Spindle Repair Tips
As a reference point, the grease fitting is in the top portion of spindle housing.
To minimize wear, bearing cups, cones and sleeves are press fit to shaft and will require a press or similar device for removal.
When disassembling, support housing casting to prevent damage.
Remove bearing cups by placing a punch in housing slots and driving cup out. Alternate punch positions from side to side. Use care to prevent housing damage.

Drive Spindle Disassembly (figure 17)
Remove dust cap (13). cotter pin (3) and nut (12). Press shaft (2) down through housing.
Remove seal (4).
Remove bearing cups (7)and (9) refer to Tips section above.
Drive Spindle Assembly (figure 17)
Bearing cups and cones are designed to work together. It is important to position them so bearing cone taper mates with bearing cup taper.
Lubricate new cups (7& 9) with a light oil. Place them in spindle housing (6) so they will mate with cones (5 & 10). Seat cups (7& 9) against machined shoulder of housing with a press or by placing a large soft drift on the flat lip and driving them into housing.
Place bottom bearing cone (5) onto spindle shaft (2) with taper up. Seat on bottom shoulder of shaft with a press.
Insert shaft and bearing cone assembly through bottom of housing (6). Fill housing cavity with a medium grade grease.
