oil pressure switch, rip off or cheap chineese rubbish ?

[simonfraser]

from a 'proper' site around £90 for one switch

Alibaba, $5 each if i buy 10 .....

any experience ?

 

[Mr Googler]

I’ve just bought a proper one so bettter not be any good

I bought a regulator for a honda bike, £10 from china, melted in five minutes.

Welcome to the world of volvo penta parts,Think of it as insurance!

I suppose it depends what that switch does.

If it just causes the old pressure gauge to fail then fine.

If it triggers a whole host of things on the ECU stopping the boat in the middle of nowhere then maybe not.

Buy a 5 dollar one and have a look at it!

These folks do danfoss stuff .
Not sure what VP use ?
However MAN use off the self danfoss sensors .
M and M.s - same part is 1/4 price of a Cote d Azur official MAN agent .

They are pretty helpful too, heard it all before etc :encouragement:

Generally no that's not suitable as it's not insulated earth type .

 

[Mr Googler]

Having just changed my starboard oil switch, I would be less worried about the price and more worried about how to get to the bloody thing!

Only 3 days to get it done with much shouting, cursing and bruising

If only volvopaul was manx based

Hehe, mine is as easy to get to as my shoe laces

Here you go from RS range 14 - 24 psi I think the VP is set to 18 psi.

For NO 821-3566

For NC 821-3582

 

[simonfraser]

Hm, interesting they can make similar for £20
The connectors are totally different, is a push in system with a small plastics toggle on the side for the VP part

how about this then?

I would be more concerned about the cheap Chinese switch failing and dumping the oil, don’t think you would get any warranty from Alibaba, the Chinese are very good at copying things but never as good with the quality and bearing in mind the cost of a replacement engine I know what I would do

 

[Trundlebug]

You could just take your old one into your local (decent) motor factors and they'll find a suitable replacement for you.
No fuss, waiting or P&P.
Should be less than a tenner

Lop the VP connector off and crimp on some loops or spades as necessary. There are only two wires.

Just done some research and before you go cutting any plugs off and fitting a pressure switch as shown above, the VP switch provides a signal to the ecu for oil pressure gauge and warning light so confirms that it’s more than just a switch.
If this is the kind of repairs that are done then no wonder people are complaining about the reliability of electronic engines

I'm sure there are plenty of modern car or truck engines with the same features. As I said, a visit to a reputable motor factors will more than likely find an identical part at fraction of the cost
