My '51 CA is equipped with Power-Shift wheels, and I have been unable to find a wrench that was made to loosen the rim locks to change the wheels. Any ideas on something that might do the job? I have tried many different sized sockets, but nothing seems to work! Or possible someone might know of a place that I could get a rim lock wrench? Thanks for any help! I can't put a loader on my tractor until I reset the power-shift wheels.

If they are that stuck take the brackets off the center part of the wheel and loosen them up real good . The Ca Cam lock can be turned with a 1/2 in drive socket extension turned backwards and a wrench on the drive end. If they are really stuck and you try and force them you might twist the hex off of the pin. Mine were so stuck I had to take them apart and soak them real good and work them back and forth until I got them free.My Ca doesn't run yet so I could not spin them in or out with the engine, But I could not get the wheels between the fenders on the trailer to drag her home with them set wide.

I had to take the WE ones I had off the wheels and rims and free them up one at a time. Took the snap rings off the back and drove the cam back and forth with a hammer until I could turn it a bit, then worked it out. Open vise a bit and place bracket on vise and drive cam into opening in vise. Good luck, it can be a project, I did one or two at a time, then the next day a couple more. Took a big hammer too. Some heat might help, wouldn't want to heat them too much as they are hardened.

As I recall, the CA uses 1/2" (maybe 5/8") square head bolts on it's eccentric locks. Buy the proper size (high Quality) square socket. Usually these things are rusted pretty badly and they take a lot of torque to break loose. On WDs & WD-45s, I've had to resort to taking the wheel off the tractor and (after using plenty of PB Blaster) driving on the head of the bolts, then turning the wheel over and driving on the other end of the bolts to get them to "free-up" so they will turn. Good luck, sometimes they can be a beech!

I've never moved the wheels on a CA, but the procedure is similar to a WD/WD45. Use a six-point socket. WD takes a 3/4 inch. Start at the top of the wheel and work your way down, unscres the bolts about 3/4 turn CCW. That's as far as they go- they are eccentric cams. When all four are done- the wheel can be shifted. Step on the brake on the opposite wheel and drive either forward or reverse, moving the wheel in or out in the desired direction. You should have the stop installed in the appropriate hole if you are not moving the wheel the maximum amount. Then install the stop, either one or both sides of the casting on the wheel, and tighten the four eccentrics, starting at the bottom and working your way around the wheel to the top.

I have a narrow front CA. What is the purpose of shifting the wheels in or out? Stability or torque?

Stability and different crop spacing when cultivating or planting. Tim
