Anyone using a oil thermometer?

[sam2019]

I am looking for one, preferably with a separate sensor with display at the handlebar, but the stick-it-in-the-oil type would also do. There is one on amazon.in but I cant figure if it would fit the oil inlet of the Himalayan.

Some engine temp gauges come with a sensor which fits below the spark plug, and this could probably be fitted to the oil drain plug if they do one for a 14mm plug.
Probably not too accurate but it will indicated something unusual, which is what some might need.

 

[sam2019]

I guess my next question then would be are those holes in the engine standardized, e.g. like spark plugs?
Best of course would be if someone here uses an oil thermo and shares the source ...

Would you consider thermometer that sticks between the fins of the oil cooler? Can also get a different wire for it to go under the spark plug

thanx for the hint but those are available from aliexpress for 1/3 the price but honestly I do not like the design much, I am more looking for a old style round analog instrument. The positioning of the sensor is interesting though. I do not care much for the absolute value it measures but for sudden changes that indicate a faulty or overheating engine, so yes, putting it in the hose connecting to the oil cooler is definitely a possibility.

why do you need an oil thermometer?

to check if the new 462 engine upgrade drives up oil temp.

I used this type of thing once many years ago , found it handy but not handy enough to keep .

question is, will it fit on the Himma?

 

[Shearboy]

I think those are push in ones for Harley oil tanks but there are others made for screwing in on our sort of bikes , someone made one up for old BMW airheads a while back .

Royal Enfield Himalayan 400 Engine Oil Temperature Gauge Thermometer filler cap

threads are M20x1.5mm which is pretty common for oil filler caps. Just make sure that the dip stick doesn't collide with any engine internals.

 

[sam2019]

I ordered a set from banggood that has a seperate instrument to mount near the handlebar and a sensor that somehow will be fitted into the oil drain.
maybe I have to drill out a bolt but thats OK.
those dip stick ones, well I am not going to look at them while driving, and thats a big minus in my book.

thanks.
looks like it replaces the drain plug. hopefully it does

 

[Roy Gavin]

Drain plug is 14mm, the sender is claimed to be 10mm.
14 mm male to 10mm Female adaptors might be around, but probably easier tp find if the sender was 1/4" (1/8 "? ) BSP which they usually are, and which also measure 10mm/ .40"!

I was googleing my heart out for an adapter, but no luck. Finaly we had the 14mm bold drilled and fitted for the 10mm sender thingy. Hopefuly that will work.
I also had to hand-craft a housing for the instrument from an old pipe. kinda overkill but this part will never break

 

[Roy Gavin]

So the sender was threaded 10mm metric, not BSP?
12 mm metric to BSP are easy to find, I have used them to fit oil pressure gauges to my airheads as all the twin senders I could find had a BSP thread.
Getting one with a 45 degree bend so the sender missed the frame tube was a bit harder, if any airhead owners are reading!

To be honest, I dont know, I just took the numbers from that message above. It was done by our restauration expert who can restore anything from any time to factory new.
So it was a safe bet that he could also fit this sensor into the bolt.

we covered it with silicone to avoid humidity - time will tell if thats any useful.



It actually looks quite sharp, I really like it. Clearly it is not VDO or Kienzle but those Instruments would have been well above 100 bucks ....



The housing was welded from an old pipe

And it works, on a 25km run with high and low speeds it went up to 95 C which I think is about right for this engine:
