Overhaul and adjustment of ShimanoŽ SPD pedals
Level of Difficulty: Intermediate
This article will discuss the bearing service of the common ShimanoŽ
SPD type pedals. You will need a pedal spanner to remove the pedals, such
as the Park Tool PW-3,
PW-4, or HCW , but disassembly of the bearings requires special tools
Typical Tools and Supplies Needed
- Pedal Wrench
- ShimanoŽ TL-PD-40 bearing shaft removal tool
- ShimanoŽ TL-PD-73 bearing adjustment tool for some models
- 10mm thin open end wrench
- 7mm box end wrench or small adjustable wrench
- Axle and pedal vise
- Compressed air and blow gun (optional)
Keep in mind that you do not need to take apart the SPD pedal shaft unit
to clean and grease the unit. Here is a simple overhaul procedure for
ShimanoŽ pedal shaft units.
1 Remove both pedals from bike. For help, see
Use soft jaws in vise or pad jaws with rag to hold pedal. Engage ShimanoŽ
PD-40 tool onto shaft unit if necessary. Some recent Shimano pedals such
as the PD-7750 and PD-M959 have spanner flats on the outside of the pedal
axle unit, so a suitable spanner is used instead.
Service and reassemble one pedal at a time. Left pedal has a right
hand-threaded shaft unit, remove unit counter-clockwise. Right pedal has
a left hand-threaded shaft unit, remove unit clockwise.
4 Clean and scrub both body and shaft in solvent. Blow dry with
a compressor. Wipe off and allow to dry completely if you don't have a
Fill bottom forth of shaft unit hole in body with grease. Shaft unit is
a press fit inside body, so when you install unit, new grease is forced
inside bearings of shaft unit.
6 Use ShimanoŽ TL-PD-40 to thread shaft unit into pedal body.
THERE IS NO TORQUE, THREAD UNTIL UNIT IS FULLY INSTALLED THEN STOP.
7 Use a drop of light lubricant on body springs and pivot points.
Check screws for tightness.
9 Grease axle threads and reinstall pedals. Secure each pedal
to 360 inch-pounds.
bearings may be adjusted. Some models require a 7mm wrench for the locknut
and a 10mm wrench for the adjusting cone. However, some models have the
locknut recessed and require a tool from ShimanoŽ, the TL- PD-73. This
double socket tool holds the adjusting cone and loosens the locknut. The
inner socket of the PD-73 is double sided, one is a 7mm, the other is
8mm, and this is used to secure or loosen the locknut. The outer portion
is also double sided, with a 10mm and 11mm option, and it is used to move
The threads of the adjusting cone and locknut are right hand-threaded
on both left and right pedals. Hold shaft unit secure by holding pedal
thread in soft jaws of a vise. Use the Park Tool
AV-3 axle vise for this. If you don't have a vise, re-mount pedal
in crank to hold it secure.
test bearing adjustment, grab cylinder section of shaft unit, not plastic
section. Bearing adjustment only effects cylinder section. Play in plastic
section will disappear when unit is remounted in pedal body. To adjust,
hold cone with 10mm wrench CBW-1 and loosen counter-clockwise locknut
with 7mm wrench.
To tighten bearing adjustment, turn cone clockwise a very small amount,
and re-secure locknut. Check again for play, and repeat as necessary,
making adjustments in small increments. After adjustment is finished,
re-install shaft unit into pedal body as described above.
