a) Remove four of the six hex-head socket cap screws (53) securing the seal cover (51), leaving
two screws symmetrically positioned. Now loosen the remaining two screws alternately,
allowing the shaft seal spring (110) to push off the cover slightly. If the cover adheres to the
gasket, free it manually after the screws have been loosened.

b) Remove the seal cover. The carbon insert (101) is fitted inside the cover. Draw the cover out
over the end of the shaft being careful to prevent the carbon from hitting against the shaft.
Next, remove the O-ring (49) between the seal cover (51) and the seal retainer (48).
c) After the seal cover has been removed, wipe the shaft off and inspect it closely.
If any scratches are observed on the shaft surface, finish with fine emery paper in order to
prevent damaging the O-ring when it is pulled out of the seal.

d) Loosen the setscrews (111) securing the shaft seal collar (109). In the case of Model 160, the
plugs must first be removed from the bearing cover before a hex wrench can be inserted.
In the case of model 200 and above, start from the seal cover disassembly procedure.
Loosen the setscrews 3a4 turns (do not remove completely) until the end clears the shaft and
enters the seal collar.
e) Grasp the seal collar (109) with your fingertips and withdraw carefully, making sure that the
setscrew points do not catch on the shaft and scratch it.
f) Insert two eye bolts into the screw holes in the seal retainer (48) and draw it off parallel to the
shaft. Be careful not to slant the retainer when withdrawing.
g) Remove the sleeve of the oil seal (528) after loosening the two setscrews (529).
