Frequently Asked Questions
Q: What equipment does the 800065185 seal kit fit?
A: SKU 800065185 is an OEM seal kit replacement for the Bishamon BS-55 manual pallet jack. It provides pressure-retaining and wiper seals for the hydraulic unit on this specific model.
Q: What materials are in the 800065185 seal kit?
A: The 800065185 contains seals manufactured from NBR (nitrile rubber) and polyacetal materials. These materials provide chemical resistance to ISO VG 32/46 hydraulic oils and maintain sealing integrity under pressure cycling.
Q: What pressure rating does the 800065185 seal kit handle?
A: The 800065185 seal kit is rated for hydraulic circuits up to 3000 PSI working pressure. Do not use this kit in systems operating above this rating, as seal failure and hydraulic fluid loss will result.
Q: What hydraulic oil types work with the 800065185?
A: The 800065185 seal kit is compatible with ISO VG 32 and ISO VG 46 hydraulic oils. These are standard mineral oil grades for Bishamon manual pallet jacks. Do not use synthetic or non-standard oils without confirming compatibility with your equipment manufacturer.
Q: What seal kit does SKU 800065185 replace?
A: SKU 800065185 supersedes equivalent Bishamon seal kits and OEM part number BI 52103704. It serves as the direct replacement for original Bishamon BS-55 hydraulic unit seals.
Q: What happens when seals in the 800065185 kit fail?
A: Worn or failed seals cause hydraulic fluid leakage, loss of lifting pressure, and inability to raise or lower the pallet jack. The hydraulic unit may also become contaminated with air or water, leading to spongy operation and complete system failure.
