Typical torque readings for yoke and din inlets are 18-20 ft*lbs...
You are not suggesting the torque is 230 and 150 FOOT Pounds??? This will likely ruin your reg. May be INCH POUNDS!
The real torque setting for inlet fittings is typically 18 to may be 20 FOOT POUNDS! The center screw retainer is way less to allow its removal without removing the inlet fitting all together. I want to say 10-15 INCH POUNDS....
100% mistype. inch lbs. Straight from my reg manual it says;
"DIN housing must be torqued to 230 inch pounds. DIN retainer torqued to 150 inch pounds."
