Exhaust pipe.

[BairleaFarm 340]

When using pipe for exhaust stuff do you coat the threads with anything before you install them?

You can put a little oil or hi-temp anti-seize on the threads to make the pipe turn easier, but as far as sealant..... No - you don't need to put anything on the joints. (it will just burn off)

The anti seize burned off. I was thinking something that would help release the pipe if need be.

I haven't run across anything that won't burn off. The heating and cooling cycles produce moisture that eventually rust the pipes and fittings together as though they were welded.

The only way they "easily" come apart is to heat them red-hot with a torch and unscrew them before they cool. The piece in the exhaust port can be split with a hacksaw blade and collapsed with a flat chisel. You still have to be very careful not to break a chunk out of the block at the exhaust port.

Ive got a piece that will be a pita to get off the k341. That is the 16hp right? I think when I get this other tractor working ill put it to sleep and soak it with some pb blaster.

Yep... the K-341 is a 16hp.

It should have the 1

It may, I guess that doubles the change of getting one of those fittings out.

About the only way one is likely to come out is like TT said. Cut a groove in one side with a hack saw blade, and use a punch to collapse it away from the threads. It's a wonder I never broke a block trying to screw those things out. Once I heard of that little trick, the world became a much quieter (as in less swearing in my garage) place.
