Frequently Asked Questions
Q: What Hyster electric lift truck models use the HY 368436 seal ring?
A: The HY 368436 is referenced for select Hyster A203 and A20-30XL series models. This seal ring is designed for mast and hydraulic assemblies in these electric lift truck platforms. Confirm your specific truck model and serial number against Hyster documentation to verify compatibility before ordering.
Q: What is the double-case construction on the HY 368436, and what does it provide?
A: The HY 368436 features double-case construction, meaning the seal casing has two layers or reinforced design. This increased robustness improves structural integrity during installation, resists deformation under load cycling, and provides greater installation reliability in mast and hydraulic assemblies. Double-case design extends seal life in demanding warehouse environments.
Q: Is the HY 368436 a double-lip dust and oil seal?
A: Yes. The HY 368436 is a double-lip design that functions as both a dust seal and oil seal. It excludes contaminants (dust, moisture, debris) while retaining lubricant in mast and hydraulic systems. This dual function is essential for protecting moving components in Hyster A203 and A20-30XL series trucks.
Q: What are the manufacturer part numbers for the HY 368436?
A: The OEM part number is 368436, and the manufacturer part number is HY 368436. Both designations refer to the same seal ring. Use these numbers when cross-referencing your Hyster equipment documentation or parts catalogs.
Q: Where does the HY 368436 seal typically fail, and what causes it?
A: Seal failure typically occurs from contamination ingress (dirt or moisture bypassing the dust lip) or lip wear from repetitive mast cycling and pressure fluctuations in hydraulic circuits. Double-lip construction on the HY 368436 provides extended protection, but seals should be inspected during routine mast service intervals and replaced if lip wear or hardening is visible.
