so i have been having issues with my 330 overheating since day one. talked with eddie at esr and gave me a few things to check/try. one of them was to make sure the impeller had the small washer behind it. i checked it did. started reassembling and some how broke the shaft when torquing the impeller nut back down. i dont understand how i ,had the damn torque wrench on 8 ft lbs. any suggestions so if and when i get a new shaft i dont do it again? i am nearly thru dealing with this damn R. if someone could help me out it would be greatly appreciated. i am almost to the point of parting it out as it has been giving me fits since back in june when i started the break in process.
o and by the way i started a wanted post for a shaft if anyone has one

are you sure your tourqe wrench is calibrated acuratly ?
-
i have used it on everything else. could be outta wack i guess. maybe i will try my mechanic buddies high dollar wrench next time to eliminate any doubt.

Just because it is high dolar doesn't mean it is calibrated correctly. Or has been stored correctly. I would us an in/lb and set it to 96 in/lb. I don't like to use a wrench at 1 end of the specktrum it is designed for.
