CAMS
DESCRIPTION:
The two Cam Handles lock the Neck Ring tight against
the Neoprene Gasket with four points, for an effective
water tight seal. The Cams are simple, rugged and de-
signed for quick, jam-proof operation. They are easily
adjusted with the Handle Screw and Cam Nuts.
MAINTENANCE AND REPLACEMENT
1. To remove handle, loosen Cam Lock Nut and unscrew
the Handle Screw at the rear Helmet ear and remove the
Cam.
2. To replace Cam Handle, install Cam on rear Helmet
ear in this order:
3. Place Screw through ear, from top down.
4. Position Washers, usually three, under rear ear.
5. Install Cam Nut under Washers (not tight).
6. Place Cam on bottom and fasten with Screw until snug.
7. Tighten Cam Nut against Cam. The Screw, Cam Nut,
and Cam are now locked together. The Cam Handle should
swivel freely, without up and down play, on the rear Hel-
met ear.
8. The front ear tension adjusts with Screw and Lock Nut.
NOTE: The amount of washers determines the amount of
tension on rear ear, to lock the Neck Ring in place. Three
Washers are normally used in both front and rear ear.
Proper tension is achieved when pressure is sufficient to
press Neck Ring into the Gasket and Dam approximately
1/16 of an inch.
12. Place Split Clip Ring on Handle between threads and
top.
13. Screw the Handle into the Exhaust Body, allowing 1/4
in. space between the Body and Handle top. Clip Ring
may now be forced into the retaining groove in Exhaust
Body using a blunt screwdriver. (The purpose of clip ring
is to prevent the handle from unscrewing all the way out
of the Exhaust Body).
