TO  THE  READER

This Workshop Manual has been prepared to provide servicing personnel with

information on the mechanism, service and maintenance of V3300-E2B, V3300-T-E2B.
It is divided into three parts, “General”, “Mechanism” and “Servicing”.

General
Information on the engine identification, the general precautions, maintenance check

list, check and maintenance and special tools are described.

Mechanism
Information on the construction and function are included.  This part should be

understood before proceeding with troubleshooting, disassembling and servicing.

Refer to Diesel Engine Mechanism Workshop Manual (Code No. 9Y021-01870) for

the one which has not been described to this workshop manual.

Servicing
Information on the troubleshooting, servicing specification lists, tightening torque,

checking and adjusting, disassembling and assembling, and servicing which cover
procedures, precautions, factory specifications and allowable limits.

All information illustrations and specifications contained in this manual are based on

the latest product information available at the time of publication.

The right is reserved to make changes in all information at any time without notice.
Due to covering many models of this manual, information or picture being used have

not been specified as one model.
