Honda GX-390 seized

I have a 5 year old PowerEase pressure washer with a Comet pump and a Honda GX-390 13 HP engine . I have used it regularly(2-3 days a week) and maintained properly. Last year I slowed down using it only once a month. About 3 months ago, it was froze up and I had to break it loose very physically with a belt and a bar to get leverage.After that I could start it with the cord and every time I used it I would remove the plug and put oil in to help lubricate the shaft. This worked until last week and now I can't break it loose. Has it seen its last days? I don't need as big a washer nowadays, so is it more cost effective to purchase a new one? That particular model is about $1,100 and the least expensive GX-390 I could find was $600.00. Thank you for your time

The locking up isn't likely the engine, but the washer. If you had to break an engine loose like you're describing, it wouldn't run very long.

I tend to agree with marbobj, If this is a direct drive (pump bolted to engine) unit remove the pump and test run the engine again. Some of these pumps have a small hole in the side near the engine, This is to insert a allen wrench to loosen a set screw holding the pump shaft to the engine crankshaft.

You may find it cheaper to purchase a replacement pump for your engine (if it checks out fine) than the purchase of a smaller non-commercial machine.


Good Luck

Thanks for your response. It makes sense. I remove the pump & see what happens.

Thanks again

My GX 390 13hp did not come with a manual. I'm clueless as to where the hose to the wash bucket is suppose to be attached on the pump. Any help is greatly appreciated.

There should be a 1/4" barbed fitting on the manifold near where your pressure hose connects.
