FAQ

Common Questions

This kit covers both skid steers and excavators — how do I know it's correct for my Bobcat E45 excavator?

Part number 7135559 is listed by Bobcat as the correct seal kit for the arm and bucket cylinders on the E14, E17, E17Z, E35, E35i, E42, E45, E50, and E55 excavators, as well as the 335, 337, 341, 430, and 435 compact excavators. If your E45 cylinder is leaking, this is the right kit. Confirm the rod diameter matches before disassembly — call (818) 261-3896 if you need help.

I have a Bobcat BL375 backhoe loader — does this kit cover the boom cylinder, the stick cylinder, or the bucket cylinder?

Part number 7135559 is confirmed for Bobcat backhoe loaders B100, B200, B250, B300, BL275, BL370, and BL375. However, backhoe loaders have multiple cylinders (boom, stick, bucket). Measure your leaking cylinder's rod diameter and bore to confirm this kit is sized correctly for the specific cylinder you're rebuilding. Call us at (818) 261-3896 for help identifying which cylinder is which on your BL375.

How does this kit compare to SKU 2509 (6806330) — both seem to fit similar Bobcat models?

These two kits cover overlapping machines but different cylinders. SKU 2509 (6806330) is the tilt cylinder kit for S150/S160/S175/S185/S205/T180/T190 — sized at 1-1/4" rod and 2-1/2" bore. This kit (7135559) is the correct cylinder seal kit for 773/S175/S185/S205/T190 as well as excavator and backhoe applications. The safe approach: measure your cylinder's rod and bore, match it to the specs, and call (818) 261-3896 to confirm before ordering.
