Heavy-Duty Spin-On Lube Oil Filter – Model 3754002100

A full-flow, bypass-equipped spin-on canister built for large-displacement diesel engines on mining excavators, crawler cranes, and stationary generator sets. With a 118 mm OD × 260 mm length canister and 1⅜-16 UN thread, it delivers the media area needed for high-soot, long-drain operation on engines in the 16–24 L class. A glass-fiber 10–15 µm variant is also offered for hydraulic auxiliary or compressor-lube duty on the same equipment platforms.

Key Features

• Std. lube version: Resin-impregnated cellulose, 22 µm @ 99 % efficiency (SAE J1858), 9 µm @ 50 %

  
  

• Hyd-aux variant (optional): Glass-fiber composite, 10–15 µm, β₁₀ ≥ 200, ISO 16889 multi-pass

  
  

• Rolled carbon-steel shell, zinc-plated end caps, corrosion-resistant finish

  
  

• Integrated bypass valve and anti-drain-back membrane for dry-start protection

  
  

• NBR gasket standard (110 mm OD / 98 mm ID); FKM available for high-temperature estates

  
  

• Two units per engine typical on V-configuration heavy diesels

  
  

Technical Specifications

Application Guidance

Lube duty – Primary full-flow filtration on large mining excavators (120-ton-class crawler excavator platforms), high-hour generator sets, and heavy construction power units with 16–24 L displacement diesels. The 260 mm length and 118 mm OD support 500+ hour drain intervals under continuous load. Two canisters per engine is standard on V-configuration platforms.

Hyd-aux duty (glass-fiber variant) – Compressor-lube loop, PTO-lube, or hydraulic return-guard on the same chassis where a heavy-duty 1⅜-16 UN spin-on head is already present. The 10–15 µm grade protects servo valves and variable-displacement pump bearings in auxiliary circuits.

📎 Cross-references commonly seen: P550777, LF777, ME034879, 330432 — all share the 118×260 / 1⅜-16 UN footprint. Confirm gasket (110/98 mm) and bypass setting before substituting across platforms.

Fluid Compatibility

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

  
  

• Mineral hydraulic oil (ISO HM/HV) – hyd-aux glass-fiber version only

  
  

• Diesel fuel – indirect (fuel-stage versions exist under same pattern, confirm media)

  
  

• HFC water-glycol – NBR acceptable; FKM recommended

  
  

• Not for phosphate ester (HFDR) without seal upgrade

  
  

Installation & Service

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

   
   

2. Lubricate gasket with clean oil, spin on by hand until seated, then ¾–1 full turn — do not over-torque; no strap wrench on the canister.

   
   

3. Pre-fill if head design allows; run engine to operating temperature and check for leaks at pressure.

   
   

4. Replace per OEM hour interval (typical 500 h mining / 250–500 h generator) or when ΔP / bypass indicator signals clogging.

   
   

5. Log change intervals — useful for trending soot load on long-drain schedules.

   
   

Quality Assurance

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

  
  

• ISO 16889 (hyd-aux) – multi-pass β-ratio

  
  

• ISO 2941 – collapse/burst (hyd-aux cage)

  
  

• ISO 2943 – media/fluid compatibility

  
  

• Shell burst test per batch

  
  

Ordering

Quote 3754002100 with duty (lube cellulose / hyd-aux glass-fiber), micron rating, and seal material. Variants 3754002100D / 3754002100E also available — specify suffix if your platform calls a specific sub-grade. Cross to common P550777 / LF777 / ME034879 patterns available on request — provide engine model and existing OEM number for confirmation.

All values nominal; confirm thread (1⅜-16 UN), gasket (110/98 mm), and head pressure class against your actual filter head before installation.
