HMartin®Hurricane Air Cannon Main Piston Rebuild Instructions
IMPORTANT
Read entire section before beginning work. All safety
rules defined in your air cannon’s documentation, and
all owner/employer safety rules, must be strictly
followed when installing and servicing this equipment.
DANGER
!
Turn off and lock out/tag out air supply and energy
source before blasting air cannon to prevent air
cannon from refilling.
Do not open door/port or enter structure before
turning off compressed air source, locking out
controls, purging line pressure, and venting air from
tank. Opening structure door while cannon is
operational can kill you.
1. Turn off and lock out/tag out energy source according to American National Standards Institute (ANSI)
z244.1-1982 and Federal Register, Volume 54, Number 169, Part IV, 29 CFR Part 1910.
2. Blast air cannon to remove air from tank. If tank has a relief valve, pull ring to make sure air stored in
cannon has been released.
3. Close safety slide gate if equipped with one. If air cannon has an open discharge port, make sure you
are safely isolated from free flowing material or hazards inside the discharge area.
4. Disconnect air lines.
5. Remove bolts from valve assembly.

6. Remove the valve from tank.
7. Remove 1/4-in. bolts that hold basket to exhaust valve.
8. Remove old piston and spring assembly.
9. Inspect bearing surface for excessive wear or stress fractures in the aluminum casting.
10. Remove o-rings and clean all mating surfaces.
IMPORTANT
All o-ring mating surfaces need to be clean and smooth
for an air tight seal. Apply a small amount of grease to
o-rings to ensure o-rings stay secure in the o-ring
groove during assembly. Make sure o-rings are not
pinched during reassembly.
11. Install new piston and spring into bearing basket.
12. Install o-ring on exhaust valve.

18. Install compression washers and bolts.
19. Connect air lines and check for leaks.
20. Move the safety slide gate to the open position and install pin.
21. Slowly pressurize the air cannon and check for leaks.
22. Pressurize the air cannon and test fire to make sure all connections are correct.
23. The Martin®Hurricane Air Cannon is now ready for operation. Watch air gauge when cannon is fired.
The needle should drop to “zero” instantly. The exhaust port elbows should be pointing down, so dirt
does not fall into the exhaust valve.

Martin®Hurricane Air Cannon Exhaust Valve Rebuild Instructions
1. Remove lever cap and pipe elbows.
2. Hold woodruff key, supplied in the kit, in the valve stem slot using locking pliers. Remove the flat head
screw from the valve stem. Usually a quick hit with a dead blow hammer will break the threadlocker
adhesive free.
3. Disassemble the rest of the exhaust valve, and check for wear on the piston pocket and valve stem seat.
4. Clean all areas of the exhaust valve.

5. Drive out bearing sleeve using a standard (7/16”) deep well socket.
6. Press in new bearing sleeve using the next size socket (1/2”) on the bearing and lightly tapping with
the dead blow hammer.
7. To reassemble the valve, threadlocker and primer will be needed for the screw and blind hole.

8. Insert woodruff key into key way in valve stem. Tap the key with a hammer to press it into key way.
9. Insert air inlet valve into valve body cap.
10. Insert compression spring and piston into valve body cap.
11. Apply primer to blind hole and screw, and let dry 3–5 minutes. Apply three drops of medium-duty
threadlocker in the blind hole and two drops on the screw. Hold the key using locking pliers while
tightening the screw. Tighten the screw to 12 ft-lbs.
IMPORTANT
Allow 24 hours for the threadlocker to cure.
12. Insert lip seal into valve body cap. Make sure orientation of lip seal is correct.

13. Insert the urethane bumper into the hub using a dead blow hammer.
14. Remove the woodruff key. It is only to be used for assembly purposes.
15. Install elbows pointing down during service, so material will not collect in the exhaust valve. The
elbow connections should be snug, but still adjustable. Install manual lever cap and tighten the cap
screws to12 ft-lbs.
