oil pressure switch

[Randyjh]

On my 1980 XS1100 my oil pressure switch started leaking out around the threaded wire connector. The only replacement I have found is used on ebay.
is there any other switch that will work that anyone knows about? Or where I can get a replacement. Thanks !!

That switch is nothing special, take it down to the auto parts house and match it up.

Greg,
That's great info, but I'm an ignorant putz. What am I matching? At what pressure does it make contact (or is it disconnect) and what else do I need to know? I know, to you it's simple, but you do it for a living. I would never have thought to go look at the auto parts store. I live in a box.

Mine is very slow to turn the light on.

It's just a ground switch Marty. It grounds the oil light circuit when the pressure is too low. I can't tell you what pressure but oil pressure is oil pressure. I would presume to say that if it drops below 5 - 10 PSI it will ground and kick the light.

The threads are just pipe threads and the only thing that may be difficult to match is the wire connection. It may have to be changed to a female spade end on the bike.

When I was looking at putting an oil temp sensor on my bike to work with my new gauge cluster, I was looking at using the fitting for the pressure sender. I think it was Crazy STeve that alerted me to the different pipe thread standards used for metric bikes vs. american or US standard pipe thread sizes, that there is a bit of a difference in the shape of the threads as well as the count/spacing.

SO...aside from matching up the diameter size, I would think we would also want an automotive one that was designed for Japanese/ Asian made machines(with Japanese pipe thread sizing) to help reduce the chance for leaking since it will be under up to 80+ PSI!

PS, I ended up drilling/tapping a new hole in my SOFA for the sender unit, but kept the OEM pressure sender as well, so I had both the light and the gauge!

If you have an engine running 80psi oil pressure you'll be washing out bearings and exploding oil filters if you have a spin on. BTDT

I agree on the threads though, however most American (so to speak) vehicles run a metric thread on everything now.

Quote from CS...


Pay attention on the oil sender thread. There's two 'common' 1/8" pipe threads, the US version which is 27 threads per inch, and the 'BSP' (British Standard Pipe) which is 28 threads per inch. The latter can be common on Japanese vehicles for some reason (hey, they do drive on the wrong side.. ) and almost impossible to spot by eye. If you even suspect that, check with a thread pitch gauge. One will 'fit' in the other hole, but leaks are common and it tends to trash the threads. DAMHIKIJK....

Well,

I wasn't too far off.....the manual states the relief valve pressure for the oil pump is ~71 psi +/- ~7, so up to 78 psi....close to the 80 I thought I remembered someone reporting that had an actual pressure gauge on their bike....must have been closer to ~60 psi! Still a decent amount of pressure which warrants the right pipe thread match to prevent leaks...thanks Phil for the quote.

i replaced the one on my bike with one from honda

fits the cx500/gl650/cb750/gl1100

and the yamaha lol

I used a standard 1/8" brass plumbing nipple and Tee from a hardware store when I split mine fir an oil pressure gauge. No leaks, everything threaded in easy.
