A Hydra M2000 part is found by assembly. The fluid pump is the 315-555, the hydraulic motor diagram is the 441-576, and the bleed valve, outlet and accessories each have their own page. Open the diagram for the assembly that is failing, match the numbered callout to your sprayer, and order the part number shown. If a callout is unclear, call (713) 931-0006 with your model and serial number.

Start with the model number on your sprayer
Titan's Hydra M manual lists the M2000 under two model numbers: 433-860 and 433-861, the second being the 55-gallon version. Write down whichever appears on your plate, along with the serial number, before you open any catalog page. It is the one piece of information that settles most fitment questions.
The M2000 is the high-volume member of the older Hydra M line. The manual gives it a pressure range of 500 to 2000 psi and a maximum delivery of 6.0 gpm, with a largest single-gun tip of 0.075" and 0.053" with two guns. It is a gas-engine, hydraulic-drive airless sprayer: a Honda engine drives a hydraulic pump, and a hydraulic motor strokes the piston-type fluid pump.
That layout is also how the parts are organized. Everything in the sprayer belongs to one of four groups, and each group has its own diagram page on the site.
The four assemblies, and the diagram page for each
Where to look on AllTitanParts.com
| Assembly | What it does | Diagram page |
|---|---|---|
| Fluid pump 315-555 | The piston pump that moves paint: packings, balls, foot valve, cylinder | Hydra M2000 315-555 Fluid Pump Assembly |
| Hydraulic motor 441-576 | Strokes the pump; spool valve, trip spring, seals and O-rings | Hydra M2000 and Hydra M4000 441-576 Hydraulic Motor |
| Bleed valve and outlet | Relieves pressure; connects the hose, bleed line and swivel adapters | Bleed Valve, Bleed Line and Outlet Assemblies pages |
| Accessories and filters | Filter elements, siphon hoses, manifold, Coolflo, Piston Lube, service kits | Accessories |
The Major Components page for the M2000 shows how these assemblies fit together and is a good place to start if you are not sure which one has the fault.
315-555 pump: packings, foot valve, balls, cylinder.
441-576 motor: spool valve, trip spring, O-rings.
The whole sprayer on one page: motor pump, pump, hoses, bleed valve.

How to read a diagram page and get the number right
Open the assembly that matches the symptom
Paint leaking at the wet cup or a pump that will not hold pressure points to the fluid pump page. A sluggish or stalling pump with the engine running points to the motor page. Paint or pressure escaping near the outlet points to the bleed valve and outlet pages.
Find the numbered callout
Each page shows the assembly with numbers on the drawing. Match the number to the list under it. For example, on the 315-555 pump page the upper packing set is callout 3 and the foot valve is callout 18.
Copy the part number exactly
Some numbers carry a letter suffix, such as 314-030A. The letter is part of the number, so enter it as shown.
Watch for look-alike assemblies
The M2000 and M4000 share the 441-576 motor, but their fluid pumps are different assemblies (315-555 and 245-555). Always take pump parts from the page for your own pump.
Call if the callout does not settle it
Have the model and serial number ready and phone (713) 931-0006. That is quicker than ordering a near match.
What wears first in the fluid pump
On a piston pump the parts that rub and seal are the ones that fail. The 315-555 page lists the 314-030A Upper Packing Set (callout 3), the 317-925 Foot Valve (callout 18) and the 315-700 Stainless Ball (callout 16), along with the pump block, cylinder and a PTFE O-ring.
Titan's manuals tie these to symptoms. A pump that delivers only on the upstroke has a lower foot valve ball that is not seating, from trash or wear. Delivering only on the downstroke means the upper ball is not seating, and the manual says to clean and inspect the upper seat and replace the packing if it is worn. A pump that chatters may have an upper packing swollen by solvent, which means replacing the packing set. Follow the manual's own steps for your model.
The site also lists the 315-500 Major Pump Service Kit and the 315-050 Pump Service Minor Kit under Accessories. Catalog data lists them for Hydra M and Hydra Pro series pumps, so confirm which kit matches the 315-555 on your unit against the diagram or with our parts team before buying.
Hydraulic motor, bleed valve and outlet parts
The motor diagram holds the small hydraulic parts: the 441-908 Spool Valve with Sleeve, the 441-005 Spring Trip, the 441-979 Trip Spring Retainer, the 441-149 Backup Ring and a set of O-rings. Titan's Hydra M manual says to inspect the spool valve for scratches and rough movement when the motor misbehaves. The hydraulic pump itself is not field-serviceable according to the manual, so a fault there is a call to Titan, not a parts order.
The M2000 has two bleed valve pages, one for a 1/8" NPT valve and one for a 1/2" NPT valve, so check which one your sprayer carries before ordering seats, balls or O-rings. The outlet assembly page shows the swivel adapters, pipe cross and tee that connect the 945-600A Bleed Valve to the hose, and the bleed line with valve page covers the 944-028A Bleed Valve Assembly and its line.
Daily-use items to keep on hand
- 430-361 Coolflo hydraulic fluid. Titan calls Coolflo mandatory and says not to use any other hydraulic fluid. The manual says to check it daily on the dipstick and to change it with the external filter every six months.
- Filter elements, such as the 920-004 50-mesh element, and the 920-050 Filter Service Kit. A loaded filter causes pulsing and low pressure before it causes a breakdown.
- 314-480 Piston Lube is listed for the upper packing in Titan's manuals, but the Hydra M manual also mentions another wet-cup fluid, so read what it says for your model before filling the cup.
- The 103-818A Siphon Hose Assy on the Major Components page, if you pull paint from a pail.
These parts are listed on the M2000 diagrams. Check each against your callout before adding it to the cart.
Why genuine matters on a hydraulic-drive sprayer
AllTitanParts.com is an Authorized Titan Dealer and supplies genuine OEM manufacturer parts. Because every part on the site is attached to a diagram and callout, you can verify what you are buying against the drawing instead of judging by a logo or packaging. Part numbers and diagrams are for identification and fitment; the manual stays the authority for procedures and safety.
The short version
Get the model number (433-860 or 433-861), pick the assembly that matches the symptom, read the callout and copy the part number exactly, including any letter. Start with the free checks. If it is still unclear, call (713) 931-0006 with the model and serial number.
