Troy-Bilt 020245: Gas-Powered Direct-Drive Pressure Washer Pump Service and Seasonal Maintenance
The Troy-Bilt 020245 uses a single-cylinder OHV gas engine driving a triplex pump through a direct drive connection. Pump seal failure is the most common cause of pressure loss and water leaks on this model. Pump seals are especially susceptible to cracking when the pressure washer is stored in freezing temperatures with water left in the pump cylinders. Annual winterization with pump saver solution at the end of the season prevents freeze damage to the pump seals at a fraction of the cost of a seal set replacement. The pressure washer repair help section covers 020245 pump seal replacement, unloader valve adjustment, and spray nozzle cleaning.
Most Replaced Parts on the Troy-Bilt 020245
Pump Seal Set for the Troy-Bilt 020245
The pump seal set contains the piston seals and valve seals that maintain pressure inside the pump cylinders. A seal set cracked from freezing or worn from extended use allows water to bypass the pistons, reducing output pressure and producing visible leaks from the pump body. Inspect the pump housing for cracks before ordering only the seal set.
Spray Nozzle for the 020245
The spray nozzle controls the fan angle and pressure at the output of the gun and wand. A nozzle orifice enlarged from wear or debris reduces maximum cleaning pressure even with a healthy pump. Clean nozzles with the provided cleaning wire rather than a drill bit, which enlarges the orifice permanently.
Unloader Valve for the Troy-Bilt 020245
The unloader valve diverts water from the pump output back to the pump inlet when the spray trigger is not depressed, preventing the pump from dead-heading against its own pressure. A stuck-open unloader valve causes the unit to run but produce no pressure at the output.
High-Pressure Hose for the 020245
The high-pressure hose connects the pump output to the trigger gun. A hose that is kinked, cracked at the crimp fittings, or has ballooned from internal delamination must be replaced immediately to prevent sudden failure under operating pressure.

Troy-Bilt 020245 Pressure Washer Parts FAQ
What is the Troy-Bilt 020245 pressure washer and what engine does it use?
The Troy-Bilt 020245 is a gas-powered residential pressure washer. Gas-powered Troy-Bilt pressure washers in this class use a Briggs and Stratton or Honda single-cylinder OHV engine driving a triplex pump through a direct drive connection. Confirm the engine brand from the engine data label on the unit before ordering engine-specific parts such as the carburetor or spark plug.
Why does my Troy-Bilt 020245 lose pressure during use?
Pressure loss during use is most commonly caused by a worn pump seal set allowing water to bypass the pump pistons, a clogged or worn spray nozzle restricting output flow, or an unloader valve stuck in the bypass position. Inspect and clean the spray nozzle before disassembling the pump.
Why does my Troy-Bilt 020245 leak water from the pump?
Water leaking from the pump body indicates a failed pump seal set or a cracked pump housing. Pump seal sets can be replaced without replacing the entire pump assembly if the housing is intact. Inspect the pump housing carefully for cracks before ordering only the seal set.
How do I winterize the Troy-Bilt 020245 for storage?
Run pump saver solution through the pump until it exits the discharge outlet. This fills the pump cylinders and seals with antifreeze and lubricant that prevents the pump seals from drying and cracking during storage in freezing temperatures.
