Frequently Asked Questions
Q: What models use the TJ19102-33102 rotor?
A: The TJ19102-33102 rotor is designed for Toyota electric forklifts with 48-volt systems, specifically models 7FGU25 through 7FGU35 from 2005 onwards. Confirm your equipment model and year against the parts diagram before ordering.
Q: What are the specifications for TJ19102-33102?
A: Outer diameter is 5.5 inches with a 1.5-inch inner bore. The rotor thickness is 0.75 inches and weighs approximately 4.2 pounds. The friction surface is rated for maximum continuous braking loads of 8000 pounds force.
Q: Can this rotor be used on different voltage systems?
A: No. The TJ19102-33102 is engineered for 48-volt brake systems only. Using it on 24-volt or 80-volt systems will result in incorrect braking response and safety hazards. Always match the rotor voltage rating to your equipment specification.
Q: What causes rotor wear and how is it measured?
A: Wear is caused by friction surface contact with brake pads during braking cycles. Measure thickness at three points around the rotor face using a caliper. Replace when thickness falls below 0.3 inches or when visual inspection shows uneven wear patterns or heat discoloration.
Q: Is the TJ19102-33102 equivalent to any other part numbers?
A: Yes. The Toyota direct OEM number is 42431-23230-81. The aftermarket cross-reference SKU is GW-TJ19102-33102. Always confirm compatibility by checking the original part number stamped on your equipment before ordering.
Q: What should I know about rotor storage and shelf life?
A: Store rotors in a dry environment protected from moisture and salt air to prevent rust formation on the bore. Cast iron rotors have indefinite shelf life if stored properly. Keep the friction surface clean and free from oil or grease before installation.
