I've got a grab bag motor coming from thatsdax that I plan to use as an "educational tool", in other words I plan to take it completely apart and see how our Chinese brothers get these little motors to do what they do! I felt like a torque wrench was justified so I got one.

This naturally lead to HOW MUCH? Newton meters, inch pounds, foot pounds, Kg, cm holy crap! Found some conversion tables to make the water even muddier, for instance I want to tighten something 10 Newton meters--
1 Nm = 8.8507 inch pounds X 10 = 88 1/2 inch pounds
1 Nm = 0.73756 foot pounds X 10 = 7 1/3 foot pounds
Now I know 12 inch pounds = 1 foot pound, so the numbers above just don't look right. I confused maybe it's too early for numbers, yeah thats it! Happy Trails Walter F.

Sorry, I gave up math after kindergarden, I was burned out on it by then.

8mm 15 ft. lbs.
6mm 12 ft. lbs.
Spark plug 8-12 ft. lbs.
Everything else, hold the screwdriver as tight as you can and don't bugger up the slots.

Sometimes you just need a bigger hammer toorotfl
LOL, snork. It is a joke in my house. I fix a great many things on my MBs with a hammer or mallet. I call it "the large frame adapter"

For torque on a Chinagirl MB, I use 12 LBS on every thing. Engine, mounts, sprockets etc, every thing. I am sure this is wrong but works4me. I have never broke any thing, but had to go back and pick up a motor after it fell off.

(Sears has a good torque wrench for $20 something. It is to long handled, but great.)

Snork, snork GH. (persuade the bajeebers out of it!)

I really did buy a rubber mallet just for frame "readjustment" Works. Got a chinagurl on my Point Beach with out an adapter.

Goat Herder, I always wanted to ask you but was too sober to ask. How did you come up with your nick? There is a thread some where, but I forget.

Walter your math is close enough. Only the head is critical and its not really critical. Most important is that the bolts are even and not way over/under torqued +/- a foot/lb won't make a difference as long as they're even. Proper torque for size of bolt is good everywhere else.

Been doin' more research and it seems there is a "dry" and a "lubricated" number, the lubricated number being lower. I use anti-seize on all my bolts, so I guess mine are lubricated??? I guess I need to drill and tap a piece of aluminum and strip some threads or twist off some bolt heads. This torque stuff is more complicated the deeper I look, but I'm in it to learn, so I''l dig a little deeper. Happy Trails Walter F.

The coyote verses the sheep dog, they had a time clock with punch cards. When they were off the clock they got along , when punch back in they fought like [email protected]@. If ya seen it you would dearly love the sarcasm! on another note where is larkins, he could sure dig up some edjumication, he's alright by me. I did sorta give up on some of my math though. Snork! Although for reading between the lines somtimes me eyes did glaze over some still woudn't change much need you here ma boy take care:rolleyes:(^)

Its a darn thing from missing what the true conversation was I see here some hoopla about tork specs I 'am a certifiable ralph certified mechanic I truly missed somthing. Apoligeies for wrong , I can say a torch wrench is one of my best freinds. Mister Larkins GOD BLESS YOU you hold our youth, and I'll will probly continue to misspell words. Fight the good fight!!!!!!!

Wasn't really a question, I had a bunch of numbers in my head trying to sort out converting Newton meters to inch pound or foot pounds of torque and needed a math teacher to "talk me down" from my number induced tailspin, then everybody changed the subject from torque to compression and the proper application of a hammer in construction. Happy Trails anyway Walter F.

Never sieze is lubrication.
You don't need to get too crazy about exacting torque reading on these bike engines.
The aluminum you strip out will likely take more torque to strip than the "anti-metal" these things are made of.

So I go with the lower lubricated number eh. I'm just trying to get some standard numbers to use all the time that I can remember a base-line if you will your Visionaryness. Thanks for the help!! Happy Trails Walter F.
