d.
Remove old wear sleeves by using a 3/4 inch (19 mm) chisel and a hammer. Grind a 1/16 inch (1.59
mm) radius on the cutting edge of the chisel. Using moderate blows with the hammer, strike the chisel
against the wear sleeve at three to six equidistant points on the outside diameter of the wear sleeve.
This will relieve the press-fit of the sleeve allowing it to be removed by hand.
e.
After the old wear sleeve is removed, the surface should be cleaned and polished with crocus cloth.
More advanced corrosion deposits may require the use of emery cloth.
f.
Should a repair sleeve be required, select the p oper repair sleeve and install using the installation tool
r
provided with the sleeve.
g.
Clean the old seal surface thoroughly. File down any burrs and clean up any rough spots.
h.
Note the position of the repair sleeve required to cover the prior seal wear pattern. Ensure the
disposable tool (2, FIG. 4-62) supplied with each repair sleeve will position the sleeve correctly. If
a longer installation tool is required, see step (n).
i.
Place the repair sleeve (1) over the worn or damaged area. If more clearance is required, the repair
sleeve flange can be removed by sawing through the flange to the pre-cut groove (3).
j.
If the crankshaft seal area is deeply scored, fill the groove with powdered metal epoxy type filler and
install the repair sleeve before the filler hardens.
k.
If the groove in the crankshaft does not require filling, apply a light coating of non-hardening sealant to
the inner surface of the repair sleeve.
l.
Place the repair sleeve into the end of the installationtool. Gently tap the center of the installation tool
until the sleeve reaches a point on the crankshaft covering the wear pattern from the prior seal.
NOTE
Use a wood block or large-faced mallet to avoid caving in the back of the
installation tool. Remove any excess filler or sealer.
m.
Remove the repair sleeve flange by starting at the saw line (step i). Use side cut pliers to pull the
flange away from the seal surface and twist into a coil. The flange will break loose along the pre-cut
line.
