Komatsu Wheel Loader Pins & Bushings
Komatsu wheel loader pins and bushings protect loader linkage, boom, bucket, and cylinder pivot points from looseness and bore wear. Use this WQC Parts page to move from a WA-series loader repair need to the correct aftermarket Komatsu replacement pin, bushing, linkage part, or quote path.
Common Wheel Loader Pivot Areas
Loader Boom Pivots
Main lift-arm and boom-to-frame pivots carry high loader cycle loads and need close fitment confirmation.
Bucket and Bellcrank Linkage
Bucket linkage pins and bushings see impact, breakout force, material contamination, and repetitive loading.
Cylinder Mount Pivots
Lift, tilt, and steering cylinder pivots should be checked for pin wear, bushing wear, and bore elongation.
How to Research WA-Series Loader Parts
Komatsu WA-series loader parts may vary by model generation, serial number, bucket linkage arrangement, and application. Before ordering, confirm the loader model, serial number, pivot location, existing part number, and whether the machine has a standard bucket, coupler, or special attachment.
- WA200, WA250, WA320, WA380, WA400, WA470, WA500, and larger loaders can have different linkage designs by series.
- Wheel loader pins and bushings should be checked together because a new pin in a worn bushing usually does not fix looseness.
- If the bore is worn, replacing only the pin and bushing may not restore the correct fit.
WQC Parts Support for Loader Pivot Repairs
WQC Parts helps buyers research aftermarket Komatsu wheel loader pins and bushings by part number, dashless number, model family, and serial range. When the part is covered by a WQ Certified™ standard, we focus on fit, material, hardness, finish, and dependable heavy-equipment pivot performance.
Common Questions
What information is needed for a wheel loader pin quote?
Send the Komatsu part number if available, plus the WA model, serial number, pivot location, and photos of the old part or linkage.
Should pins and bushings be replaced together?
Often yes. If one side of the pivot is worn, replacing only the pin or only the bushing can leave looseness in the joint.
Need help confirming fitment? Send WQC Parts the Komatsu part number, machine model, serial number, and pivot location. We can help narrow the correct aftermarket replacement path before you order.
