Fitting feed screws. Ensure correct torques are used.
1. Place the feed screws on a flat surface and mesh them so that the ends are flush. Ensure that the screws are the correct way
around and the identification marks correspond with the markings on the shafts.
2. Fit both feed screws onto the shafts simultaneously and push them till they make contact with the mechanical seal sleeve. (To
make the splines fit you may need to rotate the shafts until they match).
3. Apply a locking compound to the feed screw nut thread.
4. Fit elastomer onto feed screw nut and lubricate it.
5. Insert a plastic/wooden block between the feed screw run outs to stop them from turning.
6. Tighten fluid screw nuts.
