Farmall 140 spark plug problems

Mel Shaw · Mar 7, 2011

I have a loose spark plug in my Farmall 140. I cannot find a helicoil for a 18 inch spark plug. Anyone know where to find one or can help me fix my problem?

The 18MM inserts are READILY available, but the kit is COSTLY. McMaster, for one, has them.

GOOGLE "18mm spark plug thread repair kit" for LOTS of sources.
