I think you might have overfilled it Mike.
I have produced some notes offering corrections to those in the technical section.
Though they are generally correct in theory.
I think there issues with the size of the paws, but I want to address that with mine before I commit to paper.
Although the idea was to keep dirt out, this may slow down your weeping.
Mike, unlike the Burman and Albion boxes, the M20 box should NOT be run with grease. There are small drillings and oilway in an M20 box that require lubrication with engine oil only. Regards Ron
Thanks for the update Ron, I had it in the back of my mind that I couldn't use liquid grease in the M20 box but couldn't recall why! Mark, it may be that I have a little too much oil in the box though in the thread 'Gearbox oil overserviced' Ians advice is to fill part way up the filler neck, half is I suppose part way but far from the 'Keep full' as written on the filler plug. Your adapted bush may well do the job. I'll have to take the end cover off and measure it .
Many thanks
