Sump Plug Thread

Can anyone tell me what type of thread a standard sump plug has?

 

I've got a HKS oil temp sensor, that's supposed to plug into the sump. The sensor itself is smaller than the sump hole so I need some kind of adapter to convert it from its current thread to the sump thread. When I came to do an oil change the original adapter was thread bear :eek: so I had to fit a standard sump plug. I seem to have lost the old adapter now and could do with some help sorting out a new one.

 

Thanks

Alternatively we do a relocation kit - part of which is a remote head that holds the oil filter which has two fittings -

 

Into one of which you can thread this sensor (and the other can be used for oil pressure sensor at a later date if required)

 

Give me a mail if you want details

 

Regards

Post a similar quality photo of it next to a standard sump plug, or tell me the exact thread and pitch size of the oil sensor. I may be able to make you an adaptor. Obviously, it can't be done if the sensor thread is nearly as big as the sump plug thread, i need a reasonable amount of wall thickness left when i tap an adaptor to go into the sump hole, and drill and tap for the sensor. Plug is metric fine thread.

Actually, thinking back, i have made an adaptor for someone else on this list. the thread size was too close to the sump plug thread size, so i turned and tapped and died a stepped adaptor, so the tip of the probe was in the oil, and the threaded part was further out. I have to warn you any 1 off machining work ain't cheap, I'd want 50 quid to make another, it's a fair bit of time to do these as single items, and not enough demand to write a CNC programme to do a batch. I'd need the probe too, to check on thread size and pitch.

The problem is as Chris identified - the sump bolt is very small and cannot really take the required thread diameter for the sensor to be plugged straight in

 

I am sure that it has been done - but cant see it leaving 5mm either side

 

Hence the reason why I went the relocation route initially when trying to fit the sensors in place (I have oil temp and pressure) - and the filter is a pig to get to unless jacked up

 

Mine is now happy under the nearside headlight - which doesn't take too long to get at:thumbs:
