the bearing hanger. Slide on one lock collar,
bearing and bearing flangettes. Installthe 19
tooth sprocket and second lockcollar. Slide
shaft back into position, then slide couplers
backinto position. Check to see if shaft is cen­tered in the bearinghanger opening. Loosely
attach bearings flangettes, then tighten the
four mounting bolts on the controller/motor.
Tighten bearing flangettes.

Note:Shaft should nowturnfreely byhand with no
bindingat the shaftcouplers.If thisisnotthe case,
the drivemount isnot properly positioned on the
gusset. Tocorrect this, enlarge the mounting
holes to allow the mount to be moved forward or
backwardto properly alignthe mountwith the piv­ot shaft.

Once the mountis properlyaligned with the pivot
shaft,reinstall the shaft couplers with 1/4” x1 3/4”
bolts and 1/4” lock nuts.

with one bearing onto the shaft. Install the
speed sensor disc with one lock collar on
each side. Do not tighten lock collars.

14. Remove the forward boltfrom theoutside
bearingandreplace it witha5/16" x 13/4"bolt
and 5/16" nut and tighten. Place the spacer
on the bolt then mount the sensor bracket on
the bolt. Secure bracket with a 5/16" nut.

15. Screw the sensor into thesensor mount until
there is a .030 clearance. Lock sensor in
place with the jam nut. Move the sensor disc
so it aligns with the sensor and secure it in
place with the lock collars. Route the cable
along the contact wheel arm and up to the
controller/motor mount. Repeat steps 13
through 15 to install the Verissensor and sen­sor bracket on the right-hand drive.

the bracket installed on the left-hand drive.
Properly adjustclearance. Tie bothcables to
the contact wheel arm, and make sure they
are routed to prevent pinching.

Note: You can not leave the seed monitor speed
sensor on the pivot shaft or the sensor will be
reading motor drivespeed instead offield speed.
It is not necessaryto movethe sensor disc for the
seedmonitor.Theseed monitorcanusethe same
sensor disc as the Veris sensor.

Note: After relocatingthe seed monitor speed
sensor it will be necessary to calibrate the
monitor. Refer to the DICKEY-john® manual
for monitor distance calibration instructions.
