Frequently Asked Questions

Do R200LC and R210LC Hyundai excavators use the same cylinder seal kits?

Yes, the R200LC and R210LC share the same boom, arm and bucket cylinder seal kits. We carry the boom cylinder seal kit 91E1-2706, the arm cylinder seal kit 91E1-2707 and the bucket cylinder seal kit 91E1-2708 for both models. The later R210LC-7 uses different 31Y1 prefix kits, so check your exact model before ordering.

What bucket cylinder fits a Hyundai R210LC9 excavator?

Bucket cylinder 31Q6-60111 fits the Hyundai R210LC9, along with the R210LC9BC, R210LC9BH, R210NLC9, R210W-9, R210W9A and R210W9S. The same cylinder also fits the R220LC9A, R220NLC9A, R235LCR9, R235LCR9A, R300LC9S, R300LC9SH and R380LC9DM. Matching the part number on your old cylinder is the best way to confirm fitment.

Which seal kits fit a Hyundai R210LC-7 long reach excavator?

For R210LC-7 long reach machines, Broken Tractor offers the long reach arm cylinder seal kit 31Y1-06731N and the long reach bucket cylinder seal kit 31Y1-13800N. Standard reach R210LC-7 machines use a different arm cylinder seal kit, 31Y1-15230N. Confirm whether your machine has a long reach front before ordering.

Are Hyundai excavator boom cylinder seal kits different for the left and right side?

On some models they are, so the side matters when ordering. For the R210LC-7 we carry right hand boom cylinder seal kits 31Y1-15880N and 31Y1-15700N, and for the R160LC-7 we offer a left hand boom cylinder seal kit along with the standard 31Y1-20430 kit. If you are not sure which side or version your machine needs, match the part number on your cylinder or call (800) 909-7060.

Should I buy a complete Hyundai excavator cylinder or just a seal kit?

Broken Tractor carries both, so you can rebuild your existing cylinder with a seal kit or replace it with a complete assembly. Seal kits cover boom, arm and bucket cylinders for models like the R130LC, R160LC-7, R280LC, R320LC-1, R420LC and R450LC. Complete arm and bucket cylinder assemblies are offered for R-7 and R-9 series machines, such as arm cylinder 31N9-50131 and bucket cylinder 31N9-60110 for the R320LC-7 and R320LC-7A.
