The M20137 Gear Case Accessory Drive Bushing Remover & Installer (Front of Case) is a precision OEM-reference service tool specifically engineered for servicing accessory drive bushings located at the front section of the gear case on Cummins N14 diesel engines. This tool is designed to provide controlled, damage-free removal and accurate installation of bushings in one of the most critical alignment areas of the accessory drive system.
The front of the gear case supports key rotating components that transfer power from the engine to auxiliary systems. Bushings in this location are subjected to constant load, vibration, and lubrication demands. Over time, wear can lead to shaft play, gear misalignment, increased noise, and accelerated component wear. The M20137 addresses these issues by enabling precise service without compromising the integrity of the gear case housing.
During removal, the tool applies even, centered force to extract the worn bushing cleanly from the bore, eliminating the risk of scoring or distortion. During installation, it ensures the replacement bushing is pressed in squarely and to the correct depth, maintaining proper shaft alignment and oil clearance—both critical for long-term durability.
Its front-of-case-specific configuration ensures proper reach and alignment in confined working conditions, where incorrect tooling can easily cause damage. By replicating OEM service procedures, the M20137 provides technicians with a reliable, repeatable method for servicing this critical component.
Manufactured from high-strength, precision-machined materials, the tool is built for repeated use in heavy-duty diesel repair environments and is an essential addition to any Cummins N14 service toolkit.

Why It Matters
The front gear case area is critical for maintaining proper gear alignment and accessory drive performance. Worn bushings in this location can quickly lead to excessive wear, noise, oil leakage, and potential failure of connected components.
Improper servicing methods can damage the gear case housing—turning a routine repair into a major expense. The M20137 ensures precise, damage-free service, restoring proper alignment and extending the life of the accessory drive system. For technicians, this means reduced downtime, improved repair quality, and long-term reliability.
