9020 engine issues

Recommended Posts

David Bagley

Hello all, 

I have a 9020, that has just had a 19.5 rebuild. After running the tractor for a while and shutting it down, it begins to drip a good bit of oil. All of the gaskets are new and just replaced, however not certain what to do. I was told to replace or look over the "breathers" ?? I am not certain where they are or how to determine if they are clogged? any/all help is appreciated.

Welcome to the club David.

The first thing I would do is download the Onan CCK parts manual.  They are online & relatively easy to find.

Cleanliness is important to determine where leaks are coming from.  It may be as simple as leaking around the drain plug or the gasket under the cap on the dipstick or the oil filter base. 

Depending on your level of comfort will determine if you start exploring crank seals, sump gasket, timing cover gasket or deeper.  The breather tube is the smaller tube which splices into the larger air filter intake tube.  Breather will be at the other end of this smaller tube.  Valve cover gaskets could also leak but I wouldn't think they would leak very much.

Another option would be to have the individual who "Rebuilt" the engine take a look at it & inquire what the "Rebuild" consisted of.

Others I'm sure will chime in.  I hope this helps you.

Welcome to the club there is a wealth of information here just for the asking. As has been said you will have to check to see just where it is coming from, it could be a bolt that loosened up and just needs retightening.

David, welcome to the club

without seeing your engine would be really hard to determine where oil is coming from

Like was stated , person who rebuilt would be my first place to look.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
