The Plus diagrams list different belts: 449-125 (A-40) on the 6900 Plus and 6900 Plus DI, 0290536 (A-41) on the 8900 Plus and 0290510 (AX44) on the 12000 Plus, with 449-181 (A-38, listed as 120V) also on those pages. The belt guard assembly is 0290629A. Pick the belt from your own model's diagram.
Why the belt matters
A PowrTwin is a hydraulic-drive sprayer. The gas engine, or the electric motor on an electric model, turns a V-belt that drives the hydraulic pump, and the hydraulic motor strokes the piston in the fluid section. The belt runs under a belt guard. When it slips or breaks the pump stops, so it is a part to keep an eye on and to buy by the right number.
Titan's manual says belt tension is released by lifting the front of the engine or motor after the belt guard is opened. That is the only belt procedure detail this page gives, because it comes from the manual and your model's manual is the right place for the rest.
Belts listed on each diagram
V-belts on the PowrTwin Plus main assembly diagrams
| Model | Belts listed | Diagram page |
|---|---|---|
| 6900 Plus | 449-125 (A-40) and 449-181 (A-38, 120V) | 6900 Plus main assembly |
| 8900 Plus | 0290536 (A-41) and 449-181 (A-38, 120V) | 8900 Plus main assembly |
| 12000 Plus | 0290510 (AX44) and 449-181 (A-38, 120V) | 12000 Plus main assembly |
| 6900 Plus DI | 449-125 (A-40) | 6900 Plus DI main assembly |
Belt sizes are as the site's diagrams name them. A belt number from one model's diagram may not fit another, so use your own model's page.
Two things are worth noticing. First, the three Plus models do not share a belt: the 8900 Plus and the 12000 Plus list different belts, and the same A-38 number appears on all three as a 120V item. Second, the 6900 Plus DI page lists only 449-125. If the tag on your sprayer says DI, use the DI pages, not the 6900 Plus ones.
Belt guard parts
The complete guard is listed as 0290629A on the main assembly pages. When only part of it is damaged, the belt guard pages list the pieces separately: the 6900 Plus, 8900 Plus and 12000 Plus pages show the same pieces, and the 6900 Plus DI page matches them.
- 0290628A belt guard weldment, packaged.
- 0290627A front belt guard.
- 0290626A mounting bracket weldment.
- 0290794 hinge, and 0528345 guard bolt.
- Small hardware: screws, a nut, a seal washer and a retaining ring, listed by number on the page.
Pulleys
The engine pulley is on the gas Convertokit page, not the main page, and it differs by model. The 6900 Plus and 6900 Plus DI list 449-984, the 8900 Plus lists 0290797 and the 12000 Plus lists 0290409. If you change a pulley, change it for the one on your model's page and ask us about the belt to go with it.
Ordering the right belt
Confirm the model
Check the tag for 6900, 8900 or 12000, and whether it is a Plus or DI.
Open that model's main assembly page
Find the belt callout and read the number beside it.
Do not trust a belt you already have
A belt that seemed to fit a different sprayer is not proof. Use the diagram number.
Call if the diagram lists two
Phone (713) 931-0006 with the model and serial number, and say whether the sprayer is gas or electric. Manuals are on our manuals page.
