Troubleshooting

Locating Blockage in Lincoln Quicklub® Systems

Description In a Lincoln Quicklub® Lubrication System, free flow of lubricant from the pump through the transmission system and the bearings is necessary. If any portion of this transmission system (a divider valve, line fitting or any bearing) does not freely accept and pass its portion of the lubricant a blockage has occurred. This blockage will cause a higher than normal pumping pressure to be developed by the pump. Depending on the application or system design, this blockage with its resultant high pump pressure will usually cause a complete loss of lubricant flow into the total system and no bearing will be receiving lubricant. The loss of flow due to a blockage is first indicated with the higher than normal system pressure that is developed by the pump as it attempts to overcome this blockage.

This abnormally higher pressure that is a result of a blockage is limited, isolated, and signaled through the use of various performance indicators, reset and relief, incorporated into the system design.

Divider Valve A Quicklub® divider valve is a proportioning device consisting of a minimum of three pistons. A primary divider valve is the first divider valve downstream from the lube pump. A secondary divider valve is any divider valve receiving lubricant from the primary divider valve.

Outlets Each outlet on a Quicklub® divider valve dispenses .012 in³ per cycle. If an outlet is plugged, the lubricant will be diverted to the next outlet down allowing proper proportioning of lubricant to all lubrication points.

Warning — Never block lube outlets numbered one and two.

Locating Blockage If a blockage exists in a Quicklub lubrication system it is caused by one of the following reasons:

  • (1)

    Crushed transmission line in the System.

  • (2)

    Blocked bearing in the system.

  • (3)

    Improperly drilled fitting in the system.

  • (4)

    Blocked divider valve in the system.

All servicing and disassembling should be carried out under the cleanest conditions possible. A blockage in a Quicklub system will be indicated by the fault light and by the pump element relief indicator, exhausting lubricant to atmosphere. Before proceeding as outlined, make a visual inspection of the system and check for crushed lines or improper divider valve installation. Verify that each divider valve outlet required to discharge lubricant can do so and that no plugs have been installed in an outlets one and two of any valve.
