Description
U.S. Army G-104 Spicer Tank Propeller-Shaft Sleeve-Yoke/U-Joint Assembly, G104-06-03195
The U.S. Army G-104 Spicer Tank Propeller-Shaft Sleeve-Yoke/U-Joint Assembly, identified by stock code G104-06-03195, is a driveline component for the M3/M4 medium-tank family. Its tag names the item Sleeve Yoke Assy and gives the Spicer reference SP-K5-3-348X.
Army technical documentation shows this propeller-shaft arrangement on the M3A3, M3A5, and M4A2. The G-104 association is broader than one Sherman variant, making the assembly relevant to both the M3 medium-tank and M4 Sherman driveline families.
Historical Significance
The G-104 supply group covered the U.S. Army's M3 and M4 medium-tank families, including vehicles associated with the Lee, Grant, and Sherman names. These tanks used propeller shafts to carry power forward through the hull from the engine and transfer equipment to the transmission and final-drive system.
War Department manual TM 9-1750G documents the propeller-shaft components used with the twin-diesel power plant in the M3A3, M3A5, and M4A2. Its illustrated breakdown identifies the sleeve yoke, universal-joint journal, bearing assemblies, flange yoke, and related slip-joint parts.
M3/M4 Medium-Tank Driveline Application
The documented assembly arrangement served the diesel-powered M3A3, M3A5, and M4A2 medium tanks. The M4A2 manual places the propeller-shaft slip joint directly behind the front universal joint.
The tag does not limit the offered assembly to a single Sherman subvariant, so its catalog identity remains the broader G-104 Spicer tank propeller-shaft sleeve-yoke/U-joint assembly.
What This Item Is and Does
The female-splined sleeve yoke accepted the splined end of the propeller-shaft tube. This sliding connection allowed the shaft assembly to change its effective length as installed components moved slightly in relation to one another.
The universal joint allowed the driveline to transmit rotary motion across an angular offset. The circular flange provided the bolted connection to the mating driveline companion flange. Together, these features formed the flexible slip-joint end of the tank's propeller shaft.

Why This Item Matters
Large tank driveline components show the mechanical systems that operated beneath the armor and connected the power plant to the front-mounted transmission. The visible Spicer construction, splined sleeve, universal joint, and flange make this assembly useful for studying the M3/M4 medium-tank power train.
It has strong value as a restoration reference, museum display component, teaching aid, or identifiable G-104 mechanical artifact. No serviceability or installation readiness is represented.
About This Item
The identification tag reads G104-06-03195, Sleeve Yoke Assy, SP-K5-3-348X, and 3/52 RIA. The assembly shown has an olive-drab finish, visible internal splines, a universal joint with Spicer-marked bearing caps, and a circular drilled flange.
The photographed assembly shows finish wear, scratches, grime or grease residue, and areas of surface oxidation, including along the flange edge and exposed spline area. Its operating condition has not been established, and it is offered as a historical driveline component and restoration reference.
