4. Install ring over the sleeve. Make sure ring is able
to rotate free of the springs.
5. Insert cross pin into the spool and sleeve (Fig. 69).
6. Install bearing assembly onto the spool and sleeve
(Fig. 72).
7. Coat new O--ring/kin--ring lightly with petroleum jel-
ly. Install ring carefully into the inner bore of the housing
so that they fit snuggly in place (Fig. 73 and 74).
Note: The cross pin should be held horizontal when
inserting the spool and sleeve into the housing.
Note: The clearance between the sleeve and the
housing bore is very tight. The heat from one’s hand can
cause the sleeve to expand enough so that it will not fit
into the housing. Refrigerate the spool/sleeve assembly
prior to installation. Insulate assembly from one’s hand
when installing.
8. Guide spool and sleeve into the housing carefully by
using a light turning motion. Be careful not to damage
the O--ring/kin--ring.
9. Place ball into the largest threaded hole. Secure ball
into hole by threading in the bushing. Make sure the top
of the bushing lies just bellow the surface of the housing
(Fig. 74).
10. Coat new O--ring lightly with petroleum jelly. Install
O--ring into groove on housing surface.
11. Mount distributor plate onto housing. Make sure
channel holes in plate match the hole of the housing.
12. Insert cardan shaft carefully into the bore of the
housing. Make sure shaft slot is parallel with the surface
of the connection flange.
13. Coat both new O--rings lightly with petroleum jelly.
Install O--rings into grooves on rim of gear wheel set.
Place rim onto distributor plate.
IMPORTANT: The gear wheel fits into the cardan
shaft from one direction only. The tooth base on the
wheel should be positioned in relation to the shaft
slot (Fig. 75).
14. Fit gear wheel onto cardan shaft and into the rim.
Make sure holes in rim are aligned with holes in the
housing.
15. Install end cover onto rim of gear wheel.
