Maintenance & Adjustments

Level Wind Timing

The machine must be med prior to rst run!

1. Pull all the irrigaon tube out from the Water-Reel. The elbow to which the tube is fastened must be 45

degrees behind the axle centerline on the boom of the spool (See levelwind ming diagram). Be espe-

cially careful not to pull the tube o the elbow.

Cauon! Never aempt to reme the Water-Reel without rst pulling all the tube out.

Changing the ming with some of the tube sll on the spool may result in damage to the

irrigaon tube and/or the Water-Reel.

2. Remove the levelwind fork (4 bolts).

3. Observe the posion of the levelwind carrier drive lug master link on the horizontal levelwind chain. (The

chain that runs le to right just behind of the compensaon bar). The drive lug must be in its most ex-

treme posion (half way around the sprocket and on the same side of the Water-Reel as the spool elbow

(see video and diagram). If it is not the machine is out of me.

4. To adjust ming, remove the levelwind gearbox shield and cap screws from the levelwind input sprocket.

DO NOT REMOVE THE SPROCKET. Rotate the hub of the gearbox sha unl the drive lug is posioned as

described in step #2. Re-install the cap screws in the new posion. Reinstall the levelwind drive chain

shield and fork.

Drive Roller Adjustment

If the drive system has been disassembled, it will be necessary to adjust the mesh of the ring gear teeth to the

gearbox drive roller. The ring gear is a large part that will not be perfectly concentric. Tape or x a felt p

marker to a frame member and rotate the drum with the marker touching the outside face of the main gear.

This will mark the point in which the ring gear teeth are closest to the drive roller. Rotate to this point on the

ring gear so it is exactly at the drive roller. The clearance is adjusted by moving the clamps that fasten the

gearbox mount to the frame of the Water-Reel. Lower the gearbox unl the drive roller just contacts the

crotch of the teeth of the ring gear, then ghten the gearbox mounng bolts. A scissor jack is ideal for raising

& lowering the gearbox. Rotate the spool to be sure the roller to ring gear seng is correct with no interfer-

ence.

Pinion Drive Roller

Point on ring rear that is closest to pinion drive rollers.
