bearing cup assemblies. Using a high quality
National Lubricating Grease Institute E. P.
Grade 2 lubricating grease, wipe each
bearing cup assembly with grease. Fill all
cavities between the needle rollers. Also
apply a liberal coating of grease on the
bottom of each bearing cup assembly and

Caution - Spicer DOES NOT recommend
wiping the outside of bearing cup assemblies
or yoke cross holes with grease, oil or
silicone-based sprays. This could result in
bearing cup assembly rotation in yokes.
2. Position the journal cross into the yoke
cross holes with the grease zerk fitting
inward toward tubing. The double-headed,
grease zerk (nipple) fitting should be
perpendicular to the yoke cross holes.
Note: Failure to properly
universal joint will result in the inability to
grease the universal joint.

Note: Always inspect bearing cups for rollers
that may have fallen (downed rollers) out of
place before installation.
3. Move one end of the journal cross to
cause a trunnion to project through the cross
hole beyond the outer machined face of the
yoke ear. Take one bearing cup assembly
and position an installation height tool on the
end of the bearing cup assembly. Place the
bearing cup assembly over the protruding
trunnion diameter and align it to the yoke
cross.
