REMOVAL OF TINE DRIVE HYDRAULIC
MOTOR, HUB, AND MOTOR MOUNT
1. Remove tine cover #1008 (twelve 5/16 X 1 bolts).
2. Remove left bank of tines (4 tines closest to hydraulic motor).
3. Remove the 3 bolts (3/8 X 1) that hold the right side plate (#1007) in place.
4. Remove the tine shaft (#1011), bearing (#3043), and side plate (#1007) from the tine motor
hub (#1010). If it does not slip off easily, use a lead shot hammer on the center flange of the
tine shaft.
5. CAUTION: DO NOT PRY BETWEEN HUB AND TINE SHAFT FLANGE.
6. To remove the tine motor hub from the motor shaft: with pulling collar (#2019) in place,
insert snap ring (#3041) in the hub groove and remove with puller. The hub may be very
tight and require heat or penetration oil to free it from the motor shaft. Extreme cases may
need to be removed with a cutting torch.
7. Remove hydraulic hoses from motor.
8. Remove tine motor guard (4 bolts) and motor mount bracket (remaining 4 bolts) and slip
motor out. Then, remove motor from mount bracket (four 1/2 X 1 1/2 bolts).
9. On older motors, remove dirt shield from face of motor. To remove screws, first heat screw
heads with torch to melt the Loctite. Remove screws with 1/8” Allen wrench.
10. Motor is now ready to be serviced. Follow steps outlined in Char-Lynn repair manual for
2000 series motor.
REINSTALLATION OF TINE DRIVE HYDRAULIC MOTOR
1. After motor is assembled, slip felt washer over the shaft. Slide steel dirt shield over and line
up holes. Place a drop of Loctite 271 (red) on-each screw and tighten. Newer motors have a
seal guard and do not require a felt washer nor dirt shield.
2. Bolt motor mount frame to the motor with bolts.
3. Place key in shaft slot and slide on new tine motor hub.
4. Tap hub in place with lead-shot hammer or block of wood. Place 2 drops of Loctite on bolt
and tighten.
5. Check hub with dial indicator for run out. Run out should be less than .003" on outer
diameter of hub face. With tine shaft bolted to hub, run out on shaft at outboard bearing
should be .015" or less.
