Komatsu TURBOCHARGER, AIR COMPRESSOR, PE(S) A TYPE, PE(S) P TYPE, KFE TYPE 2001 Workshop Manual

You’ve got a Komatsu engine on the stand, turbocharger leaking oil, air compressor not building pressure, or a fuel injection pump that’s acting up. Without the right spec sheet, you’re guessing. Guessing on a turbocharger assembly costs you a rotor. Guessing on injection pump timing costs you a whole engine. This 2001 Komatsu TURBOCHARGER, AIR COMPRESSOR, PE(S) A TYPE, PE(S) P TYPE, KFE TYPE 2001 Workshop Manual is the factory document that stops the guesswork. 648 pages of procedures, torque values, and inspection standards that Komatsu wrote for their own techs. I’ve been turning wrenches for 28 years, and I wouldn’t touch a fuel system without this kind of backup.

Turbocharger Disassembly and Assembly: What the Factory Manual Shows

Starting with the turbo section, the manual breaks down the KTR100, KTR110, KTR130, and KTR150 models. You get the structure and function diagrams, then the disassembly steps. The assembly section includes the torque sequence for the turbine housing bolts. Page 2 of the turbocharger chapter lists the tightening torque for the compressor wheel nut – that’s a spec you don’t want to guess on. Over-torque it and you crush the thrust bearing. Under-torque it and the wheel walks off the shaft at 80,000 rpm. The manual also includes a maintenance standard table with wear limits for the shaft and bearings. That’s the kind of data that keeps a turbo from coming back on a warranty claim.

Air Compressor Performance Test and Tightening Torque

Air compressor section covers the 6206-91-1100 series through the 6165-91-1005 series – that’s a lot of variations. Each series has its own disassembly and assembly procedure with the correct tightening torque for the cylinder head bolts and the unloader valve. There’s a dedicated performance test on page 12 of the air compressor chapter. You hook up a pressure gauge, run the engine at rated speed, and check the output against the table. If the pressure doesn’t match, you know the rings or valves are worn. The manual also explains the operation of the unloader valve – that’s the part that causes most air compressor complaints but gets overlooked because nobody reads the function description.

Fuel Injection Pump PE(S)-A Type: Adjustments and Precautions

Fuel injection pump section is the thickest part of the manual. It covers the PE(S)-A type, PE(S)-P type, and KFE type. For the A type, you get the injection timing adjustment procedure, the control rack “0” position setting, and the injection quantity adjustment. Each adjustment references a specific special tool – the manual lists the part numbers for the setting fixtures and gauges. Don’t try to improvise a tool; the manual tells you exactly what to use. The precautions section is worth reading alone: it covers fuel oil specifications, bleeding the fuel system, and lubrication procedure. I’ve seen techs skip the bleeding step and then wonder why the pump won’t prime. The manual has a troubleshooting table that links symptoms to causes – no scrolling through forum posts.

Standard Tightening Torque: Why You Need the Factory Page

Every Komatsu shop manual includes a standard tightening torque table in the foreword. This one covers the standard bolts and nuts used across the engine. The table lists torque in ft-lb for bolt grades and sizes. That table is your baseline for any fastener that doesn’t have a specific torque in the procedure. Ignore it and you’re working blind. The manual also includes the electric wire code and conversion table – useful when you’re dealing with metric threads and need to convert to imperial. I keep a copy of that table laminated on my bench.

3 Reasons to Trust OEM Documentation Over Aftermarket Reprints

First, the OEM manual has the original safety notices from Komatsu. The foreword opens with a safety section that covers proper lifting, welding precautions, and personal protective equipment. Aftermarket reprints often cut those pages to save paper. Second, the torque values in this manual are the ones Komatsu used on the production line – not a generic spec from a third-party database. Third, the part numbers for special tools are correct. If you order tool 6162-83-6700 based on the manual, it will actually fit the S6D170-1 series air compressor. Try that with a scanned copy from a forum.

The Komatsu WH609-1E0 WH613-1E0 WH713-1E0 WH714H-1E0 WH716-1E0 Workshop Manual covers the hydraulic excavator side. And the Komatsu PW95R-2 Workshop Manual – 520 Pages of Factory Specs is a good companion for the engine components covered here.

If you need background on how an Air Conditioning Compressor works, Wikipedia has a solid overview. For Manual Transmission repair, we have other OEM manuals; this one focuses on the engine components.

Does this manual include torque specs for the air compressor?

Yes, page 2 of the air compressor section has a dedicated tightening torque table.

What models are covered in the fuel injection pump section?

PE(S)-A type, PE(S)-P type, and KFE type. The manual covers disassembly, assembly, adjustment, and troubleshooting for each. It includes exploded views, special tool lists, and injection timing aligning marks. The PE(S)-A type section alone has over 100 pages of detailed procedures.

Is this the original OEM manual or a reprint?

This is the original factory PDF from Komatsu. It’s not a third-party scan. The safety notices and part numbers are untouched.

How many pages is the manual?

648 pages.

This manual belongs on your hard drive and on your tablet in the shop. The factory procedures for the turbocharger, air compressor, and fuel injection pumps are laid out in the order you’d actually work. No reorganized sections, no missing torque values.
