Thread GuardThis thread guard (part number AC146474) is an aftermarket replacement used to protect threaded shafts and rods on forklifts from damage, dirt, and impact. The guard shields fragile threads during operation so adjustment, removal, and reassembly remain straightforward at the next service. Maintenance techs replace thread guards when they crack, deform, or go missing. Restoring this small protective component saves much larger costs that occur when damaged threads force replacement of full shafts or rods in a forklift drive or steer assembly.Aftermarket replacement part, cross-references original part number AC146474.Need help confirming fit?
