Detailed Description

The 2V7390 SHIM PACK CATERPILLAR is designed for precision. Used in critical assemblies within Caterpillar machines, this shim pack allows technicians to dial in the exact clearance or preload needed between gearsets, shafts, and other load-bearing components. Its design features an evenly spaced 8-hole bolt pattern, allowing secure installation in circular flanges and housings.

Unlike single shims, shim packs include a set of washers in varying thicknesses, allowing custom spacing adjustments depending on wear conditions or service requirements. These thin metal spacers play a massive role in mechanical efficiency and structural integrity. A proper shim pack ensures that components are neither too tight (causing friction and overheating) nor too loose (resulting in misalignment or noise).

Engineered from hardened steel, the 2V7390 SHIM PACK CATERPILLAR resists deformation under pressure and provides long-term reliability even in high-vibration environments such as swing frames, gear housings, and transmission interfaces.

Role in Heavy Machinery Systems

The 2V7390 SHIM PACK CATERPILLAR serves a simple but essential function: to keep machines running smoothly by controlling clearances. In high-load Caterpillar machines, maintaining the correct spacing between parts like gears, shafts, or bearings is critical. A fraction of a millimeter can be the difference between optimal performance and serious damage.

Here’s how this shim pack contributes to machinery longevity and performance:

• Alignment Assurance: Ensures rotating components like shafts or gears are positioned correctly, avoiding uneven loading.

• Preload Adjustment: Allows operators to fine-tune the preload on bearings, ensuring they function correctly without excessive resistance.

• Compensation for Wear: Bridges gaps that occur from part wear over time, restoring factory-set tolerances.

• Reduced Vibration: Minimizes mechanical play, reducing noise and improving system stability.

• Extended Component Life: Prevents direct metal-to-metal contact that leads to premature part wear.

Every 2V7390 shim is engineered with strict tolerances, making it an indispensable tool for field service and machine rebuild teams.

Maintenance and Replacement

Although shims do not bear direct rotational loads, they are still subject to wear and compression—especially during reassembly after maintenance or rebuilds. Over time, corrosion, heat cycling, or impact can alter their thickness or integrity.

Signs the 2V7390 shim pack may need inspection or replacement:

• Excessive play in gears or shafts

• Abnormal vibration or noise

• Evidence of shim warping or cracking

• Corrosion or wear marks on the washer face

• Misalignment of shaft centers or gear meshing

Installing the 2V7390 SHIM PACK CATERPILLAR is quick and requires no special tools. Always ensure mating surfaces are clean and bolts are torqued to specification during installation. Technicians often use feeler gauges to confirm the correct gap has been achieved.

With 3GEN Export, replacement shim packs are just 5 working days away—no matter where you are in the world.
