I'm installing a mechanical oil pressure gauge into my IH Cub Cadet 782. It has a Series II Kohler KT-17s.

The gauge I purchased comes with a bunch of adapters, but nothing that fits the small oil pressure port on the side of the engine.

Is there an adapter available?

If not, does anyone know the thread size and I can make one out of a piece of brass.

Thank You in advance!
 
I went to the hardware store and 1/8" NPT is much larger. The plug appears to be 5/16-24.....Looks like I'm going to have to make an adapter
 
The plug that I removed is absolutely straight threads. I measured it with my micrometer. I wasn't aware there was a 1/16 NPT. I flunked plumbing.....

I'll have to visit a plumbing supply house as the smallest the hardware store and Lowes had was 1/8 NPT
 
KH-52-158-05 is the part number for the 1/16" NPT to 1/8" NPT reducer if anyone else breaks one off, or is converting their Cub to a mechanical gauge.

I converted my block to 1/8" NPT by drilling it out after I snapped off the reducer and was unable to remove the broken piece.
 
Bought KH-25-168-05 from dealer. Wish I'd seen this before. No longer sold as brass fitting, now steel. How much, don't ask!!!!!!
