Post subject:  How to replace the oil pressure switch??

Hi everyone,

Another question that has probably been asked a million times before (however my searches didn't turn up anything useful).

Is there a simple way to remove the oil pressure switch without having to remove the dizzy etc??

My switch seems to be leaking oil when the car is running, however I don't actually seem to have the room to get a spanner in there to remove the old one.

On a side not as well, has anyone had any experience with the new oil pressure switches? The new one seems much smaller than the original that is on there, however I haven't actually been able to get the old one off...so the thread could be the same size.

Thanks in advance,

Richard

no, but put a scratch or pencil mark on the dizzy and the mounting plate so you can put it back where it came from and it'll be fine...

the thread is 1/8" BSP

It should not be real tight, grab the body with multigrips. Or, heat & bend a spanner to fit in there

Ok, sounds not too bad.
The thread is hopefully the same, its just the old switch unit seems so much bigger.
Any idea what size spanner? I've gone to the biggest I have lying around but can't find the right one. Maybe I just can't get it on there properly though....

Multi-grips. That is what you need.

I use a special deep socket which I purchased from a cheep tool shop. It was made for the job and works a treat. No need to take any crap out of the way - just the grill if you don't have the correct length extension bar.

Sounds good. I might give the multi-grips a go first seeing as I already have them.
Do you know what size socket it is (just incase).

It does two size's. 1" and 1 1/16"
It has a special hex to suit the switch.
The brand - good old chrome vanadium.
