Frequently Asked Questions
What John Deere 310 backhoe hydraulic cylinder seal kits do you carry?
Broken Tractor carries seal kits for every major cylinder on the John Deere 310 backhoe: boom, dipper crowd, bucket, stabilizer outrigger, swing and steering. Coverage includes the 310, 310A, 310B and 410, though each kit has its own model and serial number fitment. Check the fitment listed on each kit before ordering.
Does the serial number matter for John Deere 310B hydraulic cylinder seal kits?
Yes, serial number breaks apply on several John Deere 310B kits. The boom and bucket seal kits fit the 310B before serial number 701219, and the stabilizer seal kit fits the 310B before serial number 701220. The bucket kit fits the 410 after serial number 335231. If you are unsure which side of a break your machine falls on, call (800) 909-7060 with your serial number before ordering.
How do I match a seal kit to my John Deere 310 backhoe hydraulic cylinder?
The easiest way is to match the cylinder part number on your machine to the kit listing. The boom seal kit fits the AR90447 cylinder, the bucket seal kit fits the RE18757 cylinder, and the swing seal kit fits the AT56433 cylinder. The dipper crowd kit is marked with an asterisk for the 310B, so confirm your cylinder part number or serial number before ordering it.
Can I repair a John Deere 310 backhoe hydraulic cylinder instead of replacing it?
Yes, you can reseal the existing cylinder with a seal kit instead of buying a complete replacement cylinder. Broken Tractor offers repair kits for the boom, dipper, bucket, stabilizer, swing and steering cylinders on 310 series backhoes. These kits are made to restore sealing and performance at each cylinder position.
What tools do I need to rebuild a John Deere 310 backhoe hydraulic cylinder?
We carry a hydraulic gland seal installation tool kit and two hydraulic cylinder spanner wrenches for John Deere backhoe cylinder work. One spanner wrench fits 2 inch to 4.75 inch diameter cylinders. The other fits 115 mm to 170 mm gland nuts, which is about 4.5 inch to 6.7 inch. Measure your cylinder or gland nut diameter to choose the right wrench.
