MW heavy-duty transmission yokes have been designed to incorporate Spicer® 1350 series U-joints and are forged from heat treated 4340 steel. All yokes are 100% machined in house on MW's state-of-the-art CNC machines. Special fixtures are used to guarantee that all machining is done in relationship to the spline pitch diameter. This assures concentricity and produces a yoke that is symmetrical and balanced for smooth operation. The yokes are then re-heat treated to over 200k PSI and U-joint cup bores are honed to exact limits and the bushing/seal surface is ground with special fixtures assuring concentricity with the spline pitch diameter. Like all MW product's they are laser engraved with part numbers and batch numbers that allow complete trace-ability. The end of spline sealing feature is an o-ring seal with a tapered retaining ring that forces an aluminum plug against the seal. This improved method has proven to eliminate fluid seepage.
