This is a common problem when the dog clutches are worn out.
These are large metal collars inside the Power Control Unit. The blade controls are always the first to wear out because they are constantly used.
Replace the clutches and the control will return to normal.
these dog clutches who would have these? and approx what is involved
with changing them out? s/n 64c53
I am sorry for the delay in my reply. I have been looking for a manual to match your machine. The only one I have currently is for a 99E model.
I am assuming a CAT dealer can get you these parts. I haven't seen one in so long I don't know if parts are still available.
If I can locate the correct book, I will try to get you some information on the Power Control Unit.
I finally found the 14 64C book. Below is some information about the Power Control Unit. The only adjustment is for slack in the worm gear, this would not effect the ratcheting problem you are experiencing. Parts replacement is likely the only fix. I have not done any of these, just going off of what the older guys taught me.
I hope this helps. If it is not correct, please let me know. If you find a number cast into the Power Control Unit, it may help locate it quicker.
is it possible to change the up and down of the blade to hydralics like
on the newer graders using the up and down of the front v plow hydralics that we no longer use the old girl is in great shape starts
in 20 below with out being plugged in its a shame to put her to pasture but if the blade dont go up and down its pretty much useless ???
Hi, thanks for the accept and the bonus! It is greatly appreciated.
I am sure someone could do it but, I would think the pump needs to be larger as well as the hydraulic tank. As the machine sits, the control would be very slow and you might not have enough oil to fill the cylinders and maintain a safe level.
If a wing plow kit could be located to fit it, that should have plenty of capacity. The pump would still likely need to be upgraded.
If your goal is to save money, try swapping the clutches for the circle side-shift and the scarifier or some other function you don't use as much. I think all the clutches were the same. Verify this with the parts page I sent you. I just don't have any of this "Old Iron" around me to actually work on them. I just enjoy the "war" stories from the older mechanics and operators.
Good luck! Please let me know if I can help you again.
