LUBRICATION & MAINTENANCE CONTINUED
If, after continued adjustment, the belt does not track properly, check the following:
1.
Check for twisted spreader body. Shims must be placed between spreader cross tubes and the
mounting surface to eliminate any twist in the body structure.
2. Check for crowned Idler Pulley by placing a straight edge on the pulley. If properly crowned, the
straight edge will contact the center pulley leaving 1/16 inch gap between the straight edge and both
pulley ends. Replace the pulley if crown is not present.
3. Check for lacing squareness by removing the belt. This should be done as a last resort. If the
lacing is not square to the belt ends, contact your dealer for service.
4. Sight down the body under the belt shields. The only point which should come close to or slightly
contact the belt, is the lowest point on the shield. If the belt contacts the shield firmly at any other
point, tracking will be impossible and you should see your dealer immediately. Only your dealer
can correct the situation.
Shield
The belt shields along each side of the belt inside the unit should be just contacting the belt when the
belt is properly adjusted and the unit is empty (Figure 14). If a shield has clearance along its length, it
can be moved down until it just contacts the belt by loosening the fastener bolts, allowing the shield to
slide downward and tightening the bolts. If the shield is tending to cut into the belt along its full
length, loosening the bolts and raising the shield until it just contacts the belt will correct the problem.
If the shield cuts the belt at one or more points or if it gaps at one or more points, it should be replaced.

Don’t lubricate the #5 belt. Use of lubricants will cause the belt to deteriorate
and fail prematurely.
