Oil pressure sending unit

[Nordicnorm]

When I bought my 07 Griso 5 years ago, I picked up a spare oil pressure sender. This was the one that needed an adapter between the block and the unit, as the original was no longer available. The other day my Breva's unit failed, and I installed this combo as a replacement. An awkward task to say the least. Had to remove the nut on the pivot bolt for the alternator for access, and it is a tight fit, but ok. A crow-foot to the rescue. The original female spade connector worked after heat-shrinking it.
Both my carcs have 100K km on them, so searching for a couple of spares, it turned out MG cycles have replacements now for the original, without the spacer being required. 12X1.50 mm thread. Not the nail-head, just a standard male spade connector, which works with the existing wiring.
Next time I have the airbox out, I will likely swap my latest handy-work for one of these, for easier access in the future. Cost is minimal.
Posting this as I have no idea how long these have been available. (Harper doesn't list them).

The original Pressure Switch (it's not a Sensor as such, it's either 'on' or 'off') is still available.
It's a generic unit used on thousands of Cars/Bikes.

This is a list of Part Numbers.


It's a direct replacement, original Connector plugs right in, no Adaptor required.
If your Loom has been fitted with the Spade type Connector for the newer Switch type, you can fit the correct connector again, it's a Bosch EV-1, same as the Injectors use, but with only one Terminal used.



Original on right.
Replacement Units are usually slightly taller, and have a slightly longer Thread, neither of which affect the operation or fit.
I did mine ages ago, and have replaced a few others for friends/others, no issues.
