Need to sort out what 212 you have, preferrably with a s/n.
A 5B9297 injector is the early style that uses a set screw on the pre-combustion chamber.
Later D311 engines don't have set screws and use a different injector arrangement.
Both styles screw in to the pre-combustion chambers, not directly into the head.

S/N 1R734. That is exactly what I thought they did. Thread into a dry hole like some I.H. s. I also didn't know it was a D-311. My operators manual shows graders with two different engines and classify them simply as "earlier" and "later". I have both manifolds on the same side. Is that the 311?
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
