Komatsu PC130-6K, PC150LGP-6K 2001 Workshop Manual

If you’re tearing down a PC130-6K or PC150LGP-6K without the factory manual, you’re gambling with your time and the customer’s machine. I’ve seen guys strip threads on the final drive because they guessed the torque. Don’t be that guy. The Komatsu PC130-6K, PC150LGP-6K 2001 Workshop Manual gives you the exact numbers and sequences Komatsu engineers signed off on. 730 pages of raw data, not some aftermarket translation where they round off 236 Nm to 170 ft-lbs and call it close enough.

Keep your torque wrench calibrated.

Structure and Function: How the Machine Is Built

This section (starting on page 10-1) walks through every hydraulic circuit, gear train, and control linkage. You’ll see exploded views of the swing motor, travel assembly, and the SA4D102E engine interface. The manual doesn’t assume you know which line is which — it labels each component with Komatsu part numbers. When you order a seal kit, you match the number in the book, not the one on the used part that may have been swapped years ago. The structure section alone saves you from chasing wrong parts.

Testing and Adjusting: Where Most Guys Mess Up

I’ve seen a lot of field fixes that turned into rebuilds because someone skipped the adjustment procedure. The Testing and Adjusting chapter (page 20-1) lists every pressure tap location and spec. Need the charge pressure? It’s in there. Need the pilot pressure? Same page. The manual gives you the sequence: warm the oil, install the gauge, cycle the function, read the value. No shortcuts. If you don’t have this, you’re guessing whether the relief valve is set right or the pump is worn. This is where the manual earns its keep.

What Serial Numbers Are Covered?

PC130-6K models from K30001 up and PC150LGP-6K models from K35001 up. The manual explicitly lists these ranges on page 00-1. If your machine falls outside that range, some revisions may differ. Komatsu issued a LIST OF REVISED PAGES that tells you exactly which pages to replace or add. That system is in the front of the manual — pay attention to the marks: a dagger (†) means replace, an arrow (→) means add. I’ve had techs ignore those and then wonder why a clearance spec was off by 0.5 mm. Follow the revision list.

730 Pages of Factory Data

Seven hundred and thirty pages cover the entire machine. Not just the engine or hydraulics — the whole chassis. The Disassembly and Assembly section (page 30-1) gives step‑by‑step sequences with tool callouts. You need the special puller for the final drive? The manual lists Komatsu tool numbers. The Maintenance Standard section (page 40-1) contains the wear limits and tolerances for every bushing, pin, and seal. Want to know when to replace a track bushing? The dimension is right there. Having this on your tablet or printed out means you stop guessing and start measuring.

Check the List of Revised Pages

The manual includes a formal change control system. Each revised page has a mark — insert, replace, or delete. This is real OEM practice, not a static PDF that’s missing updates. The list starts on page 00-2-1 and runs through all serial number ranges. If your machine is from a later production series, you need the revised pages to match the as‑built specs. The manual we sell is the complete file including all revisions up to publication. No aftermarket housekeeping — just the raw factory sheets.

Why the OEM Print Matters

Aftermarket manuals for Komatsu machines are a gamble. I’ve tested three different ones and found wrong torque values for the swing gear bolts. The OEM version — this one — comes from Komatsu’s own documentation system. It’s the same book dealership techs use. The Structural and Function diagrams are taken from the actual CAD data, not redrawn by a third party. If you want to avoid a blown seal because the wrong preload was spec’d, stick with the factory source. That’s what this 2001 manual delivers.

Related manuals you might need: the Komatsu PC130-6K PC150LGP-6K 2001 Workshop Manual itself, plus the Komatsu PC130-6K PC150LGP-6K Operators Manual – Factory OEM Specs for daily operation, and the Komatsu WA65-5 WA70-5 WA80-5 2005 Workshop Manual if you service wheel loaders.

The travel drive on these machines uses a planetary reduction that’s essentially a Manual Transmission assembly. Understanding the basics of a Manual Transmission helps when diagnosing gear noise or shift issues.

Does this manual cover the SA4D102E engine?

Yes, but engine-specific repairs are in a separate manual.

What serial numbers are included?

PC130-6K from K30001 up and PC150LGP-6K from K35001 up. These are clearly listed on page 00-1.

Is this a digital download or a physical book?

This is a digital PDF download. You get the full 730-page factory manual in searchable format. Downloaded immediately after purchase.

Can I use this manual for the PC150LGP-6K with a different engine?

The manual covers both models as built. If the machine has been repowered with a non-Komatsu engine, the electrical diagrams and mounting specs won’t match. The manual is designed for the original SA4D102E diesel. Do not assume aftermarket modifications are documented. Stick with factory configuration. The manual includes a list of revised pages and a replacement system. If your machine serial number falls within the range, the data applies. However, modifications after delivery are not covered. Always verify with your local Komatsu distributor for attachments or optional equipment that may differ. The manual itself has a revision list to ensure you have the correct pages for your serial number range. That is detailed on the LIST OF REVISED PAGES section. I’ve seen guys try to use the wrong revision and wonder why a clearance spec is off. Pay attention to those revision marks.
