Sara there should be another part number on the body as well as a date, see if you can supply those.

We got a spare distributor with the TC several years back that doesn't fit. It is a Lucas #ECM 364 with a cap # 54417214. Can anyone tell me how to find what this fits or where we can look. I tried Google and nothing turns up. Maybe there is someone in our group that rebuilds them and can point me in the right direction. Thanks TTFN Sara [Non-text portions of this message have been removed]

Greetings, Thanks for the replies re: MG suspension parts identification. I'm leaning toward the Y-type MG as the source of these bits. I've located a woman locally that owns a YT Tourer and will go over to look at its front suspension to confirm. She mentioned that she and her husband own 3 MG's, the YT, an MGC and a CB Midget. The MGC has been apart for ten years since her husband started to restore it and inertia, by now, has a firm grip. There is a fine line between a running, driving car and a pile of greasy junk on the floor of the garage. Many of us have crossed that line before, and I wonder what percentage of those cars come back to life. Their Midget, still in one piece, doesn't run either. Naturally I asked if any of the cars were for sale and she said their YT might be.....and I am sorely tempted. What is one worth? Still looking for info on the distributor cams, there are 3 types for TC, TD and TF; asymmetrical, symmetrical and the latest style, high-lift. While re-bushing my TC and TD distributors, the machine shop mixed up the distributor cams. One is the symmetrical type and the other, asymmetrical. They both use .010-.012" points gap, is there any advantage to one over the other? While we're on this topic, is there a performance advantage to the high-lift type? Blower says the high-lift type promotes more accurate point operation, timing and longer point life by opening and closing the points quicker, cutting down on arcing. Pointedly, Jim Goodwin in Colorado Springs PS: I was asked to bring my TC to a Jaguar Owners Club meeting at the Concours Cars Shop (http://concourscars.com/home on Tuesday night for beers,bragging and bench racing. About 15 nice Jags were there including two XK 150's, some E-types and the latest supercharged whatever-they-are and the Jag guys voted the TC as the most interesting of the lot. Score one for the little guy! [Non-text portions of this message have been removed]

The distributor I have is a DKY4A 400488 DA34 946, is this correct for a TC XPAG engine? Maurice. [Non-text portions of this message have been removed]

Maurice, I believe you probably have the correct original TC distributor, but the number is 40048 ( not 400488 ) ./ If anyone has 40162 distributor, it is the same distributor and correct for the TC and early TD. Both give 15 degrees advance and 40162 superceded 40048. Advance curve is 279 for both. Bob Grunau, Canada Maurice, You have the "real deal" or as we say in the States the "Real McCoy".

Hi, All. The actual complete part number for the distributor in MG TC is 40048B. Maurice probably read the B as an 8. I have the Lucas specification page D57H for MG TC dated June, 1947, which shows that part number. 40048B was superseded by 40162A to E revision sometime prior to 1960, as the Lucas Master Catalogue printed in 1960 shows the supersession. Maurice is very lucky to have his original distributor!

George, Any thoughts on a 40048D? It came with the Gold Seal engine which is now in TC 9861. Michael DeRentz Broomall, PA [Non-text portions of this message have been removed]

The basic part number controls the specification, so you have the correct spec distributor for XPAG in MG TC. Lucas changed the revision letters for various reasons, such as changing the part number on the condenser when an improved one was used. All of the stuff that matters advance curve, rotation direction, earthing method, and advance range are the same for all 40048 and are correct for MG TC.

Hi, All. I was installing the distributor in TC3452 and noticed that with the special bolt to hold it tightened down that there still is about 7 degrees of rotational movement possible. Is this normal? There is no washers or shims on the special bolt assembly now. Is it something that is taken up by the micro adjuster? Am I missing some little parts? It is my first TC and I'm a bit confused.

The special bolt with the nub on the end, is to prevent the distributor from raising up, in the engine port. Rotation should still be possible, if installed correctly. The micro-adjuster has a clamp, that will hold the position of the distributor. Then, the micro-adjuster can operate, rotating the dist. as the adjuster is turned. John Seim Irvine, CA
