SPACEBAND TROUBLES
Transposition troubles of the spacebands may be caused by any of the following: Worn keyboard cam roll, keyboard cam sluggish, loose keyboard driving belt, keyrod spring weak, tongue at the bottom of spaceband chute bent too far, worn star wheel, pawl levers loose on the shaft, caused by taper pins not being tight; dirty spaceband box pawls, pawl levers not adjusted properly, worn pawls and rails, chute spring out of adjustment, chute rails worn; also on the cam frames with the spring bar, a weak keyboard cam yoke spring.
Some of the causes for the spacebands not dropping are: Worn rails or pawls, lifting screw holes in pawls worn, bent spacebands, bent ears on spacebands, center bar out of adjustment, keyrod spring weak or off, dirty spaceband box pawls, weak pawl springs, worn rubber roll, free end of keyboard cam yoke gummy, pawl lever loose. On the cam frames with the spring bar, the cam yoke spring too tight; bent hinge rod on cam yoke or trigger dirty, or anything else that would prevent the free movement of the pawls.
Spacebands travel through the machine suspended by their lugs. Constant use causes the under side of the lug to wear, and when spacebands with badly worn lugs are mixed together with new spacebands, difficulty frequently arises and they occasionally clog in the chute when released by touching the spacebar. The only remedy is to send the offending spaceband to the factory to be repaired.
