I'm after some torque settings for the following bike can anyone help?

Suzuki DR250 XC Djebel 1997 (SJ45A)

Specifically I am looking for:

Front axle
Front axle pinch bolts
Rear axle
Rear sprocket bolts
Front brake disk screws/bolts
Front brake calliper bolts
Front brake hose banjo bolts
Sump bolt

Thanks,
Patrick

Also, if there are any traps to using a torque wrench that would be useful. I just picked up a 1/2" wrench from Super Cheap Auto for $40 plus a 1/2" to 3/8" adapter for my existing socket set (at $6). Doesn't seem to bad to me. Hopefully it will last.

Just out of curiosity, what is the torque wrench range?

It's listed as 10-150 ft-lbs. I have absolutely no concept of how much rotational force 10 ft-lbs is so I am hoping that it isn't too big. (It certainly has a big handle.) If not, they didn't seem to have a problem with me bringing it back and swapping it for a 3/8" one (which they didn't have in stock in Albany).

You should be sweet. Pinch bolts are probably the lightest item there and should be around 15ft-lbs.

Front axle 47
Front axle pinch bolts 8.5
Rear axle 79.5
Rear sprocket bolts 16.5
Front brake disk screws/bolts 6 (with loctite)
Front brake calliper bolts 19
Front brake hose banjo bolts 16.5
Sump bolt 15

(According to Mr Suzuki).

Thanks I appreciate that. I guess I will just go with 10 lb-ftbs for anything that is small as that is the minimum on the wrench. The mechanics I spoke to just said do them up tight you only need to torque stuff in the engine. I'm not sure I agree with that, but I'm hoping that torquing a bolt down to 10 ft-lbs when I should be 6 won't cause any undue problems.

Ummm. YES IT WILL!!

10 Ft lbs is almost TWICE the torque that is required for that bolt....

There is a chance you can stretch the threads... OR tear away at the threads in the soft casing.... Depending on application of the bolt.
In your case, you could be up for a new brake caliper....

Rule of thumb is to get the correct spanner that fits and put an appropriate amount of weight on it.
This will be close to a trained hand.

For 6 ftlbs, you should actually be using 72 inch pounds... on a 3/8 drive (or smaller wrench).

Torque wrenches should always be selected so that the applied torque is in the middle third of the wrenches range....

So for yours best torques are 50 to 100 ftlbs....

Hope this helps.
