Count Controlled Tester
Checking horizontal sliding pin guage 'F' and clearance between CAM and CAM follower.
- With Rocker Arm 'H' resting on Sliding Pin Gauge 'F' use a machinist's indicator and surface gauge 'Z' to determine if top of Rocker Arm is parallel to machine's base plate. If not, then correct by moving Sliding Pin's mounting up or down as required.
- Use Surface Gauge 'Z'.
- Adjust Indicator to get a reading of "5" (Bezel on indicator can be revolved).
- Stop motor when Cam is almost to lowest point.
- Hold Rocker Arm up and place 1/8" Shim Plate 'Y' between Cam & Cam Follower Bearing.
- Lower Rocker Arm so that Cam Follower rests on shim 'Y' on Cam, then pull the Sliding Gauge Pin out from under Rocker Arm.
- Jog motor to get very near to lowest point of Cam.
- Make very short jogs of motor and record smallest indicator reading as the lowest point of Cam passes Indicator. This lowest reading of Indicator should read same as item Number 3 above.
- If this smallest reading of Indicator doesn't read same as item Number 3 above then move Cam Mount up or down to get the same reading.
- The above helps assure the accuracy of Machine.
NOTE: It is still necessary to set up specimen accurately.
NOTE: Remove Shim 'Y' before operating machine.
