Bugger!

Led Zeppelin first recorded ‘Communication Breakdown’ in 1969, although it was part of their live set from 1968. My whacko brain thought of that song and riff upon seeing this bit of ye olde school communication…

It would have been perfect if the song originated from 1967 given the date of the Brabham Racing Organisation team-leader’s (thaddl be Brabham JA) letter to the General Manager of Repco Brabham Engines Pty Ltd, Frank Hallam Esq is, according to Rodway Wolfe’s handwritten scrawl, 24 May 1967.

These days we have that internet thingy which makes our lives so instant in terms of communication, back then it was ‘snail mail’ or Telex machine if you were from the big end of town. I guess airmail from Surrey, UK to Maidstone, Victoria, Australia was three days or thereabouts? And the same in return with a neato ‘Par Avion’ sticker and a more expensive stamp affixed.

Jack’s note was sent between the Monaco and Dutch GP’s.

BRO had shown plenty of pace early in the season with Brabham and Hulme on pole and with fastest lap respectively at Kyalami albeit Pedro Rodriguez took the South African GP win in his Cooper T81 Maserati.

At the following championship round- Monaco, Jack was on pole deploying the new RBE740 Series V8’s power and big, beefy mid-range punch for the first time in a championship round. But an unhappy early ending to the weekend was the Aussie’s new moteur breaking a rod on the first lap of the race. Denny won his first GP in a 620 engined BT20, so it was far from all bad from the team’s perspective- the race tragic for the sad demise of Lorenzo Bandini after a fiery crash aboard his Ferrari 312.

Merde! or Australian vernacular to that general effect- Brabham checks the hole in his nice new 700 Series Repco block, carved up somewhat from an errant conrod- Monaco 1967

But all the same their would have been a bit of consternation in the camp at the time, no doubt a phone call to Hallam was made about the buggered rod, or maybe Frank read about it in the late edition of Monday’s Melbourne daily ‘The Sun’?

The Lotus 49 Ford Cosworth DFV changed the GP world when it appeared in the hands of Clark J and Hill G at Zandvoort on June 4- the need to lift was clear!

So, lets address Jack’s requests.

Sorry about that sketch of Brabham’s requested 700 Series block modifications! Sadly we don’t have it- which is a bumma.

The modified Daimler rods and caps are RB620 bits, not 740- so Jack is after some bibs and bobs to keep alive some of the RB620’s by then in circulation in Europe. Not to forget Denny was still using RB620’s until he got a 740 for Spa in mid-June. The ‘620 Series’ Repco was the first of the Repco Brabham Engines series of race V8’s and was based on the standard Oldsmobile F85 block- ‘600 Series’ block and ’20 Series’ cross-flow heads in Repco nomenclature. The ‘740 Series’ was the new for 1967 motor- ‘700 Series’ bespoke Repco designed block and ’40 Series’ exhaust within the Vee heads.

The water rail changes appear routine race experience evolution, in fact whilst the whole letter is dealing with normal stuff its still interesting, if you know what i mean? And the engine fitters will have been given the bief to watch the chain tensioner fit.

Jack’s checklist of engine parts is interesting.

I thought all of the RBE engine rebuilds happened at Maidstone but clearly that is not the case, some engine work was being done in The Land of The Pom. Interested to hear from you RBE lads on this point.

The photograph above is of the two participants in the above correspondence at Sandown Park, Melbourne during the 1966 Tasman round. It is a ‘pose for the press’ shot given the race debut of the Repco V8 in the companies home town.

It was the second race for the RBE620 Series V8- the first was a 3 litre unit used by Jack during the non-championship South African GP weekend on 1 January, DNF with a fuel injection pump problem.

The engine above is a 2.5 litre jobbie- easily picked by its long Lucas injection trumpets, this time an oil pump broke- the chassis is the one and only BT19 which carried Jack to the 1966 title, and as can be seen in the Monaco photographs, well into 1967. The RBE620 became a paragon of reliability after some initial traumas were rectified…
