Step 2.
With the source on its side, re move the 10-32 flat-head screw from the cen ter of the spi der
plate. Note: Use a thin 7/8” open-end wrench ap plied to the ma chined hex on the bel lows to
pre vent twist ing the bel lows.
Step 3.
Pull the spi der plate and push rods out through their clear ance holes in the coil hous ing and
base plate. Any push rod, switch, or switch bracket can be changed or re placed by re mov ing
their re spec tive screws, fas ten ing them to the base plate.
Step 4.
Re move the eight buttonhead screws, fas ten ing the clamp ring to the top of the pneu matic
cyl in der and lift off the clamp ring, en sur ing that the cen ter hole clears the bel lows.
Step 5.
Re move the six socket head screws, fas ten ing the pneu matic cyl in der to the base plate to aid
cyl in der re moval from the base plate. Re move the seal ing disk. This thin disk is meant to
block any gas path through the pivot plate shaft’s, mount ing screws. Note ori en ta tion of
seal ing disk.
Step 6.
To re move the pis ton and bel lows from the cyl in der, use a 7/8” wrench on the ma chined hex
of the bel lows and a 5/32” Al len key wrench on the bot tom of the pis ton and loosen.
Step 7.
In spect and re place any worn o-rings. Note: In spect the ½” o-ring that forms the seal be -
tween the pis ton shaft and pneu matic cyl in der.
Step 8.
If this is a bot tom-drive source, turn it over and re move the three socket-head screws that se -
cure the drive as sem bly to the bot tom of the source and re move the drive as sem bly. For in -
struc tions on dis as sem bling the drive as sem bly, see sec tion 5.4.
Step 9.
Now you are ready to re move the screws that se cure the cru ci ble to the cru ci ble mount ing
flange. This pro ce dure in volves us ing the spe cial Allen tool pro vided with the source, which
con sists of a stan dard 7/64" Allen driver with a ma chined sleeve fit ted over the shaft (see
Fig ures 5-2 and 5-3). If you are not ex pe ri enced with this tool, see the de tailed in struc tions
