Caterham 420 Workshop Manual

Jacking

Before jacking your Caterham, make sure you’re familiar with the jack you’re using. Ensure you know how to slowly lower the jack in a controlled manner. This is especially important when lowering a Caterham onto axle stands.

A light-weight aluminium trolly jack is more than strong enough for jacking a Caterham and has the advantage of being light when manoeuvring it around the garage.

WARNING – Never work under a Caterham only supported by a jack. Always support the Caterham on Axle Stands.

Front

REMINDER – If you intend to remove the front wheels, loosen the wheel nuts before jacking.

On the advice of a well known Caterham race team, jacking the front of the car is done using the front towing eye located on the right-hand side near the nose cone. To protect the powder coat on the towing eye during jacking, a jack pad with a groove is used. These are often used when the car is designed to be jacked on the sills.

Fit the jack pad onto the towing eye and position the jack. Ensure the jack pad and jack are centred before lifting. Positioning the jack at a slight angle to the car helps when positioning axle stands under the front of the car.

Using this lifting location will lift the Caterham slightly higher on the right hand side, but this will level when the Caterham is lowered onto axle stands.

Rear

IMPORTANT – If the front wheels are still on the ground, use a wheel chock on the front wheels to prevent the Caterham from moving when the rear wheels are lifted.

The rear of a Caterham 420R is lifted using the centre of the DeDion tube. To prevent damage to the A-Frame or the DeDion tube powder-coat ensure the raised sections of the jack cup don’t come into contact with the A-Frame. Old carpet is a fantastic way to protect powder coating during jacking.
