I need some help, I want to add a custom pulley to the front power take off (crankshaft pulley) on our yanmar 3QM30 and do a custom alternator mount. I've measured the crankshaft pulley, but I'd like to make sure my dimensions are good before I have a custom pulley made $$$. The infos I need are in the Factory Service Manual. I've found the pictures of the pages I need on Boatdiesel.com, they are attached below. If someone could post the full size pages it would be very appreciated. (Just for fun, my measurement so far are a bolt circle of dia 150mm and the spigot needs to have a dia of 95mm...)

I have what you want, but don't have time to scan them now and send them to you. Maybe I can find the time tomorrow. Or you can send me a message and I can email them to you.
Thankyou very much Jose, this is very appreciated and very helpfull, I though the engine was all metric, but it appears it has been design in imperial with metric fasteners and that was something I was afraid of.
Well, I just got done scanning all the pages, but I guess you don't need them now.....so I won't bother attaching them.
Re: 3QM30 Service Manual
It would be a really good resource to have the manual on line (I have a hard copy as well). I would certainly be willing to scan 20 or 30 pages for a good cause. There may be copyright issues though I can't imagine Yanmar has too much interest in these old engines. I guess Phill would have to give his blessing as far as HOW is concerned...maybe there is somewhere else we could park a copy?
Anyway, since Bill has already done his piece, myself and others would have to step up to the plate. How about it folks - 30 pages each? (or a chapter or section or whatever makes sense)

Thanks again Jose for the PDF, it's already printed... I will post detail drawings of the custom sheave I'm designing to put on the front pto.
The manuals are still for sale as well for anyone who wants an original hard copy, I don't think the chandlery on this site competes in this space:
