Dandy Dave Posted September 10, 2015 Share Posted September 10, 2015 (edited) Not exactly an automobile, But think for a moment. If these great road building beast's were never built, where would our highway system be today? This is a Caterpillar Model 12 that was built in 1940. It is a very Rare Gasoline version. Only 56 of these graders were equipped with a gasoline engine. This is the only one we know of with traceable serial numbers. Was not much left to the intake in the heat riser, But I persevered and It lives again. Enjoy.

R Walling Posted September 10, 2015 Share Posted September 10, 2015 My first thought was that it's time to get some paint on that , but then I thought that you are just going to mesmerize us with the patina , (good choice on the latter.) 1 Link to comment Share on other sites More sharing options...

Dandy Dave Posted September 11, 2015 Author Share Posted September 11, 2015 (edited) Thanks folks. Digging through some old info.This engine is 468 CID and develops 75 Brake Horse Power at 1,600 RPM. It is 4 and 1/4 Bore and 5 and 1/2 Stroke. The engine alone weighs 2,700 LBS. This old Caterpillar Model 12 Grader Weighs in at 22,000 LBS. That's 11 tons of iron. I got the air cleaner on her yesterday. Working on the Battery box. She's rusty. Dandy Dave!

jeff_a Posted September 11, 2015 Share Posted September 11, 2015 Would steam shovels and steam rollers have still been in service in 1940 when that was built, or were they gone by then? Link to comment Share on other sites More sharing options...

Dandy Dave Posted September 12, 2015 Author Share Posted September 12, 2015 Would steam shovels and steam rollers have still been in service in 1940 when that was built, or were they gone by then?They were still running Steam at that time, Although it was on it's way out. When large Diesel engines became compact and reliable, that was basically the demise of Big Steam. Dandy Dave! Link to comment Share on other sites More sharing options...
dei Posted September 12, 2015 Share Posted September 12, 2015 Dave,I will have to get a picture of a huge steam roller that our club saved from the scrap yard years ago. I'm 6' 4" and the wheels are about that tall!I heard some of the guys tried to fire it way back not knowing what they were doing and guess there is a lead relief plug that melted for safety! It sure is a beast! Love you grader! Link to comment Share on other sites More sharing options...

62BillT Posted September 13, 2015 Share Posted September 13, 2015 A lot of people like patina, but to me, there is nothing like brand new paint. Cool machine by the way. 1 Link to comment Share on other sites More sharing options...
Dandy Dave Posted September 13, 2015 Author Share Posted September 13, 2015 Agreed, Especially on rusty vintage construction equipment. It sits outside and paint helps preserve it in this case. There is just so much cleaning / sandblasting too be done on something like this. With all of its moving parts, sand blasting would not be the best way to go. Too great a chance to get grit in a gear box or somewhere else that it does not need to be. Think antique cars are expensive to fix? This yellow iron is just as bad, and most of the time worse. Still an excellent way to make money backward as my Dad would say. Dandy Dave! A lot of people like patina, but to me, there is nothing like brand new paint.

capngrog Posted September 13, 2015 Share Posted September 13, 2015 D. D., That engine sounds great, and the oil pressure appears to be excellent. Will you have her ready to plow for the first snow fall? If it doesn't move, paint it. If it moves, grease it. Cheers,Grog 2 Link to comment Share on other sites More sharing options...

1937hd45 Posted September 13, 2015 Share Posted September 13, 2015 Long shot but does your grader have "MOLLY" painted on the front arm? If so it was part of the Highway Department here in town. As a kid growing up in the 1950's I can remember her working all year long. Notice the color difference, was that the radiator that someone stole and you've replaced?

Dandy Dave Posted September 14, 2015 Author Share Posted September 14, 2015 (edited) This Grader Belonged to the Town of Milan, NY. From there it went to Christiana Brothers Excavating just around the corner from where I live. Yes. That is a replacement radiator from a diesel model that I was lucky enough to find. Dandy Dave!

Dandy Dave Posted September 14, 2015 Author Share Posted September 14, 2015 (edited) Yes. All the Big Cats had Gas Engines in the early years. They did build a few model 60 Diesels in 1931. Red River Lumber Company did some conversions on Cat 60's as early as 1927. The Gas engines were replaced with Atlas Diesels. The Diesels were beginning to become reliable by the late 1930's and were really perfected over the course of WWII. The D-318 Engine built after the war and used in the D-6 Crawler, as well as many other applications, is one of the toughest old Diesels Cat ever made. Yes, Until the early to mid 30's they all had gas engines. The engine in my 1940 Grader designated as a G-4600 was based on a D-4600 engine of which they built 1,000's. It was the forerunner of the D-318. The G is for gas, and the D is for Diesel. It is estimated less that 100 of the G-4600 gas engines were ever built. Of this, 56 were installed in Model 12 Road graders. Mine is Serial 6M-17. There is one other know to exist out on the west coast but it has no serial plates. Dandy Dave!

Dandy Dave Posted September 16, 2015 Author Share Posted September 16, 2015 It is getting better everyday Larry. Did quite a bit to repair the rotted out Battery Box today. Oh. Everything is Big on this old Caterpillar. Must be from Texas. The battery Box is made from 1/8th Plate Steel on the sides, and 1/4th plate steel on the bottom. It is approximately 24 inches high, 11.5 wide. and 27 inches in length. Photos to come in the day light. Dandy Dave! 2 Link to comment Share on other sites More sharing options...

avgwarhawk Posted September 22, 2015 Share Posted September 22, 2015 I love seeing these old beasts come back to life. I remember playing on old abandoned dozers and such when I was a kid. They had their own particular smell mix of fuel, rust, grease and earth. 2 Link to comment Share on other sites More sharing options...
Dandy Dave Posted September 24, 2015 Author Share Posted September 24, 2015 Power Steering was an add on and not original equipment. The Christiana Brothers Excavating Company had the unit partly removed about 30 years ago. When I got the grader about 10 years ago, I finished removing it and installed it on a 1955 Cat Model 212 # 79C42 grader that they have. The 212 grader is one of around 100 built at the time with Factory Glow Plugs and Direct Electric start. The other thousands of 212's built at the time had pony motors. The PS is not original to either machine, so not missed at all. Dandy Dave! Looks great. Looking closer, did you miss reinstalling the power steering on the grader?
