Replacement Oil pressure transmitter won't fit.. NOW SORTED!

Hi, I bought a replacement oil pressure transmitter for my V8 as the original sender only works when it feels like it, which isn't very often. Anyhoo, I got one from Wins but when fitted, the hex head catches the bottom rear edge of the timing cover? before it seats on the washer. I've had to put the original sender back in. The upside is, while it was out, I cleaned it thoroughly & polished up the spade connectors and it seems more willing to work. Anyone else had this problem fitting a new sender? It was an absolute mare of a place to get to even with the alternator & bracket removed, and utilising the 18mm spanner chopped in half. One thing I've just thought of, though, is there any problem swapping the positions of the oil pressure & oil warning light sensors over? Are the threads the same? I've also heard bad things about the later (black plastic) pressure senders having a tendency to leak after a short time. I'd quite like to get the pressure gauge working correctly.
 
Re: Replacement Oil pressure transmitter won't fit..

I had a similar problem, i brought one via the local rover club, but the thread was differnet, i then went to a 2nds rover parts dealer who adivsed me to use a jag manufactured sender, and it fitted perfectly, my oil psi reads 60 and under accerleration and then 4o on idle, i get the same contant readings so i know its correct, the other one was just stuffed

I also had the same problem with my oil pressurse switch, the thread was differnet, i pulled one off a rec, and it just screwed in!

might be a bit of trial and error!

good luck, ill find the jag no details and re post

Re: Replacement Oil pressure transmitter won't fit..

Hi Tony , had the same with mine , had to "relieve" the front cover with a file :? And the gauge seems to read high , but it might be telling the truth :?: See thread .

Re: Replacement Oil pressure transmitter won't fit..

Cheers Guys. I did think about filing the cover a bit, but was worried about getting filings in the hole where the sender goes, especially as I only changed the oil a couple of weeks ago. :roll: . Needless to say, when I put the old sender back in to prevent this, I couldn't get the file in to do it... What I need is a blanking cap fitted temporarily, then I can file the required corner off a bit. I suppose I could jam a bit of clean rag in there though.. I also need to get a deep socket the right size, as none of my sockets or spanners go that big. :shock:
 
Re: Replacement Oil pressure transmitter won't fit..

The one i got through my local club was a Jaguar 50 psi sender no c15474


fitted like a charm and had no problems, and get the same readings all the time
 
Re: Replacement Oil pressure transmitter won't fit..

It might fit but the range of pressures it measures might not be the same
 
Re: Replacement Oil pressure transmitter won't fit..

True, the pressure gauge goes up to 60 psi, and I think the sender is a 50 psi sender, so I'm assuming it'd read a bit high. However, since cleaning out my original sender, with a squirt of penetrating oil and cleaning up the terminals, it seems to be working again so far. My next problem is my rev counter. That's given up the ghost. I'm wondering if the pertronix ignitor & flamethrower coil have killed it. But thats a whole new thread...

I had to use the jag one, and i get the same constant reading, 60 psi under acceleration and on idle 4o psi, on a really really hot day 30 psi, so i fugure i get the same reading all the time its working, and it can be that far out?
 
Re: Replacement Oil pressure transmitter won't fit..

That is reading a little high, but not stupidly so. My gauge with the original sender (when it decides to work) reads about 40psi on acceleration, 30psi on cold idle, and about 15-20psi on hot idle. I like the idea of the original type construction, as I've heard the ones with the black plastic cap can start leaking quite quickly. As long as I'm getting consistent readings, I don't really care if its indicating a little high, I don't suppose the gauge is that accurate anyway, I mean its not a scientific instrument, is it?
 
Re: Replacement Oil pressure transmitter won't fit..

There are two ports on the oil pump front cover, one for the oil pressure switch while the other accepts the pressure transmitter. As both ports are in series and see the oil as it passes back into the engine, the orientation of the senders can be swapped with no ill effects.

So if there fouling between a replacement sender and the timing cover, just swap both senders around.

