np205 Rebuild Question....Idle Shaft

I just installed the idle shaft and gear in the np205 I am rebuilding. I know you are supposed to install the shims and spacer between the bearings and check the end play. I thought I was good with zero end play, but then I installed the idle gear/shaft into the case and torqued the shaft nut to 135 lb.ft (also read it is supposed to be 200) I installed the same 3 shims that came out of the assembly. I had new races put into the idler gear. When I tried to torque down the nut it just froze the gear assembly. I backed off the nut and reset to about 75lb.ft. It spun freely without any binding and there was zero end play in the gearset. Do I need to pull it out and add a shim so I can torque to 135 (or 200) lb.ft? Advice from anyone with some experience here would be much appreciated. Thanks
John
