f.
Repeat this procedure on the remaining bearing assemblies to remove the cross from the shaft yoke (4 or 6).
NOTE
If driveshaft is to be separated make corresponding marks on yokes (4 and 6) so that these
will be properly alined at assembly.
g.
If parts replacement is required, unscrew dust cap (7) and remove sleeve yoke (4), washer (8) and cork washer
(9).
4-6.6.3 Assembly. At assembly use all new parts of journal and bearing kits (items 2, 3 and 5) and shaft dust cap kit
(items 7, 8 and 9).
a.
Slide dust cap (7), washer (8) and cork washer (9) over shaft of yoke (6).
b.
Position sleeve yoke (4) so that alignment marks of both yokes (4 and 6) are on same side, then slide sleeve
yoke onto shaft and screw dust cap (7) onto sleeve yoke.
c.
Pack the four grease cavities of the cross (5) with a high quality extreme pressure N. L. G. I. Grade 1 or 2
grease. Also pack each bearing assembly (3) approximately 1/4 full with this grease.
d.
Position the cross (5) in the yoke (4 or 6) with its lube fitting on the inboard side (toward driveshaft).
e.
Move one end of the cross (5) to cause a trunnion to project through the cross hole beyond the outer machined
face of the yoke lug. Place a bearing assembly (3) over the trunnion diameter and align it to the cross hole.
Using an arbor press, hold the trunnion in alignment with the cross hole and place a solid plug on the upper
bearing assembly. Press the bearing assembly into the cross hole enough to install a snap ring (2).
f.
Repeat e. for opposite bearing, then again for flange yoke (1).
g.
Repeat steps c. through e. for opposite end of driveshaft.
4-6.6.4 Installation. Attach the flange yokes (1) to the driving and driven components with proper attaching hardware.
Torque screws to 40-48 lb-ft.
