Product Details
The 172-9389 / 10R-4332 Remanufactured MAC 14 Electronic Control Group (Basic) is a direct replacement drive train controller, fits for Caterpillar wheel loaders, track-type tractors, motor graders, wheel dozers, compactors and underground loaders.
This MAC 14 controller is the basic hardware platform used in the drive train position across a wide range of machines; its role on each machine is set by the software flashed into it. Each remanufactured unit is disassembled, inspected and restored to the published 172-9389 part-number specification, then powered up on the bench and function-tested for power-up, data link communication and input/output response before dispatch.

Free Programming Before Dispatch — Information Needed After Purchase: This controller must be programmed to match your specific machine before it will operate correctly. We program it free of charge before dispatch, so it arrives ready to install. After placing your order, please send us:
- Machine serial number / VIN
- Engine Serial Number (ESN)
- Optional: photos of your current controller label and machine data plate to help us confirm fitment
Installation Notes: Installation and removal of the controller should be carried out by an experienced technician. Park the machine on level ground, lower all implements, engage the parking brake, turn the key off and disconnect the batteries before unplugging the controller. After installation, verify drive train operation and calibrations with a service tool before returning the machine to work.
