Tracking Down Filters and Parts for the Halla HE360LCH Excavator

[MikePhua]

The Halla HE360LCH and Its Place in Korean Excavator History
The Halla HE360LCH excavator was produced in the late 1990s during a transitional period in South Korea’s heavy equipment industry. Halla Heavy Industries, originally a diversified conglomerate, entered the construction machinery market with a lineup of excavators and loaders aimed at competing with domestic rivals like Daewoo and Hyundai. The HE360LCH was one of their larger models, weighing in at roughly 36 metric tons and powered by a Cummins LT diesel engine. It was designed for quarry work, mass excavation, and infrastructure development.
Though Halla’s equipment division eventually dissolved, many of its machines remained in service, especially in Southeast Asia, the Middle East, and parts of North America. The HE360LCH, in particular, shares design DNA with early Daewoo Solar series excavators and incorporates hydraulic components sourced from Japanese manufacturers like Kawasaki and Hitachi.
Engine Filters Can Be Sourced Through Cummins Channels
The HE360LCH’s Cummins LT engine simplifies the search for engine-related parts. Oil filters, fuel filters, and air filters can be cross-referenced through Cummins dealer networks or aftermarket catalogs. Most Cummins LT engines use standard spin-on filters, and part numbers are often stamped directly on the filter housing.
Recommended approach:

• Identify engine model and serial number from the data plate
  
• Use Cummins QuickServe or Fleetguard catalog to match oil and fuel filters
  
• For air filters, measure outer and inner diameter and length to match with Donaldson or Baldwin equivalents
  

Terminology:

• Spin-On Filter: A threaded, self-contained filter that screws directly onto the engine housing.
  
• Fleetguard: A Cummins-owned brand specializing in filtration products for diesel engines.
  

A contractor in Maine was able to source oil filters easily but struggled with fuel and hydraulic filter identification due to faded markings. Once the engine serial number was confirmed, a local Cummins distributor provided exact matches.
Hydraulic Filters May Match Doosan or Hyundai Specifications
While engine parts are relatively straightforward, hydraulic filters on the HE360LCH require more detective work. Halla sourced many of its hydraulic components from Kawasaki and Hitachi, and the filter housings often resemble those found on Daewoo Solar and early Hyundai Robex models. In some cases, the hydraulic filters are interchangeable with Doosan DX-series excavators.
Hydraulic filter sourcing tips:

• Remove filter and measure thread pitch, diameter, and canister height
  
• Compare with Doosan and Hyundai filter specs in aftermarket catalogs
  
• Check for internal bypass valve rating (typically 10–15 psi)
  
• Use cross-reference tools from brands like Wix, Parker, or HIFI
  

Terminology:

• Bypass Valve: A pressure-sensitive valve inside a filter that allows fluid to bypass the media if clogged.
  
• Canister Height: The vertical length of the filter body, critical for clearance and fit.
  

A technician in Lincoln, UK noted that many Halla hydraulic filters matched Doosan part numbers, suggesting shared supplier relationships during the 1990s.
Air Filters Require Dual Sourcing for Inner and Outer Elements
The HE360LCH uses a dual-stage air filtration system, with an outer primary filter and an inner safety element. These are often cylindrical and mounted in a horizontal housing near the engine bay. If part numbers are missing, dimensions and airflow ratings can be used to match replacements.
Air filter sourcing strategy:

• Measure outer diameter, inner diameter, and length of both elements
  
• Identify airflow rating (CFM) if available
  
• Match with Donaldson, Mann+Hummel, or Baldwin equivalents
  
• Check for compatibility with Cummins LT engine air intake specs
  

Terminology:

• Safety Element: A secondary air filter that protects the engine if the primary filter fails.
  
• CFM (Cubic Feet per Minute): A measure of airflow capacity through the filter.
  

A retired land-clearing contractor recalled that early Halla machines used Hitachi-style air housings, and switching to Donaldson filters improved dust resistance in dry climates.
Cross-Referencing Filters Without OEM Support
Since Halla no longer supports its excavator line, owners must rely on aftermarket catalogs and community knowledge. Filter manufacturers often list Halla in their legacy equipment sections, but not all models are covered. In such cases, physical measurements and thread specifications become essential.
Steps for cross-referencing:

• Remove and clean existing filter
  
• Record all visible markings and dimensions
  
• Use online filter cross-reference tools (e.g., Baldwin, Wix, Donaldson)
  
• Consult forums and equipment salvage yards for matched parts
  

Terminology:

• Thread Pitch: The spacing between threads on a filter’s mounting surface, measured in millimeters or threads per inch.
  
• Legacy Equipment: Machinery no longer supported by the original manufacturer but still in active use.
  

In Canada, a senior mechanic recommended checking filter catalogs directly rather than relying on dealer networks, which may not list Halla at all.
Conclusion
Maintaining a Halla HE360LCH excavator requires resourcefulness and a willingness to cross-reference parts across brands. With its Cummins engine and Japanese-sourced hydraulics, many filters can be matched to Doosan, Hyundai, or Hitachi equivalents. By measuring components, consulting aftermarket catalogs, and tapping into community expertise, operators can keep these legacy machines running strong. In the world of unsupported equipment, precision and persistence are the keys to reliability.
