I recently removed my flywheel to get it resurfaced and now that I'm trying to put everything back together I'm trying to figure out a way to torque it down to 350, I've found a couple posts just saying f it and use a whole bunch of extensions to get it close enough. I also found one post by nycgps from 2012 giving instructions on an angle torque (I'll post the screenshot) but is that really the way to go? Or do I need the actual torque wrench. I appreciate any advice. Post from 2012
Nycgps's suggestion seems the way to go if you don't have a torque wrench that can do that much force. It should appoximate 350lbs and with some blue loctite should be good to go. Using an extension on a torque wrench I wouldn't advise unless you want to buy a new torque wrench.
Hm okay but wouldn't the torque wrench just click at 60 foot pounds anyway? Any amount of leverage wont effect how much force the torque wrench "feels"?
The issue with a torque wrench is that it measures how much torque has been applied to a fastener, not how much torque has been applied to the handle.
If you put a 6' pipe on a torque wrench set for 60 lb.ft it will still only click at 60 lb.ft on the fastener. You'll have to use far less force at the end of that pipe to get 60 lb.ft but still only 60 lb.ft.

This method omits the use of a torque wrench...in lieu of math and physics.
Use a 6-pt socket, a breaker bar, w/ the 6' extension over that.
Start by tightening the nut using the breaker bar only. Add the 6' extension, and smoothly continue tightening ...being sure to place force at the end of the extension bar. W/ respect to estimating 60 lbs. I regularly lift and have no problem estimating 60 or more lbs of force. However, if you're unsure... tighten the nut to what you believe equals or exceeds 60 lbs., then position the extension horizontally, and place or hang a known force of 60+lbs on the end, e.g. a good deal of your body weight . (Note: Be sure to have someone secure the socket on the nut while doing this) If/when the bar does NOT move using this test...you've achieved >=60lbs. Therefore, 60+ lbs x 6ft = 360+ lbft.

Alternately, if you weigh 180 lbs, you can use a 2' pipe and find a safe way to put all your weight on the end of the pipe.
Or put a bathroom scale next to the end of a 6' pipe and stand on it while pushing down on the end of the pipe. When your weight on the scale registers as 60 lb less than actual, you've applied 360 lb.ft to the fastener.
