Jinma 204 flywheel question

[RandyS]

Our mechanic has the tractor apart for the new clutch. He needs to know the torque for the flywheel bolts to put it all back together.
5 years old with the 2 cylinder engine.
Thanks.

I'm guessing you have the TY290 engine. I only have the YangDong specs for their older 3 cylinders (approx 37-44 ft-lb) and 4 cylinders (approx 52-59 ft-lb). But I'm thinking it may be safe to use the 3 cylinder spec on yours two cylinder.

Otherwise go by the metric hardness rating stamped on the hex cap, determine the bolt diameter and thread pitch - then refer to the torque chart. I suspect your flywheel bolts are M10x1.25 with an 8.8 hardness rating. The chart recommends ~37 to 41 ft lbs.
