Motor to Compressor Belt Thermo King T-Series
Motor to Compressor Belt Thermo King T-Series
$65.00
Motor to compressor belt for Thermo King T-Series units including T-880R, T-800R, T-680R and T-580R, built for the six-groove standby drive that turns the compressor from the electric motor when the fitted belt shows slip or glazing.
Part number TK-78-1822-AM.
Description
Overview
Motor to Compressor Belt Thermo King T-Series runs the compressor from the electric motor on matched T-Series standby units, so it keeps refrigerant flow moving when the unit switches away from engine drive. When this belt slips, glazes, or cracks, compressor speed drops and standby performance can suffer.
Features
- Fits the electric motor to compressor belt path used on T-880R, T-800R, T-680R and T-580R applications.
- Uses a 6-groove profile, so buyers can match rib count before ordering.
- Suits compressor-side standby drive service, not the engine-to-motor or water pump positions.
- Makes sense to inspect pulley alignment and tension at the same time if the removed belt shows edge wear or rib polishing.
Specifications and Materials
Motor to Compressor Belt Thermo King T-Series uses a six-groove layout for the motor-to-compressor drive on matched units. Part number: TK-78-1822-AM.
For T-Series unit and compressor drive context, see the manufacturer technical guide
Compatibility and Fitment
Match the unit model, belt path, and groove count before ordering, because T-Series units can carry more than one belt in the same drive area. If the unit uses electric standby, check that you are replacing the motor-to-compressor belt rather than the water pump or engine-drive belt.
This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. 78-1822, 781822, 781-822, 1E46118H89
Compliance and Safety
Shut the unit down and isolate standby power before service, because belts, pulleys, and the compressor drive can move without warning. After installation, set tension correctly and recheck tracking after the first run, otherwise a new belt can wear quickly.
Trailer Applications
Motor to Compressor Belt Thermo King T-Series suits front-mounted T-Series refrigeration units where the electric motor drives the compressor during standby operation. It fits the service role shown for T-880R, T-800R, T-680R and T-580R applications, so it belongs in standby belt repairs where the fitted 6-groove belt has started to squeal, polish, or shed dust.
