Series F11
Bulletin HY30-5503-M1/UK
Series F11-28 and -58 cylinder barrel can be removed
from the barrel post after removal of the leaf spring
locating pin (utilizing a screwdriver as shown), the leaf
spring, and the hold-down bearing ring.
5. Remove the retaining ring, the back-up washer, and
the shaft seal.
4. Using a bearing press, push the shaft assembly out
of the bearing housing on a suitable support. The shaft
assembly can also be removed by grasping the housing
and carefully hitting the shaft against a wooden block as
shown.
7. To remove the cylinder barrel from the housing (does
not apply to Series F11-28 and -58), carefully hit the
housing/barrel assembly against a piece of wood as
shown; the barrel as well as the valve plate will be forced
out. Be careful to protect the barrel and valve plate from
damage.
6. Do not disassemble the shaft assembly unless the
bearings are worn or damaged. If the bearings or the
shaft have to be replaced, remove the locknut and the
tab washer, and position the shaft assembly on a piece
of pipe or other suitable support that fits snugly around
the shaft and supports the ring gear. The shaft can now
be pressed out.
