If your Lincoln Water Pump isn't operating, ensure that the air pressure supplied to the pump is adequate for operation. Also, the muffler could be clogged. Try removing the muffler and cleaning or replacing it.
What to do if Lincoln A 274217 operates but does not deliver lubricant?
If your Lincoln Water Pump operates but doesn't deliver lubricant and won't stall when the control valve is closed, there might be several reasons. First, check if the lubricant reservoir is empty or low and refill it if needed. Second, an air pocket may be present in the lubricant; try repositioning the pump or removing the air pocket. Also, inspect the check valves (21 & 27) for dirt, wear, or damage, and clean or replace them if necessary. Finally, the plunger (18) could be worn or damaged, requiring disassembly of the pump and replacement of the plunger (18) and pump bushing (25).
Why is lubricant expelled from the exhaust muffler of my Lincoln A 274217 Water Pump?
If your Lincoln Water Pump is expelling lubricant from the exhaust muffler, it could be due to water in the air or high humidity conditions. Installing an air filter and lubricator in the airline to the pump can remove moisture and lubricate the pump. Another possible cause is a damaged or worn upper U-cup seal (12) or piston rod (8), which would require repair or replacement as needed.
What causes air to leak from the exhaust of a stalled Lincoln A 274217?
If air leaks from the exhaust when your Lincoln Water Pump is stalled, it could be due to damaged or worn air piston (5), piston seals (4), or air cylinder (2); replace any damaged components as needed. Alternatively, broken return springs (7 or 30) could be the cause, requiring their replacement.
