Yanmar Fuel Injector
#1

This is a HACK, that may save you a little trouble someday. I post this because the standard injectors for the  Yanmar 4TN84V are available in many markets. The exact match injectors for the Yanmar engine in our Kohler generators are apparently made of unobtanium. 

I was replacing the injectors in my Yanmar generator engine. I bought injectors on line to fit the 4TN84V engine. When I took the old ones out, the mounting arrangement and fittings on the old injector weren’t even close to the injectors I bought. Oops. 

But, the business end of the new injector including springs, shims, poppets, and nozzle fits the old top end. Since the top end is a simple non working part, I swapped the new injector parts to the old injector body. 

Lots of little pieces and cleanliness is essential, so disassemble and reassemble in a clean environment.

Worked great, no more smoking.
