Jag MK2

MK2 Cruise Control

Rostra Cruise Control  Components I installed an Audiovox CCS-100 Cruise Control system on my Healey and found it to be a useful modification. I am over six feet tall and the seating position in British cars can be uncomfortable on long drives. The cruise control makes those trips a bit more relaxing and enjoyable.  Rostra […]

Jaguar Electrical Components

In this entry I will identify some, but not all of the major electrical components in the MK2, that are not addressed in their own entry or post. Electrical System Overview The Jaguar MK2 being British and a product of the mid-sixties has a positive earth electrical system. The starting system utilized a battery mounted […]


Handbrake Calipers

 Handbrake Handbrake Calipers The mechanical handbrake unit is mounted on and above the caliper bodies on the rear brakes by means of pivot bolts and forked retraction plates. The Jaguar Service Manual states: “The handbrakes are self-adjusting to compensate for friction pad wear and automatically provide the necessary clearance between the brake discs and the […]

Brakes MK2

The Front and Rear Brakes The Jaguar MK2 uses a single line hydraulic system actuating disc brakes in both the front and rear of the car. While the four wheel disc brakes were “cutting edge” at the time of production for a four-door sedan, today, the braking action can be upgraded with vendor supplied modification kits. […]

Gearbox, Clutch and Propshaft

Clutch and Gearbox Clutch Master Cylinder I will replace the master and reservoir seen here with a new unit. Since the clutch master and the brake master share the same housing and pedal box, information about those components is addressed under the brake servo and hydraulics post at this link: http://valvechatter.us/?cat=615 Bracket for Flexible Clutch Hose […]

Gauges, Instruments and Switches

Gauges, Instruments and Switches Smiths and Lucas Lucas was the primary provider of things electric incorporated in the Jaguar MK2 and for that matter most other British cars of the period. Smiths, another British automotive parts manufacturer produced instruments/gauges, heaters, clocks and radios among other components. Eric Kriss, a fellow MK2 restorer, has an excellent […]

MK2 Lubricants and Fluids

MK2 Lubricants and Fluids I will summarize the capacities and type of fluids I used in the MK2 as I rebuild the car. Additional detail may be available in the web site entry related to the specific lubricant. For example, the rear axle/differential lubricants are detailed in the rear suspension post: http://valvechatter.us/?p=3826 Rear axle/Differential – 4 […]

Rear Suspension

Front & Center Leaf Spring Mounting Plates

Rear Suspension The MK2 rear suspension is a live axle leaf spring design utilizing bonded rubber bushings and pads. Torque arms with bonded rubber bushes at each end fit between brackets welded to the top of the axle and to a body cross-member at the back of the rear seat panel. Lateral location of the […]

Battery Relocation to the Boot

Battery Relocation to the Boot Installing the RetroAir air conditioning kit requires the relocation of the battery, and the most commonly used place is the shelf in the MK2 boot. The RetroAir kit provided a plastic battery box, battery cable and various connectors, but I chose to “upgrade” the kits components. Battery Cable Lugs First […]

Steering Wheel

Steering Wheel   This is a diagram showing steering column components. The disassembly procedure I followed is outlined below: First I removed four slotted set screws from behind the steering wheel this enables the horn ring cover to be removed along with the horn push and return spring. The horn ring assembly is held in […]

New Wiring Harness Circuits

Power Inputs to the Classic Technologies’ Relay/Fuse Panel The Classic Technologies Panel has four primary connections. A – 12V power input from the small fuse box (battery B+) to power the accessories circuits. A brown 12 AWG wire is used to the Yellow screw terminal spade lug connection. B – 12V power input from the […]


Rear View Mirror The parts manual does not provide much information on the rear view mirror. The assembly apparently came from Lucas and was installed as an assembly. Perhaps there is Lucas documentation available someplace, but I did not find it. My original mirror was pretty dirty and the height adjustment post would not tighten […]

Engine Mounting

Engine Mounting Rear Engine Stabiliser The rear of the engine is attached to the firewall (dash) of the car via a stabilising link with a rubber bushing and a rear mount on the firewall with a rubber bushing. I cleaned both components and installed new bushings. The rubber mounting for the stabiliser link needed to […]

Accelerator Controls

Accelerator Pedal Assembly

Accelerator Pedal Assembly The accelerator pedal assembly was in good shape. I replaced the rubber pad on the accelerator pedal with a new one. I left the set screw restricting the pedal travel as it was found, as well as the two felt washers located at each side of the pedal boss. The bracket assembly […]

Scuttle Ventilator

 Scuttle Ventilator Assembly Ventilator Concept My fellow MK2 restorer Eric Kriss has a very nice diagram and explanation of its workings on his Blog. With all credit to Eric, this is an excerpt from his post on the topic:           “The beloved Jaguar scuttle ventilator, probably designed by Rube Goldberg himself, […]

New Wiring Harness Planning & Prep

After selecting the fuse/relay panel from Classic Technologies to be the heart of my new electrical system, the next issue was to decide about the wiring harness to be used. I could either select a pre-assembled harness from one of a number of vendors, knowing that I would have to modify it given the “personalizations” […]

New Wiring for Switches and Gauges

The diagrams provided below depict the wiring to/from each of the switches in the panel. The purpose, operation and in some cases repurposing of the switches is described in a previous post “Gauges, Instruments and Switches.” One addition to the panel is a small chime that is activated if the headlamps are left on when the ignition […]

Interior Lights

Conversion to LED lights The Jaguar Mk2 and all other cars of the period used incandescent bulbs in the interior fixtures and gauges. In my restoration I intend to replace most if not all incandescent lights with light emitting diodes or as they are more commonly referred to: LEDs.  LEDs live longer, use considerably less power, […]

Exterior Lights

Headlamps Cars exported to the USA all had sealed beam headlights. Mounting and Adjusting Screws Four #10 – 32 x 1/2″ slotted cheese head screws with flat and shakeproof washers fasten the lamp assembly to the car’s body. The rubber seal is located between the body and the lamp bowl. Their location is shown in […]

Bonnet Catch/Latch

Bonnet Catch/Latch Control Wire, Complete, Operating Bonnet Lock My original control wire plastic cable casing was in pretty bad shape so I replaced it with a new one from SNG Barratt. It is very close to the original although the cable casing did have to be trimmed a few inches.  I cleaned up the components […]

Classic Technologies Relay/Fuse Panel

Wiring System Upgrade The Fuse/Relay Panel The heart of the original Jaguar MK2 electrical system was a fuse panel assembly located on the LH engine bay valance under the bonnet. The fuse panel bracket assembly houses the RB310 Voltage Control Box (Regulator), the Fuse Box unit, and the Horn Relay. It has a metal top protecting the internal […]

Radiomobile Radio, Aerial and Housing

Radiomobile Radio Housing and Aerial Radiomobile Aerial The aerial height on my Mk2 was controlled by a hand crank and cables. The hand crank was located below the steering wheel through the finisher panel. I was going to forgo the use of the aerial since my aerial was broken, but Robert Seligman (also restoring a […]

Body Panels and Trim

Steering Wheel Shaft & Dip Switch Blanking Plates

Body Panels and Trim Cover and Blanking Plates Of course, there are many large and small components that comprise the finished body of the MK2. The clean-up and preparation of the body and its primary parts is addressed in the “Body Prep” post. However, I have also begun to prepare some of the smaller components […]
