Impact X parts fall into seven groups: suction set, filter, fluid section, drive, main assembly or frame, cart, and accessories. The parts that touch paint (inlet screen, 60 mesh filter, valve balls, seats, packings, piston rod) are the ones that wear and get replaced. Frame, cart and drive parts are replaced when something breaks or is damaged.
The Impact X 410, Impact X 440 and Impact X 540I are built on the same idea, and the site gives each of them seven diagram pages. Once you know what each page is for, a repair gets much quicker: you stop scrolling for a part and open the one page where it lives. This guide goes through the machine in the order the paint travels, then covers the parts that only get replaced when something is damaged.
The Seven Diagram Pages on Each Model
Each of the three models has the same set of seven pages, with one difference: the 410 and 440 have a single cart page and a Drive Assembly page, while the 540I has separate High Cart and Low Cart pages and no drive page on the site.

| Main Assembly | Frame, shrouds, legs and the paint-side bits that ride on them | Inlet screen 710-046, legs, drip cup, foot rubber, pail hook |
| Cart or High/Low Cart | Wheels and handle | Wheel 0278373, handle kit, cart weldment 2426732A |
| Accessories | Hoses, guns, valve kits, lubricant | Inlet valve kit 805-846, Liquid Shield 314-482, Piston Lube 314-480 |
Part numbers are shown as they appear on the site's diagram pages. Callout numbers change from page to page, so always read the callout on the page you are on.
Suction Set: Where Paint Enters
The suction side is where a lot of priming trouble starts, and its parts are small. The suction set page for the Impact X 440 lists the siphon tube assembly, the return tube, the inlet screen filter, two O-rings, a clip and a retaining clip. The 410 and 540I pages carry the same core parts; the 410 page lists a return hose assembly where the 440 and 540I list a return tube.
Two things to know. The 700-805 inlet screen filter is the first thing paint meets, so a clogged one starves the pump. Titan's Impact manuals list a clogged inlet screen or siphon tube, and an air leak at the siphon tube or suction set, among the reasons a sprayer will not prime. The page also lists O-ring 9871105 and retaining clip 9822526, which hold the siphon tube tight on the pump; tighten or replace them if you find an air leak.
Filter Assembly: The Vertical Housing
Impact X sprayers use a vertical filter housing, which Titan says cleans up to three times faster and with as little as one third of the water. On the diagram it is a short stack: filter cap 2424931A, an O-ring, a core where the page lists one, the 60 mesh filter 2424933, and the filter bowl 2424886A. The 440 and 540I pages also list a by-pass valve assembly, 2440405.
The same page carries the transducer 2427607A. Titan says the Logix Adaptive Pressure Control on the X 410, X 440 and X 540I senses tip size and adjusts pump speed and power, so keep the transducer in mind if a sprayer will not hold the pressure you set and the filter and tip are fine.
Fluid Section: The Parts That Wear
This is the pump end, and it is where most replacement orders come from. The three Impact X fluid-section pages list the same core set: outlet valve ball 50164, inlet valve ball 762-145, foot valve seat 762-137, outlet valve seat 704-558, inlet valve cage 704-703, outlet valve retainer 13481, upper piston guide 700-587 and the seat O-ring 762-058. The piston rod and piston assembly (2420579A and 2420580A) and the retainer 2420537 are also listed against these models.
- Balls and seats open and close each stroke. When they wear, you get pulsing, trouble priming, or a sprayer that will not hold pressure. The site sells them as inlet valve kit 805-846 and outlet valve kit 805-845.
- Packings seal the piston rod. The Impact X 440 and 540I fluid-section pages list repacking kit 704-586B.
- The piston rod needs a smooth surface. A scored rod ruins new packings, so inspect it whenever the pump is open.
- PermaLife Cylinder: Titan lists it on the X 410 and says it never wears and never needs replacing. That covers the cylinder only; balls, seats, packings and the rod still wear.
Titan also says the Impact X has a MaxFX No Tools Fluid Section that changes in minutes with just your hands. That is why you will see complete fluid section assemblies on the site, such as 2453422 on the 410 pages and 2456446 for the 540I. A swap of the whole section is a real option when the pump end is worn throughout.
Drive and Controls
The Impact X 440 drive page holds the main housing assembly, connecting rod, the crankshaft/gear assembly 704-173A, the second stage gear 704-176, a thrust washer, the motor fan assembly, the potentiometer 2423449, the control knob 805-354 and the 15A fuse 800-929. Titan lists a DuraLife HE brushless motor on all three Impact X models.
Frame, Cart and Accessories
The main assembly pages hold the pieces that get knocked about on a job: legs, shrouds, the drip cup 2440144 on the 440 and 540I, foot rubber 805-342, and the pail hook assembly 2426230A on the 410 and 540I. Cart pages carry the wheel 0278373, hub caps and handle kits. The 540I low cart page lists its own handle weldment, sleeve handle and snap button, so check the High or Low Cart page that matches your sprayer.
The accessories pages are where hoses, guns, gun filters, Piston Lube and Liquid Shield sit. They are worth opening even when your problem is elsewhere, since a clean gun filter is one of the easiest things to try first for a poor pattern.
