GENERAL ASSEMBLY INSTRUCTIONS
•
Assembly should be performed in a clean environment.
•
All parts should be cleaned thoroughly and wiped dry before assembly.
•
Oil all parts by hand using Rock Drill Oil to insure easy assembly.
•
Coat all thread connections and thrust washers with a thread compound to allow joints
to thread easily.
FEED TUBE ASSEMBLY
•
Install the two feed tube o-rings in the two grooves located in the smallest inside
diameter of the feed tube housing.
•
Insert the three orifice o-rings into the groove at the inside diameter of the feed tube.
•
Place the feed tube compression ring over bottom end of the feed tube, then slide it
along the feed tube until it seats against the feed tube collar.
•
Position the piston vertically. Place the smallest outside diameter of the feed tube
housing on the piston so that the bores will align. Insert the small end of the feed tube
into the feed tube housing. Slide the feed tube into the feed tube housing until the feed
tube compression ring seats against the feed tube housing shoulder. While applying
pressure to the feed tube collar to expose the snap ring groove, use a large screwdriver
to insert the feed tube snap ring. Remove the feed tube assembly from the piston.
