Jowett Jupiter Spares and Service 

(and by definition Jowett Javelin Spares and Services)

To begin, here is a page showing how useful certain ramps can be. Scroll down to the last car - it is a Jowett Jupiter, that of Nigel Woodford

All the clubs listed on the Clubs Page supply spares, and often arrange for needed parts to be manufactured. There is a world-wide interchange of spares between clubs. The Jowett Car Club has a modest levy attached to its annual subscription; this provides additional resources for the manufacture of parts. The spares group can be contacted on Monday evenings 7pm to 9pm (UK time) on +44 (0)1274-604 455. Sales to JCC members only.

In particular Jupiter owners, especially those who are in the process of restoring their Jupiters, are urged to join the Jupiter Owners Auto Club and/or the Jowett Car Club (UK) and/or their Local Club (USA - Australia - New Zealand).

The Jupiter Owners' Auto Club now supplies its Jupiter spares only to Jupiters owners who are paid-up members. The Club's spares contact is John Powter who can be contacted at  jupspares [at] Tel: 01588-505 075

For New Zealand Jowett spares, you can E-mail Bob & Robyn Smith

For Australia Jowett Spares, you can E-mail [email protected]

There are a number of small businesses operated by Jowett enthusiasts, who can supply spares and reconditioned units etc. (ALL UK-based except KMC - see below).

Disclaimer: the Jupiter website only lists those known to be active. No guarantee can be given about the standard of workmanship. You are advised not to pay any money in advance.

I have neither sought nor received any money from any business mentioned on any pages in this website.

Before telephoning or using a phone/fax please calculate time-zone differences!!

An owner is happy with the engine work done by T & L Engineering of Elstow, Bedfordshire, and would recommend them to others. 

"The only disadvantage was having to remove the engine myself but I did learn a lot from the experience! The work was not cheap but was considerably more extensive than I had envisaged and it is not exactly a commodity item. On the advice of the local garage after the MOT I took the car to a nearby rolling road "doctor" After some tweaking it was rewarding to see the manufacturer's bhp being recorded".

For replacement carburettors the Weber 32IMPE and 32ICH have proved successful. There is a Dellorto alternative to the Weber 32IMPEs - the 32FRDA(e) - which are still available new from Dellorto.

With bpth these carbs, you either open up the inmlet port from 30mm to 32mm, or a manifold adapter/spacer has to be made, because the pcd of the flange bolt holes differs from the Zeniths.

Also, as the name implies, the choke diameter is 32mm as opposed to 30mm

There is a company name of Power Track Ltd who can supply Lockheed and Girling brake (and clutch) parts for cars from 1935 to 1980.

They will re-line your Jupiter brake shoes for you, with the correct soft grade of asbestos-free genuine 'Ferodo' material mimicking the original woven linings.

The original nominal diameter of both front and rear wheel cylinders was 7/8 inches

Richard Gane has found a source of more torquey starter-motors for the Jupiter. Made by Powerlite, or in full Eurolec Components (Midlands) Ltd, of Moor St, Brierley Hill, DY5 3SU the part number is RAC475, turning the correct way for our engines.
Richard says they are fatter than he original and you might have to put a small 'ding' in tyhe underside of the radiator. He says they work well on the three Jupiters he has fitted them to.

For such a rare car, not bad, eh?

Another type of supplier is the more general one, whose stock includes some parts used on Jupiters.

I have only used some of the companies concerned. They have not paid me to place this information before you - indeed they are almost certainly blissfully unaware that I have!

A supplier of electrical equipment is Holden Vintage & Classic Ltd. This company has a useful illustrated online catalogue from which you can buy.

The very useful Complete Automobilist has been taken over by the equally useful Paul Beck Vintage Supplies Ltd. -

Some Jupiter owners are resisting the temptation to spray-paint their beloved cars with twinpack and are sticking with tradition and using Coachpainting which is a very old method of applying paint to a surface using a brush.

Here is a website devoted to coachpainting and coachpaint and all you need to know to apply it successfully. If you access it you can follow a link to a blue Jowett Jupiter with black wings, presented as an example of the finish obtainable with Tekaloid Coach Enamel.

Very kindly Stephen Hull has volunteered to field paint-related queries - alas he has no paint formulae for colours earlier than 1962.
