MG Midget and Sprite Technical - Temp sender cable and oil pressure pipe routing

Hi, I'm currrently rebuilding a very standard RWA 72 and am trying to work out the correct routing for the temp sender and oil pressure pipes. Before I stripped it all the clips had already been removed and they just floated about. Parts catalogues just show the parts required but not where they go. I've got a few publications with various pictures but as ever you can't quite see where things should go. Any clues?

Temp sender folows the block back then coils 3 times then over the footwell through the bulkhead.
Oil runs over the heatertray shortest route.

Just from memory so we need a pic to confirm

temp sender does a U-turn above the alternator, 1st clip is secured on the rearmost alt mount bolt. Then runs along face of block, the 2nd clip is on the drop-down bracket hung off one of the heater tap studs. Then it jumps across to the footwell panel, with the three coils to take up the engine movement, it sits in the valley at the bottom of the sloping panel, goes across towards the outside of the inner wing panel, turns up the slope, another clip on the outside edge of the pedal box, up to the bulkhead, turns inwards along the bulkhead, then through the same grommet as the oil line, just before the battery tray. Should be stuff in the archive on here, possibly with a pic or two I took a few years back.

I just looked in the archive and I can't find any pictures. If anyones got a picture of the temperature sender routing I'd really appreciate it.

All I know from reading the archive is that my routing is not correct! I looked in the Moss catalogue and theres lots of clips etc, but I'm not sure how/where to fit them all!

Hmm, must get better at searching the archive.

Found this in the archive from SteveC. Not sure if the bracket off the heater tap is original or custom though.


TonyJH

Yes, that's a standard bracket.

Difficult to see from the photo whether the other bracket is fitted to the rear dynamo mounting bolt.

Thanks Dave. I've been through the Moss catalogue and I can't find either of the brackets.

I guess I can try looking through the box of 'unidentifed parts' the previous owner gave me in the hope that that's where they are!
TonyJH

I've just had a look in several parts books, including a reprint of the original Leyland book and can find no trace of them.

Even Horler's "Original Sprite & midget" doesn't seem to show them, although many of the cars in there have the capillary tube routed incorrectly.

I will see if I have any engine bay shots of my last Midget, which was very original, and had both brackets fitted.

Found one! here's what I've called the drop-down bracket, that hangs off the heater tap stud. It's made of 5/8" steel strip, and the long side is 2-3/4"


David Smith

meant to add - I can't find the clip that holds the capillary on the bracket, or the one for the alternator.
The various clips are listed and illustrated in the BL parts catalogue, page H98 items 12 to 15.
David Smith

Thanks Dave. I've phoned round a few places (Andy Jennings, Welsh MG, MGOC) and it looks like the easiest solution is to make up the brackets myself. The conclusion was that most people have lost these parts somewhere along the way (in fact no one could recall seeing them). As Simon says though, the evidence of their existence are the p-clips listed in the Moss catalogue.

I appreciate the picture. Off to find some 5/8" steel strip now :)

TonyJH

Awesome information!

Anyone got a photo of its route under the heater box / air intake tube?
Norm Kerr

Tony can you email me, I have found a 2nd one, you may as well have it, mgsmithy AT yahoo dotcodotuk
David Smith

Thanks Dave, email sent. As per Norm, a photo of the routing under the heater box would be good. Moss says that the capillary should be held with 4 p clips. That's one for each of the brackets (dynamo and heater tap), I guess one for heater shelf (or maybe two?).
TonyJH

yes on reflection I think it does run up the sloping footwell panel more or less alongside the oil line; I think the re-route round the pedal box was my idea to keep it out of the way on the racecar so it didn't get damaged during quick engine changes...
David Smith

OK, here's a photo of the bracket and clip on the heater tap. The capillary tube isn't routed too well, but I'll blame that on the PO


Dave O'Neill 2

And another of the dynamo bracket...


Dave O'Neill 2

Thanks for all the replies gents.
The plot thickens...
I've also got one of the said brackets, which if I remember rightly I removed from a breaking Midget although it was such a long time ago I don’t remember what Mk. The bracket colour is green so I assume it was pre Mk3. Do you think they may have omitted this bracket on the Mk3?

Any views on which bulk head holes the temp and oil pipes should go through. In the parts catalogue it says that each should have a different grommet. On mine both came through the bigger grommet C5574A. Which left a hole for the heater control valve cable.
Any pics...

Ooops, just re read the post and can see that SteveC's is a Mk3 and so is David's so ignore my ramblings in previous post.

David, pictures would be really usefull.

Thanks Si
