How do I know if I can change the oil in this Pressure Washer Pump

[massimofinance]

HI all, I need some help. I called Briggs and Stratton and they cannot tell me the model number of my machine, hence I cannot get my manual. I am posting pictures hoping someone can tell me if I need to change the oil and how. Is this a sealed unit that you cannot change the oil for? Thanks!!!

mass, I can't say from the pictures but I don't think the water pumps are serviceable. Meaning there is no way to change basically anything in them... But I can't see your setup well enough to verify that. I just know my pressure washer has no place to change oil or anything else... The engine driving it does, but not the pump.

Great, thanks, that is what I am assuming as well./.

You would think there would be a sticker somewhere stating what model it is, then you could google it to find the manual....... On the bottom of my pump I have a drain plug. Mine is a Comet ZWD. It's a larger system. 13hp Honda motor. I believe when I had a smaller system I was still able to change the oil.... I guess I would really search for that model number..... It's possible the sticker fell off.....

That pump was made by Devilbiss.
It is a non serviceable pump.
The metal straps will break before the pump itself goes.
You can get a drop-in pump off ebay for about 100 dollars.
They are pretty good pumps for the money.
