Heavy-Duty Spin-On Filter Pair – Models ME015254 & ME056670

Two spin-on cartridges from the Mitsubishi heavy-duty engine ecosystem, covering lube-oil and fuel/water-separation duties on the same power-pack platform. ME015254 is a full-flow lube-oil filter for 6D24/6D40-class engines used on Fuso Super Great trucks, crane carriers, and excavator power units, while ME056670 is a fuel-spin-on with integrated water-separator media, serving 6D22CT, 8DC9, and related diesel families on cranes, wheel loaders, and bus chassis. Both can be carried over into the hydraulic auxiliary loops of the same machines — ME056670 in particular, where water ingestion is a concern (marine hydraulics, forestry, wash-down environments).

Key Features

• ME015254: Full-flow lube, cellulose media, anti-drain-back valve, 1½-12 UN or M24-class thread depending on head, robust rolled-shell construction for 500+ hour drain intervals

  
  

• ME056670: Fuel / water-separator spin-on, M24×1.5 thread, 93–94 mm OD × 172 mm length, 30 µm @ 99 % (SAE J1985), 95 % emulsified-water separation efficiency

  
  

• NBR gasket standard; FKM available for high-temperature estates

  
  

• Bypass valve integrated per head design; square-section gasket 90 mm OD / 79 mm ID (ME056670)

  
  

Technical Specifications

Application Guidance

ME015254 – Primary full-flow lube on 6D24, 6D40, and related heavy-duty diesels used in Fuso Super Great trucks, Kato HD-series cranes (8DC9/8DC90CT power), and excavator carrier engines. The tall canister (~260 mm) supports high-soot, long-drain operation. On hydraulic power packs driven by the same engines (crane superstructure, carrier hydraulics), ME015254 also guards the compressor-lube or PTO-lube auxiliary loop.

ME056670 – Fuel-stage filter/water-separator on 6D22CT (Furukawa FL-330 loader, Kato HD1250SEV crane), 6D40 Fuso trucks, 8DC9 Kato HD1880/HD2500SEV cranes, and King Long buses. The 30 µm / 99 % rating plus 95 % water-stripping makes it useful beyond fuel: on marine or forestry hydraulic skids where the tank breather can pull in moisture, a ME056670 in glass-fiber variant (if specified) can serve as a hydraulic return-guard with water-separation benefit — though the standard cellulose version should stay on fuel duty.

Fluid Compatibility

• Mineral engine oil (API CK-4, CJ-4) – ME015254

  
  

• Diesel / middle-distillate – ME056670

  
  

• Mineral hydraulic oil (HM/HV) – ME015254 auxiliary loops; ME056670 only if glass-fiber variant specified

  
  

• HFC water-glycol – NBR acceptable; FKM recommended

  
  

• Not for phosphate ester (HFDR) without seal upgrade

  
  

Installation & Service

1. Clean filter head face; inspect center tube and thread.

   
   

2. Lubricate gasket with clean fluid, spin on by hand until seated + ¾ turn. No strap wrench on the canister.

   
   

3. ME015254: pre-fill if head design allows; run engine to operating temp and check for leaks.

   
   

4. ME056670: prime fuel system per engine procedure; drain water-collector bowl on the head (if fitted) at each service.

   
   

5. Replace per OEM hour/km interval or when ΔP / water indicator signals.

   
   

Quality Assurance

• SAE J1858 / ISO 4548 (lube) – efficiency & capacity

  
  

• SAE J1985 / ISO 4020 (fuel/water-sep) – filtration & water-stripping

  
  

• Shell burst test, media integrity check per batch
