Shop Komatsu JointsWhy Pins and Bushings Matter
Komatsu pins and bushings protect the larger structures around them. A loose pin, worn bushing, or incorrect replacement part can create movement in the joint and accelerate wear in the boom, arm, bucket linkage, loader frame, cylinder mount, or parent bore.
Once the bore is damaged, the repair may require welding, machining, or line boring. That is why WQC Parts treats pivot components as a quality-sensitive category, not just a commodity item.
- Loose joints can damage bores and linkage components.
- Incorrect bushing fit can cause spinning, movement, or premature wear.
- Incorrect pin diameter can create play or installation problems.
- Replacing one worn component without checking the mating parts can shorten repair life.
Fitment Comes First
Before ordering Komatsu pins and bushings, confirm the part number, machine model, serial number, application location, and dimensions when available.
The same Komatsu model family can use different pins, bushings, seals, spacers, or washers depending on serial range, market, attachment package, or component group. Similar descriptions may still refer to different parts.
What to Check Before Ordering
