AIRLOCK SEAL REPLACEMENT
INSTRUCTIONS
Regular maintenance on your Accu1 blowing and spraying machine will extend the life of the equipment and
provide better production. Replace all of your airlock seals as soon as a decrease in production occurs. Airlock
seal life may vary dramatically because of such factors s type and quality of material used (the more abrasive
the material, the shorter the seal life) and damaging objects like knives, hammers, or nails.
TO REPLACE SEALS:
1.
Remove airlock drive chain.
2.
Remove sprocket on airlock.
3.
Loosen set screws on both airlock bearings.
4.
Remove bearings on front and back airlock plate.
5.
Remove front airlock plate (outlet tube plate).
6.
Remove rotor.
7.
Remove old seals.
8.
Clean rotor and check for damage.
9.
Slide felt and foam rings into place as shown below.
10.
Put new seals into place with the thinner ply side against the plate that is
welded to the rotor; tighten the bolts only slightly.
11.
Square up edges and press rubber firmly against felt and foam rings;
tighten bolts (bolts are too tight if rubber squeezes out between plates).
12.
Check airlock housing for any damage before re-assembly.
13.
Reassemble by reversing process.
14.
Be sure to promptly replace worn agitator paddles, because worn paddles
will also reduce machine production.
