Ignorance is bliss! Until now I’d assumed Brabham’s 1966-1968 Repco F1 V8 engine rebuilds/freshen-ups were done back at RBE’s Maidstone, Melbourne base, but that’s not the case

“When we started to use the Repco Brabham V8s (the very first race for the new engine was the January 1, 1966, non-championship South African Grand Prix) it was clear to Jack that sending them back to Melbourne for rebuilds wasn’t going to work given the time it would have taken,” recalls Bob Ilich.

The Australian mechanic/technician worked for Jack Brabham Conversions, Motor Racing Developments (MRD-constructors of Brabham cars) and the Brabham Racing Organisation (BRO-Jack’s race team) during the 1965-1967 glory years.

“There just wasn’t the time between race meetings to fly engines backwards and forwards between England and Australia, the logistics just didn’t work.”

In 1966 BRO contested nine championship GPs and four non-championship events (remember those!), and in 1967 11 championship GPs and five non-championship races; Race of Champions at Brands, Spring Cup and International Gold Cup at Oulton Park, the BRDC International Trophy at Silverstone and the Spanish GP. This intense program yielded world drivers championships for Brabham and Hulme, and manufacturers titles for MRD/Brabham Repco in 1966-67.

In short, the season was very full from early January until the Mexican GP in late October.

Jack had a ready-made machining solution when the H.R.G. Engineering Co Ltd – founded by Major Edward Halford, Guy Robins and Henry Ronald Godfrey in 1935 – ceased trading in 1966.

HRG built 241 sports and racing cars in addition to their core general engineering work. In 1956 they stopped building cars, their engineering clients included Cooper, and later Brabham.

“When Jack moved BRO from the Canal Yard, Byfleet Road, New Haw Surrey premises (which had been shared with Motor Racing Developments) to Guildford in early 1966, ex-HRG machinist Ron Cousins and his equipment, lathe, milling machines etc were already there doing work for Jack Brabham Conversions which operated from an Esso Service Station in Woking.”

“Conversions did general service and tuning work, fitted Coventry Climax engines to Triumphs and Austin Healeys, made performance modifications, and later did the development work on the Brabham Vauxhall Viva/Torana.”

“The Guildford premises had administration offices upstairs including a drawing office for John Judd, who was back at BRO after his stint with RBE in Maidstone. He was in constant touch liasing with Norman Wilson, RBE’s Chief Engineer in Melbourne.”

“Downstairs was the Brabham Conversions Parts Department, a large workshop where the racing cars were prepared and the transporter parked, Ron Cousins’ machine shop and an engine rebuilding workshop for Jack and myself,” Bob recalled.

“After the first couple of runs in South Africa and testing in England, the engines had oil leaks Jack said we needed to fix. The first rebuilds were to address this, over time of course we did freshen-ups as required.”

“All the components we needed were sent from Australia including the new for 1967 700 Series blocks. I remember replacing three 600 Series blocks with the much stronger Repco 700 block, the three Olds F85 based blocks were still in a corner of the workshop when I left. If anything needed machining, Ron Cousins did it,” Bob recalls.

“By the end of the 1967 racing season the only thing we hadn’t mastered was the timing chain cover which still leaked a bit, but those 740 engines were otherwise bullet proof.”

“None of the engines were ever sent back to us for rebuilds,” confirms Michael Gasking, long-time RBE, Maidstone, Melbourne engine fitter and chief dyno test pilot.

“We sent engines and components over as they were needed, Jack and Frank (Hallam, RBE General Manager) were on the ‘phone all the time discussing updates and problems discovered at the track we needed to fix or enhance.”

So, there you have it, a little tidbit of RBE history not in Repco press releases or the history books.

Thanks Bob Ilich, I’m not sure quite how it popped into our conversation, but very much appreciated!

 Etcetera…

HRG

Among HRG’s products/enterprises were the original UK import rights for Weber carburettors, twin-cam HRG (Singer) engines, the Stuart Proctor designed crossflow cylinder head, inlet manifolds and rocker covers for BMC B-Series engines (usually marketed by VW Derrington rather than HRG themselves) and overhead-cam Ford 105E conversions.

HRG originally operated from Tolworth, Surrey and later Oakcroft Road, Chessington, also located in Surrey.

The then HRG director/shareholders, having reached retirement age closed their solvent, profitable business in 1966. Derringtons took over the drawings, patterns and moulds to manufacture cylinder heads and Jack Brabham acquired or absorbed the machine shop equipment and Ron Cousin into his group…

Brabham Premises

There is plenty of interest in Brabham, Jack Brabham, Ron Tauranac and Repco Brabham Engines at quite a granular level.

With an imminent trip to the UK, I’ve a couple of Brabham Sacred Sites at which I’m going to pay homage, with that in mind here is a list fellow Brabham Tourists may find of interest.

Please treat it as work in progress, I’m keen to hear from any of you with additional information to add, or corrections which should be made to this list.

