CL-1642

Frequently Asked Questions

Q: What is the CL-1642 retainer-brake seal used for?
A: The CL-1642 is an OEM retainer-brake seal that secures the seal cartridge in the hydraulic brake assembly of manual pallet jacks. It prevents seal drift and maintains hydraulic pressure containment during brake engagement and load holding.

Q: Which Clark pallet jack models are compatible with the CL-1642?
A: The CL-1642 is engineered for Clark standard series manual pallet jacks. Alternate part number references include CL1642 and CL 1642. Verify your pallet jack model matches Clark standard series documentation before ordering.

Q: What material is the CL-1642 retainer-brake seal made from?
A: The CL-1642 is manufactured from engineering-grade polymer or equivalent material. This composition resists hydraulic fluid degradation and maintains seal compression over extended service life in brake assemblies.

Q: What are the symptoms of a failed retainer-brake seal on a Clark pallet jack?
A: Signs of seal failure include brake fluid leaks, loss of brake pressure, inability to hold a load on inclines, or visible hydraulic fluid around the brake assembly. A failed seal must be replaced to restore safe brake operation.

Q: Is the CL-1642 seal compatible with pallet jacks from other manufacturers?
A: The CL-1642 is an OEM Clark component manufactured to Clark specifications. Do not substitute with non-Clark seals unless cross-reference documentation confirms dimensional and material compatibility with your equipment.

Q: How long does a retainer-brake seal typically last on a Clark manual pallet jack?
A: Service life depends on usage frequency, load cycles, and maintenance. High-use warehouse pallet jacks may require seal replacement annually or sooner. Inspect seals regularly for leaks and fluid degradation.
