Default Anybody seen Mr. Larkins?

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.

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.
