the gear lash measurement is within speci-
fication. You must proceed slowly, how-
ever, so the collapsible collar will not be
damaged. If you tighten the securing nut
so that gear lash is less than 0.1 mm
(0.004 in), you will have to disassemble
the middle driven shaft and replace the
collapsible collar.
CAUTION:
Never loosen the securing nut when adjusting gear
lash. There will be insufficient pressure on the col-
lapsible collar. Gear lash adjustment must be com-
pleted within five minutes, otherwise, the Loctite®
will harden and inhibit gear lash adjustment.

securing nut.
12. Place the yoke into the u-joint.
13. Grease the bearings, and insert them onto
the yoke.
CAUTION:
Check each bearing. The needles can easily fall
out of their races. Slide the yoke back and forth
in the bearings. The yoke will not go all the way
into a bearing if a needle is out of place.
14. Press the bearings into the u-joint with a
vise.
NOTE:
It may be helpful to tap the u-joint with a drift
punch.
15. Using a suitable socket/further press each
bearing into the u-joint until the retainer can
be installed onto each bearing. The retainer
fits in the slot on each bearing.
