• Arrange the tube (1) on a firm support. Fill the
tube with rags to protect the spindle from
damage when pressing out.
• Fit the bottom plate (4B) on the tube (1).
• Fit the sleeve (4C) with inside diameter 0 90
mm on the bottom plate (4B).
• Place the spindle (S) upside down in the
bottom plate (4B). Check that the inner race
of the ball bearing is in contact with the face
of the sleeve (4C).
• Mount the three rods (4D) by fitting them
through the holes in the top bearing support
(T) and screwing them into the bottom plate
(4B).
• Fit the support ring (4E) on the spindle (S).
Notel
The inside diameter of this ring is
tapered.
• Fit the end tube (2) over the spindle (S) and
let it rest on the support ring (4E).
• Check that the retaining rings (4G) have been
fitted. Then fit the washer (4H) for the
compressing tool (3) onto the rods (4D).
• Fit the compressing tool (3).
Note!
The piston
must be in the top position.
• Fit the top plate (41) and secure the assembly
with the three nuts (4J).
• Arrange the handle of the compressing tool
(3) in Pos. 2 and then pump until the piston
has reached the bottom position.
• Bring the handle into Pos. 1 and pump until
the piston reaches its upper position.
• Place the spacer (4F) between piston and
end tube (2).
• Set the handle to Pos. 2 again and continue
to pump until the spindle is fully apart from
the ball bearings.
NOTE
Pump slowly during the final stage of
pressing out to avoid damage to the spindle
when this is released.
