I need help finding a exhaust elbow for my Cub Cadet 128 kohler. I am at the assembly pointing my restore and I'd like to get a new one if possible but I don't know where to find one. My current one has threads that are severely worn so I'd rather start new and never have to replace it again. Any help will be appreciated.

Is it a regular NPT elbow that is on there now?

Yes I believe so , I had put a steel plug in during restore. Engine threads are good but elbow threads are shot.

I have always gone to the hardware store and bought the NPT pipe I needed to make the exhaust how I wanted it or to keep it stock. Do you still have the locking collar from the old pipe? The locking collar is the only thing I am not sure on sourcing. I don't know if the 12hp Kohler has a reducer in the head. My Kohler 16hp does. The pipe thread size is either 1" or 1 1/4" NPT. You can take your old elbow with to the hardware store and match it up.

I know what piece you are talking about.  One side has male NPT, the other side is just plain pipe.  It is a gentle 90 degree elbow.

 

It is a Kohler part.  It is still available new for $116!  I've sold two, they are common pieces to need a little love, but not cheap.

 

Joe's Outdoor Power sells them used for about $20 if I remember right.

That is good info to know Ben. I didn't realize they had a special piece that was factory. Used one wouldn't be bad but I don't think I could justify a new one. None of the Kohlers I have ever worked on had anything different other than regular NPT pipe.

The collars are just a thick version of a conduit nut.  I use conduit nuts and have never had a problem.  Kohler will ream you for $10 to buy a new one.

I will definitely keep the conduit nut in mind. I thought they were too thin and would warp from the heat but that is great they work.

That price jumped here recently.  I sold them for $50 last year.  A price jump like that means that it will probably go NLA before 2015 is over. 

 

It looks like John Deere and Cub Cadet are the only specs that use that special pipe.  It is part number 235692.

Go to a good electrical parts house and they carry a heavier locknut for rigid conduit. Lowe's usually
has only the light weight locknuts.

Yes, you are right.  I should have clarified.  Lowe's (and even most Ace stores) carry a thinner stamped steel nut.  They do not hold up as well under exhaust heat.  A contractor supply store will have them, although you'll probably have to buy a box of 20 or so.

Yes that is the pipe I'm looking for , mine is badly pitted and threads are almost gone, I still have the
Original lock nut. I'm trying to stay as close to original as possible but $100plus dollars I can't justify for it. This cub will have a easy life if I ever get it done. Thanks Tom

This looks like something that could be replaced with conduit pipe.
