1942 Cat 212 Motor Grader

Hi, PatW56.
Interesting questions. Firstly, there is no 'arm' that swings the blade in a circle. There is a geared rack that shifts the draught frame from side to side, an arm on either side connected to the draught frame lift links to raise and lower the blade and a circle drive box within the draught frame to turn the grader circle one way or the other. If memory serves me right, the earlier versions may not have even had the geared rack for the side shift, just a link from the main frame to the draught frame with a couple of pin holes for adjustment.

To the best of my knowledge, the consumables are still available and so are many of the parts, especially for the engine. That 'missing arm' may be something that you would need to find from a 2nd had parts supplier.

If you can post a photo - or six - people here will have a better idea of what you are talking about.

Just my 0.02.

In a non operating condition they sell for scrap price discounted to the site of the grader. In other words if the price of scrap times the weight of the grader equals $800 and getting it loaded and delivered to the scrap yard costs 200, its worth $600.

Of course if you want it, you might have to sweeten the deal, but I don't think there is anything particularly valuable or unique about a 1942 model grader that would make it command a higher price than a later model.

Tires are not so available, at least in the typical grader tread. As I remember, several years ago, spade grip (tractor) or universal tread (military) tires were available while the industrial loader/grader tread was not. I would check availability if you are desiring a machine to restore.

Engines have serial number plates as well and should match the chassis plate. A 42 should have a D3400 3-3/4" bore 4 cylinder engine if a diesel model. Not sure exactly what gasoline engine would have been used.
