7. Stop the main drive motor and place the Stroking

Selector Switch in the OFF position. Make certain
that the flywheel has stopped turning completely.
Attach a WARNING sign to the press controls to
warn other personnel that the press is currently
being serviced.

8. Exhaust all air pressure from the counterbalance

cylinder.

9. Place a hydraulic jack between the slide face and

the bed (or bolster). Place the jack directly under
the slide connection screw.

NOTE: To prevent damage to the slide and/or bed,

place flat steel plates between the jack and
the slide and between the jack and the bed.

10. Place a dial indicator on the press frame and indi-

cate to the crankshaft. Make certain the indicator
is placed on the flywheel (or main gear) side of the
press. (See Figure 1G.) Set the indicator dial to “0”
reading.

11. Energize the hydraulic jack and apply enough pres-

sure to support the slide assembly and crankshaft.

NOTE: Applied jack pressure should never

exceed 5 percent of press rated tonnage.

12. The reading on the indicator dial now is the main

bearing clearance on the flywheel (or main gear)
side of the press. Record this reading.

13. Apply and release jack pressure several times

until consistent readings are obtained.
