Specs At A Glance

Good To Know

Q: How do I know if this belt fits my Thermo King unit? A: Verify the model is MD-II or MD-II MAX and that the existing belt number is 78-1083 or 781083. Serial number differences can affect routing, so cross-check before installing.

Q: What happens if I run a worn belt? A: A worn belt can slip, causing compressor under-drive and reduced cooling capacity. Early replacement prevents damage to the engine pulley and belt tensioner.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
