The engine breather on the FH is much like that on the BSA A10 & A7 and is comprised of a timed vent pushed by the loafer wheel within the timing chest, ported by means of the crankcase joint behind the camshaft area to an outlet forward of the gearbox sprocket. There’s just a little copper pipe which arrived like this:
It’s not presupposed to appear like that. It’s presupposed to be like this:
Within the days earlier than the FERC arrived, this pipe was led to a spot within the alloy arc, solid on the again of the first case to guard the gearbox sprocket, so something coming from the breather lubricated the chain. When the FERC arrived, the breather pipe didn’t change so far as I can inform however as you’ll be able to see it could actually’t get to the gearbox sprocket any extra.
We’ll direct it downwards.
First step is to anneal it by heating it cherry pink and quenching in water:
I desire a bend, simply lower than 90° to direct the gases downwards. I take advantage of the little pipe bender to make a tidy job of that:
I added a little bit of 8 mm gas pipe to a degree fractionally beneath the decrease body rail.
That may do properly.
