Anyone got a torque wrench I can borrow?

As the title states really, need a 450nm+ torque wrench for the crank bolt on my 7A, trying to call in a few favours but coming up short.
Cheers

Not sure but I don't think they exist think I did mine to 200 then turned another 180 deg something like that, or I might be imagining the whole thing

Torque wrench

They do exist in the motor industry do you know anyone who works on HGV,or bus industry they have them for tightening wheel nuts up to 350- 400 lbs ft.Derek

I know of a few people in heavier engineering than myself just can't get hold of the ******s, there's a tractor dealership up the road from Home that I may be able to hire one from cheaper than a hire company who want ~£25 a week but I only need it for one bolt so don't really want to do that.

I have one but am in Hampshire.

Postage will be around £10 each way its almost 6ft

just go 200NM + 180 degrees. You need a 3/4 drive bar and socket though, 1/2 no good here

200nm+180 degrees seems to work fine.

You can get a used Norbar 5R 300-1000nm on ebay for about £100.

Well in that case that's what I'll do, I know someone who has a 250ft lb on which should do the trick Thats for the offer Chef, and thanks yet again for your help chaps

maybe this will help if you can't get a bigger wrench :... wisdom from a chap on Motorgeek as to how to use a big breaker bar and calculate weight/length/torque :

One solution to the torque question is good old-fashioned math and physics! Remember foot-pounds are just that: x pounds of force applied y feet from the center of rotation.

So if you weigh 150 lbs, and apply your body weight at the very end of a 2-foot breaker bar, the torque you get is (150 * 2) or 300 foot-pounds. 200 lbs. at 18" (1.5 feet) would yield the same torque.
