Tools needed for Jowett jobs

[Keith Clements]

The discussion on head nuts has prompted me to think of what tools I would recommend to a new Jowett owner.
I am not an organised person so much of my time is spent finding a tool to do the job!

The Jowett supplied set provided with the car.

We should start off with the set provided with the car which we could assume was that required for general simple maintenance. But is that true and would you supplement or remove anything from that set?

The Jowett supplied set to the dealers.




Next would come a list of tools needed for the more major jobs, such as say a decoke or brake shoe replacement. What additional tools are required and what other tools might be better or easier to use? I ask this because in some cases a socket or a ring or a cranked ring might be better than the open ended spanner found in the car kit.

Then there are the special tools recommended for certain tasks. Which ones are necessary such that other means such as the bodgers tools of hammer, Mole or adjustable wrench and screwdrivers are really bad to use? I am thinking here of removing the ring that holds the front wheel bearing in on the Javelin or the hub removal tools.

Scattered through JowettTalk are lists and snippets that may answer these questions but how about bringing it altogether in this topic?
e.g. Page 10. tappet, crows foot, Javelin Wheel Tracking Service Tool, rubber fitment tools, various special tools, Some of the tools I have made or acquired over the years, original Javelin Tools, Appropriate Tools and Spares, Pre war tools,
The jobs.
Please add to this.
1. Head gasket change.
2. Brake system renovation.
3. Engine rebuild.
4. Gearbox rebuild.
5. Transmission overhaul including rear axle.
6. Suspension renovation including torsion bars.
7. Windscreen, Door and trim renewal.
8. Electrical including lights, dash, starter, dynamo control box.

Building the set of tools.
I have my in-car toolbox that has been honed over 50 years of Jowett motoring to get me out of most situations . Every tool has had to justify its inclusion as weight was always a consideration.

Then there is my extensive garage toolkit acquired over the same period that I now really need to sort out by labelling and cataloguing so as to reduce the time finding the right tool that I know I used twenty years ago.

What became clear at the restoration show is that additional tools are needed to strip the car. Shifting rusted nuts and bolts is always a challenge. Penetrating oil gives limited success and I use a blow torch to heat up bolts. This will be destructive to rubber components but they should be replaced anyway. Also take care that no flammable materials are close by. I did see a clever inductive clamp demonstrated at the show but it was very expensive. http://www.theinductor.com/ https://www.bolt-buster.co.uk/#4 https://www.ebay.co.uk/itm/220V-Handhel ... 3441817426

Big hammers, punches and breaker bars, air saws and hand saws, impact sockets, drills for rivets and spot welds, pry bars, grinder and cutting discs as well as tools for non standard fitments may be needed.

Jacks, engine removal support, axle stands, lifts or block and tackle will help if bodies are not available to assist.

Wire cutters, bags and marker pens will help separate and catalogue the items removed.

Have a look at the Early Javelin Restoration topic and other topics to see how some of the stubborn jobs were tackled.
