[QUOTE="Nightjar, post: 630594, member: 1414"] Flicking through photos from yesteryear and found the makings of our bush camp generator. Bought a Yamaha 3kva for $50.00. It had run out of oil and suffered severe damage. After a search found a crankshaft and big end bearing, new rings and a few other requirements. The alternator was to be bolted directly to end of crankshaft. The taper was 10mm to long and the thread in shaft was 10mm and required 12mm. Machined taper and tapped required thread. Reassembled and has run trouble free at our camp for past 15 years. This year it will have to come home for another overhaul, the timing appears to have slipped and "she's smoking" very badly. Crankshaft destroyed. [img]https://www.prospectingaustralia.com/forum/img/member-images/1414/1641513665_yanmar3kva.jpg[/img] Finished project.
