Jacobsen 122f reel won't turn

I am having trouble with this mower. All of a sudden the reel won't turn. It makes a crazy racket when I try to operate it. I can turn the reel by hand in both directions. Also, I have removed the electric reel mower and verified that the shaft turns when activated. After digging deeper I pulled out the shaft coupler and decided that it doesn't feel like it is grabbing the splines as securely as it should be hence the terrible sound. However the engagement travel seems to be limited. The only apparent solution seems to be slide the reel and shaft towards the outboard electric motor. Does anyone know how to do that on a Jacobsen full floating head? I'll take a picture when I get home. On a side to reels disengage so they don't tear up if they get jammed?

Haven't had a chance to look at it but I remembered some more background information. The reel will spin in backlap mode. That makes me suspect the coupler even more. The internal gears look twisted so it makes sense to me that they could be worn in one direction but not the other.
Twisted was probably the wrong word. They seemed worn in one direction. I was able to purchase a new coupler in town this weekend. That didn't solve the problem. I decided to break down the entire floating head assembly to try to figure out why the reel is too far away from the coupler to provide good contact. I will likely replace the bearings and set the preload spring back to specs and see what happens. I'm pretty frustrated. My good deal is looking do good after all.
