On the PowrBeast 4700/4700T Main Assembly II diagram, the gas power end is the 730-163 Honda engine. The electric power end is the 0537560A 120V motor assembly, 0537495A transformer and 0537249 motor tray assembly. The solenoid, hydraulic filter and fluid section sit on the hydraulic side, shared by both versions. Confirm your power type before ordering.
One diagram page, two power ends
A PowrBeast 4700 is built the same way whether it runs on gas or electricity: something turns a hydraulic pump, and the hydraulic side drives the fluid section. Only the first part of that chain changes. The site does not split the 4700 into a gas page and an electric page. The 4700/4700T Main Assembly II page lists the gas engine and the electric motor parts together, so you have to know your power type and pick the right group from the list.
That is easy to get wrong in a hurry. Someone looking for a motor sees a motor, and someone looking for a pulley sees two. The sections below sort the page into what belongs where, going by the part names on the diagram.
Gas side
The gas power end is the 730-163 Engine, Gas, Honda, which is callout 21 on the Main Assembly II page. Dealer listings for the gas 4700 give the engine as a Honda GX160, and Titan says its gas PowrBeasts have a Honda engine with a low-oil alert system. Engine oil, spark plug and fuel details are in the Honda manual and Titan's manual, not here, and gas engines should only be run outdoors or somewhere well ventilated.
The same page lists two pulleys, 0528108 (callout 22) and 0290407 (callout 22A), and a 490-117 bushing at callout 23. The page does not say which of these goes with which power type, so if you need a pulley, check with us on (713) 931-0006 and give your model and serial number.
Electric side
The electric version replaces the engine with an electric motor assembly and the parts that feed it. Three part numbers on the same Main Assembly II page cover that:
Electric 4700 power-end parts
Titan's spec block for the electric 4700 gives a 2.0 hp electric motor and a 120V supply. A hydraulic sprayer at this class needs a suitable power supply and extension cord, so check your cord against your manual before blaming the motor for a problem that comes from the supply.
Shared hydraulic and fluid parts
Past the power end, the diagram pages are shared by both versions. These parts appear on those shared 4700/4700T pages:
- 0537207A solenoid assembly, listed on the Solenoid Assembly page and again on the hydraulic system and Main Assembly II pages.
- 451-220 hydraulic filter, 537351 hydraulic pump and the 0537225A tank assembly, all on the Hydraulic System page.
- 0537252A motor / pump assembly, on the Main Assembly I page.
- 0537255 fluid section assembly. Titan lists 537255 for the PowrBeast 4700, gas or electric, so the fluid section is not tied to the power type.
Main Assembly I also lists the control items: the 0537305B pressure control knob, the 0537227A PCB board assembly, the 522622 black switch and the 2301766 control lamp, plus the 0537468A top shroud and 0537359 motor cover. The page does not mark any of them as gas-only or electric-only, so if you are ordering a control part, tell us your power type when you call and we will confirm it fits.
That last point is useful. If your problem is pressure, packings or valves, the power type does not matter, because the fluid section diagram is the same for both.
Specs that differ between the two
PowrBeast 4700 gas and electric, from Titan and dealer listings
| 4700 gas | 4700 electric | |
|---|---|---|
| Max delivery | 1.6 gpm | 1.1 gpm |
| Power | Honda GX160 | 2.0 hp electric motor, 120V |
| Max tip, 1 gun | 0.041 in. | 0.033 in. |
| Max tip, 2 guns | 0.029 in. | 0.023 in. |
| Max tip, 3 guns | 0.021 in. | 0.019 in. |
| Max tip, 4 guns | 0.019 in. | not listed |
Max operating pressure is 3300 psi on every PowrBeast. Tip figures are as listed by Titan and dealers; we do not state a gun count for the 4700. For the 4700T, sources disagree on gas or electric, so check the label on your machine.
The tip limits are worth knowing before you buy a tip or a hose set: stay at or under the listed maximum for your power type and the number of guns you run, and check your manual for the rest.
Confirm before ordering
Identify your power type
A Honda engine means gas. A power cord and motor means electric. If your machine is a 4700T, check the label on the unit.
Open the right page
Use the Main Assembly II page for engine, motor, transformer and tray; use the shared hydraulic and fluid section pages for everything else.
Match the callout
Add the part from the numbered callout, then check the part number against your old part.
Call if the page does not settle it
Phone (713) 931-0006 with the model, power type and serial number. Manuals are on our manuals page.

The Short Version
Only the power end differs between a gas and an electric 4700: the 730-163 Honda engine on one side, the 0537560A motor, 0537495A transformer and 0537249 tray on the other. The hydraulic side and the fluid section are shared. Know your power type, then pick from the page.
