Check generation: Some pre-2014 units use earlier pumps; confirm your pump model number before purchase.

Install & Service Tips

Depressurize, flush, and remove the pump per your manual before disassembly.
Inspect piston rod and packings; replace worn items to protect the new cylinder.
Lubricate packings properly and torque to spec; pressure-test after reassembly.

Frequently Asked Questions

Check the sprayer model and the installed pump assembly. If your pump is one of 17C487 / 17C488 / 17C489 / 17C721 / 17M992 / 24Z731, or your sprayer is listed above in Compatible Machines, the 24W619 is the correct cylinder. For older (pre-2014) units, verify in the parts manual by serial number.

Rapid packing wear, pressure fluctuations, poor priming, or scoring visible on the bore are common signs. If the bore is scratched or out-of-round, replacing the cylinder is recommended along with packings.

It’s good practice to inspect/replace upper & lower packings, check balls/seats, and the piston rod if worn. This protects the new cylinder and restores full performance.

This listing is for the cylinder itself. Seals, packings, or complete pump kits are sold separately unless specified otherwise on the product page.

Generally no. Pre-PC pumps used earlier cylinder designs. If your unit predates the PC / PC Pro update, confirm by pump model or consult the parts manual for your serial number.
