The oil drain valve on my propane generator started to leak, I went on the usual parts chase for a 1987 generator. I was finally put on to jacks small engines and what a stroke of luck that was. I simply typed in the Onan part number without any reference to Onan and up popped the part. When I received the new part the valve/tap was jammed so I emailed them, what do you want me to do, send the non working part back or wait till you send a replacement. Email reply was don't worry about the first valve we'll send you a new one.
When did the tectonic shift in customer service happen I haven't experienced this kind of service in years. I can't recommend jacks small engines enough.
For what it is worth, I replaced the end bearing on the generating end housing.
The part #6205LLBC3/EM is a NTN bearing number and under $10 at a NTN bearing supplier.
Jack's is where Mr. Tinkerer gets most of his small engine parts. In fact he is waiting for a carb. that they were able to have when no one else could find the correct one. Always great service.
