VIBRATOR HEADS — MAINTENANCE
4.Remove the cap screw or hex nut that holds the lower bearings in place. (Ref. 2)
5.Remove the spindle with the upper bearings still attached. The lower bearings
6.Remove and discard the oil seals. Note the way the seals face so that the new seals will be installed correctly. (Ref. 5)
7.Thoroughly clean all parts with a degreasing solvent and blow dry with air. Compressed air is not recommended for cleaning and drying solvents out of the bearings. Bearings should never be spun at high speed using compressed air. (Ref. 3)
8.After cleaning, inspect all parts for wear. The bearings should be checked by applying a light thrust load against one bearing ring, while slowly rotating the other ring. Do this in both directions. If any roughness or excessive looseness is felt, the bearing should be replaced. Any other parts that show heavy wear should also be replaced at this time. (Ref. 3)
6.Apply a high strength anaerobic sealant to the external threads of the casing adapter. Screw the adapter into the housing and tighten. Threads are
7.Tip head over and pour in the required amount of Stow Lube P/N
CAUTION!
DO NOT use more than the specified amount of lubricant in the vibrator head.
8.Assemble the lower bearings to the spindle. (Ref. 3)
9.Clean the tip threads and the mating threads on the housing with anaerobic sealant primer. Allow to dry. (Ref. 1,12)
10.Apply a high strength anaerobic sealant to the tip threads and screw the tip into the housing. Threads are
To Reassemble a Vibrator Head:
1.Bearing Installation: Bearing installation should take place under the cleanest possible conditions. Inspect the spindle bearing seat diameter for nicks and burrs. If any are found, carefully remove using a stone or fine file. Wipe the bearing seat diameter with head oil to help prevent galling while the bearing is being pressed on. While installing the bearing, the installation force should always be applied squarely and evenly to the inner race of the bearing. (Ref. 3)
2.Seal Installation: Remove any nicks or burrs that will interfere with the installation of the seal. Make sure the seal is facing the right direction and that it is properly positioned so that it will seat squarely without damage. See illustration on page 12. Use an installation tool that will apply the force evenly around the outer edge of the seal.
3.Insert the spindle with upper bearings assembled on it, into the housing. Using a light push fit, seat the bearings into the housing. (Ref. 4)
4.Insert the seals into the casing adapter per the seal installation instructions. (See page 12)
5.Clean the casing adapter external threads and the mating internal threads on the housing with anaerobic primer and let dry. (Ref. 1,9)
Assemble the Head to the Casing:
11.Clean the casing threads and the mating threads on the head with an anaerobic sealant primer and allow to dry.
12.Apply a ring of anaerobic high strength sealand to the casing threads. Screw the casing into the head and tighten.
13.Allow to set one hour before use.
