Before using the cart for the season:
1.
Exercise the disconnect handle, adding a lubricant to the 2" output shaft on the first gearbox where the grooved spline coupler
slides. Loctite Silver Grade Anti-Seize is recommended.
2.
Check the face of the disconnect paddle for excessive wear (1/32" or more). In the event of excessive wear (1/32" or more), contact
the J&M Service Department.
Disengage Paddle, and Back Plate Settings
The back plate has a tab welded on the inside with a nut. A bolt and jam nut are screwed into it. The proper bolt setting maintains the
gap shown in the bottom right picture. The paddle is shown in purple here, and when the drivedogs are engaged there should be a
1/16" gap between the paddle and the drivedog. Having the gap will ensure that there is no unnecessary wear on parts.
Bolt and Jam Nut
IMPORTANT: When the grain cart is not in use, store the cart in a dry, protected place. Leaving your grain cart outside, open to the
weather will shorten its life.
Procedure for Storage Preparation
1.
Cover electronic monitor (if equipped) with plastic before washing the grain cart. Wash or clean and completely lubricate the grain
cart. See "Lubrication Service Schedule" on page 15.
2.
Remove all grain from inside the grain tank, auger tube assemblies, and at the clean-out door.
3.
Check the gearbox oil and replace with new SAE 80W-90 gearbox lubricant or equivalent if necessary.
4.
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.
5.
Retract all hydraulic cylinders to prevent the piston rods from rusting.
6.
Open the clean-out doors at the base of the grain tank.
Removing from Storage
1.
Check the gearboxes to make sure they have the appropriate amount of oil.
2.
Close the clean out doors at the base of the grain tank.
3.
Make sure all safety shields are in the proper position.
