cover will, if the casing has been placed in the position specified, itseh push the star against the cam by gravity, thus providing the required adjustment.
BE CAREFUL NOW and so hold the cover that it cannot move, while you retighten the holding screwTs. Do NOT tighten one screw tight and then the next one, etc. Set one screw down until it just snugs the cover to the casing, then set the opposite one the same, after which do the others the same. Then give each screw, in its turn, a slight turn, until you have them all pulled down tight.
END PLAY OF FLYWHEEL may be remedied as follows : Loosen, but do not remove the screw in the knurled knob on end of flywheel shaft. Insert point of screw-driver into slotted end of flywheel shaft and turn same TO THE LEFT to decrease the end play. If too tight, turn to the right. You will find these directions, or their equivalent, stamped on the nut itself.
END PLAY IN CAM. This may be overcome as follows: Remove entire movement from the mechanism — see instruction No. 2, page 708. Lay on bench and remove knurled knob from end of flywheel shaft by turning to the RIGHT. Caution : This nut is locked to the shaft by means of a small set screw in its edge. Loosen this before attempting to remove the knob from the shaft. Having removed the knurled knob, pull flywheel from shaft.
Next remove the six screws which hold the cover of the oil well, and remove the cover. WARNING: In removing cover of oil well, be careful and do not injure the paper gasket upon which it seats. Next loosen, but do NOT remove, screw in the knurled collar on the end of the cam shaft. With the fingers of the left hand, hold the cam itself, inside the oil well, while you turn the knurled collar on the end of its shaft to the RIGHT until the desired adjustment is had, which will be when the cam turns freely, without either friction or end play to its shaft.
NOTE. — By loosening the locking screw in knurled collar on end of fly wheel shaft and turning knurled nut to the right, this adjustment may also be accomplished, but it is strongly recommended that the plan above set forth be followed.
WARNING AND CAUTION.— -Whenever it becomes necessary, for any reason, to remove the oil well cover, the relation of the star and cam MUST be fixed in accordance with the previous instruction titled "TO ADJUST THE MOVEMENT." Do not neglect this warning unless you are looking for trouble.
