MODEL 3680 HYDRAULIC SECTION
THE BEAST RECYCLER HYDRAULIC SYSTEM
The Beast Recycler is equipped with a very efficient,
simple hydraulic system. Each component is capable
of withstanding its specified PSI (bar) and still operate
for a very long time.
If you follow the simple rules mentioned below, the
hydraulic components will last for years:
• Avoid hydraulic pump cavitation. Low oil levels or
cold start-ups will cause the hydraulic pump to
cavitate. Cavitation will ruin the pump and possibly
the entire hydraulic system. Cavitation only has to
happen once. This will start the pump on its way to
ruin. Allow hydraulic system to turn slowly for
several minutes in cold weather in order for
hydraulic system to warm up. Cavitation is not
covered under warranty.
• Do not operate the machine if the hydraulic oil level
is low. This will cause the pump to cavitate and
over heat. Keep tank minimum 7/8 full.
• Do not increase the relief valve settings beyond its
specified PSI (bar). This will cause damage to
hydraulic or mechanical components.
• Keep your oil clean, dirty oil will cause excessive
wear and loss of feedwheel power. Replace spin on
filters per maintenance chart.
• Replace the hydraulic oil suction screen & oil filters
with each 400 hours of operation or 3 months.
• Replace your hydraulic oil once yearly. This is also
a very good time to flush and clean the tank.
• If you keep the recycler’s hydraulic system clean
and do not increase the hydraulic pressure beyond
specified PSI (bar), you will get the maximum use
and life out of your recycler.
• If you encounter a problem, it will more than likely
be located in the relief valves or something as simple
as pump belts slipping. Make sure all Hydraulic
Shut-Down Switches are pulled out.
• Always check these areas first.
PROCEDURE FOR CHECKING HYDRAULIC PUMP
AND RELIEF VALVE SETTING
All hydraulic circuits have a diagnostic port located in the valve banks, there are a total of five. Each machine is
delivered with a 3000 PSI (207 bar) gauge installed in the diagnostic port of the valve bank on the upper right hand
side of the control cabinet. Before checking any pressures the hydraulic oil must be at normal operating
temperature. Also remember to relieve any pressure in the hydraulic system before disassembly. Checking these
pressures will be done with engine operating at full RPM’s so the Recycler must be secured. Allow no one on or
near the machine while performing these tests except the operator. The test are all completed at the control panel
on the left hand side or road side of the machine.
Starting with the valve bank on the bottom of the control cabinet. This valve bank has manual controls for the
Infeed Conveyor, Feedwheel rotation, Feedwheel Yoke, and the Concave Door. There are three diagnostic ports in
this bank, one for the Infeed Conveyor, one for the Feedwheel rotation, and one for both the Feedwheel Yoke and
Concave Door.
Before checking the Infeed Conveyor Chain or the Feedwheel rotation circuits you will need to disconnect the
hydraulic hoses at the drive motor and cap them. This is necessary to cause a restriction so you can check the
system pressure. Remember, never work on or near the Feedwheel without Yoke Lock Bars and Safety Chains in
place. The Feedwheel must be down before testing hydraulic system pressure. Also make sure the flow controls
for the Infeed Conveyor and the Feedwheel systems are closed so no oil is being drained back to tank.
