Install Valve Rod
1. Insert the Valve rod (58693-1) into the gun block. Use the seal installation tool to
center the valve rod.
Note: Make sure that the valve rod is correctly aligned. The slotted end of the valve
rod should be on the left side of the gun block with the hole for the actuating stem
pointing down. The middle hole, into which the actuating stem will be inserted,
must also be correctly aligned. One end of the hole has a relief; and this relief
should face out of the gun block, as this is where the actuating stem will be
installed.
Reinstall Actuating Stem
1. Screw the Actuating stem (5104-11-1) into the Valve rod (58693-1) thru the
center spacer.
Note: Make sure the actuating stem is screwed into the side of the valve rod with
the larger hole (thread relief).
2. Look down the front of the gun while moving the actuating stem back and forth.
You should be able to see the holes open and close. The holes should be open
when the actuating stem is at the back of the gun block and closed when the
actuating stem is forward towards the front of the gun block.

2. Move the actuating stem back and forth, opening and closing the gun.
3. Again tighten both packing nuts.
