General instructions

Practical advice

Prior to any work:

– Clean the major unit and its surrounds (See Driving Servicing Handbook, "Vehicle washing"). – Ensure the batteries are disconnected. – Mark the pipes and wiring harnesses, if necessary. – Protect all ports to prevent the ingress of foreign matter. – Before disconnecting an air pipe, drop the circuit pressure. – If liquid is splashed onto the bodywork, clean quick l y with a cl ea nin g pr odu ct rec om men ded by RENAULT

TRUCKS.

Preparation prior to assembly:

Carefully clean and check all the parts. Do not unpack a new bearing until you are ready to install it. Do not clean off the protective grease on new bearings. Old seals and lock-plates must be discarded and new ones fitted. Never force fit parts with copp er or brass punches or drifts. Alway s use a specially adapted driver to prevent ingress of metal particles into the casings and bearings. Always oil parts prior to force fitting. Always apply grease on the inside of seal ring lips. Shrink fitted parts are to be heated with a hot air blower or in an oven. etc. Flame heating is strictly forbidden.

When using a torque multiplier, calibrate the torque wrench/multiplier unit at the required torque loading.

Fastening, locking, sealing and adhesive products:

Prior to assembly, carefully clean the product application surfaces of the parts. Old product residue is to be removed. Threaded portions are to be brushed, tapped and, if necessary, cleaned with a suitable product.

Using the product:

Always adapt the recommended product while observing the utilization conditions appearing on the pack:

– Surface finish, – Working temperature, – Reaction, drying, etc. time, – Shelf life.

Observe the assembly method so as to guarantee the quality of the repair.

Presentation of the gearbox

32 661

A-7

The gearbox consists of 3 main parts.

– The clutch casing (7), which also serves as front wall for the gearbox. – The basic gearbox casing (13), which contains the primary shaft, the secondary shaft, the countershaft, the

reverse shaft, the selector mechanism integrated in the transmission control unit, together with the range change and the splitter.

– The range change casing (3), which contains the epicyclic gear train for the range change and the output

shaft (10).

The principal gearbox parts are:

– Primary shaft (8), – Secondary shaft (9), – Range change (10), with selector mechanism (4), – Intermediate shaft (11), with disc brake (6), – Reverse shaft (12), with oil pump drive shaft (5),

– Transmission control unit (1), with gear change mechanism. The countershaft and reverse shaft gears and all the basic gears are on the secondary shaft, with the range change sun gear on the secondary shaft. The countershaft gears are fixed. The range change, which consists of an epicyclic gear train forms integral part of the output shaft. The oil pump drive shaft forms integral part of the reverse shaft.

RENAULT TRUCKS 10/2004

32 661

Transmission control unit

The transmission control unit is located above the gearbox.

The gears are selected by means of the gear selector. When a gear is selected, the system first of all reduces the engine torque to an acceptable level and the gearbox is put into neutral. When the gearbox is in neu tral, t he e ngi ne s pe ed i s adjus ted s o a s to choose the correc t engine speed for the gear se lected and the gear is then engaged. The control unit casing cover serves to house the following components:

– 3 electrical connections,

– 1 transmission control unit (TECU),

– 9 solenoid valves,

– 1 pressure sensor.

The control unit casing cover includes 3 electrical connections:

– I: vehicle communication ,

– II: retarder,

– III: clutch.

The control unit casing cover serves to house 9 solenoid valves:

– 1: solenoid valve 1

– 2: solenoid valve 2

– 3: solenoid valve 3

– R: reverse solenoid valve

– B: disc brake solenoid valve,

– LR: low range solenoid valve,

Countershaft disc brake

The countershaft disc brake is placed at the front of the gearbox, on the end of the countershaft. It is designed to brake gearbox rotating components when a moving off gear is activated. This device serves to eliminate wear, noise and fr iction in the gear box. The dis c brak e is activated by an built-in air-operated ram.

The gearbox is lub ri cated by a co mbi na tio n of splash (for th e coun ter s haft and th e r ever s e s haf t) and by an oi l pump (A) (for the primary shaft, the secondary shaft and the range change). An oil filter (B), of the cartridge type, is fitted on the delivery side of the oil pump. It is located on the filter housing and is accessible from the outside. The filter is protected by a cover located on the range change casing. The oil is delivered to the secondary shaft to lubricate and cool the range change gears as well as the primary shaft and secondary shaft bearings.

Tightening torques

Definitions

Tightening torques

There are several types of tightening:

– Tightening to torque (in Nm) – Tightening to angle (in °)

– Tightening to torque-angle (in Nm + °) Torq ues gi ven in Nm are nominal torques (average value calculated on the basis of the minimum torque and the maximum torque). The tightening precision class defines the tolerance of this torque in percent as a function of the nominal torque applied. For standard threaded hardware, use the following table. For other torques, see the following page(s).

"FIH" type (Nylstop) locknuts must be replaced whenever removed. "DRH" type (oval) locknuts can be reused. If locknuts (DRH, FIH or other) are re-used, make absolutely certain that the screw-thread of the bolt protrudes least two threads above the top edge of the nut.

RENAULT TRUCKS 10/2004

B2-2

32 661

Standard nut and bolt tightening torques table

The tightening torque values given in the table are based on standard 01.50.4002 and apply to new nuts and bolts fitted dry and re-used nuts and bolts with oil applied to the screw-threads. If any nuts and bolts are replaced, it is

absolutely essential to use nuts and bolts recommended by th e RENAULT TRUCKS Spare Parts Departmen t (coefficient of friction in compliance with standard 01.50.4002).
