Installation Procedures
Installation of New Main Shaft and Bearings
Use truing stand part reference chart for the following instructions.
1. Loosen set screws or cap screws located on both main shaft adjusting collars
#209-2. Collars should rotate freely on main shaft #211S. Uprights #201-2/200-
2 should now move at top when pushed left or right. On older stands it may be
necessary to remove collar set screw completely and lubricate hole to free
collars from main shaft.
2. Remove right side upright pivot bolt #225-2 and pull upright toward the right.
3. Turn knob #213S/215S clockwise to disengage main shaft from left side
threaded pivot bushing #204LS.
4. Pull knob #213S/215S to right and remove main shaft and right side upright
from stand. Remove old collars and spring.
5. Remove both knob #213S/215S and knob locknut #212S from main shaft.
6. Remove left side upright pivot bolt and remove left side upright from base.
7. Remove old bushings #232-2 from both uprights and install four new bushings
into uprights.
8. Grease both threaded pivot bushings on left and right side uprights. Use care
not to mix up bushing or arms. Left side bushing has left hand threads and
has yellow plating. Right side bushing has right hand threads. Grease pivoting
surface and outer faces of bushings.
9. Reinstall left side upright and pivot bolt back into base. Tighten bolt fully.
10. Grease threads of new main shaft #211S. Install main shaft through hole
in right side upright and into bushing. NOTE: Main shaft has both left and
right hand threads. Right hand threads go to right side upright and left hand
threads go to left side upright. Right side of main shaft has more threads than
left side.
11. Thread knob locknut onto right side of main shaft until 8 threads are exposed
(distance of 16mm.) Install knob #213S/215S and tighten against locknut.
12. Guide main shaft through right side of base.
13. The following parts will be installed on main shaft between short base
uprights: bearing washer #749-1, needle bearing #748-1, bearing washer
#749-1, main shaft adjusting collar #209-2, spring #229, main shaft adjusting
collar #209-2, bearing washer #749-1, needle bearing #748-1, bearing washer
#749-1. NOTE: It is necessary to compress the spring to install the left hand
set of collar, washers, and bearing.
14. Install right side upright into base. DO NOT attach right side pivot bolt at this
time.
15. Sight from left side of base to align threads of pivot bushing to threads of
main shaft. Grab main shaft to raise or lower as necessary. Rotate threaded
bushing as necessary to best align main shaft and bushing threads.
16. Push left bushing against end of main shaft. Maintain pressure against main
shaft and rotate knob counter-clockwise. If more than one rotation of knob
is required to engage main shaft into bushings, unthread main shaft and start
threading again.
17. Continue to thread knob counter-clockwise until main shaft just begins to
protrude out left side pivot bushing.
18. Install right side upright and pivot bolt into base. Tighten bolt fully.
19. Grab both uprights and move them side-to-side until they appear
approximately symmetrical.
Installation of Split Nylon Bushings #235-2 onto Caliper Arm
1. Loosen caliper adjusting knob #217S/216S until caliper arm #207-2 is nearly
vertical in order to relax tension in spring #206-2/210.
2. Unhook spring #206-2 from caliper arm.
3. Remove right side caliper locknut #233-2, washer #234-2/749-1, and old
bushing #235-2.
4. Install new bushing #235-2.
5. Reinstall washer and nut on right side and tighten.
6. Remove left side caliper locknut and washer. Remove old bushing and install
new bushing #235-2.
7. Reinstall washer and nut on left side and tighten.
8. Check adjustment of caliper arm. Locknuts should be as snug as possible but
still allow the caliper arm to freely move up and down.
9. Raise caliper arm again to vertical position and reinstall spring.
10. Lower caliper to working height of rim and tighten caliper
adjusting knob #217S/216S.
Centering Adjustment of the TS-2/TS-2.2 Truing Stand
1. Sight down the front of the stand. The top edge of the
caliper mounting plate must be parallel to the main shaft.
If it isn’t, place a large adjustable wrench across the plate and twist as
necessary to bring it into alignment.
2. Either the #1554-1 Centering Gauge or a dished wheel is needed to determine
if the wheel is centered in the stand. If using a wheel, use a dishing tool, such
as the Park Tool WAG-4 or WAG-5, to determine the accuracy of the wheel.
3. Place the wheel or Centering Gauge in the stand and rotate the upright
adjustment knob just until the uprights touch the locknuts on the hub. DO NOT
FORCE UPRIGHTS INTO HUB LOCKNUTS BY OVERTIGHTING KNOB.
4. Measure the distance between the left edge of the rim or gauge and the left
base upright, as well as the distance between the right edge of the rim or
gauge and the right base upright. If the measurements are different, gently
tap the uprights sideways until the measurements are equal on both sides.
Tighten the cap screws in the shaft adjusting collars.
5. Remove wheel and check side-to-side play of uprights. Shaft adjusting
collars and bearings should be fully against base. There should be little or no
play in uprights.
6. Reinstall wheel. Readjust collars only if there is excessive play in uprights.
7. Rotate the caliper arm adjusting knob to raise the calipers close to rim. Open
or close the calipers as necessary using the caliper adjusting knob to check
that the rim is centered between the two calipers. If the rim is not centered,
loosen the caliper arm nut #233-2 on one end of the caliper arm pivot shaft
and tighten the opposite nut an equal amount. This will shift the entire caliper
arm assembly toward the side that was tightened. Continue until rim is
centered between the calipers. For example, if there is a gap between rim/
gauge at left side caliper, loosen left caliper nut #233-2 and tighten right side
caliper nut. This moves the entire caliper arm mechanism to the right.
8. Double check the caliper arm for free motion. Over tightening caliper shaft
nuts will bind caliper arm.
NOTE:
While the TS-2 and TS-2.2 are designed to provide automatic dishing of
the wheel, imperfections in the shape or condition of the axle or locknuts can
affect the dish reading, as the imperfection is magnified significantly by the
distance from the hub to the rim, where the actual reading is taken. As a result,
for precision work, a dishing tool such as the Park Tool WAG-4 or WAG-5 should
be used to verify final adjustments.
Installing Caliper Springs #222-SR and #222-SL
NOTE:
Test caliper springs by moving caliper outward and releasing. If spring is
not fatigued, save replacement springs #222-SR and #222-SL for future use. Note
that right side spring #222-SR coils counter-clockwise, and left side spring #222-
SL coils clockwise.
1. Use tape or other mark on right side caliper to distinguish it from left side.
2. Loosen caliper adjusting knob #224S/223S until shaft is nearly removed from
caliper arm.
3. Remove left side caliper locknut #226-2, caliper spacer #228-2R and
spring #222-SL.
4. Remove right side caliper locknut #226-2, caliper spacer #228-2R and spring
#222-SR.
5. Install spacer #228-2R and spring #222-SR onto right side of caliper bracket.
Engage spring into hole in caliper bracket.
6. Install right side caliper onto caliper bolt by tilting spring top downward and
manipulating spring end into caliper. Next manipulate caliper and spring over
spacer and onto the stud. Install and tighten locknut. Use care not to pinch
spring coils between spacer and caliper.
7. Install left side spring, spacer and caliper using similar technique.
8. Check adjustment of caliper locknuts. Snug locknuts but do not over tighten.
Pull back slightly on each caliper and release. If arm does not freely return,
locknut is overly tight.
9. Tighten caliper adjusting knob #224S/223S until caliper opens up to working
position.
10. Double check centering of TS-2/TS-2.2 and adjust as necessary using
Centering Adjustments of the TS-2/TS-2.2 described above.
