Maintenance
Auger Drive Chain Adjustment
NOTE: Machine is off.
4. The auger chains should be just snug, not loose. To
tighten chains, loosen bolts (Figure 7-11,1,2) in slots
provided for take up.
5. To adjust chains for the right auger, use bolts
(Figure 7-11,1). For left auger adjustment use bolts
(Figure 7-11,2).
6. Use jack bolt under hydraulic motor mount to tighten
chain. Twist auger forward and rearward by hand to
feel play in chain (1/4 in. [0.6 cm] of play in chain is
recommended).
7. Tighten adjustment bolts to a torque of 209 ft. lbs.
(283 N•m).

Torque Hub Lubrication
NOTE: See 100-Hour or Monthly Routine
Maintenance in Section 7.
1. Position the torque hub so the center plug (Figure
7-3,1) is at the twelve o’clock position. Remove
the plug either at the three or nine o’clock position
(Figure 7-3,2). If oil comes out, no oil is needed.
Insert plug and tighten.
2. If oil does not come out, remove the plug at the 12
o’clock position and ll torque hub with specied
gear oil (see Specications in Section 4) until oil
starts to appear at the other hole.
3. Replace both plugs and repeat process on other
torque hub.
Track Tension Pressure Relief
Pressure Check
NOTE: Relief pressure is set at 700 PSI at track tension
manifold (Figure 10-1,43).
1. To check pressure, connect a 2000 PSI. gauge at
one of the hoses going to the track tension cylinder
(Figure 10-1,19).
2. Place a hydraulic jack between front idler (Figure
10-1,14) and track rail.
3. Back paver up slowly and observe gauge. Pressure
should go to 700 PSI. If pressure is not correct,
push idler back with jack or porter power that you
can monitor the pressure to see 700 psi. adjust
relief IN for more pressure and OUT for less
pressure.
4. Place a hydraulic jack between front idler (Figure
10-1,14) and track rail.
Track Tension Release
1. Locate manifold (Figure 10-1,43) under hopper to
release track tension.
Do not tamper with adjustment part of
relief cartridge.
2. Back relief cartridge out of the aluminum block
about three turns or until pressure release is heard.
3. Make sure cartridge is tightened before moving
paver.
