STIHL flywheel nut tightening

[old-cat]

MS360, the service manual says 33nm which equals 24 ft. lbs. approx. When I try to get it this tight with my 1/2" torque wrench, it feels like I'm pushing it into the spongy zone.

Feedback please.

Forget the torque! Just crank it till it feels about right

A 3/8" sq drive torque wrench is much more accurate at 24 ft lbs. I have seen 1/2" sq drive torque wrenches off by 20+ lbs at lower settings , below 50lbs.

A half turn before it breaks is close enough. :msp_smile:

Good enough. Thanks:msp_smile:

My snap on 1/2" tq wrench is off by 15ft/lb at 200 setting so low setting is probably off a bit too. My snap on dealer has a tq wrench tester on his truck and all snap on tq wrenches test high even after calibration. I snuck my mac tq wrench on the snap on truck and it tested dead on. That made the snap on man stutter.
I would also use a 3/8 drive as they are much more accurate at lower tq

So you have a bunch of crappy rope stuffed into the cylinder???

I always tighten nuts up to the point that they strip.....then I back it off 1/2 turn. :msp_wink:

Dewalt 1/4" impact until makes the impact noise, whatever you call that a few times. Never had a problem and you don't need anything in the cylinder. Let the flaming begin.

My piston is off and I have two blocks of wood under the wrist pin:cool2:

1/2 turn before it breaks, sounds BETTER :jester:

I do the same except, instead of backing off, give it an extra 1/2 righty tighty

I take the flywheel and clutch off first before taking the cylinder off

Wow!!!!!!!!

Why on earth would you do that??

When you use an impact wrench that sequence isn't necessary

 

[H 2 H]

Are you having problems getting it off ?

 

[old-cat]

Thanks to the previous replies, my problem of tightening it back on are solved. I just took my 3/8" breaker bar with 1/2" socket and made it feel right.
