torque engine cylinder head bolts "yanmar 1610dt"

srca · Jan 31, 2015

Hello, I have burned the head gasket engine of a yanmar 1610 dt (3T75U-NB model) and once I have the spare, I need the torque of the screws of the head gasket.

Screws in question are:
- 8 screws (hardness 10 M12 x 83mm)
- 3 screws (unknown hardness, M8 x 85mm)

I also need the timing of the intake and exhaust valves.

thanks and regards

No pdf. What language do you speak? The closest English manual to your 1610 in probably going to be for the ym220/226.
