Blower to Alternator Belt Thermo King SLX SLXe SLXi
$100.00
Blower-to-alternator drive belt for matched Thermo King SLX, SLXe and SLXi applications, used where belt wear, glazing or cracking starts to affect blower and alternator drive performance during service.
Part number TK-78-1945-OP.
Description
Overview
Blower to Alternator Belt Thermo King SLX SLXe SLXi drives the blower and alternator on matched Thermo King refrigeration unit layouts. When the belt wears, stretches or glazes, accessory drive performance drops, so replacing it early helps keep the belt path stable and the driven components turning properly. This matters on units that run several nearby belts across the same drive system.
Features
- Fits the blower-to-alternator belt position on matched SLX, SLXe and SLXi applications
- Uses the Optibelt version under the ICS sellable SKU
- Targets common wear signs such as cracking, glazing, noise and age-related hardening
- Includes cross-reference coverage for older Thermo King belt numbers still found in service records

Compatibility and Fitment
Check the belt position before ordering, because similar Thermo King references cover fan, water pump and compressor positions on the same unit family. Blower to Alternator Belt Thermo King SLX SLXe SLXi fits SLX, SLXe and SLXi applications where the blower-to-alternator drive layout matches the installed 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. 78-1945, 781945, 78-1507, 781507, 781-507, 78-1744, 781744, 781-744, 78-1340, 781340, 781-340, 78-1108, 781108, 781-108, 78-1337, 781337, 781-337, 78-1831, 781831, 781-831, 1E32438H09
Compliance and Safety
Inspect pulley condition and belt alignment before fitting the new belt, then recheck tracking after the first run-up. If the previous belt failed early, inspect neighbouring driven components as well so the new belt does not run against a damaged pulley or a misaligned drive path.
Trailer Applications
Blower to Alternator Belt Thermo King SLX SLXe SLXi suits transport refrigeration service work where the blower and alternator belt needs replacement without disturbing other belt positions. It also helps fleets with mixed service history, because older packing labels and workshop notes still use earlier Thermo King belt references for the same belt position. That gives stores and workshops a cleaner way to support SLX, SLXe and SLXi units across routine maintenance and corrective repair work.
