Frequently Asked Questions
Q: What are the exact dimensions and bearing specifications of the MU 77800066 load wheel?
A: The MU 77800066 is 3.35 inches in diameter and 2.76 inches in width. It features a precision ball bearing with a 20mm inside diameter (ID). The wheel has a polyurethane tread molded on a cast iron core and uses a press-fit mount design. These dimensions fit Multiton TM Series electric pallet jacks.
Q: Which Multiton electric pallet jack models use the MU 77800066 load wheel assembly?
A: The MU 77800066 is the OEM load wheel for Multiton TM Series electric pallet jacks. Verify compatibility with your equipment by checking the existing wheel diameter, width, and bearing bore size. If your model is older than the TM Series or from a different manufacturer, this wheel may not be correct.
Q: What material is the MU 77800066 wheel tread, and how does it perform in different environments?
A: The MU 77800066 features a polyurethane tread bonded to a cast iron core. Polyurethane provides good wear resistance, shock absorption, and grip on standard concrete floors. This material works well in dry warehouses and normal ambient conditions. For wet floors or cold storage, a high-traction compound wheel (EZ designation) may perform better.
Q: How do I replace the bearing in the MU 77800066 wheel assembly?
A: The MU 77800066 uses a precision ball bearing pressed into the cast iron hub. The bearing is not field-serviceable. If the bearing fails, the entire wheel assembly must be replaced. Do not attempt to repack or repair the bearing in this design.
Q: What is the expected lifespan of the MU 77800066 load wheel?
A: Under normal warehouse use, the MU 77800066 typically lasts 2 to 5 years or 5000 to 10000 operating hours before the polyurethane tread wears significantly. Heavier loads, rough floors, or frequent direction changes reduce this lifespan. Replace wheels when tread thickness drops below 10mm or visible flat-spotting occurs.
