(Photo 8/35) Remove two bolts.
Take a
3/8" open end wrench and remove the
three screws from the end cap-see Photo 8/36.
Then,
tap the cap off the end of the transmission
gently with a small hammer if necessary. You
should remove and replace the gasket (part
#1124)
on the rear bearing cap. To shim the play
out of the shaft, use the part #1224-1, #1224-2,
and #1224-3
shims-see Photo 8/37. These
shims have
the same inside diameter and come
in thicknesses of 0.010", 0.030", and 0.005".
You use various
combinations ot'these shims as
required to take the play out of the main drive
shaft without putting undue pressure on the
bearing.
Replace
the end cap (see Photo 8/38) and
hold it in position with your left hand while you
hit the front of the drive shaft with a sharp blow
from a rubber mallet-see Photo 8/39. Then try
to move the drive shaft back and forth with
your right hand.
When you have
shimmed the bearing from
the rear, and replaced the cap, pull the drive
shaft back and forth from the front to deter-
mine if there is any play. Do this before you
have put the lower transmission pulley (see
page 136) on
the shaft. Remember, although
there should be almost no play in the shaft, it
cannot be so tight as to cause binding on the
bearing in the rear. This would heat up the
bearing and eventually do much damage. On
the
other hand, if it is too loose, that is not good
either. Being too loose will cause misalignment
that will wear out the worm and worm gear. It
might also loosen the rear cap during heavy til-
ling operations. Either case is potential damage
to the tilIer transmission.
