1. Spindle Dis-Assembly, (See Figure 87) The Spindle Shaft is held in with 2 notched round Nuts
and a Tabbed Locking Washer, first use small Blunt Chisel to bend tab out away from Notch
on Round Nut, Using Tabbed Socket ( consult your local Tool supplier) un-screw outer Locking
Nut, Lift tabbed Washer off Shaft, un-screw lower Bearing Adjusting Nut. It is best to replace
Tabbed Washer with new one.
2. Remove Spindle Shaft, Because of fit of Upper Bearing Cone it will be required to Press Shaft
out through bottom of Housing, This should not take a great deal of effort but some. Put a soft
Metal Pin (Brass) into top hole of Shaft, (Do Not put one in that will be too big and get stuck). Using
Press; push Pin and Shaft Down, It will come out through bottom of Housing.
3. Remove Bearing Cones, Upper Bearing Cone will have stayed in Housing, reach in from to top
to remove it, Lower Bearing Cone should have come out and still be on Spindle, For Cleaning
and inspecting this Bearing Cone should be removed. You may need a Bearing Puller to remove
Lower Bearing Cone from Shaft.
4. Remove Lower Seal from Housing, Discard Old Seal Do Not re-use it only install new Seals.
5. Remove Bearing Cups, Bearing Cups will need to be driven out of Housing with a driver or
Pressed out, But they do Need to come out straight, DO NOT DRIVE them out from one side
only, keep equal force all the way around them when taking them out or Housing could be
damaged.
6. Cleaning Housing, Clean the Housing completely, No Oil or Grease left in it, Completely inspect
all areas of Housing, Bearing Cup Bore, Seal Bore, Flanges, Inner and Out surface of Housing
for scratches, cracks, Burrs (especially Seal Area for Burrs), Always Dry Parts after Cleaning,
Make sure there is no Solvent residue on them that will pollute lubricant, After Cleaning if Parts
are not to be assembled right a way put a coat of Oil over ID of Housing and over Gasket area
at the top to prevent rust, Un-painted Clean steel will rust very rapidly if left dry of Oil. Keep it
covered to keep dust and dirt from collecting on oiled surface.
