Pressure washer problems......?




Bob


I have a Honda GC 190 Pressure Washer that doesn't start properly. Very hard to pull the cord. So I checked the oil and the oil came pouring out even though it was on level ground. Now I am thinking that I need to change the oil even though I just did that a week ago. The oil that came pouring out was very runny its like water got into it although I doubt that is possible.

My question is what type of oil should I put in it? (I had SAE-30 in it already)
thinking about filling it up with this --- http://www.walgreens.com/store/c/pennzoil-motor-oil/ID=prod6015629-product

Answer
I think your engine has a major problem. If there is any fluid in the combustion chamber, it will be very difficult to crank it because neither oil nor water is compressible. If more oil drained out of it than the amount you put into it, either water or gasoline is leaking into the crankcase causing the fluid level to rise up to the combustion chamber. It sounds (from your description) like it's gasoline leaking into the oil,thus thinning it out. Water doesn't dissolve with oil and usually turns the oil a milky white color which is easily seen. You can remove the spark plug and pull the starter rope. if any fluid is in there, it will be ejected through the spark plug hole. If so, you'll have to find the cause and repair it before trying to start the engine.

how do you pull pressure washer pump off the engine honda 3/4 keyed shaft.?

I need to replace a pressure pump and unbolted it and can not get it off.


Answer
I use a pickling fork a u shaped wedge tool with a strike end.

The keys are a harder steel than the crankshaft and often fret the crank. one solution over the years has been to use a silicone glue type product and literally glue the two parts together.

Because of the high rpm 3400 and pressure combined with water these things can be very difficult to separate.

some pumps will come with threaded ports on the ears to provide a means to separate the pump from the motor. Use caution as it is easy to break of the ears if too much for is use on the bolts.

drain all the oil from the pump before you start. Try the flat bar method above as some times you get lucky.

If that does not work you need to use the pickling fork and a mini sledge or very large hammer hit it form all four directions working around the shaft. sometimes a large wrench is needed as a block as the unit separates.

It often takes a huge amount of sweat time and force to separate these two.
