The Komatsu PC01‑1 Mini Excavator isn’t just a compact machine—it’s a micro marvel of Japanese engineering. Often called the “thumb excavator”, the Komatsu PC01 can go where no other excavator can—through regular doorways, small gates, and even inside buildings or elevators. If you’ve ever wondered how a true micro excavator performs delicate digging in tight spaces, the PC01 Komatsu proves that big doesn’t always mean powerful—efficiency and design do.
But such unique engineering also means it requires precise care. Using incorrect components can reduce efficiency, compromise safety, or lead to costly downtime. Understanding your Komatsu PC01 specs is the first step toward ordering the right OEM or aftermarket replacements confidently.
This guide breaks down the Komatsu PC01‑1 mini excavator specifications, dimensions, and parts relationships so you can maintain it like a pro. Whether you’re performing routine maintenance or a full rebuild, use this as your complete Komatsu PC01 lookup resource.
Komatsu PC01‑1 Core Specifications
Understanding the machine’s operational and engine specs ensures you source only compatible parts—whether from Komatsu OEM or reliable aftermarket FridayParts options.
Operational & Fluid Capacities
| Specification | Value | Why It Matters for Parts Selection |
|---|---|---|
| Operating Weight | 837.8 lb | Determines the correct undercarriage rating—critical when selecting PC01 Komatsu tracks. |
| Fuel Capacity | 1.2 gal | Plan fuel runtime and proper fuel filter replacement intervals. |
| Hydraulic System Fluid Capacity | 1.3 gal | Helps you buy enough hydraulic fluid and seals after servicing the system. |
Engine Specifications
The PC01‑1 runs on a Honda GX160KI engine. Always match your replacement parts exactly to this model.
| Specification | Value | Why It Matters |
|---|---|---|
| Engine Make | Honda | Always verify sourcing from a trusted supplier like FridayParts. |
| Engine Model | GX160KI | Critical for ordering compatible starter motors / rebuild kits / oil filters. |
| Gross Power | 3.5 hp @ 3000 rpm | Confirms the correct power range when comparing performance. |
| Displacement | 10 cu in | Helps verify internal engine component compatibility. |
Hydraulic and Swing System
The hydraulic components are the PC01‑1’s muscle. Pressure and flow define how strongly and smoothly your compact machine digs.
| Specification | Value | Why It Matters |
|---|---|---|
| System Relief Valve Pressure | 2130 psi | Hydraulic seals & hoses must handle this. For best results, use Komatsu PC01 aftermarket seal kits from FridayParts, rated for OEM pressure. |
| Pump Flow Capacity | 2.7 gal/min | Diagnose pump wear or filter clogs effectively. |
| Swing Speed | 7 rpm | Connected to your swing motor performance & sealing integrity. |
Dimensions & Working Range

These dimensions decide both the working ability and which structural or track components fit perfectly.
Overall Machine Dimensions
| Dimension | Value | Why It Matters |
|---|---|---|
| A — Shipping Length | 6.89 ft | For transport or storage planning. |
| B — Width (Outside of Tracks) | 1.91 ft | This ultra‑narrow width makes the Komatsu mini excavator PC01 ideal for indoor projects or garden work. |
| H — Tail Swing Radius | 2.14 ft | Important for tight space maneuvering. |
| E — Ground Clearance | 0.33 ft | Impacts surface stability and clearance over obstacles. |
Undercarriage Dimensions
| Dimension | Value | Why It Matters |
|---|---|---|
| N — Shoe Size (Track Width) | 5.12 in | Crucial when ordering replacement rubber tracks for the Komatsu PC01. |
| F — Track Gauge | 1.48 ft | Ensures proper track alignment & fitment. |
| D — Length of Track on Ground | 2.14 ft | Affects traction and load stability. |
| Ground Pressure | 2.4 psi | Gives excellent mobility on soft or delicate surfaces. |
| Max Travel Speed | 0.87 mph | The travel motor and final drive components directly influence this. |
Digging Dimensions & Attachments
| Dimension | Value | Why It Matters |
|---|---|---|
| M — Max Digging Depth | 3.45 ft | Defines cylinder spec range for hydraulic repair kits. |
| I — Max Cutting Height | 6.07 ft | This is the performance limit of your boom and stick. If you experience reduced height, it could indicate issues with hydraulic cylinder seals or low hydraulic pressure. |
| J — Max Loading Height | 4.27 ft | Crucial for job planning. Use this spec to confirm if the PC01-1 can clear the side of the truck or container you need to load. |
| K — Max Reach Along Ground | 6.32 ft | Helpful for arm or bucket size reference. |
| L — Max Vertical Wall Dig Depth | 2.3 ft | Indicates reach in tight digging spots. |
| Reference Bucket Capacity | 0.1 yd³ | Use this as a primary reference when ordering a complete replacement bucket. For ordering bucket teeth, you will need the specific tooth part number or style compatible with your bucket. |
