Parking brake clarification

I'm installing parking brakes on my 850 and need some clarification as to the brake pawl operation. My tractor has the brake pawl arm, brake camshaft lever, brake pawls and parking brake levers installed, however the brake pawls appear to be rusted in place and I am soaking them in PB Blaster.

Based on photos of other tractors, the parking brake levers are not in the proper position.

The archives also indicate some damage can be done to the pawls, arm or camshaft lever while trying to free them.

My question is; how much rotation the pawls actually have in the camshaft lever and brake pawl arm? Are the pawls keyed in some manner to limit movement? What's the best way to free them? I don't want to do any damage trying to free them. The Manual offers no help. I hope I've clearly explained the situation. Thanks in advance.
 
Glen,
I have seen lots of those pawls rusted up solid. You can try soaking them with penetrant for several days and then use a wrench or pliers to try to rotate them. There is nothing inside that limits their movement. If penetrant doesn't work, heat from an acetylene torch certainly will. Didn't you recently paint the 850?

Hi Alan;

Thanks, I picked up the additional parts I needed from John Smith and will try to free up the pawls so I can have parking brakes. As for painting, yes to the majority of the tractor, I painted it about four years ago. However, I've been doing some odds and ends. I had a lift cylinder go bad and the repair shop did a great job tearing up the paint. I repainted it two weeks ago and guess what, the new seal didn't hold. Took it back and they said they would try to protect the paint this time. I have the fenders to do again because I wasn't satisified with the script. Had some wheel weights I recently painted that turned out pretty good and are now installed. There'so doubt that I suffered a severe case of mission creep. For some reason I keep finding theings to do. :) It's been a learning experience, I'd do some things differently if I was to do it again. As always, thanks for your help.
