'88 Winnie Super chief genset ????

[Gary - K7GLD]

The Onan genset on our '88 Winnie Super Chief runs great, but with it's age and not knowing about PO maintenance, I figured checking spark plugs would be a good idea. The outer one was easy, and I found it to be pretty crudded up, and cleaned it. The one over on the INSIDE though, seems to be an entirely different matter!

I see there are what appear to be slides on either side of the genset that would allow the entire genset and box/housing that surrounds it to be slid out- but if that was done, the genset would still be inside it's enclosure, and the inner side of the genset inaccessible still.

There is also a "swing-down" arrangement that appears to allow the genset to be sort of dropped and swung down for access to the inner side of the genset now free of the outer enclosure - but not sure of how that is accomplished with the exhaust system and large wiring bundle in place?

The exhaust system/hangers might not be too big an issue - but I don't see any provided slack in the wiring bundle to allow any appreciable freedom to allow the genset to significantly be slid/tipped out for service.

I figure that inner spark plug has probably NEVER been serviced or replaced - but dunno if the job to check it is worth the apparent hassle to get it done!

Anyone with the same or similar rig had their Onan genset swung down or pulled out for access to the back side?

It is possible to change the inner plug by swinging the unit all the way down with a jack but you'll have to disconnect the electrical supply line . That should be in a flex conduit that's attached to a standard house electrical junction box there is a locking ring inside of the junction box that attaches the conduit to the box probably underneath the bed, somewhere within that vicinity. It'll be wired just like a standard house black, white and green. It'll be tight quarters but you can do it.

BTW: Watchout for the exhaust hanger towards end of pipe
