Did to replace the cracked belleville washer?
If you didnt replace it with the correct size bellleville the regulator wont work at the correct pressure.

If i recall correctly the high pressure stack of bellleville washers the washer are slightly thicker then the low pressure stock bellleville washers so dont mix them up.
