Yanmar 2GM20 Workshop Manual/Torques

[G12]

Hi guys,

I am unable to find a copy of the full workshop manual for the 2GM20 despite many sites seeming to offer it (lots of dodgy looking download sites). I'm after the torques for the bolts holding the drive plate to the flywheel and the bolts holding the gearbox to the back of the engine. I could just do them up of course but I like to get things right.
If anyone could either point me in the direction of the full workshop manual or just tell me what the torques are then that'd be great!

Thanks

Good morning G12, I tried to include a service manual here but it 14.6mb it's too large for this server however I see the U.S. j30 class website has a good workshop manual for these engines which is worth a look and might be download-able. They have some other very useful notes for winterisation etc which I referred to when I had a 2GM20.
good luck.

Tiggy, that's perfect, thanks very much. I know it's out there in all sorts of places but google seems to ignore them.

That was my first experiment with that in Dropbox just now.

Well it bailed me out, thanks. I like to know things are torqued correctly.

Hi G12, I found this comprehensive manual for the 2GM20 and 30.
