Dana Spicer 216938 Output Shaft Gear / Shaft Gear N1
The Dana Spicer 216938 Shaft Gear N1 is a genuine heavy-duty output shaft gear used in select Dana Spicer / Clark off-highway torque converter and powershift transmission assemblies. Designed for construction and industrial equipment, the 216938 transfers rotational power through the transmission output section and is engineered to withstand the high torque, shock loading, and continuous-duty operation associated with wheel loaders and other severe-service machinery.
Although some Dana/Spicer aftermarket catalogs describe 216938 as “SHAFT GEAR N1,” equipment parts manuals identify the component more specifically as an output shaft gear. It is used in conjunction with the transmission output shaft, front and rear output-shaft bearings, retaining rings, output flange, and related torque-converter components.

Parts references for the Clark C270 torque-converter family specifically list 216938 as an Output Shaft Gear, together with output shaft 214937, turbine shaft gears, pump-drive gears, stator components, impeller gears, and other converter components.
How the 216938 Gear Functions
The 216938 is positioned in the output section of the transmission or torque-converter assembly. As power passes from the engine through the torque converter and transmission gearing, the output gear helps transmit that torque to the output shaft, which ultimately delivers power into the vehicle’s driveline and drive axles.
A typical power path can be represented as:
Engine → Torque Converter → Transmission Geartrain → 216938 Output Shaft Gear → Output Shaft → Output Flange/Yoke → Driveshaft → Axle
Because the output gear operates under significant torsional loading, tooth geometry, shaft fit, bearing condition, and gear alignment are critical to reliable operation.
Related Components
Equipment manuals show the 216938 installed with components including:
- 214937 – Output Shaft
- 201951 – Output Flange Nut
- 743439 – Rear Output Shaft Bearing
- 223901 – Bearing Retaining Ring
- 235057 / 742056 – Front Output Shaft Bearing, depending on application
- 214955 – Bearing Retaining Ring
- 214940 / 214987 – Output Flange configurations
These surrounding components should be inspected whenever the output gear is being replaced, particularly the bearings and retaining hardware that establish proper shaft support and gear alignment.
Documented Equipment Applications
The Dana Spicer 216938 appears in parts documentation for older Clark/Michigan wheel loaders and related off-highway drivetrain systems. Published equipment manuals show it in machines such as the Michigan 75A Series II and Clark/Michigan 85A-series loaders. It is also listed among torque-converter components for Michigan 125C equipment using Clark C272/C273-family converter assemblies.
