSU LOG LOADER PINS AND BUSHINGS

Komatsu Log Loader Pins and Bushings

Komatsu log loaders operate in one of the most punishing environments in the heavy equipment industry. Continuous grapple cycling, high side-load forces, shock loading from log handling, and constant articulation place extreme stress on pivot components. Pins and bushings are the foundation of structural integrity in these machines.

WQParts supplies heavy-duty aftermarket Komatsu log loader pins and bushings engineered specifically for forestry and high-cycle material handling applications. These components are selected for proper hardness, dimensional precision, and long service life under severe-duty conditions.

Built for Forestry Applications

• High-load boom and stick pivots
• Grapple arm connections
• Heel rack pivot assemblies
• Main frame articulation points
• Continuous high-cycle rotation under load

Why Log Loader Wear Components Fail

Unlike general construction equipment, log loaders experience side loading and repetitive stress at extreme cycle rates. Poor-quality pins and bushings can lead to:

• Ovaled bores requiring line boring
• Excessive play and unsafe operation
• Cracking at structural pivot points
• Accelerated bushing deformation
• Unplanned downtime during production cycles

Material & Performance Standards

Aftermarket pins must maintain correct surface hardness and core strength to resist bending and galling. Bushings must maintain inside diameter tolerances to protect bores and control clearance. WQParts focuses on components suited for high-impact, abrasive forestry environments.
