The Komatsu 561-74-61540 (5617461540) shim plate is an essential alignment component tailored for heavy-duty Komatsu machinery including the HD785-3, HD785-5, HD785-7 and HD985-3/5 models. Engineered from durable steel and manufactured to precise thicknesses (T = 1.0 mm variant commonly listed) this shim plate fills mounting gaps and corrects structural tolerances that occur during intense use.
Installation of the 561-74-61540 (5617461540) shim plate ensures correct geometry of pivot points, body mounts, and dump frame assemblies—areas where alignment is critical. Without proper shimming, uneven load distribution can lead to premature wear, excessive vibration and reduced service life of bearings and supports.
Compatible with models such as the 330M, HD785-3/5/7 and HD985-3/5, this shim plate helps support stable performance in mining, quarry and heavy haul applications.Routine inspection is advised—check for shifted plates, bending or corrosion—and replace when thickness or alignment is compromised.
Choosing the Komatsu 561-74-61540 (5617461540) shim plate means investing in precision assembly, reduced wear and increased longevity of structural components. For equipment owners of Komatsu HD785-series and HD985-series machines, this plate offers a reliable solution to maintain optimal alignment and performance under demanding conditions.
