CHAPTER THREE
Inspection, Adjustment & Lubrication
with your hand. If you feel any looseness or
roughness in the pedal bearings, have your
pedal adjusted, re-greased, or replaced by your
Gary Fisher dealer.
Every 3 months
inspect the crankset, check
the bottom bracket adjustment, and tighten the
crank bolts:
• Crank bolts
-single 6 or 8mm bolt on each arm: 350-435 lb•in (39.5-
-single 6 or 8mm bolt on each arm: 350-435 lb•in (39.5-
49.2 Nm)
-double pinch bolts on each arm (Figure 3.3.3) : 88-132
Lb•in (10-15 Nm)
• Chainring bolts: 70-95 lb•in (7.9-10.7 Nm)
To check the bottom bracket bearing adjustment
1. Lift the chain from the chainrings.
2. Rotate the crank so that one of the arms is parallel the seat tube.
3. Put one hand on the crank arm and one hand on the seat
2. Rotate the crank so that one of the arms is parallel the seat tube.
3. Put one hand on the crank arm and one hand on the seat
tube, and attempt to move the crank arm laterally toward
and away from the seat tube.
4. Spin the cranks.
If the crank feels or sounds loose, or if the motion stops
abruptly or you hear a grinding noise coming from the
bearings, the bearings need to be adjusted or re-greased by
your Gary Fisher dealer.
Clean the chainrings and inspect them for
damage. If any teeth are bent or broken, have the
chainring replaced by your Gary Fisher dealer.
Note that on some chainrings, a few teeth have a
special shape to enhance shifting.
Every 3 months
check your chain for wear with
a chain wear gauge or a ruler. Each full link of a
new chain measures one inch. If 12 links of your
chain measures 121/8 inches or more, it should be
replaced. With good maintenance, a chain usually
lasts 1000 to 1500 miles on a road bike, less on a
mountain bike. Replacing the chain takes special
tools and training and should only be done by your
Gary Fisher dealer.
