Gearbox Identification, Herald/Dolomite type

[Sidd]

I have gearboxes with the following prefixes: DC, LG, CB, WE which don't match any of the listings I can find. What models are they from?Whitley (on hill above coastal village).pdf

[PeteH]

I can tell you the CB is a Herald box. Mine is CB22**** in  1971 reg 13/60 Convertible.

Ive got a WE unit and I think its was decided to be from an Dolomite 1850 but a very early type same as Vitesse/GT6 HC or KC units with small main shaft tip and small synchro rings. Its input shaft should stick out further than the other gearboxes you have....

[thescrapman]

Photos from further back may help, or list input shaft type and length, and size of output flange.

CB is possibly a badly stamped GB.

I think thr LG is DG

[Colin Lindsay]

CB and WE are the easier ones, but did the TR series use the same gearbox casing for the earlier models? Their prefixes are CT, LE and LF, so possibly LG could be a variant? CC and CD boxes were used in the heavier TRs like the TR6, so might be an option for DC? I've found nothing closer to LG or DC so far.

Similarly I was trying to check MG gearbox numbers or Standard models but nothing yet.

I've seen more than one CB box (might actually have one) and will post a photo if I can find it; it doesn't look like a bad stamping if I remember correctly.  DG is another Dolomite box.

[thescrapman]

I reckoned n the DC is also DG, but the lazy guy on the gearbox line couldn't be arsed to look for the G stamp, and C is close enough. Or the G was worn out so he used C perhaps?

No. I think all the TRs from 2 to 6 used the saloon type gearbox. Similarly, the only MG / Morris application of a Triumph box was the single rail type, so that's not it either.

I agree with scrapman that the LG is probably a badly stamped DG.

[johny]

That fits in with the quality of stamping you sometimes see! Perhaps thats being unfair though, maybe they only had 30 seconds to do it before the box was whisked off on the production line and, if not, a car would be delivered somewhere without a gearbox😁

Photos of my CB box, just for info:

the number really doesn't mean that much anymore, the case could have any gearset in after 50 years plus of recons and they may well have been re-stamped.

Restamping or overstamping is very noticeable. This one started off as FK and ended up as GH. 

People always talk of matching number cars where all components are the originals, so where a Triumph with its' original rebuilt engine is always going to be considered worth more than a replacement unit, I suppose the same is true of gearboxes.

just not so easy to read 

saw an advert for a 57 moggie minor on original tyres  ...thats a real must have for originality    Nah 

the originality thing is a bit nuts .............triggers broom comes to mind 

or  Henry's head chopping axe    same old ???

Possibly, but imagine you're buying yet another Triumph ( ) and the owner tells you he's had the original engine rebuilt. Sounds good. You go to look at another one and that seller tells you he's thrown away the original engine and stuck another one in from an identical car. To many, that means the first owner was caring enough to look after his car and repair any wear; the second was possibly more practical or maybe a cost-cutter. It all depends on what you want but the guys who spend big money on classics seem to put store by it. It doesn't really matter as much in a £50 Herald... but it's a bonus.

[DanMi]

Some of those numbers do look odd as the stamps are clearly different sizes (particularly CB 253192 so not from the same set. Could it be that a reconditioner bought a lot of cases and stamped them, with their own codes. Not sure that anyone would care about a matching no gearbox as they were never recorded outside of the production line and the numbers didn't match like on some manufacturers.

 

also, Did the New Zealand assembly plant use different codes?

[Peter Truman]

My understanding of AMI Aussie CKD assembled cars was that engines, gearbox's and diff's came out from England fully assembled so would have UK numbers stamped on them.

For confusion the Spitfire G/B I recently rebuilt uses the MG 1500 Single Rail internals that I put into a 3 Rail Box that actually has a GT6 case & number!

It is completely irrational, though I do like that my Vit has org engine (maybe due the engine, considered the heart of the car?), (and to a much lesser extent, things like wiper motor, dynamo, dizzy, as well, A good chance org, as same date stamp on them as car year?). Though as GB is a J Type O.D bitza, I'm just glad it has an O.D.

It's definitely, not a value issue, more, I'm just probably a bit higher on the Spectrum, than average, which is ok.   

[Sidd]

Thank you for all the responses. Was hoping for an easy way to identify expected contents of the boxes but will need to do some counting and measuring. All the markings look original so a collection of production line 'freedom of choice' stamps. Thanks again.

[Colin Lindsay]

Can you post photos of the complete boxes that are stamped DC and LG? It may be possible to spot something from the box itself rather than the stamped number.

[ahebron]

Like Peter said as in Aus  NZ Triumph bought in from the UK assembled drive train components.
NZ assembled Triumphs have the prefix 3 on chassis numbers.

 

[johny]

Pretty sure the LG is really DG as Ive seen a few examples where they didnt get the angle of the stamp right. So that would be from a Dolomite/Toledo 1300/1500...

[Josef]

There's a listing of which gearbox / engine / diff codes were originally supplied with which Triumphs here. I'd assume it's fairly accurate as most of the info is a copy of an e-mail from John Kipping https://www.teglerizer.com/triumphstuff/spit_and_gt6_specs.htm Doesn't cover some of the prefixes discussed though!

[johny]

yes one missing is the infamous WE which although quite common doesnt seem to be listed anywhere...
