carby linkage pivot pin H8

bob ward

This is a photo of the manifold on a 35 H8. The pivot pin sticking out of the side of the manifold is badly worn and Plan A is to remove it and replace it. 

I'm assuming, but not certain, that the pin is threaded into the manifold. I've tried gently to turn it with a stud extractor without success. Before I get too gung ho about it, can anyone say if the pin is threaded?

Plan B is a thin walled sleeve siliconed/epoxied to the pin.

 Bob, I think I would try  "plan B".. I suppose that is only used on RH drive cars?

There's one on this '36 engine, but it looks to be larger diameter.

G'day Dave. I'm not an authority, but I'm quite certain that the carby linkages are the same for LHD and RHD at this point. The photo shows the pivot point with the linkage mounted. 

If I can unscrew the pivot from the manifold that will be ideal. If the pivot has been cast in or pressed in, Plan B it shall be.

 Bob, it is a threaded stud.   Try banging on the end of it a few times with a hammer, and then use vice-grips. back and forth continuously and it should break free.  Keep back-and-forth in greater arc each time until it eventually turns right around, and then you can unscrew it.

 Is that a master cylinder I see tucked away under there????

That is a master cylinder Geoff. According to my research, in preparation for the introduction of hydraulic brakes in 1936, Hudson did some prototyping on RHD 35s for the export market.

They got the 36 master cylinder, 36 5 stud wheels, and 11" stepdown drums.

Yeah right!  Pull the other one!
