Step 1: Inspect and Prepare Housing
To achieve proper bearing t, the housing should be ma-
chined to the correct bore size. For recommended housing
bore sizes, refer to the Browning bearing catalog or consult
Application Engineering. The housing bearing seat should be
wiped clean and free of debris.
Step 2: Install Unit in Housing
Press bearing into housing by applying force to the face of
the outer ring. Do not hammer on any component of the
bearing or apply force to the inner ring.
Step 3: Refer to Steps 1 - 5 from the
“Mounting Housed Bearing Units” Section
Pages G-255 to G-256
Replacing Existing Browning Inserts:
Note: Replacement Browning bearing inserts are intended
for use in Browning housings only.
Step 1: Loosen and Remove Housing
Mounting Bolts
Step 2: Remove Bearing from Shaft
Loosen the locking mechanism and slide the bearing off the
shaft.
Step 3: Remove the Bearing Insert from the
Housing
Secure housing in a vise. Using a bar placed in the insert bore
as a lever, swing the insert to line up the outer ring with the
load slots and remove insert from load slots.
Step 4: Inspect and Prepare Housing
Housings should be inspected for damage prior to installa-
tion. Wipe housing bore clean as necessary and check that
the lubrication groove and hole are clean and free of debris.
Wetting of the housing bore with oil or grease may be done
to ease installation of bearing insert.
Step 5: Load New Insert
With the bearing housing still in the vise, load the insert in
the following fashion:
a. Place the bearing insert into the housing load slots, posi-
tioning the anti rotation rivet on the outer ring in the load
slot as to not shear it off when the swinging insert into place.
Also, position the outer ring lubrication hole so it will install
in line with the housing lubrication hole.
b. Using a bar placed in the insert bore as a lever, swing the
insert into place within the housing. Insert should have a
snug t in the housing. If insert can be made to swivel by
hand in the housing bore, t is too lose and entire unit should
be replaced. If heavy force is required, t is too tight and
entire unit should be replaced.
c. Ensure alignment of the anti rotation rivet in the load slot
and outer ring lubrication hole in the housing lubrication
hole.
