Maintenance & Adjustments
Level Wind Timing
The machine must be timed prior to first run!
1. Pull all the irrigation tube out from the Water-Reel. The elbow to which the tube is fastened must be 45
degrees behind the axle centerline on the bottom of the spool (See levelwind timing diagram). Be espe-
cially careful not to pull the tube off the elbow.
Caution! Never attempt to retime the Water-Reel without first pulling all the tube out.
Changing the timing with some of the tube still on the spool may result in damage to the
irrigation tube and/or the Water-Reel.
2. Remove the levelwind fork (4 bolts).
3. Observe the position of the levelwind carrier drive lug master link on the horizontal levelwind chain. (The
chain that runs left to right just behind of the compensation bar). The drive lug must be in its most ex-
treme position (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 time.
4. To adjust timing, remove the levelwind gearbox shield and cap screws from the levelwind input sprocket.
DO NOT REMOVE THE SPROCET. Rotate the hub of the gearbox shaft until the drive lug is positioned as
described in step #2. Re-install the cap screws in the new position. 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 fix a felt tip
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 until the drive roller just contacts the
crotch of the teeth of the ring gear, then tighten the gearbox mounting bolts. A scissor jack is ideal for raising
& lowering the gearbox. Rotate the spool to be sure the roller to ring gear setting is correct with no interfer-
ence.
