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.
