Post subject:  Temp Sender

Anyone know the size/thread etc of the mini's temp sender? I need one for my new gauges, I'm clueless if its not in metric :lol: I measured with vernier and got 15.5mm, but want to make sure I get the exact one..

Got this from Manufacturer..
All our senders have NPT thread:
SN22 1/8 NPT (10mm OD)
SN23 1/4 NPT (13mm OD)
SN24 3/8 NPT (16mm OD)
SN25 1/2 NPT (21mm OD)

Cheers
Mat

It is none of those... :lol:
Thread is 5/8-18 UNF, or 5/8-16 UNS, depending on who you believe.
Anyhow, I find a 5/8-18 UNF tap cleans it without taking any metal out, and they are way easier to get.

BTW,
Same thread is used for the bypass adaptor in underside of head. I make these out of BOC brass oxy hose joining nipples (5/8-18 UNF RH) and they screw straight in. Last forever... 8)

Thanks Doc..

Damn.. :cry: as for the figures, I'll run them by the supplier and see what they suggest.

The gauge requires a sender with the ohm range 240 - 33. (100F - 280F) Any idea what the standard mini sender uses?..

Most gauge places used to sell adaptors for these.
Sorry no idea of the resistance on Mini ones, but the Clubby was a little different to our Mini K, `Matic and Cooper S one.
