Flywheel nut questions...

this week i will be putting my new motor in along with a bunch of goodies including a 9.5lb flywheel. First question what size is the flywheel nut? and i was reading through the Hayes manual and read that this the nut needs to be torqued to 280-300 ft lbs and was wondering how do all of you torque it to that?

search!!!

flywheel nut --> 2 1/8th inch

get a peice of flat steel that they sell at lowes or homedepot and drill 2 holes in it that will line up with a couple of the bolt that hold the pressure plate onto the flywheel then you can spin the flywheel until the bar hits something solid and then go at the flywheel nut.

i did search but nothing came up on tightening the nut back to spec. i have a flywheel holder so i don't need to do the bolt method but thanks for the input.

Be prepared-That flywheel holder will not do much good when you start getting to that torque range.

2 1/8, which is basically the same as 54MM. The exact torque spec is not all that important as long as it is close to 300 ft-LBS. I just use a 6 foot breaker bar.

Is there only one way to put on the flywheel nut? Like is it flattened so it should go on way?

Yeah, there is a transmission side and a flywheel side to the nut. You should put the flattened side towards the flywheel.

A breaker bar, two foot long, with a 150 lb person hanging/standing on the end, how many ft/lbs? Yes. Bounce once or twice for extra measure.......or just go out and buy a torque wrench!
