Hitachi EH4500 401MDD Construction Truck Parts Catalog Master Book – Wheel Motor & Drivetrain PDF

Description

Hitachi EH4500 401MDD Master Parts Catalog

This is the Master Book parts catalog for the Hitachi EH4500 construction truck built under model designation 401MDD. It is a full parts identification reference published by Hitachi Construction Truck Manufacturing Ltd. of Guelph, Ontario, Canada, and it is organised so that a wheel motor, planetary gear set, rear axle shaft, brake assembly or hydraulic valve can be located by function group, by alphabetical index or by part number. For anyone maintaining or rebuilding an EH4500, this is the document that turns a description into a number you can actually order.

The October 2008 release note states that this edition was issued for production of the new Hitachi part number P8DU-AA-0000-A and supersedes all earlier versions listed above. Serial-number usage is printed at the bottom of individual pages, so a page may apply to a subset of trucks rather than the whole fleet.

How This Parts Catalog Is Organised

The catalog is split into eleven main function groups. Group 1000 holds the systems schematic and the preface material. Groups 2000 through 9000 contain the equipment parts pages and their complementary illustrations. Group 10000 is the option section, where each option sits behind its own title page. Group 11000 is the numerical index in the back of the book, listing every part number printed anywhere in the catalog.

Each function group is divided into subgroups using the ones, tens and hundreds place, with the thousands place staying constant. That is why wheel motor content is found under 4015 and 4630, planetary gearing under 4810 and 4820, and rear axle work under 4600 and 4610. Quantity in the GT column is the quantity required for one machine, while quantities inside a breakdown are the quantity for one assembly. Where the part number is followed by an asterisk, the illustrations carry important notes that should be checked before ordering.

Taken as a whole, the catalog gives a technician or parts interpreter a complete functional map of the EH4500. Rather than a repair narrative, it is a structured identification system: exploded illustrations are paired with text pages so a component can be matched visually, then confirmed by part number, quantity per machine and service code. The alphabetical index and function group index let you enter from a description, while the numerical index lets you enter from a number you already have in hand. For drivetrain work in particular, the coverage runs from the traction motor and wheelmotor spindle assembly through the inner and outer planetary gears, planetary gear sets, ring gear assemblies and rear axle shafts, so a rebuild can be planned at assembly level or at individual component level.

Where This Catalog Is Most Useful

Wheel motor and final drive work is the strongest area of this book. The 4015 and 4630 groups cover the wheelmotor and spindle assemblies, while the 4810 and 4820 groups break the planetary gearing down into 35.8:1 and 40.8:1 ratios, covering inner planetary gear, outer planetary mounting, planetary gear assemblies, planetary gear sets, ring gear assembly and outer ring gear. Rear axle shaft, spindle assembly and rear axle mounting content sits alongside it in the 4600 and 4610 groups.

Brake and steering work is equally well served. Front brake and mounting, wet brake and mounting, brake head nitrile and viton, front brake disc and mounting, brake assembly, brake seal reservoirs and accumulators occupy group 5000, while group 6000 carries the steering column, steer shaft assembly, steer valve, steer cylinder, steer pump, steer filters, flow amplifier valve and RCB and accumulator hardware.

Electrical and control content is extensive, spanning batteries, battery cables, alternator, dual winding alternator, starter motor, shift selector, headlamps and tail lights, horns, chassis electrical front and rear, engine electrical, switch boxes, circuit boards, hoist controller, wire harnesses by location, instrument panels, radio, camera and loadweigh displays. Power transmission control hardware — control cabinet, control panel, grid box, grid box motor, transformers, contactors, circuit breakers, capacitors, inverters, resistors, core assemblies and trolley system components — is grouped under 4000.

Why the Numbers Matter

On a machine of this size, the difference between the correct wheel motor component and a visually similar one is measured in downtime and in the cost of a second teardown. The catalog ties each component to a group, a sequence and a revision, and prints the serial-number usage that applies to the page you are reading. That lets you confirm a part against the actual truck rather than against a general description, which is exactly what you need when a fleet carries several build configurations across the six serial prefixes listed in this book.

Because the book is arranged by function group rather than by repair order, it works equally well for a planned final drive rebuild, a single seal or bearing replacement, a brake accumulator service, a harness repair or a body and hoist component check. You start from the system, find the subgroup, read the illustration, and take the number.
