M20 Oil Drain Plug Tightening Torque

[der_Thomas]

Hello,

I just replaced the old steel drain plug by a new alloy adapter screw for an oil temp sensor on my Bellagio.
Then I was searching for the tightening torque but neither in the Bellagio repair instruction nor in the Califolnia 1100 repair instruction I can find it.
In the bellagio repair instruction Guzzi only is writing about an M10-screw, but that doesn't help much with the M20-screw... :|

Do you have any idea about the rightening torque for M20 oil drain plug?

Otherwise I have to rely on my feelings :unsure:

Best wishes,
Thomas

So you have an alliminium plug, 10 mm male for the sump and 20 mm female on the other end for the oil temp sensor to fit into? It so then you will need to hold the adaptor while tightening the oil temp sensor or you will over tighten and shear off the 10mm part. I would use new washers and tighten the 10mm to 12 Nm (shop manual info) and the 20mm to about 18Nm(my guess).
But maybe Im thinking of the wrong set up you have./
Cheers

Hahaha, no :lol:

Bellagio in fact has a M20 oil drain plug but in the repair manual Guzzi is giving the tightening torque for a M10 plug.
I think, this is a mistake from Guzzi because all other actuall sold guzzis have a M10 Plug.

Then I took a look in the 2003 California 1100 manual but there Guzzi completely forgot information about tightening torque.

The information about the adapter screw only was a marginal note, the adapter screw of course is M20 also.

Greetings,
Thomas

That error in the service manuals has been carried along as far as 2013. In the service manual for the 2013 V7 Stone, there is a pointer to the M10 plug and a specified torque of 40 Nm! However, elsewhere in the service book, as well as in the owner's manual, there is a specified torque of 12 Nm for both the M10 and the M20 drain plugs. Still no specified torque for the oil filter retainer bolt, however. Anyone have more info?
