Small Engines (Lawn Mowers, etc.): Sears pressure washer, pressure cracks, pressure relief valve


Question
Hi John! Remember me? Tate's Auto Service, retired. John, I have a Pressure washer (Sears 580767200) that started leaking the pressure pump oil out the  upper housing 1-5 psi pressure relief valve. Water is in the pump oil. So....I take it that there is a seal that is allowing the high-pressure water to enter the oil. I have not taken it apart yet. Most likely seal? Here is a link to the pump.  http://www.searspartsdirect.com/partsdirect/part-model/Craftsman-Parts/Power-was...   Thanks, Bill

Answer
Hi Bill:

>>Long Time. It's Great to Hear from you again. I Hope All is Well with You and Yours.
>>From your Description it Sounds like an O-Ring Seal has Blown and Requires Replacing.
>>Usually when this Problem Occurs, I Suggest Replacing ALL the O-Rings inside the Pump when it is Repaired.
>>Be sure to Check the Pump Housing for Cracks (including Pressure Cracks).
>>We have 2 cans of Spray that are Used to Locate Pressure Cracks in Aluminum (and other metals).
>>I will Locate the Information about this Product (Crack Detector) and Supply it to you if Required.
>>Thanks for Remembering us at All Experts.
>>As Always, If you Hit a Snag, have More Questions or this Does Not Correct the Problem,  I Hope to be Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.
