Description

Overview

Thermo King Pulley Repair Kit suits SLX, SLXe and SLXi belt-drive service where the aftermarket idler or tensioner pulley remains structurally sound but the internal steel bearing components need renewal. It rebuilds the serviceable pulley instead of replacing the full assembly, so it suits repairs where the pulley body and bolt hardware still present well. When a pulley starts to feel rough or noisy, this kit gives workshops a direct way to refresh the wearable internals before belt drag or wobble gets worse.

Features

• Fits the serviceable aftermarket smooth idler and grooved tensioner pulley assemblies used on SLX, SLXe and SLXi units.
• Built for steel-bearing pulley rebuilds rather than full pulley replacement.
• Suits pulley assemblies that technicians can strip, inspect and reassemble during belt-drive service.
• Useful when bearing noise, rough rotation or play shows up during inspection.

Specifications and Materials

Thermo King Pulley Repair Kit is an aftermarket repair kit for serviceable pulley assemblies that run steel bearings instead of the non-serviceable ceramic-bearing genuine style. That matters because workshops can rebuild the matching aftermarket pulley and keep the original assembly in service when the rest of the hardware remains usable.

Part number: TK-77-3304-AM.

Compatibility and Fitment

Check the pulley type before ordering, because this kit suits the serviceable aftermarket pulley assemblies rather than the non-serviceable genuine pulley style. 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. 77-3304, 773304, TK-77-3219-AM, TK773219AM, 77-3219, 773219, TK-77-3218-AM, TK773218AM, 77-3218, 773218

Compliance and Safety

Isolate the unit before opening the pulley assembly, because belts, stored tension and rotating hardware can injure hands fast. If the pulley face shows heat damage, wobble or scoring, inspect the full assembly instead of fitting a repair kit into worn hardware. Also clean the spindle and check alignment during reassembly, because fresh bearing components will not correct a damaged mount or bent pulley path.

Trailer Applications

Thermo King Pulley Repair Kit suits workshop repairs on SLX, SLXe and SLXi units when the matching aftermarket smooth idler or grooved tensioner pulley still has a sound body. It makes sense during belt-drive strip-downs, especially when technicians catch bearing noise early and want to rebuild the serviceable pulley rather than discard the whole assembly. That approach also helps when the job already involves pulley removal and inspection.
