Troubleshooting instructions for Low Level and Lube Faults with Lincoln’s 653 Pump

Which Are You Experiencing?

Select your error message to be taken to your trouble shooting instructions.

Low Level Fault

Level of lubricant in the reservoir is low and additional lubrication needs to be added.

Lube Fault

System fails to relieve pressure in the user-defined amount of time.

Pump / GreasePoint Monitor Shows Low Level Condition

What does this mean? Level of lubricant in reservoir is low and additional lubricant needs added.

How do I fix / reset? 

  1. Fill pump reservoir from fill fitting on front of the reservoir or via ground level filling port if provided. 
  2. Manually cycle the pump either from a remote run button in the cab, or via the push button on the pump cover circuit board (press and hold for 4 seconds).
  3. Verify the paddle turns, see the cycle pin moves on the primary valve – verify that the low level signal on GreasePoint’s monitor disappears. 

Lube Faults

Connect ignition or machine switch per electrical schematic on pages 28 and 29

Pump with follower – refill reservoir. Pump without follower – refill reservoir and push switch (pg. 18, Fig. 15) to initiate manual lube cycle. 

Push switch (pg. 18, Fig 15) to acknowledge fault. Initiate manual lube cycle. Investigate and correct possible causes – air pockets, broken lines, connections leakage, worn pumping element, failed internal pressure switch or pressure transducer. Initiate manual lube cycle.

Push switch (pg. 18, Fig 15) to acknowledge fault. Initiate manual lube cycle. Investigate and correct possible causes – air pockets in lubrication line, connections leakage, grease consistency changed with low temperatures, failed end of line pressure switch or pressure transducer. 

Push switch (pg. 18, Fig 15) to acknowledge fault. Initiate manual lube cycle. Investigate and correct possible causes – pump eccentric did not stop in a proper position, vent valve failed. 

Push switch (pg. 18, Fig 15) to acknowledge and correct possible causes – restriction in lubrication line, grease consistency changed with low temperature, failed end of line pressure transducer or pressure switch. 

Check and adjust setting of pressure transducer of failed pressure switch (pg. 6, Fig 1).
