Touch Control block

CNKS · Apr 14, 2010

I managed to get the springs mixed up for the control block/reservoir on my Super A. For someone who has had the unit apart, there are two springs, one for the safety valve and one for the regulator. One is longer and heavier. From the diagrams in the service manual and parts book it appears that the longer one is for the safety valve. The diagrams are are usually approximate, and it is difficult to be sure that this is correct. The longer spring portrudes above the block if used for the safety valve but will be compressed when the block is bolted down. It seems logical, to me anyway, that the safety valve would use a stronger spring, since it is designed to relieve pressure that exceeds 1200 lbs. Does anyone know if the smaller spring is for the regulator, larger for the safety valve? I won't know if it is correct until the block and fittings are installed, and don't want to have to disassemble again.

Looks like No 18 is the longer spring in this parts breakdown which is the safety valve spring. Looks like No29 is for the pressure regulator. Hal

Thanks, I also looked in the I&T manual after I posted. Diagrams are actually clearer than in my parts book and service manual. The one for the Cub is even better. Different block, same function. So I'll use the long one for the safety valve.

yes use the longer spring as the safety one, just rebuilt the one on my cub.
