ARO 637083 Lower End Repair Kit
Lower end (fluid section) repair kit listed for the ARO 612041-3 drum oil pump and the 612042-1 pump.
Rebuild the lower end of an ARO 612041-3 or 612042-1 pump with the 637083 repair kit. Compare it with 637081, which is listed for the same pumps.
ARO 637083 is a repair kit for the lower end of the 612041-3 and 612042-1 pumps. On a piston pump, the lower end is the fluid section, where the pump tube, plunger and check valves move the product. The 612041-3 model is a 1:1 ratio pump for oil in 55 gallon drums.
The spec table describes 637083 only as a service kit and does not list its parts. Our catalog also carries ARO 637081, a second lower end kit tied to the same two pumps. Your pump manual's parts list shows which number covers the repair you plan.
When to Use This Kit
- Output from the drum pump has dropped even though the air motor runs normally.
- Oil leaks at the lower end or seeps back into the drum when the pump stops.
- The pump runs fast on the downstroke, which often points to a check that no longer seals.
