6. With the shaft removed, note the orientation of the
timing marks on the piston
sleeve and ring gear in
the housing as below.
The adjacent weld can make the ring gear timing
marks difficult to locate; using a light can help.
Again,
mark the teeth with a felt tip marker to make
the marks
easier to see and to simplify timing during
reassembly. Drive the piston sleeve out of the hous-
ing using the handle of a rubber mallet as shown
below.
Support the piston sleeve as it is removed from the
housing. Great care should be taken to insure that
the gear teeth are not damaged and the piston
sleeve does not damage the housing bore as it is
removed.
7. Remove all seals and bearings from their grooves.
Note the orientation of the sealing lips prior to
removal.
8. Clean all components thoroughly with solvent or in a
parts washer. Be sure to flush all grease and con-
taminants from the grease fittings and grease relief
passages.
