Troubleshooting - 6644 Grain Vac

Troubleshooting

The heart and lungs of the Grain Vac are the airlock and the blower (air pump). Both components must be operating at their recommended speed to obtain maximum efficiency from the machine.

The blower is driven by a belt and pulley system from the drive system attached to the engine. The airlock is driven by a hydraulic motor that is attached to the diesel engine.

If you encounter a problem that is difficult to solve, even after having read through this trouble shooting section, please call your local dealer or the factory. Before you call, please have this

Operators Manual and the serial numbers from your Grain Vac ready.

In North America call (204) 822-4467

Problem

Low capacity

Excessive grain damage.

Cause

Belts are slipping.

Airlock runs too fast.

Solution

Tighten belts.

Slow down airlock speed until grain builds up to the level of inspection door.

Adjust air intake.

Improper air intake.

Improper use of nozzle.

Air leaks - Intake.

Air leaks - Machine.

Improper piping.

Use full bin nozzle for larger piles and full bins. Use cleanup nozzle with flair for cleanup only. Do not submerge airslide in grain.

Check for worn coupler levers or missing coupler gaskets.

Check BPS, receiver section, and airlock gaskets.

Check pressure and vacuum relief valve.

Check clamps on airline between receiver tank and BPS and between BPS and blower.

Keep suction lines as short as possible.

Minimize bends.

Use straight length of pipe wherever possible.

Use the poly hose for clean up only!

Airlock tip clearance high.

Airlock end plate clearance

Adjust airlock tips.

If rotor to end plate clearance is more than 0.015", consult the dealer or factory.

Too much air intake.

Adjust air intake nozzle.

Blower running too fast. Throttle down engine.

Damaged tubing or flexline.

Repair or replace.

Insufficient grain supply. Reposition nozzle.

Troubleshooting - 6644 Grain Vac

Problem

Pulsation

BPS plugs

Airlock not turning at all.

Cause Solution

Insufficient air at intake. Open slide until grain flow becomes even.

Airlock turning too fast.

Improper piping.

Adjust airlock speed until grain is at level of the inspection door.

Replace steel flex or poly hose with rigid tubing wherever possible.

Suction line too small.

Use proper line size.

Engine running too slow. Increase engine RPM to recommended speed.

Belts are slipping.

Excessive airlock tip clearance.

Tighten belt.

Adjust airlock tips.

Airlock turning too slow.

Adjust airlock speed until grain is at the proper level on the inspection door.

Obstruction in suction.

Shut down machine and clear line obstruction.

Airlock turning too slowly.

Airlock turning too fast.

Airlock not turning.

Flow control valve wrong.

Increase airlock speed until grain is at the proper level on the inspection window.

Decrease airlock speed until the grain is at the proper level on the inspection door.

Check for and remove obstruction in airlock

Reset flow control.

Obstruction in airlock.

Shift Forward/Reverse lever from FORWARD to REVERSE and back to FORWARD. Repeat if obstruction does not clear up. If obstruction does not clear up, shut off engine, open inspection door and remove cause of obstruction.

Hydraulic oil heating up excessively.

Low oil level.

Add oil.

Excessive wear on air lines.

Improper piping.

Too much air flow.

Minimize bends.

Adjust airslides and airlock speed.

Insufficient grain supply. Reposition intake nozzle. Open grain supply doors.

Excessive engine speed. Operate at proper recommended engine speed.

NOTE: Also reference the Cummins Diesel Manual, Twin Disc Clutch Manual and Dexter Manual for proper troubleshooting instructions.

Storage - 6644 Grain Vac

Storage

Prior to storage we recommend that you thoroughly inspect your Grain Vac.

1. Replace any worn or damaged components.

2. Wash and clean the machine. After cleaning, run machine at low idle for 2-3 minutes to dry the internal components.

3. While machine is running at an idle, open the cleaning port and inject a cleaning agent such as WD40 for 45 - 60 seconds.

This will coat the inside of the air pump to help prevent rusting.

4. Lubricate all grease points. Make sure all grease cavities have been filled with grease to remove any water residue.

5. Retract and stow all components and accessories and install cover over the boom pivot. (Keeps out dirt and small animals).

6. Inspect all hydraulic hoses, couplers, fittings and lines. Tighten any loose fittings.

Replace any hose that is badly cut, nicked, abraded or is separating from the fitting.

7. Inspect, clean or empty the BPS.

8. Check the fluid level in the air pump oil reservoirs. Add oil as required.

9. Touch up all paint nicks and scratches to help prevent rusting.

10. For storage, select an area which is dry and level. Make sure unit is firmly blocked and will not tip or sink into a soft area. Place a plank under jack for added support.
