Chapter 3 Transmission and final drive

Greg Hudock Brooklands Books ePub

Note. The gearbox is filled for life, i.e. no regular oil changes are necessary. The oil level should, however, be checked at regular intervals.

A new five-speed transmission, type 02B has replaced the previously fitted transmission type 02A in models with 1.9 and 2.4 litre engine. The cable gearchange mechanism fitted to earlier T4 models has now been replaced by a linkage and rod mechanism. A modified transmission, type 02G, also with linkage and rod gearchange mechanism, is used in models with 2.5 litre TDI engine. The transmission and final drive are contained within one housing and thus dismantling and servicing procedures on one can only be carried out with some disturbance of the other.

Chapter 9 Brakes

Greg Hudock Brooklands Books ePub

Disc brakes are fitted to the front wheels of all models, but different brake calipers are used in vehicles covered in this manual. In the vehicle data plate you will find a code, commencing with “1L”', with an additional letter behind. The code refer to the fitted disc brakes and can be interpreted as follows:

Ventilated brake discs are used, but there are different brake disc thicknesses and diameters, depending on the fitted engine. For convenience, all brake systems are covered, irrespective if they are fitted to diesel models or not.

The rear wheels have disc brakes. A dual-line brake circuit is employed. A brake servo unit is standard fitting. A separate vacuum pump is used to feed the vacuum system for the brake servo unit. There is a brake pressure regulator fitted to some models only. Most models are fitted with an ABS system, which for reasons of road safety should not be tampered with.

The master cylinder cannot be repaired or overhauled and must be replaced as a complete unit if faulty.
