Frequently Asked Questions

What pins fit the bucket linkage on a Kobelco SK135 excavator?

Broken Tractor carries three linkage pins for the Kobelco SK135: the bucket to dipper or H-link pin (2419P4031D1), the link to dipper arm pin (2419P4050D2), and the link to cylinder pin (2419P4049D2). Each pin is sold individually and is listed to fit the SK115, SK120, SK130, SK135 and MD140. Match the part number on your old pin to make sure you order the right one for each position.

Do Kobelco SK115-SK135 pins and bushings fit a Kobelco SK100?

Only some of them do. The heavy-duty link bushing (2405T824) and the H-link open end seal (2445R138D3) are listed for the SK100, while the other pins, links, bushings and seals are listed for the SK115, SK120, SK130, SK135 and MD140. If you run an SK100, check each part number against your machine before ordering.

What is the difference between the left-hand and right-hand bucket links for a Kobelco SK120?

The right-hand bucket link (2406P4866D1) and the left-hand bucket link with bolt holes (2406P4866D2) are separate parts, so you order the side you need. Both are listed to fit the Kobelco SK115, SK120, SK130, SK135 and MD140. We also carry the complete H-link (2406N795F1) for the same models.

What does the Kobelco heavy-duty link bushing 2405T824 replace?

The heavy-duty link bushing 2405T824 replaces two OEM bushings with a single piece. It is listed to fit the Kobelco SK100, SK115, SK120, SK130, SK135 and MD140. If you are not sure which bushings it replaces on your excavator, call (800) 909-7060 and the parts team can confirm fitment.

What seals and bushings do I need to rebuild the H-link on a Kobelco SK130?

For the Kobelco SK130 H-link, Broken Tractor offers the H-link closed end bushing (2405T825), the H-link open end seal (2445R138D3), the H-link closed end seal (2445R220D2) and the O-ring (2445Z869). The dipper stick bushing at the bucket (2405P472) is also available for the same models. A steel bushing driver removal and installation tool is offered for pressing bushings in the shop or in the field.
