Steel Oil-End Piston for Vactor-Style Rodding Pumps

The UEMSI G39260 Oil-End Piston is a steel replacement piston for compatible Vactor 810, 1200, and 2100 Series rodding machines.

Manufactured to match the specifications of the compatible original part, this piston is installed on the oil end of the rodding pump. It is designed for municipal sewer departments, sewer cleaning contractors, and fleet maintenance shops repairing or rebuilding compatible Vactor-style pump assemblies.

A worn or damaged oil-end piston can contribute to reduced pump performance, abnormal operation, fluid leakage, or accelerated wear of related components. Inspect the complete pump assembly during replacement, including the piston rod, seals, cylinder surfaces, and associated hardware.

Fitment notice: Verify the machine model, pump configuration, existing part number, and piston dimensions before ordering. This product is the oil-end piston, not the water-end piston.

Replacement Considerations

Inspect the oil-end piston and related pump components if the equipment shows reduced performance, unusual noise, fluid leakage, scoring, or excessive internal wear.

During service, check the:

• Piston rod and cylinder surfaces
• Pump seals and packing
• Oil condition and contamination
• Retaining hardware and alignment
• Water-end components for related wear

Installing a new piston without correcting damaged seals, worn cylinder surfaces, contamination, or alignment problems may shorten component life.

Frequently Asked Questions

What is the UEMSI G39260?

The UEMSI G39260 is a steel oil-end piston for compatible Vactor 810, 1200, and 2100 Series rodding pumps.

Is G39260 an oil-end or water-end piston?

G39260 is identified as an oil-end piston. It should not be listed as a water-end piston unless your supplier provides documentation showing a different configuration.

Does G39260 fit every Vactor rodding pump?

No. Pump configurations can vary by machine model, year, and build specification. Verify the existing part number and pump configuration before ordering.

Are seals included with the piston?

Treat this product as the steel piston only unless the package or Range Supply inventory specifically states that seals or hardware are included.

Should other pump parts be inspected during replacement?

Yes. Inspect the piston rod, seals, cylinder surfaces, oil, packing, and related hardware. Damage or contamination elsewhere in the pump may affect the new piston.

Is professional installation recommended?

Yes. Installation should be completed by a qualified technician familiar with high-pressure rodding pumps and combination sewer cleaning equipment.
