Replacing Heater Valve
« on: August 02, 2015, 10:21:30 »
I have completed the process of unsticking my heater valve following the terrific instructions in our Tech manual.

However, even though the valve is now freely moving I still have a problem.

The square top (with the hole in the middle for the screw:  http://www.sl113.org/wiki/Electrical/HeaterControlValve) of my brass heater valve has had the 4 corners worn down (I think from the valve being previously stuck and attempts to force the valve to move) so that there is no longer a snug fit with the control arm that turns the valve.

As a result as I slide the cabin lever the control arm moves quite a bit BEFORE it starts to move the valve and consequently I can't get to a full close/full open position.

The only option I can think of is to replace the brass valve completely with OEM or repro but I have not seen them for sale anywhere (I can't build-up the square edges of the top of the valve)

Does anyone know where to buy them OR were the same valves used on other models (e.g. W111)??

thanks

Hi mark,
I believe the brass inner part which you require is the same on a W111.
