Hi Chris

They are commensurate with similar fastenings on my T160 minus a little for material development.

Regards Mick

I did my crankshaft nuts up with a quick blast from my Milwaukee cordless Rattle-Gun (its a serious tool).

New lock washers and so on of course.

Time will tell 8-) .

Hi

I'm assuming your impact driver ratings are in pounds force inches, (divide by 12 to get pounds force feet). Personally I wouldn't use an impact driver to torque fasteners, but if you do I'd advise only letting it 'rattle' three or four times on each fastener.

Regards Mick

I just gave it a quick 'Brrrrrrrpt' - nothing sustained. The Milwaukee has removed rusty bolts from my Toyota Landcruiser that I couldn't shift with heat and a 24" Power Bar (on my back, bracing my feet against the chassis). I treat it (and the nuts) with respect (six-point impact socket of course).

they are Milwakee 1/2" drive the big one done the hub nut on a car up so tight it done the new wheel bearing in i let it rattle three times i think the big one would strip the half nuts i got to make a long socket for the gearbox sprocket i think its 1 1/4" b s w or 1 11/16" AF

I think Johnny is talking about impact wrenches not impact drivers. I bought a cheap one recently that is rated at 350 ftlbs not inlbs.

I wouldn't put an impact gun anywhere near either of those applications as you don't have anything substantial to oppose the shock forces and may easily chip a keyway or something .All those splines, mainshafts etc are hardened. IF the sprocket is not a tight fit on the spline it's likely to move anyhow and the thin walled spacer you are pulling it up on doesn't provide much area . Some gearbox sprockets (modern stuff Honda's etc) are only held on by a circlip which inevitably results in wear over time of the spline and the sprocket. The Tab washers are very necessary in these places. The six small HARDENED bolts holding the clutch basket to the BIG sprocket are one of the most critical of all the fasteners on the bike IF they have run loose for any time they ovalise both the treaded bits of the big sprocket and the clutch basket holes, requiring repair of the basket and a new sprocket. The 6 bolts need to be made of Bl**dy good stuff and tightened well. Nev
