212 Question

What he said!

You are going about it the right way, the power shaft under the cab turns at engine rpm and can be easily ratioed up or down with pulley selection to run a hydraulic pump for the steering or on later models (12E for example) it direct drives a hydraulic control unit that mounts on the front of the cab so you can run a hydraulic side shift moldboard.

on my old 9K we took the power shaft off from under the cab and fabed one up with a pulley in the middle. then mounted a small hydraulic pump under the floor and plumbed it into a charlyn unit in the steering shaft above the frame in front of the operator. it worked great and made steering a one finger affair.

The Behlin power steering unit I installed on my 212 has a belt pulley for the pump built into the front u-joint on the live shaft.

Thanks for the insight. I will stick to my v-belt pulley on the power shaft under the cab. It is nice to have bad ideas shot down before I spend time and money on them..

Have a complete Belehn unit on a 9k cat 12 I am parting out. Have no idea in what shape. everything else is completely worn out on the machine

The 212 i had had a pulley that bolted to the universal joint yoke on the input shaft of the power control box. So the pump and reservoir or filter, (can't remember exactly which was on the pump itself) was under the floor of the cab. The only thing that might be different is the bolt pattern in the pulley.

I have all the parts, and am now just troubleshooting why I don't have enough flow or pressure to drive the unit. My original question was driven more by the fact that it is easier for me to work standing alongside the grader than sitting under it. My tag line says it all.....😖mile:
