Titan 2423817A Pusher Stem Assembly

Titan 2423817A Pusher Stem Assembly

Sourced From:
Titan Tools Inc.

 

Titan part 2423817A is a complete pusher stem assembly used to transmit motion and pressure within the fluid section on compatible Impact X440 and X540i sprayers. When the original pusher stem becomes worn, bent, or damaged, it can cause inefficient pumping, pressure loss, and inconsistent spray performance. This assembly restores proper fluid delivery and reliable operation.

Assembly Includes:
  • Pusher stem shaft
  • Seals and packings
  • Retaining rings
  • Wear washers
  • Installation lubricant (if applicable)

Complete Pusher Stem Assembly for Impact X440 and X540i Sprayers

The Titan part 2423817A Pusher Stem Assembly is a critical component within the fluid section of Impact X440 and X540i sprayers. This assembly transmits mechanical motion from the drive system to the piston, creating the pumping action that moves material through the sprayer. It includes all necessary seals and components for a complete replacement.

A worn or damaged pusher stem can lead to inefficient pumping, pressure loss, material leakage, and inconsistent spray patterns. Replacing the complete assembly ensures proper fit, reliable sealing, and restored performance in demanding spraying applications.

Service Note: When replacing the pusher stem assembly, inspect the cylinder bore for scoring or wear. A damaged cylinder can quickly destroy new seals and should be addressed during repair.

What it does and when to replace it

What the pusher stem assembly does

Frequently Asked Questions

The 2423817A Pusher Stem Assembly includes the complete pusher stem shaft, all necessary seals and packings, retaining rings, and wear washers. Some assemblies may include installation lubricant. This complete kit provides everything needed to replace the pusher stem component in the fluid section of Impact X440 and X540i sprayers.

Signs that your pusher stem needs replacement include: visible scoring or wear on the stem surface, material leaking past the stem seals, a bent or damaged stem causing binding, reduced spray pressure, or inefficient pumping performance. Regular inspection during maintenance will help identify wear before it causes operational issues.

Yes, the 2423817A pusher stem assembly is designed to fit both Impact X440 and X540i models. These X-series sprayers share a common fluid section design, allowing the same pusher stem assembly to be used across both models. Always verify compatibility with your specific model and serial number.

Installation requires disassembly of the fluid section and mechanical aptitude. The process involves removing the old stem assembly, cleaning and inspecting the cylinder bore, carefully installing new seals, and reassembling with proper torque. Special tools may be required. If you're not experienced with sprayer repair, consider having the work done by a qualified service technician. Always consult your Impact X440 or X540i service manual for specific procedures.
