Airlock Seal Replacement Instructions
Regular maintenance on your Accu1Direct Model 9700 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 as 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 plates.
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.
