Rebuilt Mack Transfer Case
Rebuilt Mack TC15 and TC25 series transfer cases, and how to read the identification stamping on your unit before you call.
We supply new and rebuilt Mack transfer cases, single speed and two speed, and the replacement parts and overhaul kits for every model we rebuild. A rebuilt unit is torn down, cleaned and inspected in our Orlando shop, the worn parts are replaced, and it is checked before it ships. One call gets it quoted and on its way, in the United States or overseas.
Identify your Mack transfer case
The model code is stamped on the rear end plate of the transfer case, just to the right of the countershaft rear bearing cover.
The stamping carries four pieces of information:
- 1. Unit symbol. For example TC2520: TC = transfer case, 25 = family or series, 2 = front to rear drive ratio, 0 = high and low range ratios.
- 2. Transfer case serial number.
- 3. Transfer case assembly (part) number. Some digits vary.
- 4. Options, such as a PTO or an oil pump.
Read us the unit symbol and the serial number and we can match the unit and its parts. The high, low and front drive ratio behind each unit symbol is in the Mack gear ratio chart.
