Starter Clutch Failure

Draw a force diagram showing the applied torques. 

Maybe you can do that, but I contend you will not put discrete perpendicular force as modeled by such a diagram...  I do agree that is the extension is shorter than about 1/4 of the torque wrench length, the difference will be negligible.  Imagine a 1 foot torque wrench and a 10 foot extension however, and the diagram will not reflect how you actually turn the bolt...

Frank - if you have one of the older style torque wrenches that had the "pivoted" handle for lack of a better term, it would be much easier to keep a true perpendicular pull on the torque wrench without adding a lateral component.

Does anyone have a GYSM that shows the torque for all of the engine mount bolts and the lower frame rails? The Haynes manual does not list specific torque figures. This is for the 1991 and later rubber engine mounts and the single upper rear engine mount.


Thanks

Fred, a bloke with your experience shouldn't need to torque any of those bolts.
However, in the absence of actual values, I  believe there is a general guide to torque settings by bolt size in the front of the manual.

I have the factory manual in pdf if you want a copy let me know

The lower frames rails and engine mounts torqued. Slowly getting the rest together. Closed up the engine and filled with 4 Liters of break-in oil.

The engine passed it's first test. Using the starter, I spun the engine long enough to prime the head with oil. Every stab of the start button gave an immediate engine engagement. No abnormal sounds and strong puffs of air out of the spark plug holes.  

This may be road ready by the end of the Weekend.

Playing with my camera filters. I did a few in Black and White.

Back to the torque wrench adaptor.  The torque along the wrench is constant over the length of the adaptor wrench. 

If you were to push or pull along the axis of the torque wrench, then the length of the adaptor wrench would matter.

I think I've got this.......... looking at the way the force is applied to the torque wrench handle, with the extension in place, the rotational force applied to the end of the wrench is not perpendicular to the line directly from the nut - and its perpendicular component is therefore less than if the force was applied to the end to the torque wrench when it's attached directly to the nut/bolt. That lower perpendicular component is however, applied slightly further away from the nut/bolt.

That reduction in perpendicular force is proportional to increase in distance of the application of the force, from the nut/bolt - so the torque (force x distance) applied by either method is the same (it will just take less effort at the handle to achieve the same twisting force at the nut, with the extension being used).

ADDING AN ADAPTER TO A TORQUE WRENCH


(TA x L) / (L + A)  = TW

Length (L) = length of the wrench
Dial Wrenches = The measured distance from the center of the square drive to the center ring or notch on the handle.
Micrometer Wrenches = The measured length from the center of the square drive to the center of the handle, with the wrench set at the desired torque reading.
Desired Torque (TA) = The torque value designated for the fastener with or without an adapter.
Added Length of Adapter (A) = The measured length from the center of the adapter drive to the center of the wrench square drive.
New Setting (TW) = The torque setting on the wrench allowing for the added length of the adapter. This reading will be lower than the desired torque.


Example:
250 ft. lb. Dial Wrench using a 2" long adapter

L = Effective Length: 18.75"
Desired Torque = 250 ft. lb.
Length of Adapter = 2"
Result:
18.75" x 250 ft. lb.
18.75" + 2"
= Pull Wrench to 226 ft. lb.

Well done - biting my nails waiting to hear how it's going

Finished prepping the bike, carbs and exhaust. Installed the new RPM logo UNI filters. I don't know how long ago UNI changed from Red foam to Black foam. The UNI filters that I removed were the Red ones and the outer layer was beginning to breakdown. Primed the carbs and the old FJ fired right off.
