Thread size of oil sending unit

[Mahindra35]

Anyone know the thread size used on the oil sending unit on a Daedong 3 cylinder used on the Mahindra 3510

Want to install oil pressure gauge and need fitting size used before I order the parts.

BSP NPT or Metric ? and what size

I would pull the plug and measure it up. A good set of calipers and some pitch gauges, or a check plate set. The thread check kits run $35 to $100 on Amazon.

Assuming that the sender you're removing is in good shape, you can get the thread gauge from a tap and die set and check the 1/8" NPT against it. If it isn't exact, it will be BSP. You could also research the part number for the sender and see if the thread is given in any of the descriptions. I'd do both, hoping they agree.

I've found lots of oil senders with metric threads; 10 / 1.5 or 10 / 1.25

The one on my tractor I couldn't source at all, I had to make an adaptor.

So if the OP doesn't get an answer, you need to either measure the old one or take it to a machinist or maybe a good parts store.

I hate to answer a question with a question but what about the dealer…. He should be able to tell you, then you go to tractor supply and buy one. I have bought stuff just to see if it fitted. Everybody else on here has give unclear advice so it looks like pretty much a guess at it and see. But if I were to guess I’d vote metric. Good luck
