Driving out needle sleeve
with press arbor 1120 893 7200
Use the press arbor to drive the
needle sleeves out of the crankcase,
from the outside to the inside in each
case.
If the crankcase is damaged in any
way it must be replaced as a com-
plete unit (both halves). Always
install new needle sleeves and oil
seals in such a case. All other parts
which are still serviceable can then
be transferred from the old to the
new crankcase.

- Assembly of Crankcase
Top:
Cleaning sealing faces
Center:
Needle sleeve correctly positioned
Bottom:
Pressing in needle sleeve
If the old crankcase is used again,
carefully clean the sealing faces. Use
a scraper or similar suitable tool to
clean off gasket residue before fitting
the new gasket.
The crankshaft bearings (needle
sleeves) should be pressed into the
crankcase halves from the inside to
the outside. Do not heat the crank-
case for this purpose.
The needle sleeves will only be cor-
rectly seated in the crankcase if the
press arbor is used.
Important: The needle sleeves must
be positioned on the press arbor so
that the arbor's large diameter butts
against the reinforced rim of the
needle sleeve.
The needle sleeves are then placed
in the crankcase and pressed home
until the arbor butts against the crank-
case.
Then use press sleeve to press in the
oil seals from the outside to the inside.
