Thanks Kev for the reply and links.
im ok with getting the parts as I have a couple of trade accounts around, more interested if anybody has done one and has any pearls of wisdom they could share.
I will definitely change the gearbox oil, maybe spigot bearing as well - I’m presuming it has one!
I’ll be on my back under it with a trolley jack, as lm too old now to ‘treat it like a bench press and drop it onto my chest’ method!
