oil pan temp sensor

[zookrick]

I want to put a temp sensor in my oil pan sump plug.

I need to find a source for a 1/8 npt to 14x1.25mm ( sump plug thread?) adapter.

I have looked and googled all over and cant find one. Anyone know of a source for the adapter?

Speak to Jon at digital speedos, he does temp guages and senders  that fit into sump plugs. I have one fitted to my bike

[Bigkenxx]

Also on flea bay sump plug adapter send a message for your size of thread external and internal

Ive just made one, you need bspt (taperd tap) and I used Peugeot m14 1.25 sump plug, £3. Winner so just drill it out and tap it. Sorted

BSPT and NPT don't match up exactly, NPT taps fairly easy to find though

If I could make one I would. But I dont think I can with a handrill and a vice.

I found an adapter made out of aluminum, but  I am not sure putting an alu plug in an alu pan is a good idea. Might vibrate loose??

[jameskat]

If you are worried about vibration the stick some thread lock or hydraulic seal on it, Aluminium plug and pan will expand at similar rates and is also a better thermal conductor.

Yup, something like loctite 577 will do the job. Good for up to 150degC, should be enough?

[zookrick]

I installed the sensor yesterday. I thought of using loctite, but with all the oil on the threads I didnt think it would do any good. Being able to use a torque wrench on it would ease my mind but not possible with the sensor sticking out.

Really nice to be able to see what temp the engine is running at. I wired in some fans on the cooler so when I get stuck in traffic I can turn them on and cool it down and not barbeque my oil.

What temperature sender are you using? 

[zookrick]

The sensor kit is a Koso brand

What about going in here

[zookrick]

On my bike they are not accesible there are frame rails right next to it.

Thats where I wanted to install it in the first place.

What's the thread size there? 

[Solcambs]

The Japanese Yoshi site has the threads sizes listed for the recommended point for temp senders for their gauge.  IIRC it was a Type A sensor which was M14 1.25mm from memory (this was used for a sump plug on the later models). I think the  Type A is used on the earlier models in one of the side points ..

Hang on a sec .... here you go!

If you notice temp getting high are you going park it on side of the road. Ive always wondered why bother with high compression motors as soon as you stop they hot so have plan journeys carefully. If you tune need add extra coolers plenty of documentation from back in the day.

Ive ridden italy back with high tuned motor you can feel it straight away as it gets hot, just gotta turn it off.

Not knocking you just made me think of sols worrying.

The problem for me is traffic jams in the summer that you have to go through to get anywhere decent. I was in a bit of one a couple days ago, the temp gauge showed 110C I turned on my cooling fans and it never got any hotter than that.

How hot oil temp is too hot so that the oil cooks itself and breaks down?

[Gixer1460]

Oil at 150 degrees ain't good long term but upwards of 250-300 degrees is needed to ' cook it'. More likely to seize before then!

110 with Fan that is interesting but adding fan adds weight to bike thats bad.
