Oil filter fitting and pressure sender.

[Tim V-W]

This hereis the electrical connection on the oil filter housing on the 1800K I am fitting. Does anyone know if this is a pressure sender connection and if so can I use it instead of the screw in type currently fitted to my 1400?

 

The 1800 is from an Elise if that helps.

 

Thanks

This connection is for the pressure warning light only. It is a simple on/off switch rather than giving a resistance needed to supply a gauge. It is standard rover fitment.

Doesn't look like the OP sender on my 1800K (VVC from 2002)

had a feeling it might be for a warning light.

 

Guess I'll have to transfer the one from the 1400.

 

Thanks

Yep, you may need to add a remote hose line depending on the clearance from the alternator. Mine got in the way so I bought a hose to move it. Depends ont he alternator you use though.

Tim,

 

Been there and done that! You have several choices:

 

If your 1400 is around the same vintage as mine (1993), it will have a largish alterator and a vertical oil pressure sensor (with a 10mm thread I think).

 

It looks like your 1800 block used the later (smaller) alternator which has a different oil pressure switch (with a 12mm thread I think).

 

You can:

 

Buy the later type Sender (about £30 from CC), but I'm not 100% sure your alternator (if its the larger one) will clear it.

 

Use the oil filter housing and sender from your 1400 (the old gaskit should be o.k, but only cost 50p anyway)

 

Make up a remote pipe/adaptor and fit the sender somewhere else. I got some second hand bits to allow a sender to be fitted to the RHS of the engine out of harms way. I'm also fitting a later alternator and alternator bracket. (Thanks to RAW)

 

Hope this helps,

 

Bruce.

As Brucey, fit the 1400 oil filter housing and sender. Ive had no problems with doing this on my 1800. I also think the earlier 1400 items are more durable than the later ones.

If you use the CC sender (or any others with large holes to let water get in to the electrics) clean externally with meths, and seal all gaps (around outside of casing and around insulated electrical connector) with silicone - see recent threads on this.

Personally I'd fit an OS01A kit from Caterham and be done with it once and for all - it's the remote sender kit which comes with a new filter housing and all the relevant parts.

Hi Tim,

 

I am just getting to the end of my 1400ss to 1800ss conversion.

 

I used the 1800 oil filter housing as my 1400 appeared to have a hairline crack in it. I have a mechanical oil pressure gauge which I connected to the position that currently houses the electrical switch in your photo.

 

On top of the oil filter housing there is a grub screw, I removed this and fitted the oil pressure warning light switch. I have retained the big 1400 alternator and all seems to fit OK.

 

I could mail over some photos if you would like to see the finished article.
