4.1 - COMPATIBILITY WITH THE BOTTOM BRACKET SHELLS

3.1 - PEDAL PIVOT COMPATIBILITY

The Campagnolo Comp Ultra and Comp One cranksets are compatible with the following bottom bracket shells:

WARNING!

The pedal axle contact face must comply with the measure-ments indicated in Fig.2.These conditions are necessary to minimise the possibility of abnormal tensions in the hand cranks. Such tensions could lead to premature breaks and be the cause of accidents, physical injuries or even death.

NOTEQ-factor: 145.5 mm (nominal value).

WARNING!

Do not put washers between the pedal axle and hand crank as they would give rise to abnormal tensions in the interface area. Such tensions could lead to premature breaks and be the cause of accidents, physical injuries or even death.

When a frame is being produced the bottom bracket shell is often deformed and paint residues often remain on the edge and, where pre-sent, on the shell thread. Therefore, in order to prevent the bottom bracket cups from deviating from their ideal operating axis, the edges must be smoothed and where necessary rethreading done (unless the frame manufacturer has already seen to it).

5.1 - PREPARING THE FRAME

5 - ASSEMBLY

• Flatten the shell stops (Fig. 4) with the tool.

• Ensure that there is a water drainage hole on the bottom of the bot-tom bracket shell. If there is none, do not make one, but contact the frame manufacturer to clarify the issue.

• Mount the bottom bracket cups and the pin cover cylinder where possible (in case of EPS units) referring to the BOTTOM BRACKET CUPS OVER TORQUE section of the technical manual.

• Grease the retaining seals on the BB 386 EVO and PF BB30, in order to reduce friction between the seals and the crankset axle at minimum.

5.2 - INSTALLING THE CRANKSET

• For PF BB 30 or BB 30 bottom bracket shells insert the spacer on the axle.

• Fit the gasket (Fig. 5) on the crankset axle.

CAUTIONRespect the mounting direction of the gasket (the concave side must be facing the bottom bracket shell) as indicated in Fig. 6.

• Insert the crankset all the way into the bottom bracket shell (Fig. 7) so that the left bottom bracket cup pin protrudes and remove the plastic pin thread protection.

• Fit the second gasket, supplied, (the concave side must face the bottom bracket shell) on the protruding part of the axle (Fig. 8).

• Insert the play recovery system, taking care to respect the assembly direction (Fig. 9) (the edge with the “teeth” must therefore be facing outwards).

• For PF BB 30 or BB 30 bottom bracket shells insert the spacer on the axle (Fig. 10).

• Grease the cogged profile of the axle and the cogged profile of the hand crank, preferably using the synthetic specific lubricant for bearings.

• Insert the left hand crank on the axle (Fig. 12).

WARNING!

Make sure that the Campagnolo tool UT-FC220 has its drum positioned as shown in Fig. 13.If used as shown in Fig. 13.1 the hand crank axle could be damaged irreparably.

• Apply the Campagnolo tool UT-FC220 to the left hand crank and tighten the tool body (Fig. 14) until it stops, tightening it at least 2 complete turns.

CAUTIONTo make the next adjustment operations easier, insert the play recovery system so that the dowel (Fig. 11) is opposite where the left hand crank will go.

• If you are using the tool for OEM (P/N UT-FC120), tighten it by turning the external drum (Fig. 15).

• Now tighten the nut so that the hand crank engages in the axle and make sure that the hand crank is in the position indicated in fig. 16.

• A tightening torque of 40 Nm (354 in.lbs) is roughly enough to position the hand crank properly (Fig. 18).

• Remove the Campagnolo tool UT-FC120 from the left hand crank, unscrewing the nut in the opposite direction.

• If you are using tool UT-FC120, use an electric screwdriver for tightening and loosening (Fig. 19). Set the electric screwdriver at a torque of max. 50 Nm (443 in.lbs).

• Using a flat screwdriver, ensure that there is no “step” between the axle and the hand crank (Fig. 17).

• Align the four axles on the Campagnolo tool UT-FC130 with the holes on the closing ring (Fig. 21).

• Apply the torque wrench with 8 mm adapter to the Campagnolo tool UT-FC130 (Fig. 22).

• Tighten the ring nut to 8-10 Nm (71 - 89 in.lbs) (fig. 22) or if you are using an electric screw driver set torque at 8 - 10 Nm (71 - 89 in.lbs).

5.3 - ADJUSTMENT

• Insert a 1.5 mm Allen wrench in the play recovery system dowel and, with the aid of the wrench, turn the external ring nut counter-clockwise until it locks (Fig. 23 / Fig. 24).

• Position the closing ring nut as indicated in Fig. 20.

6 - DISASSEMBLY• Apply the 8 mm Allen wrench to the Campagnolo tool UT-FC130 (Fig. 26).

• Align the four pivots on the Campagnolo tool UT-FC130 with the holes on the closing ring (Fig. 27).

• Undo the closing ring nut and take it out as indicated in Fig. 28.

• Spray some antioxidant liquid on the axle.

• Partially unscrew the drum (Fig. 29) of the Campagnolo tool UT-FC130 so that it does not protrude from the side inwards (Fig. 29).

IMPORTANT!

If the drum is not loosened enough you could risk scratching the hand crank.

• Make sure there is no axial play between the hand crank and axle gasket: pushing the gasket from left to right (and vice versa) there should be no shifting in the position of the gasket.Tighten the dowel (Fig. 25) to lock the play recovery ring nut in po-sition.

• Remove the crankset from the bottom bracket shell (fig. 32).

WARNING!

If the chainring must be replaced, contact a Campagnolo® Ser-vice Centre so that the flatness can be carefully adjusted using specific instrumentation. The final assembly must be carried out carefully in order to prevent accidents, physical injury or death.

• Maintenance frequencies are purely indicative and can vary considerably depending on the intensity and conditions of use (for example: races, rain, salty roads in the winter, weight of the athlete etc.). Programme the most appropriate maintenance schedule with your mechanic.

• Periodically check that the hand crank closing ring nut and the chainring screws are tightened to the right torque values:

- hand crank closing ring nut: 8-10 Nm (71 - 89 in.lbs)- chainring securing screws: 8 Nm (71 in.lbs)

• Clean the crankset and the bottom bracket cups with specific bike products. NEVER use abrasive solvents or detergents.

• Do not expose the products to high temperature, do not leave them closed in cars parked under the sun, do not keep them near radia-tors or other heat sources, do not leave carbon or plastic products in direct sunlight.

NoteNever wash your bicycle with pressurised water.Pressurised water - even from a normal garden hose - may infiltrate the seals and into your Campagnolo® components, causing irreparable damage. Wash your bike and the Campagnolo® components carefully with soap and water.

7 - MAINTENANCE

• Position the Campagnolo tool UT-FC130 on the left hand crank as indicated in Fig. 30.Apply the 8 mm Allen wrench to the Campagnolo tool UT-FC130 and tighten the outside drum (Fig. 30) until the left hand crank comes out.

• Loosen the drum slightly and extract the hand crank from the Cam-pagnolo tool UT-FC130 (Fig. 31).

• Remove the play recovery system, easing it out of the axle. If you need to use it again, clean and lubricate the thread of the ring nuts to facilitate rotation.

• For PF BB 30 or BB 30 bottom bracket shells remove the spacer from the axle.
