Automatic Greasing System Difficulties

Never work on machine while it is running. Driveline can continue after disengaging PTO. Stay clear of machine until it has come to a complete stop. Shut engine off, remove key from ignition, set parking brake, and engage flywheel brake before repair or servicing.

Only restart machine once cause is identified and resolved. Working with an unsafe machine can result in serious injury or damage to equipment.

If lubrication points have been dry for an extended period, purge system using bypass lubrication fitting at main divider block or at each secondary divider block until sufficient lubrication appears.

Automatic Greasing System
Problem	Cause	Solution
Pump does not work.	Electrical harness broken.	Repair or replace electrical harness.
	Electric motor broken.	Replace motor.
	Fuse blown.	Find cause and replace fuse.
Pump works, but no grease output.	Air bubble in pump plunger.	Bleed pump. (See Bleed Automatic Grease System in Service section.)
	Grease level in reservoir below minimum.	Refill reservoir with recommended grease. (See Multiluber Grease in Lubrication and Capacities section.)
	Pump piston broken.	Replace pump piston. See your John Deere dealer.
	Motor runs in wrong direction (see arrow on reservoir).	Change polarity of wires to pump motor.
	Overflow tube is blocked.	If reservoir has been overfilled, a vacuum inside reservoir can be present and will hold grease in reservoir. Clean overflow tube.
All lubrication points are dry.	Pump not working.	Replace pump piston. See your John Deere Dealer.
	Grease system setting too low.	Increase grease system setting using ISOBUS display.
	System is blocked.	Check for grease at pressure release valve.
Several lubrication points are dry.	Lines to divider blocks broken or leaking.	Repair lines as necessary.
	Compression couplings leaking.	Tighten or replace compression couplings.
Several points in one area of machine are dry.	Line from primary divider block is leaking or broken.	Remove secondary supply line from divider block and cycle pump. If no grease is present, repair or replace line.
	Fitting is leaking at secondary divider block or inlet.	Check fittings for leakage. Repair or replace fitting as necessary.
One lubrication point is dry.	Line is broken or leaking.	Repair lines as necessary.
	Compression coupling leaking.	Tighten or replace compression coupling.
Grease at the output of the pressure release valve.	System pressure too high.	Test the system.
	Divider blocked.	Repair or replace divider block. See your John Deere dealer.
	System blocked.	Repair blocked or failed bearings.
	Spring in pressure release valve is broken.	Replace pressure release valve.
Pump rotates slowly.	High pressure in system.	Check pressure relief valve for grease. If no grease is present, loosen each secondary divider block inlet fitting one at a time. If pressure relieves at fitting, check individual points for restrictions. Clear restriction from line.
	Extremely cold temperatures.	Clean out reservoir and fill with low temperature grease or grease of lower NLGI rating. (See Multiluber Grease in Lubrication and Capacities section.)

If grease alarm appears on monitor, first check the following:

• Presence of grease in reservoir.
  • Fill reservoir with recommended grease. (See Multiluber Grease in Lubrication and Capacities section.)
  • Bleed system if necessary. (See Bleed Automatic Grease System in Service section.)
• Visually check to see if pump is running. Grease agitator will constantly stir contents in reservoir while machine is in operation.
  • Check grease settings.
  • Check power connections.
  • Check for correct drive direction (arrow on container).
