Push Rods for OHV F/G31

[alexd912]

HI all,

Does anyone happen to have a drawing of the pushrods that are used on the F/G31 OHV engines?

I would like to check mine as they seem to be slightly different lengths.

Regards

Alex,

My 1934 OW1 push rods are 7-7/16 between the centers of the spherical surfaces. I reckon they are the same push rods as use by the F/G31-32 models. The caps are simply soft soldered onto the tubing, and I doubt that the factory observed a high level of precision on the length since there is quite a range of adjustment with the tappet adjuster screw. Having said that, depending on how the tubing was cut to length and the caps machined, there should be some constancy in production. I would expect them all to be within a sixteenth, but in reality they only need to be within a 1/8 of an inch and they would still work.

Hi Doug,

Cheers for this and I will check the lengths but from memory there was a lot more difference that that.. After looking at the rockers on the other engine im starting to think that they are slightly different but I wont know till I compare them side by side.

Thanks again.

Oops looks like I posted this in the totally wrong discussion thread. Could a moderator move this to general discussions.

Thanks
