Description

Komatsu D375A-5 Bulldozer Parts Book Manual S/N 18001 and Up

This is the full illustrated parts book for the Komatsu D375A-5 crawler dozer built from machine serial number 18001 onward, prepared around the SA6D170E-3A-7 engine from engine serial number 310043 up. Across 650 pages it walks the machine group by group, pairing a drawing of each assembly with the part numbers, part names, quantities and serial-number applicability that belong to it. If you have ever had a D375A-5 down while someone guessed at a bushing size or a bolt length, this is the document that removes the guesswork.

How the Pages Are Laid Out

Every parts page in this D375A-5 parts book follows the same two-panel arrangement. The left side carries the exploded or assembled drawing with numbered balloons pointing at each component. The right side carries the matching table: Item, Part No., Part Name, Qty and Serial No. The serial column is the one that matters most on a machine of this age, because a great many D375A-5 assemblies changed partway through the 18001-up run, and the table prints both the superseded number and its cut-off range directly underneath the current one.

Each page also carries a reference code such as B0100-01A0 or F2200-01A0 together with a six-digit page number like 030010 or 150010. Those codes are what let you jump between a group index and the drawing you actually want, and they are what a parts counter will ask you for when you call an order in.

Chapters Covered

The book is divided into fifteen lettered groups. Below is what each one holds:

Taken together, those fifteen groups give a technician something a service manual alone cannot: the exact identity of every replaceable item on the machine, in the correct quantity, tied to the correct serial band. The 632 illustrated parts pages are where the real value sits, and the group indexes at the front of each section are what get you to them quickly.

Serial Number Breaks You Will Meet

One of the more useful things about the Komatsu D375A-5 parts book for S/N 18001 and up is how openly it handles running changes. Rather than quietly listing only the latest part, the tables stack the alternatives with their serial windows. The muffler, for example, appears in four successive versions across 18001-18009, 18010-18018, 18019-18402 and 18403 onward. Blade lift line splits at 18013. Cab glass changes at 18102. Ripper lift and tilt cylinders change at 18152. Semi-U and full-U blades change at 18629. Blade and ripper identification plates begin at 18719. Fusible links change at 18364. Condenser assemblies change at 18066.

Knowing your machine number before you open the book is therefore the first step, and once you have it, the tables do the rest of the work for you.

Optional and Regional Configurations

The D375A-5 was sold in a long list of build combinations, and this parts book carries them all rather than assuming a single standard machine. Cushion dozer, tilt dozer and dual tilt pitch dozer front ends are covered separately. Multi ripper and giant ripper rear ends each get their own beam, arm, cylinder and piping sheets. Cold weather (A) specification appears through the undercarriage, the power train tank and the coolant and oil pan heater. Noise suppression specification for EU shows up in the guard and accessory groups. Saudi, MSHA, KA, EC, Japan and EU market variants appear where the hardware genuinely differs. VHMS and the VHMS kit run through the electrical, floor and dashboard sheets. If your machine has shoe slip control, a dust indicator, an air conditioner, an additional heater or a heavy duty harness, there is a separate illustration for it.

Order the Right Part the First Time

With the Komatsu D375A-5 bulldozer parts book manual for S/N 18001 and up in front of you, you can build an accurate parts list for a final drive rebuild, a transmission or torque converter overhaul, an undercarriage change, a blade or ripper repair, a cab or dashboard repair, a cooling system refresh or a hydraulic line replacement without a single phone call spent describing a component you cannot name. You can check quantities before you order, so a job does not stop for four washers. You can confirm whether the part your supplier is quoting actually applies to your serial number, which is where most costly mistakes on a machine this old are made. And when a component has been superseded, you can see the older number too, which is often the difference between finding the piece on a used or aftermarket shelf and giving up on it.

Wrong part numbers cost money twice over: once at the counter and once in downtime while the correct piece is chased. A parts book tied to the exact model and serial range removes that risk in a way that generic cross-reference sites cannot. This one covers a 650-page scope on a single machine family, so whatever you are pulling apart on a D375A-5, the answer is already printed somewhere in it.
