Frequently Asked Questions

Are the left and right dipper to cylinder links the same on a Komatsu PC150?

No, the left-hand and right-hand dipper to cylinder links on the Komatsu PC150 are separate parts. Broken Tractor carries the LH link with bolt holes (21K-70-23110) and the RH link (21K-70-23210) individually, so you can replace just the side you need. We also carry the 1-piece style cylinder to bucket link (21K-70-23120) and the bucket link spacer (21K-70-23130).

What bushings fit the Komatsu PC150 bucket linkage?

We carry three bushings for the Komatsu PC150 front attachment, each sold individually: the H-link bushing (21K-70-13150), the dipper at link bushing (21K-70-12170), and the dipper at bucket bushing (21K-70-22130). Buying them separately lets you replace only the worn locations instead of a full set. Matching the part number from your old bushing or parts book is the surest way to get the right one.

Which pins are available for the Komatsu PC150 excavator?

Broken Tractor offers three pins for the Komatsu PC150 front attachment pivot points: the bucket to dipper pin (21K-70-23140), the link to dipper pin (21K-70-23220), and the link to cylinder pin (21K-70-23190). We also carry the matching O-ring (21K-70-23160). If you are unsure which pin your machine uses, compare the part number or call (800) 909-7060 to confirm fitment with the parts team.

Does the Komatsu PC150 shim and seal kit fit a PC160?

Yes, the shim and seal kit (PV7009) fits both the Komatsu PC150 and PC160 excavators. We also carry an excavator seal (21K-70-12180) that fits the Komatsu PC150, PC200, PC210, and PC228UU. Confirm the part number against your machine before ordering, since fitment can vary by model.

What tool do I use to remove and install Komatsu PC150 bushings?

Broken Tractor carries a steel bushing driver tool (SKU BushingDriver) made for bushing removal and installation service work. It is a universal tool that works on excavators, so it can be used on the Komatsu PC150 H-link, dipper at link, and dipper at bucket bushings. It can be ordered alongside your bushings so you have the parts and the tool for the job.
