Excell Power Washer Engine Repair: RATO R180

A customer dropped off an Excell pressure washer and said he could not get it to crank. The unit looked new. In fact the pressure washer line was still wrapped in the original wrappings. The washer is an Excell EPW1792500 and according to manufacturer’s specs, it is powered by a 179 cc (6 hp) engine, its axial cam pump can deliver a pressure of 2500 PSI. This engine is also used on some Homelite Pressure Washers.

The engine was eventually identified as a Rato R180-3 which is used by a large number of manufacturers. A little research revealed the engine is made by Chongqing Rato Power Co., Ltd. If you need a repair manual, you will find it here.
