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 supplier is classic-car spares company Catmint. All JOAC members are supplied with contact information

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 received no money from any business mentioned on any pages in this website.

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

Here below is an original Jupiter tool-kit, even showing the metal case  (separated from the Jupiter fixture behind the seat) that housed the jack

The list of small businesses is in no particular order:-

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".

But for car clock repairs, try Grant Hunt. His e-mail is [email protected]  and he is based just North of Birmingham.

He charges £70.50 to receive, clean, send a report (1.5 pages of A4) on its state, and then he asks permission to proceed. A Jupiter man reports that it took around a fortnight for Grant to ensure the clock was running accurately, repainting where needed. He adds a diode to stop the contacts destroying themselves.

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. Here are the relevant contact details:-

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.
