K. PROCEDURE FOR ELIMINATING CREEP IN VSD SHIFTER
I. Referring to drawing (101-218-201) variable speed drive sandwich assembly, lower right hand drawing at
the extreme top of the head you will notice four 10/32 x 7/8 button head screws which hold the (111-218-
002) shift lever assembly to the (111-218-003) cam housing.
These four screws keep enough tension on the 1056-004-451) cup washers to provide the proper friction
between the shift lever and the housing to prevent creeping.
This creeping is easily remedied by tightening these four button head screws.
L. METHOD OF CHANGING PRESENT SPIN DLE FOR OLDER TYPES WITH 2968, 2969, AND 2970 SPACERS
1. Remove N-07 lock nut from top of spindle.
2. Loosen 10/32 lock screw from bottom of quill.
3. Remove 2972 quill nut by turning counter clockwise.
4. Tap splined end of spindle on block of hard wood and spindle and two lower bearings will come out.
5. Discard spacer 2968.
6. Put 200-039 spacer on splined end of spindle against the thrust bearings of new spindle.
7. Press entire assembly in quill and install quill nut.
8. Install snap ring on top of spindle.
9. If old spindle bearings are used, discard spacers 2969 and 2970.
M. PROCEDURE FOR CHANGING BRAKE SHOES ON VARIABLE SPEED HEAD ASSEMBLY
1. With spindle motor running shift spindle speed to highest RPM then remove spindle motor as described in
2. Referring to drawing 101-218-201 in the service manual remove the 111-218-002 speed shift lever by
removing the four (4) socket head cap screws which hold it against the 111-218-205 ring.
3. Remove the six (6) 1/4 20 x 3/4 socket heads which hold the 111-218-003 cam housing to the pulley guard
and remove housing from pulley guard.
4. Now by reaching through the holes in the sides of the pulley guard, the lower pulley sleeve can be worked
up out of the pulley guard casting, thus exposing the brake shoes.
5. Now the 3/8 x 3-1/4 roll pins can be driven in to clear the brake shoes. (Note: The pins must be driven all
the way to clear the pulley guard casting and fall free.)
6. Unscrew the 111-218-204 brake pull rod and remove old shoes.
7. Reassemble in reverse order making sure the 056-009-636 cog belt is around the drive hub. This is made
simpler if the cog hub is slowly rotated while being pushed or tapped down into its proper position.
8. After reassembly is completed, the shoes can be properly adjusted by first tightening the 1/4 20 x 1-1/4
socket set screw above the brake handle until the shoe makes contact with the outer race of the pulley and
then backing off to just clear. Then the 111-218-004 brake pull rod should be turned clock wise until
contact is made with the inner pulley race and then backed off to clear.
