4430 belt replacement

I need to replace the AC and fan belts on my 4430. I know I have to take off the hydraulic pump drive coupler, but I'm having issues. I got the lock nuts off, but the 2 bolts won't come out. Are they threaded into the coupler? I tried turning one out and it got really tight. I was afraid I might break it. Any ideas??
Also, are there only 2 bolts?
If I get the bolts out will the coupler just come off, will it slide back and off?

Thanks
 
Yes they are threaded into the coupler, the pewter material they use in the coupler can seize to the bolts. Replace the coupler halves, bolts, nuts, and rubber bushings. Once the coupler is off(might have to pry these off too) just turn the pump shaft to allow clearance for the belts. The rubber bushings can be pried off or cut with a utility knife what ever you have available.

Thanks for the reply.
The bolt turned at least a half turn when I tried, but became tight after that. I was using a long 1/2" extension and breakover bar. Should I just try harder or is there some trick to this? Just not sure what I would do if the bolt broke.
