Hi, (very old thread but...) as I am going to mount a temperature gauge and sensor for the finaldrive I have found these part numbers from VDO to suit this purpose:
Temperature gauge International 20-100 °C
Part.nr.:310 030 022
Temperature sensor 120°C M14x1,5
Part.nr.:323 801 001 006
If you need the gauge reading °F I am sure you will find it by searching the above part.nr.
do you have any more experiences about "normal condition temperature readings" of the FD? Any other good info about this "farkle"?
just making sure the picture you posted of the sensor is way too long but I guess that is just showing a general picture of the sensor principle, right?
I have run the bike with Red Line Heavy gear oil in the FD and it seems to run slightly cooler than with the regular gear oil. I run it with Red Line through two oil changes (2 x 10000 km) and the third leg I use regular 80-90 W "BMW approved" gear oil.
I have a spare FD in the garage and change the whole unit every 60.000 km without any further inspections or analysis. Then during the winter I pull the main bearing out, check the shimming and leave it wait on my shelf.
BTW, why don't you take your time and visit our 9th annual BMWKLTIBMIKOF-meeting and take some of friends along!
We have had many nationalities (Swiss, Austrian, Italian, German, Norwegian, Lithuanian, Australian, Belgian, Latvian, American, British etc.) visiting us over the years but so far no Swedes!
There you would see some "farkelized" LT:s, GTL:s etc. We still have no mandatory inspection (TÜV or similar) like many countries have...;-)
Vi även talar svenska!
