Komatsu Part SHIM 421-22-32470

—

Product Overview

The 421-22-32470 SHIM is a genuine Komatsu OEM replacement shim. Shims enable precise dimensional adjustment during assembly — compensating for the tolerance stack-up that is inherent in any assembly of multiple machined components. The difference between a correctly shimmed assembly and an incorrectly shimmed one is measured in service life.

When to Replace

• The shim is physically damaged — bent, torn, crushed, or corroded
• Clearance or preload measurements during assembly show incorrect shim pack thickness
• The assembly is being rebuilt — shim measurements must be verified
• The shim shows uneven wear — indicating it has been running with improper clearance
