MAINTENANCE

Blade Spindle Assembly

1.

Bearing cups and cones are designed to work

together. It is important to position them so

bearing cone taper mates with bearing cup

taper.

2. Lubricate new cups with a light oil. Place them

in spindle housing so they will mate with cones.
Seat cups against machined shoulder of hous-
ing with a press or by placing a large drift on the
flat lip and driving them into housing.

3.

Place bottom bearing cone onto spindle shaft

with taper up. Seat on bottom shoulder of shaft
with a press.

4.

Insert shaft and bearing cone assembly through
bottom of

housing cavity with a

lithium grease of

consistency with a

MOLY

(molybdenum disulfide) additive.

5.

Place top bearing cone on shaft to mate with

top bearing cup.

Bearing adjustment

is

set by

pressing sleeve against bearing cone until
proper adjustment

is

attained.

6.

Install sleeve on shaft and press sleeve and
bearing cone onto shaft until all bearing free
play is removed and there is a slight drag
(similar to adjusting the front wheel bearings on
an automobile). Check by spinning spindle. It
should turn freely.

6.

Be careful not to over-tighten bearings. Proper
bearing adjustment

is

essential to good bearing

life.

7.

Should you over-tighten bearings, hold spindle
housing and rap spindle shaft with a lead
hammer to loosen bearings. Readjust bearings
until proper setting is obtained.

Improper positioning

of

seals

can cause seal failure.

8.

Proper seal installation is important.

erly installed seal will leak and could cause

bearing failure.
