install the collar assembly - Part ii
c. hold it, bolt it
Remove the rubber seal from the front of the collar assembly, if necessary, to fully access the mounting holes. Place the
ISCG spacer(s) onto the back of the collar assembly and align all of the mounting holes. Insert the three mounting bolts
through the collar assembly and ISCG spacer(s) to hold everything together. Carefully slide the complete assembly over
the drive side spindle. Align the mounting bolts to the mating ISCG tabs and hand start each bolt. Gently push the as -
sembly on so it sits flat against the ISCG tabs. Use a 4 mm hex to tighten all three mounting bolts in an alternating fashion.
Torque each bolt to 4.5 N·m (40 in-lb).
d. catch and release
You can check for proper collar assembly installation by sliding the anchor bolt on the collar assembly back and forth in the
seal disk window. You should see the pawls in the collar assembly extend to ‘catch’ and retract to ‘release’; there should be
no binding of the actuator. If you removed the rubber seal from the front of the collar assembly, slide the anchor bolt so the
pawls are retracted, and re-install the rubber seal, lip side down. Make sure it is fully seated and check again that the pawls
can extend and retract without interference.
install hammerschmidt front shifter
A. Install your Hammerschmidt shifter onto your handlebar in a position that is right for you. Use a 5 mm hex to tighten the
shifter clamp bolt and torque to 2.5-4 N·m (22-35 in-lb).
B. Turn the shifter adjuster barrel clockwise until it stops, then turn the adjuster barrel counter-clockwise one full turn.
C. Measure the amount of cable housing you will need to route the housing from the shifter into the cable stop on the collar
assembly. Cut the housing with the cable cutters. Remember, measure twice, cut once!
D. Feed the cable through the cable housing and route the housing from the shifter into the cable stop. Make sure the hous -
ing has a slight bend as it reaches the collar assembly and fits easily into the cable stop.
E. Press the small shifter paddle to ensure the cable is fully released. Loosen the cable anchor bolt, pull the shifter cable
taut and attach it to the actuator making sure the cable is sitting in the groove of the anchor bolt. Keeping the shifter
cable pulled taught, use a 4 mm hex to tighten the anchor bolt to 2.2 N·m (20 in-lb). Cut the cable a couple centimeters
past the anchor bolt and install a cable tip.
F. Slowly turn the HammerSchmidt shifter barrel adjuster counter-clockwise until you see the
anchor bolt move slightly to take up any cable slack. There should be a small gap between
the anchor bolt and the edge of the seal disk window.
install hammerschmidt drive mechanism and crank arm
Press the large shifter paddle to pull the actuator and retract the pawls on the collar assembly. Apply grease to the drive
side bottom bracket splines and crank bolt threads. Use an 8 mm hex to install the drive side crank arm assembly, making
sure the spindle splines engage with the bottom bracket. Tighten the crank bolt until it stops, and torque to 48-54 N·m
(425-478 in-lb).
