2.Install outer bearing spacer into top of spindle hous- ing. The spacer should fit against the snap ring.
3.Using an arbor press, push the bearing cups into the top and bottom of the spindle housing. The top bearing cup must contact the outer bearing spacer previously installed, and the bottom bearing cup must contact the snap ring. Make sure that the assembly is correct by supporting the first bearing cup and pressing the second cup against it (Fig 18).
4.Pack the bearing cones with grease. Apply a film of grease on lips of oil seals and
5.Install lower bearing cone and oil seal into bottom of spindle housing. Note: The bottom seal must have the lip facing out (down) (Fig. 19). This seal installation al- lows grease to purge from the spindle during the lubrica- tion process.
IMPORTANT: If bearings are being replaced, make sure to use the spacer ring that is included with new bearing set (Fig. 17).
6.Slide spacer ring and inner bearing spacer into spindle housing, then install upper bearing cone and oil seal into top of housing. Note: The upper seal must have the lip facing in (down) (Fig. 19). Also, upper seal should be flush or up to 0.060” (1.5 mm) recessed into housing.
7.Inspect the spindle shaft and shaft spacer to make sure there are no burrs or nicks that could possibly dam- age the oil seals. Lubricate the shaft and spacer with grease.
8.Install spindle shaft spacer onto shaft. Place thin sleeve or tape on spindle shaft splines to prevent seal damage during shaft installation.
9.Carefully slide spindle shaft with spacer up through spindle housing. The bottom oil seal and spindle spacer fit together when the spindle is fully installed.
10.Install
11.Install pulley (hub down), hardened washer and lock nut to spindle shaft. Tighten lock nut from 130 to 150
IMPORTANT: Pneumatic grease guns can produce air pockets when filling large cavities and therefore, are not recommended to be used for proper greas- ing of spindle housings.
12.Attach a hand pump grease gun to grease fitting on housing and fill housing cavity with grease until grease starts to come out of lower seal.
13.Rotate spindle shaft to make sure that it turns freely.
