Hi JM, I believe the 28 crawler tractor used the same engine.
Unless it's really 1M88, you have a 112 grader made in 1942 from the information I have. Old Magnet has the engine specs pegged.
more grader info http://www.chriscomachinery.com/Graders.htm
Sorry about the mistake! The grader in question is an 8M88. No 212 gas motor single wheel drive. Bill
After looking at Erik's Chapter 12 info, apparently the motor is a 3-1/4 X 5 same as an R 2. Was this used in anything else and does it have a specific model no. ( such as 3400 or 4400 for example ) ? Thanks all!
That's 3-3/4" bore x 5" stroke 3400G engine.
R2 option is it.
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."
