Spindle Repair Tips
As a reference point, the grease fitting is in the top
portion of spindle housing.
To minimize wear, bearing cups, 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.
Permatex 3D Aviation or equiva-
lent is recommended as a sealant for spindle repair.
Drive Spindle Disassembly (figure
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
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 assembly through
bottom of housing (6). Fill housing cavity with a
medium grade grease.
