Description

Overview

Pulley Idler Kit Thermo King SLX SLXe SLXi covers the paired smooth and grooved pulley positions used in the belt drive system on these trailer refrigeration units. When idler bearings grow noisy or rough, belt tracking and service confidence both suffer. Replacing the set together gives you a cleaner reset across both running surfaces instead of mixing old and new wear points.

Features

• Includes one smooth pulley and one grooved pulley in the one kit.
• Built for Thermo King SLX, SLXe and SLXi applications.
• Aftermarket version uses serviceable high temperature steel bearings.
• Suited to pulley service when bearing noise or wear shows up in operation.

Specifications and Materials

Pulley Idler Kit Thermo King SLX SLXe SLXi is the aftermarket twin-pulley kit for the matched smooth and grooved idler arrangement. Because this version uses serviceable steel bearings, the bearings can be replaced later if required. That gives you a more repair-friendly option for ongoing fleet service. Part number: TK-70-9183-AM.

Compatibility and Fitment

Check the unit series first, then confirm you need the paired smooth and grooved pulley kit rather than a single replacement pulley. Also inspect belt condition and pulley running surfaces together, because a worn belt can shorten the life of fresh bearings. This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. 70-9183, 709183, 77-3218, 773218, 77-3219, 773219

Compliance and Safety

Isolate the unit before belt and pulley work, and keep hands clear of rotating components during inspection. Thermo King maintenance schedules call for idler inspection for bearing wear and noise, so replace rough or noisy pulleys before they start affecting belt behaviour or service access.

Trailer Applications

Pulley Idler Kit Thermo King SLX SLXe SLXi fits front-mounted trailer refrigeration units where the belt drive relies on both a smooth and a grooved pulley. It suits workshop servicing when the existing pair has reached the same wear window, and it also makes sense when you want to avoid coming back for the second pulley soon after the first one fails. In busy fleet work, that paired changeout is usually cleaner than piecemeal replacement.
