Park Tool Co. 5115 Hadley Ave. N., St. Paul, MN 55128 (USA) www.parktool.com
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
a. 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.
b. Mount wheel bracket (#12) on left side of top tube assem-
bly using 30mm socket head cap screws (#13) and nuts.
c. Install gauge (#7) and gauge spacer (#9) onto collar as-
sembly (#1 and #2) using knob and shaft (#10) and nut (#8).
d. 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
a. 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.
b. Lubricate each nipple if necessary. Clean excess
lubricant from wheel.
c. 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
a. 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 posi-
tioned on the side of the wheel bracket.
b. Position tip of gauge to sidewall of rim. Spin wheel slowly
and look for side to side wobbles. Locate largest wobble.
c. 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 loosen-
ing 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).
d. Repeat procedure on other wobbles until wheel runs straight.
RADIAL TRUING BASICS: CORRECTING ROUNDNESS ERRORS
a. 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.
b. 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).
c. 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.
d. 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.
e. 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 fold-
ing for storage or transport.

Vergewissern Sie sich, dass das Nabenspiel richtig
eingestellt und die Achse nicht verbogen ist. Repari-
eren oder ersetzen Sie bei Bedarf defekte Teile.
