MG TD TF 1500 - More TD/c parts requested

Three final items needed.

Correct TD/c distributor Lucas mdl 40348A.

Correct transmission worm and pinion gear for a 4.87 final drive differential. Or complete transmission with same. Yes I know I can buy an adaptor or send the speedo out for recalibration if need be.

Would like to locate XPAG/TD 3/17292. In lieu of this; A mid design/production TD 2 block (Serial # roughly in the 14900 - 22900) that has the later design oil pump/ horizontal filter and the early style external distributor hold down. Earlier blocks are visually unsuitable because of the holes drilled for the vertical filter fixings as well as the filter to block pipe fixings to the oil gallery. Late blocks because of the cotter bolt distributor fixing.

If anyone has spares please contact me. I would like to keep the momentum going on this restoration.

Many thanks to those who have helped thus far.

Cheers

Hi Bill, you do not want or need to change the speedo pinion on the gearbox. What you need is the correct speedometer for your MK2 which is not the same as most other TD's unless they were factory supplied with a 4.875 rear end. The usual TD has a speedometer showing 1600 turns per mile on the dial and the Mk2 shows 1525 due to the change in rear end ratio from 5.125 to 4.875. The 1525 on the dial is the same as on a TF speedo since these cars also used a rear end ratio of 4.875.
If interested I can send you a picture on one of these 1525 TD speedometers.

Hugh thank you for the post. I am still interested in the block we discussed particularly since it is very close in production to what was installed in my TD/c. So please give me an update when you get to it if you have The Pistons that came out of it and the bores are straight I'll ask for them as well. If not I will have Arias make me another set of my spec Pistons for it when bored. I have not found another suitable one except a block with a Wolsey casting mark though it has a TD2 tag and the correct configuration, which now, really has me confused. Thinking it was a replacement engine. I have not made a commitment other than yours at this time. And if I find another it will be a spare. I'm thinking my engine is still around somewhere in NV or CA and hoping it too may be found at some point.

I will have to check my speedo when I get home as I'm not privy to whether it is a 1600 or 1525 TPM unit. I thought I read somewhere it was a change in the drive and driven gears on the transmission. I did notice a 1525 speedo on eBay recently but it didn't fit my needs at the time Thank you in advance

I'm still learning and will be the first to admit it.

Shock is on the way. Just looked at my speedo and it is a 1525 also. Man are those #s small. Forrest TD/C 22679

Forrest Rubenstein

A very special thanks to Forrest for coming through with an Andrex shock, rear arm and link which I recieved today

Also a thank you goes out to High Pite who came up with
XPAG/ TD 2/ 17498 that's less than a few hundred #s from what came in the TD/c originally. Would still like to find
XPAG / TD 3/ 17292

I am still searching for the following;
1) 40348A DK4Y
2) 1525 TPM late style speedometer
3) front arm for Andrex shock.

Cheers

Bill. I do have a spare TD transmission. Have no clue what it was out of. Anyway of identifying the transmission?

gears look ok, but I have not done a lot of looking at it. Bought it as a spare, but willing to part with it.

Have been away from the computer for a few weeks. My bad as I sent you the wrond arm. Have the front arm and will put in the mail friday. Forrest TD/C 22679

Forrest Rubenstein

Hi Forrest.

I haven't been here for a while myself. The front arm arrived as a total surprise to me yesterday. I sent a text to your phone but didn't get a response. I will try to contact you directly tomorrow. I've not been well this last week. Thanks so much. I now have a complete set of shocks ready for overhaul.

Bill,

I have a 40348A distributor dated 10 52, on my td2. The strange thing about this model is that it is not listed anywhere in the Lucas documentation. I was not aware that it was used on a TD/c. Contact me off line to discuss further. "john dot scragg at wanadoo dot fr"

Regarding the 40348A, some years ago I was in correspondance with Chip Old***, who sent me information on all the distributors in XPAG and XPEG engines, so I have attached the data for the 40348 distributor. The suffix A means it had the early 406329 symmetric cam. Chip does not show the 'Type', so it would be helpful if you could let me know the Type, which is normally contained in the body stamping or engraving; DKY4A/type?/40348.
In this connection, if anyone has a DKY4A/?/40197 distributor, I would be grateful to know it's type.
*** of the USA, but I think, sadly, no longer with us.

The type stamped on the body is DA41, this is surprising, as this type is mentioned in the Lucas doc. as being a D2A4 not a DKY4A model. Could this be because they both have the same ECM curve (364) as noted in your attached data sheet.

Would it be possible for you to send me the complete set of data sheets on these distributors? Or even better, make them available on this BBS.

John

J Scragg

Hi - in other correspondance with Chip Old he says that he obtained all his data from Lucas Engineering Department in the form of photocopies of original parts lists, specification sheets and ECM curve drawings - and his contact was L H Foster, Parts and Service Division, Lucas, Birmingham.
The 40348 sheet mentions it is roughly equivilent to the 40367 distributor, so I have attached Chip's sheet for that distributor. The model is D2A4 and type is DA41, which match what you say. It appears that all clamp plate/micro adjust distributors are either DKY4A or DKYH4A, and all cotter bolt distributors are D2A4 - perhaps you could advise the securing method on your engine. Regarding whether the DA41 refers to the 364 ECM curve, there are other distributors with the same ECM curve (not 364), but different type numbers - a bit of a puzzle!
I will check what other info I have.

I have these if anyone is chasing them

RA,

Thanks for the data sheets. from these and other sources I have made an excel sheet showing the advance curves for the 3 DKY4A distributors used on the XPAG engine.

Attached is a snapshot of these, If anybody is interested in a copy of code let me know. It can be used to plot curves for other distributors.

John

J Scragg

Thanks John.

It is my understanding that that early MKII used the 40162 as well but different springs were used from the std 40162 to change the advance curves. I don't know if there was a different letter designator.

I sent you a follow up email regarding your 40348A. Could you email a picture of the housing out of the engine only if you decide to switch it out. If you didn't receive my second mssg let me know. Thanks

Bill Chasser

TD/c 16920

W. A. Chasser

Apologies for delay, but 40162 attached. No change of springs, but other minor changes; suffix A,B,C used symmetric cam, and D on used high lift cam.
