Tire Pressures
Inspect tire pressures and adjust
appropriately.
SPECIFICATION
Gauge Wheel Pressure:
Max 20 psi (140 kPa)
Drive Wheel Pressure
Max 20 psi (140 kPa)
Main Belt Tension
The main belt of the merger is automatically
adjusting, but requires occasional
maintenance to reset the spring.
Adjust the spring tension such that the black
bushing over the spring is loose so that it
can be turned but not moved laterally along
the spring. Use the jam nut to prevent the
adjustment nut from loosening during
operation. Adjust both sides of the belt as
required. See Figure 27.
Verify the main belt is clean and in proper
alignment on grooves and the frame before
and after tensioning.
Extension Belt Tension
The extension belt is adjusted manually and
must be adjusted regularly so the belt does
not sag more than 3/4" (19 mm) at the
bottom between the rollers.
To adjust the extension belt, first loosen the
four carriage bolts (Key 1, Figure 28) that
hold each adjuster plate in place.
Adjust the adjuster bolt (Key 2, Figure 28)
to move the roller in the desired direction for
belt tension.
When the proper belt tension is gained,
tighten all hardware properly.
