frequently ask questions

Typical signs include external oil leakage, pressure loss, slower performance, overheating, contamination in the oil, and oil weeping around the shaft or housing. If leaks appear repeatedly, seals may be worn or the wrong kit may have been installed.

The fastest method is the part number for the pump/motor or the seal kit number. If that isn’t available, send a nameplate photo, machine model, and clear photos of the sealing area. Dimensions can also help when confirming a match.

Yes. East Diamond supplies seal kits and repair kits for hydraulic pumps and hydraulic motors, including shaft seals and related sealing components used in common overhaul work.

Common causes include incorrect kit selection, installation damage (pinched seal lips), shaft wear, contaminated oil, or misalignment. If you share your pump model and photos, we can help confirm the correct kit for your configuration.

Early failure is often linked to heat, contamination, incorrect oil, pressure spikes, dry running, damaged shafts, or installation without proper lubrication. Using the correct seal material and correct kit for the application helps reduce premature wear.

We supply complete seal kits and repair kits, and in many cases can also supply supporting sealing components such as O-rings and shaft seals depending on the model and requirement.

East Diamond strives to provide high quality hydraulic pumps, parts and motors to mining, construction and agricultural industries. We will constantly challenge ourselves to explore new grounds with innovation and drive.
