CAT 436C 4X4 steering tie rod inner nut removal

[rogerinutah]

Trying to replace the right tie rod and the Hydraulic power steering shaft is turning.
This front axle is a German ZF unit with the steering ram on the front. In the service manual it only shows the 2 wheel drive front axle. The 2WD has the steering unit at the rear of the axle, and shows a square nutplate between the hyd ram shaft, and the inner tie rod connection.
My unit w/4WD does not have the nutplate.
How do I stop the ram from turning ?????
Thanks in advance...

One end of the cylinder has two flats for an open end wrench if I remember right. I put new tie rods on my 416C about 3 years ago and the came off fairly easy.
