TS-25 Repair Stand Mounted Wheel Truing Stand
• Fits all Park Tool PRS-25 Repair Stands, as well as PCS-10, PCS-4 and
PCS-1 Repair Stands manufactured after 2003 (identified by 37mm
upright tube diameter)
• Works with 16" to 29" wheels
• Easy to install and use
INSTALLATION
1. Remove the two socket head cap screws on the back of the repair stand's
top tube assembly using 4mm hex wrench. Save nuts for reuse.
2. Mount wheel bracket (#12) on left side of top tube assembly using 30mm
socket head cap screws (#13) and nuts.
3. Install gauge (#7) and gauge spacer (#9) onto collar assembly (#1 and #2)
using knob and shaft (#10) and nut (#8).
4. Using quick release lever (#11), mount collar assembly onto upright tube
of repair stand. NOTE: The TS-25 includes an upright adapter sleeve
(#3) for adapting the hex-shaped collar assembly to the round upright
tubes on PCS-1, PCS-4 and PCS-10 Repair Stands. The PRS-25 Repair
Stand uses a hex-shaped upright tube and does not require the use of the
adapter sleeve.
SET UP
1. Inspect rim for cracks, bulges, and dents. Check for broken or loose
spokes, and for nipples that may be rounded or rusted. Make sure hub is
adjusted properly and axle is not bent. Repair or replace parts as needed.
2. Lubricate each nipple if necessary. Clean excess lubricant from wheel.
3. Use a spoke wrench properly sized to fit the wheel's spoke nipples. Park
Tool Professional Quality Spoke Wrenches are recommended.
LATERAL TRUING BASICS: CORRECTING SIDE TO SIDE ERRORS
1. Remove tire (if desired). Place wheel into "V" notch of wheel bracket and
lock with wheel's quick release or axle nut. Lever of quick release should
be positioned on the side of the wheel bracket.
2. Position tip of gauge to sidewall of rim. Spin wheel slowly and look for
side to side wobbles. Locate largest wobble.
3. If rim wobbles to the right, tighten left side nipples within area of wobble
1/4 turn. If rim wobbles to the left, tighten right side nipples within area
of wobble 1/4 turn. Spin wheel and note impact. Repeat as needed to
remove wobble. Note: If further tightening could cause nipple damage
or create uneven spoke tension, similar results can be achieved by
loosening the opposite side nipples 1/4 turn within area of wobble (for
example, if rim wobbles to the right, loosen right side nipples within area
of wobble).
4. Repeat procedure on other wobbles until wheel runs straight.
RADIAL TRUING BASICS: CORRECTING ROUNDNESS ERRORS
1. Remove tire. Place wheel into "V" notch of wheel bracket and lock
with wheel's quick release or axle nut. Lever of quick release should be
positioned on the side of the wheel bracket.
2. Position gauge to rest just under outside edge of rim. Spin wheel slowly
and look for areas where rim moves toward gauge (high spot) or dips
away from gauge (low spot).
3. If rim has a high spot, it needs to be pulled away from the gauge. Tighten
nipples within area of high spot 1/4 turn. Check result and repeat as
needed until high spot is removed.
4. If rim has a low spot, it needs to be pushed toward the gauge. Loosen
nipples within area of low spot 1/4 turn. Check result and repeat as
needed until low spot is removed.
5. Adjustments made to correct high and low spots may have affected lateral
true of wheel. Re-true as needed until wheel is both straight and round.

PRE-STRESSING: RELIEVING SPOKE WIND-UP
After truing, spokes should be pre-stressed in order to relieve spoke wind-up
that occurs as nipples are turned. To pre-stress, tightly squeeze parallel pairs
of spokes all the way around wheel. This may cause wheel to go slightly out
of true. If so, re-true as needed.
WHEEL DISHING: CENTERING RIM BETWEEN HUB LOCKNUTS
For a wheel to perform properly, it is important for the rim to be centered
between the locknuts of the hub. When the rim is centered, a wheel is
properly "dished". To check this, and to make precision adjustments, a wheel
dishing gauge such as the Park Tool WAG-4 or WAG-5 is recommended.
To avoid damage, remove TS-25 from repair stand before folding for storage
or transport. For more information and for detailed wheel truing instructions
