Torquing Flywheel / Motor Turning

[Mack90]

I looked at the manual and 200 to 220ft/lb was the spec. I cannot get it torqued down without the motor starting to turn. Do any of you have a tip on how to keep motor from turning while torquing bolts?

On my old V8 pickup engines I used to put a breaker bar on the crank pulley bolt to resist turning. Maybe doing the same on the accessory drive nut would work?

See if you can wedge a block of wood in there.

I imagine the "proper" way to do it is to use the Cummins tool that inserts into the block's access hole to manually engage the flywheel with a gear on one side and a square indent on the other and then put a breaker bar in that tool.

I m going to try a wood wedge first and the breaker bar on front if engine. I hope I don't need the special tool. Great ideas and thank you all for the input!

Just use some longer 3/8" bolts and put them in the place your pressure plate bolts go in. Use a pry bar to take the tension when you go to torque the flywheel.

Personally I just hit em with a Milwaukee half inch gun and roll on

I will go that route. It sounds like I am being overly cautious.
