PREFACE

Generally, rollers tend to come large-sized and find their applications in

dangerous fields such as rough terrain, steep slopes or slippery areas. Faulty

rollers may risk a grave accident.

For purpose-built rollers to negotiate problem terrain with the ultimate in

performance maintained free from failure over the longest possible period of

time, adequate handling and regular preventive maintenance recommended

are of prime importance. If a trouble developes, it should be effectively

corrected with proper safety measures taken.

This service manual is intended to serve as a guide particularly for

maintenance personnel to perform quality service by gaining working

knowledge of and reliable maintenance techniques for machines in question.

Included in this literature are descriptions of SPECIFICATIONS, STRUCTURE

& OPERATION, INSPECTION & ADJUSTEMNT, FAULT DIAGNOSIS and

DISASSEMBLY & ASSEMBLY. Systematic explanations are being given to

each of these five cathegories in this sequence.

Rollers principally concern qualitative factors as represented by ‘compaction

density’, to say nothing of quantitative elements like ‘productivity’.

SPECIFICATIONS section includes performance data of major significance

e.g. ‘vibratory frequency’ to be checked when servicing machines in question.

For reasonable maintenance services, it is a precondition to know the vital

portions of machines in question and how they work. Referring to relevant

electric wiring and hydraulic circuit diagrams, STRUCTURE & OPERATION

instructs location of key units and function of systems into which the key units

are assembled.

Adjustment practice to restore a faulty machine to the normal operating state

involves measurement procedure which compares measured figures with the

standard values. INSPECTION & ADJUSTMENT specifies conditions to

measurement and standard values. Safety precautions are also given where

necessary. Illustrations included indicate important points like gauge

connection location.

Numerous ways are available to track down the cause of trouble. Important is,

of course, to make a diagnosis in a reasonable manner, not blindly. FAULT

DIAGNOSIS provides a detailed description of ‘Precautions for Trouble

Diagnosis’ and ‘How to Make a Diagnosis’ first, then proceeds to instruction of

diagnosis procedures on a variety of fault diagnosis modes. For effective fault

finding, this chapter employs block-type flow charts easy to handle. Electric

wiring diagrams used herein identify wires by means of color coding and

identification numbers. Standard values or fault finding conditions are noted

where necessary.

In the final section, DISASSEMBLY & ASSEMBLY, descriptions are being

given of removal, reinstallation, disassembly and reassembly procedures of

key units in this order with many solid illustrations easy to understand in order

to display vital part of units to handle. Because works to be performed in this

cathegory will enevitably have a high potential to invite danger, this section

involves many precautionary statements.

Fully understand the contents of this manual and make the best of it. We will

make utmost efforts to make this manual more useful through revisions. Your

opinions and advices will be particularly welcome and carefully considered.
