212 Grader King Pins

Hi, dsburdell.
The 212 is a whole different beast from the Cat 12 machines in quite a few ways, this being one of them. I have a bit of experience on Cat 12s but have only operated a 212 for about 1/2 an hour. The front end of your machine is vastly different from that of the Cat 12 which I had top dismantle and rebuild some years ago in Perth. That didn't come apart easily either - to the tune of a 28-pound hammer and a LOTTT of thumps - - - might have even been some 'harsh language' a couple of times.

You haven't shown your 'lo-kay-shun' on your post. It is very often a good idea to have that showing 'cos there may be someone living near you who might be able to help.

We do have a couple of people haunting the forum who have a wealth of information at their fingertips and a few also who own 212s. I suspect that one or more of them will chime in shortly

Just my 0.02.

What is your ser#? There may be some differences by year. I have several parts books
But first, I would check the availability of parts before getting too serious with the hammer.

Stephen the serial number is 95C135 , 212 made in Aust , the closest manuals I could find for it was a 9T Parts book and a No 12 service book,
Even Hastings Aust couldn't give me any info on it , found out more info on ACMOC
Thanks

Hi, dsburdell.
You might be surprised about members being near your location. There could well be a gentleman named Lance Jones come along and read through this thread. He would be able to tell you better than probably anybody else if there are any other members near you. He is the current president of the Qld-based ACMOC Chapter 18.

You could try calling 13 12 28, the Caterpillar Distribution Centre at Yatala, and ask them if they have anything on it. That centre is one of - currently - 8 around the world that are the major distribution centres for Cat parts.

If your unit was made in Australia, I think that would make it a post 1953 build, 'cos I think that is when Cat started assembling graders themselves here Australia, after buying out Steelweld who had been building graders here under license for some years after WW2.

Ok Danny, I got curious about your pin. I have a 9T 212 and a few books so I did some digging. I think the 9T and later 212 look the same in that area. The pin B is the lever that leans the wheels, so it has a key or splines to turn the knuckle. The operator manual and the parts book are clear as mud on the retention if any on the king pin.
If your dealer will pull a drawing on the pin you could see if there is a cut out for pin B. Also a drawing on the leaning arm would be helpful. On the pin B/lever arm I would heat the knuckle as much as I dared and try not to bugger the threads when tapping on the end. The parts book does show key 1B8730 associated with B

Thanks Stephen ,great help

It looks like a Chevy truck!! Look down the side of the king pin from the front side. There is a bolt with a nut. Remove the nut. Then drive the bolt out. I think that is a tapered pin not actually a bolt.The threaded end is the small end.
