Thinking about wrenching the crank nut to line the arrow.dot up with 12 o'clock when "6 is at TDC in order to adjust the "5 exhaust RR.

Is this hard to do?

Thanks.

 

Normally it's not a problem as long as you take it slow as compression bleeds off. That way, you won't have to crank so hard and put excess pressure on the bolt.

 

I'm not sure if I'm understanding you correctly, but if you're talking about rotating the crank via the crank nut, to turn the engine to #6 TDC, then no it's not hard to do. Just be sure to turn the crank clockwise, otherwise you'll end up loosening the nut, lol.

 

Thanks much.
