Lubrication
Your gravity wagon has grease fittings at all critical points. These should be serviced before the gravity wagon is put into
operation each season.
HOW TO FLUSH OLD OIL OUT OF THE OIL BATH HUBS
Your gravity wagon is equipped oil bath hubs. Follow these steps to flush the oil bath hubs once per year.
1. Check the hub for leaks and wear. Replace components as necessary.
2. Roll the hub until the fill plug is on top.
3. Drain the hub by removing the cap.
4. After draining the old oil, use light weight motor oil to flush out remaining oil. There is no need to tilt the hub, the oil will flow
through the bearing easily.
5. Replace cap. Torque cap to 30-40 ft-lbs.
6. Replace oil with 80-90WT Sta-Lube from NAPA. This oil has a rust inhibitor additive.
HOW TO ADD OIL TO OIL BATH HUBS
IMPORTANT: Use Napa STA-Lube - GL5 80/90 WT with Rust Inhibitors FL2472 for the Oil Bath Hubs.
1. Use a 3/4” wrench to remove breather plug.
2. Add 80-90WT Sta-Lube oil from NAPA with an oiler hand pump.
The recommended oil capacity in the hubs is 8 ounces.
3. Replace breather plug. First hand tighten, then use 3/4” wrench to make a 1/4” of a turn.
Routine Maintenance
WARNING: Ensure all power is shut off before servicing the gravity wagon.
•
Check the gravity wagon periodically for cracks in welds and for other structural damage. Fix cracked welds immediately. Failure to
do so could result in extensive damage to the gravity wagon and greatly reduce the life of the unit.
•
If equipped with uni-swivel auger, check all hydraulic hoses for wear and replace as necessary.
•
Ensure all tires are properly inflated. Refer to “Initial Operation & Maintenance” on page 11 for recommended tire pressures. It is
important that tires are inspected before and after unit loaded.
•
Ensure all grease fittings have proper lubrication.
•
Properly torque all lug nuts to 350 ft-lbs.
Your local, authorized dealer can supply genuine replacement parts. Substitute parts not provided by J&M Manufacturing may not meet
original equipment specifications and may be dangerous.
When performing maintenance work, wear sturdy, rough-soled work shoes and protective equipment for eyes, hair, hands, hearing and
head. Follow instructions in this manual to ensure safe and proper maintenance and repair.
Store the gravity wagon in a dry, protected place. Leaving your gravity wagon outside, open to the weather will shorten its life.
Follow the procedure below when your gravity wagon is placed in storage for periods up to six months:
1. Remove all grain from inside the grain tank.
2. Wash or clean and completely lubricate the gravity wagon.
3. Touch up areas where paint may have worn away. Use a good quality primer paint, especially before re-applying graphite paint to the
interior slopes of the grain tank.
4. Clean the tires before storage. Inflate the tires at regular intervals.
