But it happened because new types of the injection pump was introduced on the diesel engines...
And all models of the 722.1 generation have fundamental (identical) inner structure.

I'm sure they had a good reason for it but when they put in a different valve body to accompany the change they left the id number the same. I find it confusing because now I need to know about the secret squirrel serial number information that says all 722.118 transmissions past serial number blah blah blah were vacuum only...

...if they had called the revised 722.118 a 722.199 for example then geezers like my good self would immediately be aware of a difference.

Besides an early 722.118 has a more similar internal structure to a 722.112 but less so than the later 722.118 - the differences are small - like a different valve body. But that was the change made to the 722.118 so I don't see why the new version didn't get a new number...

...just saying...

...just ranting...

...not at all frustrated...

...not at all over excited by it all!!!!!
