Description

Overview

Key Crankshaft Compressor Thermo King suits X426 LS and X430 LS compressor applications where the shaft key locates the matched drive component on the crankshaft. It is a small part, but it matters because a damaged or missing key can let the drive side lose its proper seat. When the compressor is apart for repair, this replacement key helps restore that keyed connection.

Features

• Suits Thermo King X426 LS and X430 LS compressor applications
• Fits the crankshaft key position on compatible compressor assemblies
• Useful when the original key is worn, damaged, or missing
• Aftermarket replacement for compressor repair and reassembly work

Specifications and Materials

Key Crankshaft Compressor Thermo King covers compatible compressor service where the crankshaft key must seat correctly before reassembly. It suits buyers replacing a failed key during strip-down work rather than substituting a general hardware item.

Part number: TK-55-9032-AM.

Compatibility and Fitment

Match the compressor model and inspect the shaft slot, hub, and mating keyway before ordering. If burrs or fretting marks are present, clean them first so the new key can seat fully.

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. 55-9032, 559032, 559-032, 1B18484H08

Compliance and Safety

Fit the key into a clean slot and check that the mating component slides on square, because a raised burr can stop full seating. Do not force the assembly together, and correct any shaft or hub damage first so the key does not rock, crush, or shear in service.

Trailer Applications

This part suits trailer refrigeration repairs that use X426 LS or X430 LS compressors, especially when the drive side is already apart for service. It also suits jobs where a worn key has let the mating component loosen, so the compressor can be rebuilt with the correct retaining piece in place.
