The 6900 Plus DI main assembly diagram lists the motor pump assembly (451-135A), filter assembly (0290453A), bleed valve assembly (944-030A), bleed hose (0528034), V-belt (449-125), belt guard assembly (0290629A), shroud, power kits and the cart assembly. Order the belt, guard and engine kit from the DI diagrams for your sprayer.
What is on the main assembly diagram
The 6900 Plus DI main assembly page is the overview diagram for the sprayer. It does not list the pump internals. It shows the big assemblies that bolt together and the hardware that holds them, and several of those assemblies have their own diagram pages with the detail. A PowrTwin 6900 Plus DI is a hydraulic-drive piston sprayer: an engine or electric motor drives a hydraulic motor, which strokes the piston in the fluid section. The main assembly is where those pieces meet.
Before you buy anything from it, confirm you are on a DI model. Titan describes DI models by their submersed foot valve and does not define the letters, so the safest check is the model name on your sprayer's tag. Standard 6900 Plus parts are on different diagrams.
6900 Plus DI main assembly: the numbered assemblies
| Callout | Part | Number |
|---|---|---|
| 1 | Motor pump assembly | 451-135A |
| 3 | Bleed valve assembly | 944-030A |
| 4 | Filter assembly, packaged | 0290453A |
| 5 | Bleed hose | 0528034 |
| 7 | Belt guard assembly | 0290629A |
| 10 | Pump shroud | 0290490 |
| 19 | V-belt, listed as A-40 | 449-125 |
| 20 | Cart assembly | 0290537A |
The page also lists a swivel fitting assembly (703-137A), a bypass tube clip (0537537), a bracket (0528235) and the screws, bolts and lock washers that hold it together.
The motor pump assembly is sold as one assembly. We do not list what is inside it here, so if you are working on the hydraulic side, call our parts team to confirm what 451-135A includes. The seals and spool parts of the hydraulic motor have their own page, 6900 Plus DI Hydraulic motor.
The filter and bleed valve assemblies
Two of the numbered items on the main page are complete assemblies that you will usually service by their parts rather than replace whole. The filter assembly 0290453A is the high-pressure filter, and the detail is on the high pressure filter page: the manifold filter element in 0, 5, 50 or 100 mesh (930-004 to 930-007 by coating), the tungsten carbide seat 180-909, the spring 930-020 and the filter service kit 930-050. Titan's manual says the filter works from the inside out, and that you replace the element if its ball shows pressure cuts and the carbide seat if it is nicked.
The bleed valve is the valve you open as the last step of the pressure relief procedure. Its parts are on the 6900 Plus DI bleed valve assembly page. The main diagram lists a second bleed valve assembly, 448-615A, at callout 25, and the site has a separate heavy materials bleed valve page. Look at the valve on your sprayer and match it to one of the two diagrams before ordering a stem, seat or seal.
Drive parts: belt, guard and shroud
The main page lists the V-belt as 449-125, shown on the diagram as an A-40 belt, and the guard that covers it as belt guard assembly 0290629A. Take the belt number from the diagram for your own sprayer rather than from memory or a belt in the shop, because the PowrTwin diagrams list different belts for different models. Titan's Plus manual describes changing a V-belt after pressure relief by opening the belt guard and lifting the front of the engine or motor to release belt tension, so look at your manual before you start.
The belt guard assembly page breaks the guard into its pieces, and it is the page to open if only part of the guard is damaged. It lists the belt guard weldment (0290628A), the front belt guard (0290627A), the mounting bracket weldment (0290626A), a hinge (0290794) and the small fasteners. If the rest of the guard is sound, you can order just the hinge or the front guard instead of the whole assembly.
Power kits: engine and electric
A PowrTwin can run on gas or electric power, and the two are changed with a Convertokit. On this model the main assembly lists the packaged Convertokit 0290614A, a DC electric 230V Convertokit 0290321A and a DC electric 400V Convertokit 0528612A. It also lists a Convertokit for the PT6900, 8900 and 12000 (2464186A). Pick by the voltage and power type your sprayer has, and call us if the listing names do not settle it.
If your sprayer is the gas version and you need engine parts, open the 6900 Plus DI gas convertokit page. It lists the Honda gas engine (980-331A), the engine mounting plate (0290484), the pulley (449-984) and the key and fasteners. Do not rely on the horsepower in a part title, because the diagram titles and Titan's manual do not agree on horsepower across the family. Match the engine by the number on the diagram.
Cart
The cart is listed here as one assembly, 0290537A. When a wheel, handle grip or pin is the problem, use the 6900 Plus DI cart assembly page, which lists items such as the wheel (670-109), the grip handle (451-074) and the roll pin (590-508) individually.
Finding the right part
Confirm the model
Check the tag for 6900 Plus DI, and whether it is gas or electric. The gas and electric versions use different power kits.
Open the matching page
Use the main assembly page for the big assemblies, and the belt guard, gas convertokit, filter, bleed valve, hydraulic motor or cart page for detail.
Match the callout number
Find the number on the picture, read the part number beside it and add that part. Buy the belt by the number listed on the diagram, not by size from another sprayer.
Call if two numbers look right
Phone (713) 931-0006 with the model and serial number. Manuals for the procedures are on our manuals page.

The Short Version
The main assembly page is the map. Use it to identify the big assembly or the belt, then drop to the belt guard, gas convertokit, filter, bleed valve or cart page for the small parts. Take the belt and the engine kit from the diagram for your exact sprayer.
