Questions: I am rebuilding a 4-134 f I cant find an exhaust valve that matches the one I have.
The shaft is 12/32 in diameter
the outside diameter of the valve is 13/32
the inside diameter of the valve seat is 8/32
The length of the valve is @ 5.75 in
The valve clip holder at top of valve is 7/32 deep. Then this has a .25 in hold space/ then has a .5 inch taper to the shaft width
do you have a replacement valve like this? It is stamped Eaton 28EX

If you have the valve that accommodates a tapered shaft where the retainer is that is available used only.
