Description:
Scubapro MK11/MK16/MK17/MK18/MK19Evo & TUSA R400 First Stage Tool
The First Stage Tool is designed to assist the technician in several assembly
and disassembly operations. These functions are:
Removing the seat:
The stepped end of the tool is inserted into the first stage body so that the
intermediate ledge on the tool shaft blocks the hole in the center of the HP
seat. A rubber tipped blow gun is positioned on the opposite side of the first
stage body, so that the tip is sealed against the center air flow port. While
holding the tool in place against the seat, tap the blow gun trigger gently. The
seat can be completely removed with a small o’ring pick.
Installing the HP seat :
The HP seat assembly can be easily installed in the first stage body by placing
the seat assembly onto the small end of the shaft and pushing it fully into the
internal ledge in the first stage body.
Removing/Installing the balancing chamber:
One end of the brass tool body has been machined to index with the recessed
balanced chamber flats. The balanced chamber can be easily removed and installed
with this tool feature. The balanced chamber utilizes standard right hand
threads.
Installing the balancing chamber washer and o-ring:
The recommended method for reassembling the Mark 16 pressure control components
is to insert the small washer and o-ring into the balanced chamber. This is done
using the small ledge on the tool shaft. The poppet assembly (poppet, poppet
guide, spring, and washer) is inserted into the first stage and centered before
the balanced chamber, washer, and o-ring are threaded into place. Installing the
larger washer with the poppet assembly helps to insure that the poppet stem will
be accurately guided into the balancing chamber and through the o-ring and
smaller washer.
