Frequently Asked Questions

Which loader lift cylinder seal kit fits a John Deere 315SG?

Broken Tractor carries loader lift cylinder seal kit AH146874-KIT, which fits the John Deere 315SG before serial number 910491. Check your machine's serial number before ordering, since fitment depends on it. If your 315SG falls outside that range or you are unsure, call (800) 909-7060 and the parts team can help confirm the right kit.

What bucket cylinder seal kit do I need for a JD 315SG backhoe?

It depends on your bucket cylinder lift configuration. We carry a standard lift bucket cylinder seal kit (AH149790-KIT) and a heavy duty bucket cylinder seal kit (AH219638-KIT), and both fit the 315SG. Verify whether your machine has the standard or heavy lift setup, and match the part number on your existing cylinder, before ordering.

Can I replace the whole dipper or swing cylinder on a John Deere 315SG instead of resealing it?

Yes, Broken Tractor offers complete cylinders for the 315SG, including the dipper arm cylinder (AH164137), the swing cylinder (AHC11321) and the power steering cylinder (AT195570). If you would rather reseal, we also carry seal kits for the boom cylinder (AH211132-KIT) and dipper cylinder (AH164137-KIT). We also offer a replacement stabilizer cylinder rod (AH147902) that fits the 315SG.

Which steering cylinder seal kit fits a 4WD John Deere 315SG?

We carry two steering cylinder seal kits that list the 315SG: the power steering cylinder seal kit for 4WD backhoes (T153744) and the steering cylinder seal kit for 4x4 backhoes (T213801). Fitment can vary by machine, so match the part number on your existing steering cylinder before ordering. A complete power steering cylinder (AT195570) is also available if the cylinder needs replacing rather than resealing.

What tools help with resealing JD 315SG hydraulic cylinders?

Broken Tractor carries a hydraulic gland seal installation tool kit (CAS-1457) and two hydraulic cylinder spanner wrenches for removing gland nuts. The JD-51120 wrench fits 2 to 4.75 inch diameter cylinders, and the JD-115170 wrench fits 115 to 170 millimeter (4.5 to 6.7 inch) gland nuts. Measure your cylinder or gland nut to pick the right spanner wrench.