Australia

Repco Brabham Engines Pty. Ltd.

This entity was the Repco subsidiary incorporated circa 1965 to design and construct the Repco Brabham race engines

A small team was initially located in a small part (the engine laboratory) of Russell Manufacturing Pty Ltd at 85-91 Burney Street, and 26-34 Doonside Street, Richmond. The first V8s were built there.

Nigel Tait picks up the story, “The engine lab that was at the back of Russell Manufacturing (Doonside Street, Richmond) was to service the then current Repco factories producing engine parts.”

“Once the Repco Brabham project started to outgrow that small lab, a decision was made to relocate it over to the Maidstone site that had been purchased from the original Automotive Components Limited company some years earlier. One of the four or five factories on that site was cleaned out and early in 1966 the manufacture and assembly of the RB engines was progressively transferred from Richmond.”

“The new company, Repco Brabham Engines Pty Ltd was incorporated, the Repco Ltd (parent company) Director responsible was Bob Brown, the General Manager was Frank Hallam.”

“Eventually a new test centre was built out the back, it was very sophisticated and state of the art with two dynamometers compared to what we had in Richmond.”

Michael Gasking testing RBE620-E2 2.5 V8 on the Heenan & Froude GB4 dyno in the old Myers garage – corrugated iron tin-shed – Doonside Street Richmond Engine Lab. The distinctive long-inlet trumpets allows easy identification of this engine as that used by Jack at the 1966 Sandown and Longford Tasman rounds. Mike is testing it either before the Sandown round, or immediately after it. The engine suffered oil pump failure and had to be quickly rebuilt before being sent to Longford…so it’s either mid-February or 28-29 February 1966 (Repco)
More sumptuous surrounds at Maidstone circa 1967. Very well equipped, RBE were set up to build engines with great precision in numbers. That two axis Cincinatti Vertical Acramatic milling machine (in the middle of the photo) is claimed by the man who sold it to Repco to be the first numerically controlled machine tool sold in Australia. The timing cover case lying flat this side of the vertical tape reader (the light coloured cabinet) was made on this machine (Repco)

“So, from about mid to late 1966 (the move started during the Xmas summer break of 1965-66) the whole of the racing engine project was at Maidstone and the engine lab in Richmond continued to service the Repco engine division.”

“Later, the same dynamometer set up was used for the (1969-1974) Repco Holden F5000 project.”

“In the meantime Repco started to move some of the piston and ring manufacturing plant over to the Maidstone site and for a while both sites operated as Repco Engine Parts – Richmond Plant and Maidstone Plant.”

“Then in 1986 Repco sold off the Engine Division to a management buyout and the same products continued to be made at the two plants though eventually all were consolidated at the Maidstone site, Richmond having been sold.”

“The management buyout company didn’t have a name and Repco kindly allowed it to be called Automotive Components Limited (ACL), so the wheel turned full circle,” Nigel Tait recalled.

The Richmond (art deco) buildings are extant, Maidstone became a housing estate close to a decade ago, below.

“The memorial at Maidstone was the brainchild and project of a local councillor about 2015. We had Michael Gasking and (now the late) Don Halpin (above) to cut the cake at the unveiling ceremony,” Tait recalled.

“Michael was at Richmond when I joined Repco as a cadet engineer, and I was assigned to work with him as his assistant on Repco Brabham with engine assembly and running the engines on our dynamometer (Heenan and Froude GB4).”

“Michael was (is) a good man, very skilled, a good teacher and very thorough. The engines he built won the 1966 championship and probably half of 1967 (Denny) as well.”

“Don, sadly now gone, was an amazing engine builder, worked in my team after Repco Brabham and the F5000 Repco Holden days on alternative fuel projects for the government, and post retirement built customer racing engines until the end. I miss Don…” recalls Nigel of his colleagues and friends.

Tailpiece…

Yeah, yeah, yeah, of course there are Jack’s businesses in Australia too (both before he went to the UK and after he left to return home) in the automotive, aviation and rural sectors but my focus is just those of the Repco-Period.

If we widened the lens we would be going for weeks I suspect…

Finito…

    Very good article about the Repco Brabham engine history. Yes they did rebuild the enginrs at BRO as we frequently sent over parcels of parts and gaskets. It is true though that one of Repco Brabhams success stories in 1966 was winning several Grand Prix “On the trot” as Jack Brabham put it with merely minimal change to the one engine. At one stage in 1966 an advertisement appeared in a British Motor magazine stating “French Grand Prix won on Vandervell bearings”.
    Repco were not happy but Jack explained that the UK bearings had polished backs and less lead overlay so .
    Repco very quickly rectified that problem with changes to our own product.

    The photo of Eric Gaynor using the tape controlled Cincinnati vertical mill would have to be very early as on the pallet on the floor are F85 blocks and Coventry Climax cylinder blocks awaiting machining.
