Frequently Asked Questions

What seal kit fits a John Deere 744H hydraulic cylinder?

The correct kit depends on the bore diameter of the specific cylinder being rebuilt. We carry kits such as the 90 mm bore AHC19979, which fits a range of John Deere machines including the 744 series wheel loaders. Match the bore size or the part number to confirm the right fit.

How do I know which cylinder seal kit I need for a 744K?

Identify the cylinder bore diameter and the cylinder function, since boom, bucket, and steering cylinders can use different kits. Measuring the bore is the most reliable way to select the correct seal kit. If you are unsure, call our parts team at (800) 909-7060 and we can help match it.

What is included in a hydraulic seal kit for the 744L?

Seal kits typically include rod seals, piston seals, wipers, o-rings, and backup rings needed to rebuild the cylinder. Contents vary by kit and bore size. Confirming the part number ensures you receive the correct components.

Can I rebuild a leaking cylinder on a 744P instead of replacing it?

Yes, a leaking cylinder can often be serviced with a seal kit rather than replacing the entire cylinder. This is a common repair when the rod and bore are still in good condition. Broken Tractor offers seal kits to support these rebuilds.
