S5-42 8-Tooth Speedometer Drive Gear

The Zumbrota Drivetrain S5-42 is a remanufactured 5-speed manual transmission engineered for 1987-1992 Ford F-series trucks featuring the 6.9L or 7.3L diesel engines. This transmission is specifically designed for 2WD models and includes an 8-tooth speedometer drive gear, making it suitable for applications where a Power Take-Off (PTO) unit is in use. The S5-42 transmission is ZF built and features front and rear cases with an integral bell housing. Zumbrota Drivetrain emphasizes quality in its remanufacturing process, with units subjected to a rigorous three-stage inspection. This includes a pre-inspection to identify and address case cracks or excessive wear, a mid-process inspection to ensure all components meet OEM specifications, and a final post-build inspection to verify adherence to strict standards. Every internal part, including gears, mainshaft, and synchronizers, undergoes 100% inspection. To guarantee performance and reliability, all transmissions are dyno tested and run through various real-life scenarios before shipment. This transmission offers a gear ratio of 4.14 for low range and 0.77 for high range, providing a balance between pulling power and highway cruising efficiency. The ID codes associated with this unit include 1307-050-035, 1307-050-038, 1307-050-057, E8TA-ARA, E8US-AB, E9TA-YZ, and E9TA-ZA, with Hollander numbers 400-02275A and 400-02276A.
