Frequently Asked Questions
Q: What is the 90916-03015 thermostat and gasket assembly?
A: The 90916-03015 is a thermostat and gasket assembly that regulates hydraulic fluid temperature in forklift and pallet jack pump systems. The thermostat opens at a set temperature to allow cooler fluid circulation, and the gasket seals the connection to prevent leaks.
Q: What equipment is the 90916-03015 thermostat compatible with?
A: The 90916-03015 thermostat and gasket is used on Crown, Toyota, Hyster, and Raymond forklifts and electric pallet jacks. Confirm your pump reservoir or motor housing has the correct port size and thread type before ordering.
Q: At what temperature does the 90916-03015 thermostat open?
A: The 90916-03015 thermostat is typically set to open at 65 to 75 degrees Celsius (150 to 170 degrees Fahrenheit). This temperature range prevents hydraulic fluid breakdown while allowing the system to reach normal operating efficiency without overheating.
Q: What symptoms indicate the 90916-03015 thermostat is failing?
A: Replace the 90916-03015 if hydraulic fluid temperature stays unusually high even during normal operation, the temperature gauge spikes and does not stabilize, fluid is leaking from the thermostat housing, or the lift system operates sluggishly due to overheat protection shutdowns.
Q: How often should the 90916-03015 gasket be replaced?
A: The gasket portion of the 90916-03015 assembly should be replaced whenever the thermostat is removed or if fluid leakage is detected around the thermostat housing. Use only the exact gasket specifications to ensure a proper seal and prevent contamination of the hydraulic system.
Q: Are there cross-reference part numbers for the 90916-03015?
A: The 90916-03015 may cross-reference to equivalent thermostats from Yale, CAT, Mitsubishi, and Jungheinrich forklifts. Contact us to verify part equivalents for your specific equipment model and verify port configuration matches your system.
