Well today I was halfway through doing a driveway and I noticed the machine was bogging down while holding the trigger, I let off and there’s milky oil coming out of the pump (I think through the filler)
Anyone have a simple diagnosis? If it’s the pump i’m going convert to belt driven…
I think you may have that backwards. Belt driven pumps are usually set to spin around 1450 RPM’s. You can change that of course by using different size pulleys. Belt driven pumps generally last the longest because they are spinning the slowest. Direct drive pumps are pretty much garbage for the contract cleaner because there spinning at the same RPM’s(3600) as the engine which cause direct drive pumps to by far have the shortest life Span.
Gear driven pumps are a major space saver but they also spin the pumps faster which leads to a shorter life Span. Gear driven is ok but belt driven is the best as far as longevity goes and how many hours you get out of a pump. Time=money and the longer then pump runs the more money it’s going to make.
