I use the gun too... Ingersoll/Rand and 600lb/ft does wonders. Never really thought about it too much (for better or worse).

How about 160hp bangin' down a gear or two then wringing it wide open with no clutch at 15krpm??? Just a tad more than an impact wrench, per chance?

Wouldn't it be 56 foot-pounds? Assuming that 160hp was measured at the crank, Q (crankshaft) = HP * 5252 / RPM.

Most impact guns are capable of putting out instantaneous torque in the hundreds of foot-pounds. They also create a transverse stress on the transmission (hence the "impact" part) similar to beating on your countershaft with a hammer as you torque it.

I just try to play it safe when it comes to engine internals, and advise others to do the same. You are probably right. Its not uncommon for me to be wrong.

LOL, it's pretty common for me to be completely wrong. I usually can talk my way out of it though, heh heh.

Erm...YES! I think.

Damn you and your infernal Logic.

That would be true for steady state operation but an impact wrench produces a series of discrete events instead of a continuous torque. The impact wrench equivalent on the motorcycle would be a neutral drop without any clutch usage and the rear wheel strapped so it will not move at all (probably the frame too so you don't flip). The engine has a very large moment of inertia compared to the impact wrench and also has a higher angular velocity. This means the engine has far more angular momentum than the impact wrench and would provide a silly large instantaneous torque when the dogs engage assuming they do not disintegrate.

NERRRRRRRRRRRRRRRRRRRRRRRDS!

It all sounds good to me.

Nuetral and the rear brake with an impact gun shouldn't harm any gears I would think.

Ok I guess I will clarify......................don't use an impact and have the bike in gear.

I've seen with my own eyes someone do it this way and fuck up the tranny. I agree that with a 2x4 between the rin and swing arm and the bike in neutral, it'll be fine.

Next stage of the argument ....

Red Loc-tite or Blue Loc-tite?

I ask because I used blue and it had RED on the threads.

Go by the "number" of loctite. Eg, loctite 243, or etc.

For example these are the "unremovable" loctites:

262 Threadlocker Medium to High Strength
Threadlocker 270 - Maximum Strength Stud Locker
271™ Threadlocker High Strength
272 Threadlocker High Temp./High Strength
277 Threadlocker High Strength
2760 Threadlocker Primerless/High Strength

These are the "removable strength" loctites:

222 Threadlocker Low Strength/Small Screw
242® Threadlocker Medium Strength
243 Threadlocker Oil Resistant/Medium Strength
246 Threadlocker High Temp./Medium Strength
266 Threadlocker High Temp./High Strength
294 Threadlocker High Temp, Wicking Grade
2432 Low Halogen, Low Sulfur
2440 Threadlocker Primerless/Medium Strength

I personally have a bottle of Loctite 243, and loctite 222. I use 243 on engine bolts and nuts I don't want coming off (like my countershaft nuts). I use 222 on exterior parts that I don't want rattling off. The 222 strenth is almost like the assembly paste they put on from the factory. (That *snap* you hear when you loosen a bolt off for the first time).


Don't even get me started on their aneorobic sealant line... (I use 515).
