Location and Description of Major Components (cont)

TM 5-3610-286-20 (f) Roller guide rail assemblies. Located inside both drive and operator’s side frames. Hold rider rollers in ink unit. (g) Oscillator lever assemblies. Located behind guard on drive side of printing press. Control lateral movement of oscillator rollers through a series of levers driven by driving mechanism. (h) Swivel lever assemblies. Located on operator’s side frame behind upper guard. Contain form roller journal boxes and aid in positioning form rollers to plate cylinder. (i) Journal box housing assemblies. Located inside operator’s and drive side frames. Contain journal boxes and adjusting mechanisms and control form rollers’ position. (j) Driving mechanism. Located on drive side frame. Supplies mechanical power to oscillator rollers and oscillator lever assembly. (k) Vibrator roller bearing assembly. Located on operator’s and drive side frames. Holds inking vibrator roller. During operation, vibrator roller bearing shaft is controlled by a cam and pull rod in driving mechanism. (l) Roller adjusters and feeler rods. Located on operator’s and drive side frames. Roller adjusters are worm gears which position the form rollers by moving journal box housings. Feeler rods are spring-loaded rods that rest in journal box housing on drive side of printing press. They are used to adjust for the bounce of the form roller as it paces the clamp on plate cylinder. (m) Ductor roller swing mechanism. Located on operator’s side frame behind upper guard. Controls amount of dwell in ink fountain roller. (n) Upper oscillator roller and bearing. Located between manual inking roller and ink ductor roller. Controlled” by driving mechanism and oscillator lever assembly. (o) Distributor roller latch assembly. Located on side frames. Holds manual inking roller in place during operation. (4) Dampening group (04). (a) Dampening rollers. Located between side frames. Five rollers move dampening solution in metered amounts from dampening fountain to printing plate clamped to plate cylinder. (b) Vibrator roller and bearing assembly. Located between dampening fountain and oscillator roller. Movement of this dampening roller is controlled by dampening cam lever through use of a shaft and spring rods. (c) Engaging lever assembly. Located on drive side frame behind main guard. Positions dampening rollers for impression-ON operation. (d) Dampening fountain assembly. Dampening fountain is heId in position on feeder end of press by guide pieces on both side frames. Holds dampening solution supplied from solution container. (e) Dampening oscillator bearing assemblies. Located in operator and drive side frames. Hold dampening oscillator roller and control its movement through oscillator lever assembly and driving mechanism. 1-7
