RITO HYDRAULIC supplies this complete assembly — net weight 162 kg — with OEM-parameter fit for easy installation and high replacement precision. Key characteristics: responsive electronic ...

Quick Answer The Komatsu PC40MR-2 and PC50MR-2 mini excavators use the same compact, load-sensing variable hydraulic pump — but that one pump is listed under several Komatsu part numbers (708-3S-00462, 708-3S-00522, 708-3S-00872, 708-3S-00461 and 708-3S-00870). Net weight is about 33.93 kg. This guide explains how the numbers relate, and how to confirm which one your machine actually needs b...

Quick Answer The Komatsu PC210-7K (20-ton class) runs the main pump referenced as 708-2L-00202 (alternates: 708-2L-00200, 708-2L-00203), net weight about 181.6 kg. It uses a variable plunger, load-sensing structure for precise control and strong digging power. This guide helps you answer the real question: is the pump actually failing, or is something else in the circuit? — then how to confi...

Quick Answer This page is a quick reference for the main hydraulic pump assembly on the Komatsu PC200-7 and PC220LC-7 excavators. The assembly is a twin (tandem) variable-displacement axial-piston pump — two pumping sections in one housing — ordered under 708-2L-31123 or 708-2L-00300. It weighs about 195 kg and ships in a 53 × 53 × 81 cm case. Use the tables below to identi...

Quick Answer Two questions, two short answers.1. What is HPV95? HPV95 is the pump model designation for the Komatsu PC200-7 / PC220LC-7 main pump. It describes the type and size class of the pump — a variable-displacement piston pump. It is a model name, not an order number.2. What is the difference between 708-2L-31123 and 708-2L-00300? They are two order numbers for two different builds in...

Quick Answer 708-2L-00500, 708-2L-00400 and 708-2L-00490 are three order numbers quoted for the Komatsu PC200-8 main pump. They belong to the same 708-2L pump family — only the final block differs, and that block is what encodes the build. So the three numbers are three builds of one family, not three names for one part. Which one is right for you is decided by your pump nameplate code and y...

Quick Answer The 708-2G series is the Komatsu main-pump number group used on the PC300 / PC350 / PC360 class excavators — the 30-tonne platform that carries the HPV140 pump. The series contains more than twenty numbers, and they are not all the same kind of thing: some are complete pump assemblies, some are internal components of the pump, and some belong to different machines altogether. Re...

Quick Answer Every piston pump leaks a little oil internally, and that oil has to go somewhere — it drains out of the pump case through the case drain line. That is the diagnostic gift: case drain flow is internal leakage made visible and measurable. On a PC600-6, measuring case drain flow at operating temperature, at a defined operating point, tells you how worn the pump is long before the ...
