Jupiter restorations.

[Keith Clements]

I put silicone jell on rubber to stop it oxidising and provide a torsional lube. Rubber grease may be an alternative. Also put copper grease on the bar ends. Do not forget that you should only tighten up rubber bushes with load ON/IN the car so that it is in its normally loaded condition.

I am at the reassembly stage & repairing things as I go.
I need opinions on reconditioning the front suspension. My car has the brass bush suspension & is worn more than I like.
I could recondition with out much trouble , however it has been suggested it would be better to convert the brass to rubber bushes.
I would like an opinion on this, & advice on how to do it.

[Keith Clements]

Look at 140. Conversion of Suspension to Rubber Bushed Type 54 in the Gallery for the parts required.
Other mods have been tried as on the NZ car of Peter Pfister. See Early Javelin restoration topic.
If you can recondition then you will find the steering more precise than the rubber. If you do, others may be interested in how you get it done.
The advantage of rubber is it takes less maintenance.

[PJGD]

Another possible alternative could be to re-engineer the suspension to use modern urethane bushes as are used on most modern cars; then you might get close to the steering sensitivity of the early bronze bush arrangement with the maintenance-free aspect of the Metalastik bush arrangement along with the long life durability that modern cars get. I don't think it would be a totally straightforward conversion since I have not seen urethane bushes that are dimensionally interchangeable with the Metalastik bush, but it would be a beneficial upgrade nevertheless.

There are four bearing areas that cause issue.

The lower pin does wear but replacements are available and easy to fit. The king pin itself may need some refurbishment but this has been done successfully many times using weld or metal spraying.

The torsion bar rubbers, which are the same on the rubber suspension, can be replaced with difficulty as outlined in the Josephine Rebuild topic.

The oil box long bolt and bearings are prone to leaking but, provided you use the correct O rings and follow the procedure suggested in the Early Javelin Rebuild to get the pinch correct on them, the leak can be fixed.

The upper worm adjuster wears, usually caused by a broken rubber boot allowing ingress of grit. This is more difficult to fix but try club spares or Bill Lock to see if they have a solution.

As Philip suggests urethane or other plastic could be used. There are companies that can do bespoke mouldings for classic cars as I have discussed at car shows with them. Try Google.

Thanks for the help. I can't seem to use the link to the gallery or find it using the search option.
Any ideas what I am doing wrong?

Hi David,
Your email address in the Australian members' register matches that in JowettTalk. My guess is that you are not logging in via the jowett.net home page, waiting for 'the Login to On-line Services' web page come up and then when your Personal Album page comes up in a new tab , clicking on the Board Index to get into the forum.

If you do not follow this sequence and click on JowettTalk before the session for the Gallery is set up you will not have access to it as a club member but only as a member of the public.

Also the Gallery session times out before the Forum session . The session can usually be reinstated by clicking on the JowettGallery home link, but you can also logout and login again.
A simple test to see if the system thinks you have a club member session is to see if you can see the Technical Library in the JowettGallery.

If you still cannot get in then please email me with a description or screen shot of any error message.

[David Kemp]

Thank you, I can now get in.As My son would say "user error".

[Keith Clements]

Good. I am sorry the system is not quite as easy as it could be but three systems needed to be securely integrated into a single sign on. There are different sets of information that have different security access levels that need to be managed. The public can see some things, registered users extra bits, club members even more, and administrators even more.

This forum is based on phpbb which is the most used forum software in the world. It is heavily modified to integrate with Gallery2 software which I still think is the best to manage the Jowett Archive. I am looking to see if there is a better alternative. So if anyone knows of better, please contact me.

Though the middle of winter here in Queensland, The Jowett run this weekend was still well attended.
Being QLD not cold allowing the Jupiters to arrive with tops down. Here are a few attendees.
