Final drive oil temp gauge

Here is a picture gallery of my final drive oil temperature monitoring system.

http://picasaweb.google.com/pozoizqu...VEOILTEMPGAUGE

At first I was using a regular VDO oil temperature gauge with a range of 50 - 150 deg C ( 122 - 300 deg F) but it was wrong range ( too high). The new gauge is actually labelled for hydraulic oil temp metering ( 20 - 100 C / 68 - 212 F) and with the properly calibratated VDO sensor I now get a quite accurate reading of my rear drive oil temperature.

I want to emphasize that I am not paranoid about my final drive. I have had no failures so far but I had the main bearing changed at 63.000 km last year together with my (self broken) gear box. I just happened to have locations for three extra gauges and oil temperature gauges (both engine and final drive) are quite easy to install. So now I can watch my engine oil temp go quite fast up to 73 deg C ( 163 F) while the final drive oil takes much longer to climb up to 53 deg C ( 127 F). This takes about 40 minutes on an autobahn at 140 km/h. And on rainy weather the temperature goes down dramatically ( 15 - 20 deg C) because of the cooling effect of the evaporating water on the drive housing.

So if my final drive temperature ever starts to raise to 60 deg C ( 140 F) and above I might start wondering what is going on...

Nicely done. I have a new direction in life- I will strive to place at least 10%
of your farkles on my LT.

Ari any VDO part numbers that you can post so we can avoid the confussion you incountered? Another great Idea......

Re: Final drive oil temp gauge

Ari... my wife just asked.. "How much MORE does that bike weigh with all that k..., "stuff" on it???"

Yeah, I know, she doesn't understand.... but that's part of what I love about her... and she just smiles that I like this stuff too.

Great idea .... But bummer for our LT .... out of room for instruments, farkle overload at present.

Craig, sorry I don't have the VDO part numbers available but the critical dimensions of the correct sensor are: Thread: 14 mm, length of the sensor with thread included: 15 mm. The sensor has a code "907" stamped on it but I don't think it is the part number. The "wrong" sensor that I had originally was 40 mm long and that was way too long.
And as I said, the optimal gauge has the range from 20 - 100 C or 60 - 212 F.

Channing, you can tell your wife that my bike weighs about 20 kg more than stock with all the kitch eh...farkles. This was proved when both mine and my CCR buddy Jouko's bikes were weighed just before the air freight from Toronto to Frankfurt two years ago. Mine was 445 kg and Jouko's bike was 424 kg. Of course we both had the cases full of riding gear and other stuff that we did not carry with us on the flight.

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.

@pozo_izquierdo do you have any more experiences about "normal condition temperature readings" of the FD? Any other good info about this "farkle"?

Hej Mats,

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!
https://sites.google.com/a/bmwkltibmixof.com/english/
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!

+1.

Many of us Finns try to copy (some part) of Ari's inventions...

Born to be wild so why not

Hi Ari,
Yes you are right about the picture. The product.no. given here have a length of 15mm just as you mention in the thread.

Regarding the BMWKLTIBMIKOF-meeting; Seppo already invited me
By the dates for the meeting me and my wife will be riding the bike in Croatia. Hopefully next year? ThanX anyway for your invitation.

Regards,

Mats

I checked this again and unfortunately I gave the wrong article#. The correct number is 323-801-012-002

Attached you will find the catalogue (page 31) where I found it.

Sorry for any inconvenience.
