Switch Assembly

$75.52

Fix Number: FIX11877356
Manufacturer Part Number: 23-66-3020

A cordless ratchet that will not start or cuts out during use may have a worn switch assembly. The unit combines the trigger switch, control electronics, and battery connection to manage motor operation and variable speed. First test with a known-good battery and inspect the terminals, motor, and internal wiring. Match the replacement to the full tool model because similar assemblies may use different connectors. Remove the battery before service, keep small parts organized, and route each wire through its original guide. Test the trigger only after the housing is fully secured.

Vanes

Before ordering, verify the tool model and review its parts diagram. Shut off and disconnect the compressed-air supply, then release any stored pressure. Keep internal surfaces clean during service, check the cylinder for scratches, and place each vane in the direction shown by the manufacturer before reassembly.
