4.
Remove snap ring from yoke. Turn U-joint over and remove opposite snap
ring.
5.
Set the yoke in an arbor press with a piece of tube stock beneath it. Position
the yoke with the lube fitting pointing up to prevent interference during
disassembly. Place a solid plug on the upper bearing assembly and press it
through to release the lower bearing assembly.
6.
If the bearing assembly will not pull out by hand after pressing, tap the base
of the lug near the bearing assembly to dislodge it.
7.
To remove the opposite bearing assembly, turn the yoke over and straighten
the cross in the open crosshole. Then carefully press on the end of the cross
so the remaining bearing assembly moves straight out of the bearing
crosshole. If the cross or bearing assembly is cocked, the bearing assembly
will score the walls of the crosshole and ruin the yoke.
8.
Repeat this procedure on the remaining bearing assemblies to remove the
cross from the yoke.
9.
After removing the cross and bearings (both ends), inspect all yoke lug
crosshole surfaces for damage or raised metal. Raised metal can be removed
with a rattail or half-round file and emery cloth. Check the yoke lug
crossholes with a Go/No-Go Wear Gauge, and then use an alignment bar to
inspect for damage by sliding through both crossholes simultaneously. The
alignment bar will identify yoke lugs that have taken a set because of
excessive torque. Raised metal or distorted lugs can cause premature cross
and bearing problems.
10.
Clean the crossholes of the inner and outer yoke ends used to attach the
Gear Motor and Capstan Drive Fitting and inspect with an alignment bar (as
described above). If after proper cleaning of the crossholes the alignment bar
will not pass through simultaneously, the yoke lugs are distorted and the
yoke or yokes should be replaced.
Also inspect the inner yoke's 1-7/8" bore and
the outer yoke's 1-1/4" square drive. Loose
fitting or worn (inner yoke "out-of-round";
outer yoke "rounded corners") yokes can cause
serious injury.
