DISASSEMBLY
DISASSEMBLY - WITH SNAP RINGS
(1) Tap outside of bearing cap with a drift to
loosen snap ring.
(2) Remove snap rings (1) from both sides of yoke
(Fig. 17).
(3) Position yoke with the grease fitting if
equipped, pointing up.
(4) Position a socket with a inside diameter large
enough to receive the bearing cap, beneath the yoke
on a press.
(5) Place another socket with an outside diameter
smaller than bearing cap on the upper bearing cap
and press (1) the lower cap through the yoke (Fig.
18).
NOTE: If the bearing cap will not pull out of the
yoke by hand after pressing, tap the yoke ear near
the bearing cap to dislodge the cap.
(6) Pull bearing cap of the yoke.
(7) Turn yoke over in the press and straighten the
cross (1). Press the cross until the remaining bearing
cap (2) can be removed (Fig. 19).
CAUTION: If cross or bearing cap are not straight
during removal, the bearing cap will score the walls
of the yoke bore and damage can occur.
