2. If removed, replace the exhaust tee cover(5) onto the exhaust
tee portion of the housing(4) by holding the cover at a slight
angle to the housing with the bottom raised and mating the top
of it with the hinge tabs on the housing. Ensure that the top is
aligned, then press the cover in toward the housing until it snaps
into place. Thread the two cap screws(7) into the housing and
tighten each 1/4 turn at a time using a 3/32" hex key to a torque
of 4 in/lbs. DO NOT over tighten.
3. Replace the poppet seat(14) into the poppet(15), with the side
that is perfectly smooth facing out. Ensure that it is completely
seated, flush with the rim of the poppet. DO NOT use adhesive.
4. Apply a light film of lubricant to each end of the spring(16) and
place onto the poppet(15). Fit the poppet into the pronged end of
the poppet installation tool and insert the poppet shaft completely
through the inlet tube of the housing(4) compressing the spring
until the threaded portion of the shaft is completely visible inside
the housing. Hold in position by grasping the tool with the fingers
and the outer rim of the housing with the thumb (Fig. 10).
5. Place the washer(18) over the threads of the poppet(15) and
onto the shaft. Place the spacer(19) onto the poppet shaft. Turn
the locking nut(20) clockwise onto the poppet threads with your
finger tips until threading is started. (Fig. 10) Then, while still
compressing the spring(16) with the poppet installation tool, insert
a 1/4" nut driver through the open adjustment port of the hous-
ing(4) and turn the locking nut(20) further onto the poppet until
3 threads are showing beyond the outer surface of the locking
nut. (Fig.10 insert). Remove the tools.
CAUTION: It is very important that a minimum of 2-3 threads
of the poppet shaft are adjusted outside the locking nut. The
lever arm may otherwise become caught on the end of the
poppet shaft, resulting in an uncontrolled free flow.
6. Lubricate and install the balance shaft o-ring(23) into the small
opening end of the adjustment tube(24). Install the snap wash-
er(22), smooth end down, into the adjustment tube(24) directly
over the balance shaft o-ring(23), causing the washer to "snap"
securely into position. (Fig. 11) Insert the balance shaft(21) into
the small opening end of the adjustment tube(24) through the
snap washer(22) and balance shaft o-ring(23). (Fig. 12).
7. Lubricate and install the o-ring(25) onto the adjustment tube(24).
Holding the smaller end of the adjustment tube, insert it, threaded
end first, down into the housing and angle it into the adjustment
tube opening in the side of the housing. Ensure that the adjust-
ment tube flange mates flat against the inner wall of the opening.
If necessary, grasp the outer threads and rotate the tube until the
surfaces mate.
8. If previously removed, install the piston spring follower(28) on
the adjustment stem(29). Screw it on counterclockwise, flat side
first. DO NOT tighten with a wrench.
