hi,

I am looking for the correct torque values for these drain plugs. They are on a strada 750 which has a very similar looking engine to its 650 and 350cc brothers. Does anyone have the correct values. The plugs are M10 with aluminium washers going into alloy of course.

Cheers
 
It isn't high, and I've never seen the torque published in any manual. I do them by feel. I've seen the threads stripped out of the cases when folks get carried away. They just need to be snug enough for the sealing washer to do it's job and not have the plug back out on their own.
 
Like John said. Put them in finger tight then just snug a bit.

If you are worried about over tightening them use a 1/4 inch drive with a socket instead of a box wrench, you won't get as much leverage with the 1/4 drive so you have less chance of over torque.

For me it is better to "keep an eye" on it & re-tighten than to deal with stripped threads.

I have a brother I call "little more" , "extra turn", or "stripped thread".
 
Yes John & Trout, are exactly right !
Unfortunately, these days, due to lawsuits for the most incredible things, fabricators get very scientific, to protect themselves.
Do not use this stepladder, in mud ! Etc ...
Use a standard ring or open 6 to 8 inch long , spanner, tighten the drain plugs by hand, then using the spanner, do a slight turn.
For simple stuff like that, a torque wrench is not worth bothering with.

Obviously, use a new aluminium washer, each time.

If that causes drips, then get the appropiate spanner out, and tweak it, a bit more !

You will get there in the end !
 
I've starting using this part 01528930 for all 10mm plugs. It has a rubber insert that seals very well and can be re-used many times. I'm sure it is available commercially, but it is very easy to just order from a dealer. Besides, ordering parts from dealers helps to keep their doors open.
 
I like the rubber insert plugs also. I think the rubber may help a bit with vibration so they don't loosen up.
 
John .... That is a good post !
But .... All suppliers, have their own numbers, for parts !
Could you please .... post a photo of the Item , plus the address you ordered from ?
Cheers !
