9951-71 -- Cap & Width Specifications

The it specs: 1.102" cap dia | 2.787" width. Cap diameter determines which yoke bore it fits -- the cap must seat fully into the yoke without play. Bearing width (2.787" across the body) controls the span between yoke ears. A cross that is too wide won't fit; too narrow and the snap rings don't seat in the groove. Amphicar Axle Joints.

Verify the yoke bore diameter against the this unit cap size before installing. The snap ring style (outside snap ring retention) must match the yoke groove pattern -- OSR yokes have an external groove; ISR yokes have an internal groove. The the assembly is factory-sealed -- no maintenance interval, no grease fitting. Correct installation torque on the strap kit or U-bolt is critical -- undertorqued straps allow the cap to walk under load.

Installation Notes for this u-joint

Before installing the it, clean the yoke bores of any rust, burrs, or old bearing material. The bearing cups must drop in by hand -- never drive them in with a hammer directly on the cup. Use a proper cross-and-bearing installation tool or a press. Driving a cup in at an angle cocks the needle bearings and destroys the the part before it ever sees load.

After installation, verify full rotation without binding. A binding cross indicates a cup is cocked or seated too deep. The this component should articulate freely through the full operating angle of your driveshaft before the vehicle is lowered off the lift.
