The site lists an inlet valve kit (805-846), an outlet valve kit (805-845) and a repacking kit (704-586B) for the Impact X pump end, plus a gun repair kit and several hardware and frame kits. Pulsing, priming trouble and pressure loss usually point to the valve kits or the repacking kit. Check the product page for each kit's contents and the diagram for your model.
A repair kit saves you hunting through a diagram for six small parts, but only if it is the right kit for the fault. On an Impact X the kits listed on the site fall into four groups: pump-end kits, a gun kit, frame and hardware kits, and the filter and consumable items that people often add to the same order. This guide sorts them by the symptom they answer. It does not list what is inside each kit, because the diagram pages list a kit as one line and the contents are on each kit's product page.
Start with the symptom, not the kit
Titan's Impact manuals put the cheap checks first: the PRIME/SPRAY valve in the right position, a clogged inlet screen or pump filter, an air leak at the siphon tube or suction set, and a worn tip. Kits come after those, because a kit will not fix a blocked filter. If the sprayer still will not prime or hold pressure once those are clear, the manuals point at the fluid section: worn packings, worn valve balls or worn seats.
Which kit group fits which symptom
| What you see | First checks (no kit) | Kit group to look at |
|---|---|---|
| Will not prime | PRIME/SPRAY valve, stuck inlet valve, air leak at the siphon tube, clogged inlet screen or filter | Inlet valve kit |
| Will not build or hold pressure | Tip wear, clogged filters, air leaks | Valve kits, then repacking kit |
| Pulsing at the gun | Filters and tip | Repacking kit (Titan's manuals name worn upper packings) |
| Paint leaking at the top of the fluid section | Tighten external fittings | Repacking kit, or valve kits if seats and balls are worn |
| Gun leaks or trigger feels wrong | Tip seal, gun filter | Gun repair kit |
Symptom logic follows the Titan Impact manuals (640, 1040, 410 and Impact X 410 excerpts). Always follow the pressure relief procedure in your own manual before opening anything.
Pump-end kits: valves and repacking
Three pump-end kits are listed on the Impact X diagram pages. The catalog fitment for the 805-846 inlet valve kit and the 805-845 outlet valve kit lists the Impact X 410, X 440 and X 540I. The 704-586B repacking kit appears on the X 440 and X 540I fluid section pages. The X 410 fluid section page does not list it, so for a 410 confirm the repacking part numbers on its own page or call us first.
Pump-end kits and the parts around them
One point worth knowing: Titan says the PermaLife cylinder never wears and never needs replacing, and the X 410 lists it. So a worn pump on an Impact X is a packing, ball, seat or rod question, not a cylinder question. Titan also says the Impact X fluid section is tool-free (MaxFX No Tools Fluid Section). If the fluid section itself is damaged rather than just worn, whole fluid section assemblies are listed, for example 2453422 on the X 410 drive page and 2440559 on the X 440 drive page.
How to tell valve trouble from packing trouble
- Pulsing or surge at the gun with clean filters and a good tip points toward the packings.
- A sprayer that will not prime, with the PRIME/SPRAY valve set correctly and no air leak, points toward the inlet valve. Titan's Impact X 410 manual excerpt lists a stuck inlet valve as a cause.
- Pressure that will not hold after the tip, filters and fittings are ruled out points inside the fluid section: balls, seats or packings.
- If you are not sure which, Titan's manuals send you to the fluid section: clean the valves and service it, rather than guessing at one part.
The gun kit
The X 410 and X 440 ship with an RX-80 gun, according to Titan. The site lists a 0538215 RX-80 Gun Repair Kit on the Impact X 120 spray gun page, next to its single parts (tip seal, swivel, seal assembly, retractor parts and the trigger and lock assembly). A leaking or sticky gun is cheaper to fix than a pump, so rule the gun out before you open the fluid section. Check the kit's product page for fit with your gun, or call us.
Frame and hardware kits
These are not wear items, but they appear on the same pages and are easy to confuse with pump kits. The diagrams list a 2440399 drive assembly hardware kit on the X 410 drive page, a 2440442 main hardware kit, a 2440400 handle kit, a 2440401 skid leg kit and a 2440403 cart frame kit. Which one you need depends on whether your sprayer is a skid, high rider or low rider build, so open the cart or main assembly page for your model first.

The short version
Rule out the cheap faults first: valve position, filters, siphon tube and tip. Then match the symptom to a group: priming trouble to the inlet valve kit 805-846, pressure that will not hold to the outlet valve kit 805-845, surge and leaks at the top of the pump to the repacking kit 704-586B. Open the product page to confirm what is inside a kit, and call (713) 931-0006 if your model or fit is unclear.
