SERVICE INSTRUCTIONS
SI-1TG0H-001
Note
* Check that the fixing bolt of the bottom bracket cable
guide is not so long that it touches the inner cover. If the
fixing bolt touches the inner cover, it may damage the
inner cover, which will result in a drop in waterproofing
performance.
* Apply grease to the R.H. adapter and L.H. adapter before
installing them to the hanger.
* Apply grease to the surface which contacts the crank arm
before installing the crank arm.
* For maximum performance we highly recommend
Shimano lubricants and maintenance products.
Installation of the Bottom Bracket (BB-7700)
1. Insert the main unit into the
hanger. After checking that
the inner cover is securely
attached to the R.H. adapter,
place them onto the hanger.
2. Tighten the right-hand adapter
by turning it counterclockwise
using the special tool (TL-FC31).
(clockwise for 70 mm [M36]
bottom brackets)
Tightening torque:
50 - 70 Nm
{435 - 608 in. lbs.}

R.H. adapter
3. Use the special tool (TL-UN74-S)
to tighten the left-hand adapter
clockwise until the spindle
turning effort increases sharply.
After tightening the left-hand
adapter, loosen it by about 1/16
to 1/8 of a turn so that the
spindle rotates smoothly.
5. Apply grease to the seal guards and then attach the seal
guards to the spindle, while making sure that the grooves of
the seal rings face inward. If the grooves face outward
after the seal rings are installed, the water-tightness
will drop significantly. (The seal guards are
pushed into the proper
positions when the crank
arms are installed, so do
not force the seal rings on
when installing them.)
6. Install the right-hand crank arm, and then check that there is
no play in the bearing cone is adjusted correctly. If there is
some play in the bearing cone, loosen the lock ring and then
tighten the left-hand adapter by as little as possible. Repeat
steps 4 and 6 until there is no more play.
4. Use the special tool (TL-FC31) to tighten the lock ring while
using the special tool (TL-UN74-S) to push in the left-hand
adapter.

Maintenance
●Apply grease to each part at periodic intervals. (Refer to the illustration.)
●Water can get inside the bottom bracket. If using a frame which does
not have water drainage holes in the hanger, be sure to drain any water
which has collected inside the hanger before removing the bottom
bracket.
