5-12 LeeBoy Model 8510E Conveyor Paver
Maintenance
Track Tension Pressure Relief
The hydraulic adjustment cylinders are automatic and
provide even tension on the tracks to prevent excessive
wear to the paver’s undercarraige. The track tension
main manifold is mounted on the back side of the lower
hydraulic tank in the conveyor bed.
The track hydraulic pressure is set at 1500 PSI at the
track tension main manifold.
To check pressure, locate the track tension main
manifold in the conveyor bed and perform the following
procedures:
1. Raise conveyor bed.
(Page 5-4)
2. Connect a 2000 PSI gauge inline with either Port
A or Port B on the track tension main manifold.
(Figure 5-12)
3. Place a Porta Power between the front idler and
frame to release pressure on the idler.
4. Increase the Porta Power pressure until the front
idler cylinder compresses.
5. Pressure should read 1500 PSI.
6. If the pressure is not correct, remove cap on the
relief cartridge valve. Using an allen wrench, adjust
the relief cartridge valve IN for more pressure or
OUT for less pressure until the PSI gauge reads
1500 PSI.
7. When the pressure gauge reads 1500 PSI,
disconnect Porta Power and gauge.
Do not tamper with the adjustment
part of the relief cartridge valve.

Engine Maintenance
These general maintenance procedures are most often
required for the engine. Refer to the Engine Operator’s
Manual for more specific maintenance information and
procedures.
Check Engine Lubrication Oil
The engine lubrication oil must be kept at a level above
the ADD mark, but not above the FULL mark, on the
engine lubrication oil dipstick.
DO NOT check the oil while the
engine running. Hot oil can spew and cause serious
personal injury.

Figure 5-13. Engine Oil Dipstick and Oil Filter
To check the engine lubrication oil level:
1. Park the machine on a level surface and turn off the
engine.
2. Wait five minutes to allow the oil to return to the oil
pan so you can obtain an accurate measurement of
the engine oil level.
3. Clean the area around the engine oil dipstick before
removing it from the engine. (Figure 5-13)
4. Remove the dipstick from the engine and checking
the oil level. The oil level should be above the
ADD mark--but not above the FULL mark--on the
dipstick.
5. Add oil if needed.
