Introduction to the Jaguar Mks 1 and 2, 240 and 340
The Jaguar 2.4 Mk 1 introduced in October 1955 was a departure. A departure for the Jaguar Company and a departure for the dulled post war years of motoring. After a considerable time of development the Jaguar 2.4, using Jaguar’s XK engine (decreased in stroke), gearbox and steering gear of strong repute, appeared as a new monocoque construction; all previous Jaguar models having the conventional separate body and chassis. The 2.4 was an exciting car by the post war standards – over 100 mph performance, reasonable economy, great comfort and a very ‘slippery’ shape all at a price of £1269 and 10 pence including purchase tax, all in a 1955 4 door saloon.
It was not until February 1957 that the Mk 1 saloons really became significant. The full XK engine of the time, the 3.4 was installed in the same 2.4 bodyshell. Then in September of that year, 4 wheel disc brakes, wire wheels, automatic transmission and overdrive were available as options. It was now possible to buy from the showroom a luxury 4 door saloon and have one of the fastest (120 mph), best braked and most stylish cars available, all for about £1600.
October 1959 saw the next significant announcement. The Mk 2 series appeared supplemented by the 3.8 litre saloon. This was an even more powerful version, now with 220 bhp and a limited slip differential as standard. The visual changes were a slightly larger bodywork, much larger rear screen and higher door pillars on the same waist line giving a ‘taller’ appearance. Internally the Mk 2 had a wider rear back, improved front suspension, disc brakes as standard, dual exhaust system and many interior improvements. Until September 1967 many minor changes took place but the basic three cars remained. Power steering was made available.
The 3.8 was discontinued in September 1967 whilst the 2.4 became the 240 and the 3.4, the 340. (The 3.4 and 3.8 ‘S’ types introduced in 1963 continued after 1967. They are not dealt with in this manual although their specification is somewhat similar). The 240 and 340 are very similar to the earlier models, although some trim was removed and an ‘E’ type type cylinder head was installed on both models. Production of the 340 stopped in September 1968, the 240 in October 1969.
The Mk 1 and 2 series is a very significant car in the annals of motoring. It finally convinced the world that performance, comfort and reasonable economy could be had from a 4 door saloon at a very competitive price without any loss of tractibility and carrying capacity. From a competition point of view it also showed that production saloon cars can handle racing speeds. Anyone who has seen four 3.8 saloons, two dark blue and two in off-white, with head lamps blazing driven by four grand prix drivers sweeping round 90° bends in perfectly controlled four wheel drifts, will know just what is meant by this.
About this manual
The aim of this book is to help you get the best value from your car. It can do so in two ways. First it can help you decide what work must be done, even should you choose to get it done by a garage; the routine maintenance and the diagnosis and course of action when random faults occur. But it is hoped that you will also use the second and fuller purpose by tackling the work yourself. This can give you the satisfaction of doing the job yourself. On the simpler jobs it may even be quicker than booking the car into a garage and going there twice, to leave and collect it. Perhaps most important, much money can be saved by avoiding the costs a garage must charge to cover their labour and overheads.
The book has drawings and descriptions to show the function of the various components so that their layout can be understood. Then the tasks are described and photographed in a step by’step sequence so that even a novice can cope with complicated work. Such a person is the very one to buy a car needing repair yet be unable to afford garage costs.
The jobs are described assuming only normal spanners are available, and not special tools. But a reasonable outfit of tools will be a worthwhile investment. Many special workshop tools produced by the makers merely speed the work, and in these cases guidance is given as to how to do the job without them, the oft quoted example being the use of a large hose clip to compress the piston rings for insertion in the cylinder. But on a very few occasions the special tool is essential to prevent damage to components, then their use is described. Though it might be possible to borrow the tool, such work may have to be entrusted to the official agent.
To avoid labour costs a garage will often give a cheaper repair by fitting a reconditioned assembly. The home mechanic can be helped by this book to diagnose the fault and make a repair using only a minor spare part. The classic case is repairing a non-charging dynamo by fitting new brushes.
The manufacturer’s official workshop manuals are written for their trained staff, and so assume special knowledge; detail is left out. This book is written for the owner, and so goes into detail.
The book is divided into twelve Chapters. Each Chapter is divided into numbered sections which are headed in bold type between horizontal lines. Each section consists of serially numbered paragraphs.
There are two types of illustration: (1) Figures which are numbered according to Chapter and sequence of occurrence in that Chapter. (2) Photographs which have a reference number on their caption. All photographs apply to the Chapter in which they occur so that the reference figure pinpoints the pertinent section and paragraph number.
Procedures, once described in the text, are not normally repeated. If it is necessary to refer to another Chapter the reference will be given in Chapter number and section number thus: Chapter 1/16.
If it is considered necessary to refer to a particular paragraph in another Chapter the reference is eg, ‘Chapter 1/5:5’. Cross references given without use of the word ‘Chapter’ apply to sections and/or paragraphs in the same Chapter, eg, ‘see Section 8’ means also ‘in this Chapter’.
When the left or right side of the car is mentioned it is as if looking forward from the drivers seat
