The PowrLiner 4955, 6955 and 8955 share 3300 psi, a 12-gallon hopper and hydraulic drive. They step up in engine and flow: a Honda GX120 and 1.25 gpm on the 4955, a GX160 on the 6955 and a GX200 and 2.50 gpm on the 8955. The fluid sections, hydraulic motors and engines are listed under different part numbers, so order from the diagram for your model.
What the three have in common
The three hydraulic PowrLiners are built on the same idea and the same frame. Titan lists these features for all of them:
- A maximum of 3300 psi, with the pressure control adjustable from 400 to 3300 psi
- A 12-gallon paint hopper and a 1/4 in. x 50 ft hose
- A two-gun configuration with S-3 guns
- SmartArm gun mount, DeadLock handlebars adjustable three ways and a PowrCenter dashboard with a pressure gauge
- Hydraulic drive, which Titan describes as smooth and slow-stroking
The manual's maintenance rules are the same across the three too: Titan Coolflo is the only hydraulic fluid allowed, the level is checked daily against the Full mark on the dipstick, and the packing oil cup is filled half full with Piston Lube. Because the care routine is shared, the choice between them comes down to flow, engine and parts.
Where they differ
PowrLiner 4955, 6955 and 8955 side by side
| 4955 | 6955 | 8955 | |
|---|---|---|---|
| Titan item | 0290052H | 0290053H | 0290054H |
| Max delivery | 1.25 gpm | Confirm in your manual | 2.50 gpm |
| Engine | Honda GX120, pull start | Honda GX160, electric start | Honda GX200, electric start |
| Weight | 324 lbs | 334 lbs | 339 lbs |
| Max tip, gas | Confirm in your manual | Confirm in your manual | 0.054 in. (1 gun), 0.038 in. (2 guns) |
Sources disagree on the 6955 delivery figure and on the 4955 and 6955 tip sizes, so those cells are left for the manual. The 1.25 gpm figure is for the current Honda-engine 4955; older units with a different engine are listed with other figures.
So the step up is flow and engine. The 8955 has twice the 4955's rated delivery and the largest engine, and it is also the heaviest by a small margin. If your jobs never need more than the 4955 delivers, the extra engine is not buying you anything; if they do, the next step is a model with its own diagrams, not a part swap.
Fluid sections are not interchangeable
This is where an order for the wrong model usually goes wrong. The three fluid section diagrams are different pages with different numbers:
Fluid section parts by model, as listed on each diagram
| Part | 4955 | 6955 | 8955 |
|---|---|---|---|
| Repacking set or kit | 106-002A | 138-153A | 138-153A |
| Rod | 107-029 displacement rod | 143-127A piston rod | 144-117 displacement rod |
| Pump cylinder | 107-946 | 143-822 | 144-832 |
| Major service kit | 107-501 | 143-500 | 144-500 |
| Other kit on the page | 107-051 service kit | 143-050 pump repair kit | 144-050 minor service kit |
Open the fluid section page for your model and take the numbers from there.
The 4955 page has almost nothing in common with the other two: a retaining ring and one or two small items. The 6955 and 8955 pages are closer. They list the same repacking kit, packing springs and most valve parts, and differ in the rod, the cylinder and the service kits. Because the rod and cylinder differ, a repacking kit number being shared does not make the rod or kit interchangeable.
Other assemblies: what is shared and what is not
Comparing the diagram pages part by part gives a clearer picture of where you can relax and where you cannot:
How the other diagram pages compare
| Assembly | How the three compare |
|---|---|
| Hydraulic System | Essentially the same list on all three: 449-718A tank, 451-220 filter and 449-626 dipstick appear on each |
| Bleed Valve, Gun Holder, Lift/Tilt | The same part numbers on all three pages, apart from one washer on the 6955 lift/tilt page |
| High Pressure Filter | The 6955 and 8955 pages add the 930-005 and 930-007 manifold filters to the list the 4955 page has |
| Hydraulic Motor | The 4955 and 6955 pages share most parts; the 8955 page lists its own hydraulic cylinder, valve rod assembly, long piston rod and motor pump block. The 235-050 service motor kit is on all three pages |
| Main Assembly | Each lists its own motor/pump assembly: 235-117A (4955), 235-118A (6955), 236-154A (8955) |
That is a listing comparison, not a statement that parts on different pages are interchangeable. It does show that the oil side, with the tank, filter and dipstick, is routine across the family, while the fluid section and motor are the model-specific parts. The 6955 hydraulic motor page is a useful one to compare with the 4955 and 8955 pages if you are checking which motor parts apply.
Engines and convertokits by model
Each model has its own gas convertokit page, and each lists a different Honda engine number:
- 4955: gas convertokit, with the 980-332A Honda gas engine.
- 6955: gas convertokit, with the 0537546A Honda engine.
- 8955: gas convertokit, with the 0537547A Honda engine. The 8955 main assembly page also lists 0537265A, a 5.5 Hp Honda electric start convertokit.
The two engine listings, 0537546A and 0537547A, each name the 4955, 6955 and 8955 in their fitment notes, which is exactly the situation where the diagram page is more useful than the note: the 6955 page shows 0537546A, and the 8955 page shows 0537547A. The site also has a DC-electric convertokit page for the 4955. Call us for fitment if you want to move a machine between gas and electric.
Which one suits which volume
Titan's specs support one conclusion and not more. Delivery runs from 1.25 gpm on the 4955 to 2.50 gpm on the 8955, and Titan's 8955 tip limits show how that flow is divided: a larger tip on one gun than on two. We do not give job sizes, paint volumes or coating suitability by model, because Titan does not publish them in the sources we use. The 4955 is positioned for medium to large striping projects. Choose the 6955 or 8955 when your work needs the higher flow and the larger engine, and check tip limits for your configuration in the manual before you order tips.
Find your model's parts
Confirm which model you have
Read the model name from the machine's label or manual. The three look similar, and the difference is in the part numbers.
Start with the fluid section page
Open the page for your model and take the repacking, rod, cylinder and kit numbers from there.
Check motor, hydraulic system and filter pages
Each model has its own pages for the hydraulic system, the hydraulic motor and the high pressure filter.
Call if a fitment note and a diagram disagree

The three machines and the model-specific parts that matter most when you compare them:
The Short Version
The three share their features and their oil side. They differ in flow (1.25 gpm to 2.50 gpm), engine (GX120, GX160, GX200) and, above all, in the fluid section, hydraulic motor and engine parts. Order each of those from the page for your own model.
