  • Heat Riser function

    OK...I'm pretty sure I installed my NORS heat riser on the 63' 289 correctly. I even filed down the inside of the pipe so as to have a clean action without rubbing.....so: I think the thing is not working correctly. I say this because the weight doesn't move no matter what temperature the engine is. Absolutely no spring action at all. When installed and looking down and from the outside, the counterweight is sitting covering an position of 6-9(on the clock). In this position, the weight (cold) holds this position. If I rotate the weight clockwise to about 11-2, not only will it hold in that position (it can stick) but I get the nice throaty dual sound of the exhaust going down the road, especially with deceleration. NOW: Do I have this installed wrong ?? More specifically: when the thermostatic coil gets HOT doesn't it expand and spread out moving the weight ?

    I think you have installed it upside down the way you describe it. The weight when cold should be at about the one or two o'clock position, as the spring heats up the weight will drop to about 5 o'clock.

      Yes it is upsidedown, but the sticking could be the butterfly hitting the Exhaust Manifold, and you will need to grind a little off of the heat riser butterfly to correct it.

      Is this NORS one, the Repro with the half round counterweight?

            It is that little removable plate on the side of the exhaust manifold, there is a cover & 2 bolts, valve & shaft, thermostat (spring), balance weight, Valve bushings and Gasket in there!
            All available at Studebaker Vendors at studebakervendors.com

            It does not connect to the intake manifold, it merely heats it.

                    Lots of pictures of my Champion 170 heat riser here:
                    http://stude.vonadatech.com/EngineManifold.htm
                    The 185 should be similar or identical.

                        I believe the Carb. Automatic Choke heater pipe could only go to the Carb. Automatic choke!

                        It may help to consult Pg. 10 of the Engine Section of your 1955 to 1958 Studebaker Chassis Parts Catalog for a pic. of the Intake/Exhaust Manifold.

                        You cannot maintain a Studebaker without using the Shop Manual and Parts Catalogs.

                            On most 6 Cyl. engines, there is another tube with a enlarged end that slips over the one in the manifold with a big curve at the top and a flared end with a compression nut to allow it to screw onto the threaded nipple on the Auto. choke housing.
