Instructions
CD-38200-1.370
1. On a VAR
PR-90100
(simple arm) professional repair stand or VAR
PR-90200
(double arm), place the frame you need to machine in order to benefit an excellent
stability.
2. Tighten both arms on the body (133mm length) and the pilot (228mm length).
3. Generously and regularly spray the taps and the bottom bracket shell with VAR
CD-77000
cutting fluid in order ton obtain good results and extend the taps lifespan.
4. Drive side, place the
CD-38211-1.370
tap-equipped pilot. On the opposite side,
place the
CD-38210-1.370
tap-equipped body .
Both taps having a gradual head, it is important, in order not to damage the bottom
bracket shell, to engage both taps at the same time, the pilot centering the tool.
5. Perform one to two rotations following the taps directions (to the left on the drive
side and to the right on the opposite side) so the tool holds itself inside the bottom
bracket shell.
6. Thread both sides simultaneously until perception of a resistance. From this
moment, perform only by quarters of a turn following the resistance and half a turn
backwards to break the created metal shavings.
7. Follow the taps progression until the rear side of the taps comes flush with the
bottom bracket shell.
8. Remove the taps simultaneously from the bottom bracket shell, in order not to
damage the newly created or refreshed threads.
9. Thoroughly clean the bottom bracket shell with a clean cloth, a brush and VAR
NL-75300
degreaser to remove any used cutting fluid and metal shavings.
10. Generously grease the bottom bracket shell threads with VAR
