Pump and Motor Assembly, 24V
Frequently Asked Questions
Q: What is the CR 089670 pump and motor assembly used for?
A: The CR 089670 is a 24V DC pump and motor assembly for Crown electric lift trucks. It supplies hydraulic pressure to the mast and lift mechanism, delivering the force needed to raise, lower, and tilt loads.
Q: What voltage and power output does the CR 089670 provide?
A: The CR 089670 operates at 24 volts DC and is designed for Crown electric pallet jacks and walkie stackers. Verify your truck battery voltage matches 24V before installation. Incorrect voltage will damage the motor windings.
Q: Which Crown lift truck models are compatible with the CR 089670?
A: The CR 089670 fits multiple Crown electric pallet jack models from specific production years. Cross-reference your equipment serial number and model designation with the original part number stamped on your existing pump motor assembly to confirm fit.
Q: What maintenance does a pump and motor assembly require?
A: Check hydraulic fluid level and condition every 40 operating hours. Keep hydraulic fluid clean and at the correct viscosity to prevent pump wear and motor burnout. Inspect electrical connections and wiring for corrosion or damage regularly.
Q: How long does a pump and motor assembly typically last?
A: A well-maintained pump and motor assembly lasts 8 to 12 years under normal duty. Lifespan decreases significantly with dirty hydraulic fluid, contaminated air intake, or overloaded operation beyond the truck rated capacity.
Q: What signs indicate pump and motor failure?
A: Symptoms include reduced lift speed, weak load holding, electrical humming without hydraulic output, grinding or squealing noise, hot hydraulic fluid, or complete loss of pump pressure. These indicate internal wear, cavitation, or motor winding failure.
