Hi, are the pushrod tubes for the model G, push in or threaded into the head.cheers.

Push in they can turn freely make sure to seal them in the head .....Chris

[Michael Will]

Thanks Chris.

I seem to remember that Merv Kendall had overhauled a few G engines and said that he'd seen both types. Possibly they changed during the production year so keep an open mind about this.

Thanks Dave, I have ordered a set of push in tubes from Pat the forgeman.

Yes I've seen both types. my 1930 has the threaded ends. I don't know how the others stay in place, unless they rely on the fit. Nev

The head of my motor came away freely, I assumed they were pushed in and put the head on again, I should have checked but was more interested in the state of the bore.

Clearly that type does rely on the fit. The lower ends are slightly reduced in diameter for a small distance.. You would have to align them to the holes in the aluminium sheet cover as they are a "reasonable" fit. The original breather (oiler??) is clearly in view there. It lets stuff in, not out. (as I see it). Nev

Thank you Nev, I may end up using the old ones after a clean up in some evapo-rust.
