Frequently Asked Questions
Q: What is the IN 941008 hydraulic pump ball?
A: The IN 941008 is an Interthor OEM hydraulic pump ball designed for check valve assemblies in manual pallet jacks. It is a hardened carbon steel component precision-lapped to create a seal under high hydraulic pressure.
Q: Which pallet jack models use the IN 941008?
A: The IN 941008 is compatible with Interthor Panther and Thork Truck manual pallet jack models. Verify your equipment model designation before ordering to confirm fitment.
Q: What are the specifications for the IN 941008?
A: The IN 941008 has a nominal diameter of 0.375 inch with a tolerance of plus or minus 0.001 inch. It is constructed from hardened carbon steel with a precision-lapped surface designed to seal under hydraulic system pressures up to 4,000 PSI.
Q: Why is the IN 941008 precision-lapped?
A: The precision-lapped surface on the IN 941008 creates a tight seal against the check valve seat, preventing hydraulic fluid bypass and maintaining system pressure during pallet jack operation. The tight tolerance ensures consistent sealing performance across the 4,000 PSI operating range.
Q: What symptoms indicate the IN 941008 needs replacement?
A: Replace the IN 941008 if you observe hydraulic pressure loss, check valve leakage, reduced lift speed, or inability to hold load. Pitting, corrosion, or surface damage on the ball also indicates replacement is necessary.
Q: Is the IN 941008 compatible with other manual pallet jack brands?
A: The IN 941008 is Interthor OEM specification. While dimensions may be similar across brands, do not assume interchange without confirming diameter, material grade, and pressure rating match your equipment specifications.
