RESERVOIR
Frequently Asked Questions
Q: What is the purpose of the 7807890 reservoir in manual pallet jacks?
A: The 7807890 reservoir stores hydraulic fluid for manual pallet jack pump systems. It maintains fluid volume and thermal stability during normal operation on Crown, Toyota, Raymond, and comparable manual pallet truck models. This part is essential for sustained pump pressure and lift cycle performance.
Q: How do I know if the 7807890 reservoir needs replacement?
A: Replace the 7807890 if you observe slow or incomplete lift cycles, visible fluid seepage around the tank seams, discolored or degraded hydraulic fluid, or cracks in the plastic or metal housing. A failing reservoir typically causes performance loss that cannot be resolved by fluid level adjustment alone.
Q: Is the 7807890 compatible with all manual pallet jack models?
A: The 7807890 fits standard manual pallet jack pump assemblies used across multiple OEM brands. Verify that your equipment has a compatible pump system before ordering. Contact us with your equipment model and serial number to confirm correct fitment.
Q: What maintenance does the 7807890 reservoir require?
A: Check fluid level monthly and maintain it between minimum and maximum marks. Use ISO VG 46 hydraulic fluid or equivalent. Inspect the reservoir for cracks or leaks during routine inspections. Replace hydraulic fluid every 2 to 3 years depending on usage frequency and operating conditions.
