I must also say that yes I do question the earlier batches of LJ and LC carbs all having only one valid top brass tag number in relation for each set of different carbs .

If I have effed up about LC then I am sure Aldo and John Gong will set the record straight .

Did you Guy's find out about Gong's brass Tag's?

 

Thanks man.

We know all 6/73, 7/73, 8/73 & 9/73 LJ XU-1,s were fitted with the T226 TCX carbs........

But what was the one other component all these cars had in common with the T226 TCX carbs ? ? ?

 

This will test your knowledge......

The one other component fitted in production from the 1-7-1973, the same time the T226 TCX carbs were fitted was the larger front disc brake rotors.

Various other components were also incorporated into production throughout the months of July and August 1973 with production ceasing in September 1973 of the LJ GTR XU-1.........

Prior to the 1-7-1973 GMH had produced 500 1973 LJ GTR XU-1s.......

But there were no new bigger disc rotors. They were physically the exact same rotors that were fitted to all LC & LJ XU1's prior to 1/7/1973.

They may well physically look the same until you measure them..........

hahaha ERRATA 10/8V.

I have a set of original rotors that came off a 72 XU1. They measure 256mm OD also.

 

Errata 

www.dictionary.com/browse/errata

Errata is originally the plural of the singular Latin noun erratum. Like many such borrowed nouns ( agenda; candelabra), it came by the mid-17th century to be used as a singular noun, meaning “a list of errors or corrections to be made (in a book).”

 

 

If there were new bigger disc rotors then 10/8V would be an Addendum not an Errata.

 Picture 9th month 72 xu1 rotor 254mm.... the late 73 ones are 256.5 mm or 10.09 in.

Cheers

^^^^ Looks like 255.5mm OD to me.

Don't you mean : hahaha ERRATA 6/6V : There is no mention of brakes in amendment 6 (6/6V) only amendment 10 (10/8V).

While we have the dictionary out how about looking up : " ELIGIBILITY " " AMENDMENT " and " HOMOLOGATION "

10/8V is the Errata not 6/6V.

Big enough........

[grumpy xu1]

You're talking about 80 to 90 thou roughly, obviously you've seen the design of the rotor is slightly different itself on the 73 compared to the 72 & to be honest it was probably the cost factor in changing the design after the tooling was worn, there's a tolerance level on parts & i highly doubt that gmh would have said if we make these 80 thou bigger that breaking efficiency will gain x%