Strange, I've just got hold of one of these, genuine jag same part number, but the thread's too big in diameter to fit. Luckily I tried it on an oil pump cover I have in the garage. My old sender screws into it, but the jag one won't. Its on its way back for a refund now. I'll just have to put up with my old intermittent one for now.
 
Re: Replacement Oil pressure transmitter won't fit..

After a tip-off from SydneyRoverP6B, (thanks for that!), I've ordered a correct spec sender PTR1812-06 from THESE guys. Part cost $68, shipping $40 from the USA, so the whole lot shipped will cost me about £68 all in; the dollar/pound exchange rate helping a bit at the moment. 8) That's for an original spec Smiths Replacement part. Not too bad when you consider one of the generic ones with a plastic case costs about £52 plus P&P. Shame you can't buy these exact parts in the uk at all... :roll:
 
Re: Replacement Oil pressure transmitter won't fit..

Excellent...and a good tip from Ron! :)

Or you could fit a mechanical gauge for about the same money and take all the electrickery out of the equation.

Re: Replacement Oil pressure transmitter won't fit..

I'm beginning to wish I'd done that now... I've just fallen foul of our wonderful HMRC, who have just clobbered me for another £21.30 for import duty and their handling charge, the part itself was only £42 .. :x :roll:

What really gets my goat is that I had to resort to a US import of a British part, for a British car, living in Britain, because I couldn't get the part in the uk. I mean, its a Smiths part for gods sake!

Hi Tony,

Gee U.K Customs are a bit steep... :shock: I have only run into trouble as far as having to pay Customs duty and GST when the total value of the item including the delivery fee exceeds $1000 (approx 650 Pounds). When the total value is less, there are no additional charges to pay.

Look forward to seeing the photos of the new sender, hope it works a treat!

Re: Replacement Oil pressure transmitter won't fit..

The funny thing is, its a bit of a lottery. I've bought quite a few bits n bobs from overseas in the past, sometimes you get charged, sometimes not. What annoys me is that the uk charge duty not only on the goods, but the shipping costs too. Plus a handling charge on top. :x :roll:

Makes my sender unit quite expensive at about £85. I probably could've made it a bit cheaper by buying several of them, and selling the surplus on ebay. Shipping would've been cheaper per unit, and the handling charge would still be the same. Could probably have sold them on for a small profit each, which would've helped.. Still never mind.. Hopefully my problems will be resolved for a while now....
 
Re: Replacement Oil pressure transmitter won't fit..

I know this is more on the topic of Customs charges than P6 electrical, but here's my story!

You may know of a certain group of films called Star Wars. In fact, in the 3 prequels, George Lucas (who imagined and created the Star Wars) even had the cheek to use my nickname as the name of one of the main villains! :evil: :LOL:

In 2005, when Episode 3 (Revenge Of The Sith) was released, a US company called Master Replicas made a life-sized licenced replica of Darth Sidious' lightsaber

74577.jpg


If I purchased it in the UK (via a UK shop), it would have cost ~£350. I opted to buy direct from the USA, at a cost of ~$370 (which was ~£230 at the time). I got it and I was pleased, it was a high-quality replica.

Some weeks later, I received a bill from the UK couriers for ~£58, which I was somewhat surprised at; I had paid the carriage with in the original payment! After phoning, they explained that the replica had parts that contained GOLD, and that the UK customs are insistent on having some form of import duty because of this.

Of course, it still worked out significantly cheaper all in all, but it wasn't as much cheaper as I had hoped for, so that was my first falling into the UK customs duty "trap". Also, had the exchange rate not been as favourable when I purchased it, I'm sure the saving would have been much less, if not actually totally cancelled out, or even actually cost more overall!
 
Re: Replacement Oil pressure transmitter won't fit..

Well, my pressure sender has arrived, all duties paid, and I have to say overall I'm quite pleased with the experience. The only annoying thing is, the replacement part says "Made in the UK" on it... I'd like to know if & where one can buy this part here. Here's some pics, compared to the original unit..
