Frequently Asked Questions

What boom cylinder fits a John Deere 315D backhoe?

Broken Tractor carries the AH154775 boom cylinder, which fits the John Deere 310D and 315D backhoes, plus the 410D after serial number 801200. Serial number breaks apply on boom cylinders, so check your machine's serial number and match the part number before ordering.

Which dipper cylinder seal kit fits a John Deere 315D?

It depends on which cylinder you are resealing. The AH138169-KIT fits the AH138169 dipper cylinder, and the AH154776-Kit covers the dipper/crowd cylinder on the 315D. For the extendable dipper, the AH154784-KIT fits the AH154784 cylinder. Match the part number stamped on your cylinder to the kit to get the right seals.

Do John Deere 315D cylinder pins change by serial number?

Yes, several 315D cylinder pins have serial number breaks. The T106389 boom lift cylinder tube end pin fits the 315D before serial number 814526, while the T142699 dipper cylinder tube end pin fits the 315D after serial number 780849. The T147005 outer extendible dipper stick pin fits after serial number 787832. Verify your serial number before ordering any pin.

What steering cylinder seal kit fits a 4WD John Deere 315D backhoe?

We carry two steering seal kits that list the 315D, the T153744 power steering cylinder seal kit for 4WD backhoes and the AT108329 late serial steering cylinder seal kit. We also offer the complete AT195570 power steering cylinder if you are replacing rather than resealing. Fitment on these steering parts depends on serial number, so call (800) 909-7060 to confirm the right one for your machine.

What tools do I need to reseal a John Deere 315D hydraulic cylinder?

Broken Tractor offers a hydraulic gland seal installation tool kit (CAS-1457) along with two 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 mm (4.5 to 6.7 inch) gland nuts. Measure your cylinder diameter to pick the right wrench.
