Maintenance
Maintenance Adjustments
Certain components of the paver need adjustments
for optimum performance, operation and general
maintenance.
Entanglement hazard! DO NOT run
the engine while checking and servicing conveyor
components. NEVER perform any adjustments while
the engine is running.
Conveyor Flight Chain
The conveyor ight chains must be adjusted every 100
hours. If irregular movement of the conveyor occurs, an
adjustment is needed regardless of the time interval.

2 - Locking Nut
3 - Hold-Down Nut
There are four (4) adjustment bolts, two (2) for each
conveyor. Use the following procedure to make this
adjustment on both sides of the conveyor:
1. Raise conveyor bed and insert safety prop. (Page
5-4)
2. Loosen the hold-down nuts (one on each side of
each adjustment bolt). (Figure 5-6)
3. Loosen each locking nut beside the adjustment bolt.
4. Turn each adjustment bolt alternately the same
amount. For example, turn one bolt one half turn,
then the other bolt one half turn, etc.
5. Continue alternating tightening until the ight
chains are tight. (The pressure on the chain will be
noticeable as the bolts are tightened.)
6. After the conveyor chain tension is set, retighten
locknuts and bolts holding the ight chain assembly.
NOTE: If the adjustment bolt has reached its
maximum adjustment level, remove two links
in the conveyor chain and add a half link. This
repair should bring the adjustment bolts back
to full travel.
Keep conveyor ight chain properly
oiled with cleaning solvent or release agent during
cold weather to keep conveyors functioning
smoothly.
Conveyor Drive Chain
Keep chains clean, lubricated. and properly adjusted.
Inspect both drive chains at the rear track. If the chains
are loose, adjustment is necessary.
1. Shut off paver.
2. Open engine access door on the side to locate the
conveyor drive chain bolts. (Figure 5-7)
3. Loosen the jam nuts on the chain adjuster.
4. Turn the chain adjuster to loosen or tighten the
chain, leaving approximately 1/4-inch of slack. DO
NOT overtighten.
5. Retighten jam nuts.
6. Repeat steps on the opposite conveyor drive chain.
