Ingersoll dg21-42-4 Vane Pack

Product Description

The INGERSOLL dg21-42-4 is a replacement vane pack designed for use in Ingersoll Rand pneumatic power tools. Vane packs are the core rotating assembly inside air-powered tools, consisting of a set of sliding vanes that ride within the rotor cylinder to convert compressed air energy into rotational output. When vanes wear, crack, or chip, tool performance drops noticeably — reduced speed, loss of torque, or complete failure to run. Replacing the vane pack restores the tool to proper operating condition without requiring a full motor rebuild or tool replacement.

This part is used in the service and repair of Ingersoll Rand pneumatic tools. Vane pack replacement is a routine maintenance task performed by tool repair technicians, industrial maintenance personnel, and authorized service centers. The reference number 03630688 may appear on service documentation, parts breakdowns, or the original tool packaging and can be used to cross-reference this component.

Key Features

• Direct replacement vane pack for Ingersoll Rand pneumatic tool service

Compatibility

Designed as an OEM-style replacement vane pack for compatible Ingersoll Rand pneumatic power tools. Refer to the Ingersoll Rand parts breakdown for your specific tool model to confirm fitment before ordering.

Installation Notes

Vane pack replacement is performed by qualified tool repair technicians familiar with pneumatic motor disassembly. Disconnect the air supply line and depressurize the tool completely before beginning any service work. Handle vanes carefully during installation — vanes are precision-ground components and should not be forced, mixed in orientation, or installed with contaminated surfaces. Refer to the applicable Ingersoll Rand service manual for disassembly sequence and rotor clearance guidance.
