AIR SHIFT INFORMATION

(only on CS-1 style or center shift transmissions)

Air shifted LENCOS come pre adjusted from the factory. If it is necessary to remove the servos you should reinstall with the lock nut spun completely to the top of its travel. Screw the servo into the transmission case until contact is made with the shift fork pin. Now rotate counter clockwise 1/2 to 1 turn and tighten lock nut. No further adjustments are necessary as there is ample reserve travel in the servo.

(only on New Generation & Lencodrive or offset shift transmissions)

There are two different size air servos for the New Generation transmissions.The small air servo (2.5"piston diameter) and the large air servo(3"piston diameter) for the CS-2 large case transmission and Lencodrives. The air servo is attached to a rotary shift plate by an adjustable arm which is pre-set by the factory and should NOT be changed. The arm is held into the servo piston by a set screw. Run the air servo jam nut and o-ring up the threads on the servo. Screw air servo into case until it bottoms out against the jam nut. Rotate air servo into case until you see the set screw in the air servo piston boss inside the case. Apply a small amount of Red (271) Locktite on the set screw. After inserting arm into the air servo piston boss, run set screw in until you can no longer remove the arm from the piston boss. Warning: Do Not over tighten set screw. The arm must be free to move in all directions. Screw air servo counter-clockwise about five or six turns before you reassemble the transmission. Assemble next section on to case and bolt tight.

Adjustment

Once installed, make sure the air servo is loose and can turn freely. Remove fill plug on top the transmission case you are going to adjust. Sight through plug hole, where you will see the outer edge of the rotary shift plate. Screw air servo in (clockwise) until you see the rotary plate start to shift, now screw air servo Out (counter-clockwise) until the rotary shift plate stops moving. Then, continue to screw air servo Out (counter-clockwise) one half turn. This will allow for free play in the shift system. Run air servo jam nut and o-ring down against the case and tighten with a 1 1/2" wrench. Do Not Over Tighten. Add fluids as necessary and install fill plug. Attach air lines and your race ready.
