Komatsu 714-07-28703 Filter unit

Product Introduction

1. Design feature of filter element 714-07-28703

Filter element 714-07-28703 features a multilayer design optimized for maximum filtration efficiency and durability. Key components include filter media, housings (outer and inner), sealing elements, and fasteners—each made from high-quality materials that meet Komatsu manufacturer standards.

Filter material: A high-density (2.5 g/cm³) synthetic polyester fiber with a porosity of 10 µm is used. This material has two key advantages: firstly, it retains up to 99.5% of small particles (including metal particles 5–10 µm in size, which are the main cause of wear in hydraulic pumps), and secondly, it has high liquid permeability (flow rate up to 15 l/min), which does not create excess pressure in the system. The surface of the material is treated with a hydrophobic compound, which prevents moisture accumulation (which causes corrosion of metal components) and increases the filter service life by 25–30% compared to cellulose-based alternatives.

Housings: The outer housing is made of impact-resistant polyamide 66 (PA66) plastic with 30% fiberglass. The material is resistant to temperature fluctuations (-40°C to +120°C) and chemicals (gasoline, diesel fuel, Komatsu HD 46 hydraulic oils). The internal support frame is made of galvanized 08KP sheet steel. It prevents deformation of the filter material under high system pressure (up to 30 MPa). The housing dimensions exactly match the original filter: height 180 mm, diameter 95 mm, internal mounting diameter 30 mm. This allows the element to easily install into standard Komatsu filters without any additional adaptations.

Sealing elements: The kit includes two seals made of elastic nitrile rubber (NBR)—an upper (95 mm diameter) and a lower (30 mm diameter). The seals have a "D" shape with a ribbed surface, ensuring a tight seal with the filter housing and preventing unfiltered liquid from "slipping" into the system. NBR is wear- and age-resistant—the seals have a service life of up to 2 years with proper use.

Fasteners: Stainless steel 12X18H10T fasteners are provided to secure the filter material to the internal frame. The fasteners are M4×8 threaded bolts with washers. They provide a secure fit and are easily disassembled when replacing the material (although filter 714-07-28703 is designed for single use, this is convenient for component disposal).

2. Technical characteristics and compliance with standards

Filter element 714-07-28703 fully complies with Komatsu technical requirements and undergoes strict quality control at all stages of production, from material manufacture to final packaging. Key specifications include:

Warranty period: 1 year from date of purchase (subject to use in accordance with Komatsu recommendations).

In addition, the product is certified in accordance with international standards:

ISO 16889:2018 (standard for hydraulic filters - confirms filtration efficiency and safety of use).

ISO 9001:2015 (quality management system – guarantees consistent quality at all stages of production).

SAE J1839 (heavy equipment component standard - certifies compatibility with Komatsu electronics and mechanics).

3. Advantages compared to analogues

The 714-07-28703 filter element has a number of key advantages that make it the preferred choice for Komatsu equipment owners, compared to non-original filters or similar products from other brands:

High filtration efficiency and system protection: Thanks to a synthetic material with a density of 10 microns, the element retains almost all small contaminants, including metal debris, sand particles, and corrosion products. This prevents wear on hydraulic pumps, motors, and valves—according to service prices.
