ROP Shop Pump Outlet Comparison
Outlet orientation
The ROP Shop OEM AR 2600 PSI 2.2 GPM 7/8" Shaft Power Pressure Washer Pump features an EZ Front-Facing or Right-Handed outlet design. This means the water exits toward the front of the unit. In contrast, the OEM AR 2600 psi Power Pressure Washer Water Pump is an EZ-SX Rear-Facing or Left-Handed version. Its outlet is positioned at the back. This distinction matters for your hose routing and overall machine layout. You must match the outlet direction to your specific engine configuration. Choosing the wrong orientation can complicate installation or restrict hose movement. Both pumps share identical internal specifications, but the physical exit point differs significantly.
Compatibility model
Product A is explicitly compatible with Troy-Bilt models 020415 and 020415-0. Product B fits Troy-Bilt models 020344 and 020344-0. While both are replacement pumps for Troy-Bilt equipment, they serve different original equipment manufacturer part numbers. You need to verify your specific unit's model and serial number before purchasing. The data does not indicate that these pumps are interchangeable between these distinct model lines. Using the wrong pump for your specific Troy-Bilt machine could lead to fitment issues. Always cross-reference your existing OEM part number with the listed compatible models to ensure a proper fit for your pressure washer.
Physical dimensions
Both pumps share the same length of 13 inches and height of 8 inches. They also weigh the same at 5 pounds. However, Product A has a width of 8.5 inches, while Product B is slightly narrower at 8 inches. This half-inch difference in width might affect how the pump fits within tight engine compartments or specific mounting brackets. For most standard installations, this variance is negligible. You should measure your available space if you have a very compact setup. Otherwise, the footprint is nearly identical, ensuring both units occupy similar space on your pressure washer chassis during operation or storage.
Included components
Both units include a vertical pressure washer pump with a thermal release valve and chemical injector already installed. Neither product includes the engine shaft key or mounting bolts. Product A is described as coming as shown in the first image without these hardware items. Product B lists the specific part number SRMW22G26-EZ-SX but also excludes the shaft key and bolts. You will need to source the necessary hardware separately for installation. Since both omit these critical mounting components, you face the same preparation requirements regardless of which pump you choose. Ensure you have the correct bolts and key ready before beginning the swap.
Performance specs
Both pumps deliver identical performance metrics. They both generate a maximum pressure of 2600 PSI and a maximum flow rate of 2.2 GPM. The shaft size is 7/8 inch for both. The bolt pattern measures 7 11/16 inches by 6 3/16 inches by 6 7/16 inches from center to center. Oil capacity is 2.29 oz for each. Inlet type is 3/4 inch GHA, and outlet type is 22mm by 14mm. Maximum fluid temperature is 140 degrees Fahrenheit for both. There is no performance difference between them. You get the same cleaning power and water volume from either unit, making the choice purely about physical fitment and orientation.

Frequently asked questions
Which pump fits a Troy-Bilt machine with a front-facing outlet?
The ROP Shop 2600 PSI 7/8-Inch Vertical Pump (ASIN B07CN3QVDY) is the correct choice. It features an EZ Front-Facing or Right-Handed outlet design. This orientation allows water to exit toward the front of the unit. It directly matches Troy-Bilt models 020415 and 020415-0. You should verify your shaft size is 7/8-inch before purchasing.
Does the AR 2600 PSI pump have rear-facing outlets?
Yes, the ROP Shop AR 2600 PSI Replacement Pump (ASIN B07D3D99ZH) has rear-facing ports. This orientation matches Troy-Bilt frames that require left-handed pump connections. It is designed for compatible vertical-shaft gas pressure washers. If your current pump faces the rear, this unit will restore your 2600 PSI output without modifying the frame.
Are the dimensions of both pumps identical?
The dimensions are nearly identical but not exactly the same. The front-facing pump measures 13 inches in length, 8.5 inches in width, and 8 inches in height.
