Foreword

T echnical Information

This manual has been produced a new technical information This new system designed deliver nical information electronically through - ROM and paper manuals. A coding system called Integrated Coding Environment (ICE) has been developed link the technical information other Product Support functions W ranty

T echnical information written support the maintenance and service the functions systems the customer ’ s When a customer has a concern his usually because a function system his machine not working not working ficiently , not responding correctly his When you refer the technical information this manual resolve that customer ’ s you will find all the information classified using the new ICE coding, according the functions systems that machine. Once you have located the technical information for that function you will find all the electrical hydraulic assemblies and sub assemblies for that function Y will also find all the types information that have been written for that function system, the technical data (specifications), the functional data (how works), the diagnostic data (fault codes and troubleshooting) and the service data install integrating this new ICE coding into technical information, you will able search and retrieve just the right piece technical information you need resolve that customers concern his This made possible attaching 3 categories each piece technical information during the authoring

The first category the the second category the Information T ype and the third category the Product:

• LOCA TION - the component function the that the piece technical information going describe Fuel

• INFORMA TION TYPE - the piece technical information that has been written for a particular component function the machine e.g. Capacity would a type T echnical Data that would describe the amount fuel held the Fuel

• PRODUCT - the model that the piece technical information written for .

Every piece technical information will have those 3 categories attached Y will able use any combination those categories find the right piece technical information you need resolve that customers concern his

That information could be:

• the description how remove the cylinder head

• a table specifications for a hydraulic pump

• a fault code

• a troubleshooting table

• a special tool

INTRODUCTION

How Use this Manual

SHIMMING

For each adjustment select adjusting shims and measure individually using a micrometer , then add the recorded values. not rely measuring the entire shimming set, which may incorrect, the rated value indicated each

ROT A TING SHAFT SEALS

For correct rotating shaft seal proceed follows:

• before assembly , allow the seal soak the oil will sealing for least thirty minutes

• thoroughly clean the shaft and check that the working surface the shaft not damaged

• position the sealing lip facing the fluid; with hydrodynamic take into consideration the shaft rotation direction and position the grooves that they will deviate the fluid towards the inner side the seal

• coat the sealing lip with a thin layer lubricant (use oil rather than grease) and fill the gap between the sealing lip and the dust lip double lip seals with grease

• insert the seal its seat and press down using a flat not tap the seal with a hammer mallet

• whilst inserting the seal, check that perpendicular the seat; once settled, make sure that makes contact with the thrust required

• prevent damaging the seal lip the shaft, position a protective guard during installation operations

O - RING SEALS

Lubricate the O - RING seals before inserting them the seats, this will prevent them from overturning and twisting, which would jeopardise sealing ficiency

SEALING COMPOUNDS

Apply one the following sealing compounds the mating surfaces marked with R SILMA RHODORSIL CAF 1 LOCTITE PLASTIC GASKET Before applying the sealing prepare the surfaces follows:

• remove any incrustations using a metal brush

Never make break any the charging circuit including the battery when the engine

Never short any the charging components ground.

Always disconnect the ground cable from the battery before arc welding the combine any header attached the

• position the welder ground clamp close the welding area possible

• welding close proximity a computer then the module should removed from the combine

• never allow welding cables lay near across any electrical wiring electronic component while welding progress

Always disconnect the negative cable from the battery when charging the battery the combine with a battery charger

NOTICE: welding must performed the either the combine the header (if the battery ground cable must disconnected from the combine battery . The electronic monitoring system and charging system will damaged this not

Remove the battery ground cable. Reconnect the cable when welding completed.
