Frequently Asked Questions

What John Deere 310 backhoe hydraulic cylinder seal kits does Broken Tractor carry?

We carry aftermarket seal kits for the boom, dipper crowd, bucket, stabilizer and swing cylinders on the John Deere 310A and 310B backhoe, plus loader lift, loader bucket tilt and steering cylinder seal kits. Several of these kits also fit the 310 and 410. Some cylinders changed during production, so match the kit to the cylinder position and your machine's serial number before ordering.

Which boom cylinder seal kit fits a John Deere 310B backhoe?

It depends on the serial number. The AR105355 kit fits the AR90447 boom cylinder on 310A and 310B machines before serial 701219, and it also fits the 310 and 410. Machines after serial 701219 use the RE12719-KIT boom cylinder packing kit. If you are unsure which cylinder you have, check your serial plate or call (800) 909-7060 to confirm with the parts team.

Which bucket cylinder seal kit fits a John Deere 310A or 310B?

On a 310B, the bucket cylinder kit depends on serial number. The RE18757-KIT fits the RE18757 cylinder on 310B machines before serial 701219, and the RE18758 bucket cylinder rebuild kit is listed for 310A and 310B machines after serial 701220. Both kits are listed for the 310A, so compare the part number on your cylinder to the kit before you order.

What tools do I need for John Deere 310 backhoe hydraulic cylinder repair?

Along with the correct seal kit, Broken Tractor offers a hydraulic gland seal installation tool kit and two hydraulic cylinder spanner wrenches for removing gland nuts. One spanner wrench fits 2 to 4.75 inch diameter cylinders, and the other fits 115 to 170 mm (about 4.5 to 6.7 inch) gland nuts. Measure your cylinder to choose the right wrench size.

Do you carry extendible dipper cylinder parts for the John Deere 310B backhoe?

Yes, we carry the B28568 extendible dipper cylinder rod end pin, which fits the 310A and 310B as well as the 310C, 310D and 410. We also offer the T79781 inner extendible dipper cylinder gland bushing, which fits the 310B after serial 709859 along with the 410C and 410D. Check your serial number to confirm the bushing fits your machine.
