Crankcase Breather Filter suitable for CAT C4.4 C6.6 - 2735711

Technical Specification and Compatibility

Crankcase breather filter with part number 2735711 from the REDX offer. It is a specialized canister filter used in Caterpillar (CAT) machines equipped with C4.4, C6.6, and C7.1 series engines. Its task is to separate oil mist from blow-by gases, which protects the intake system from contamination and ensures compliance with environmental standards.

Part Number: 2735711
Component Type: Crankcase Breather Filter
Height: 177 mm
Outer Diameter: 93 mm
Inner Diameter (Seal): 71 mm
Thread: M22 x 1.5
Type: Spin-on
Manufacturer: REDX

REDX breather filters effectively capture oil particles from gases escaping from the crankcase. This prevents oiling of the turbocharger and intercooler, which is crucial for maintaining the efficiency of EGR-equipped engines.

Features of REDX 2735711 Filter

Environment & Engine Protection: Reduces harmful emissions and prevents carbon buildup in the intake system.
Spin-on Design: Convenient metal canister form with M22x1.5 thread allows for quick replacement without dirty hands and oil contact.
High Efficiency: High surface area filter media ensures free gas flow while effectively separating oil.
Versatility: Fits a wide range of CAT machines, from wheeled excavators and loaders to dozers and rollers.

Related Parts and Hardware

The breather filter is part of the lubrication/ventilation system. When replacing it, it is worth checking the condition of engine oil filters and air filters to ensure comprehensive engine protection.

⚠️ Operational Warning

A clogged breather filter causes pressure buildup in the engine crankcase. This can lead to oil leaks through seals (e.g., crankshaft seals) and increased oil consumption. Regular replacement of this filter is often overlooked but is crucial for engine tightness.

Part Role in the Machine and Failure Diagnostics

Filter 2735711 vents the crankcase and separates oil.

  • › Oil leaks (pressure increase due to clogged breather).
  • › Oil in intake/turbo (faulty separation).
  • › Excessive smoking (oil combustion).
  • › Engine covered in oil.

🔧 Expert Guide: Key Installation Tips

  1. Interval: Replace the breather filter according to the machine's maintenance manual (usually every 500 or 1000 hours), do not wait for failure symptoms.
  2. Gasket: Before screwing on, lubricate the filter gasket with clean oil. This will prevent it from twisting and facilitate later removal.
  3. Tightening: Tighten by hand until snug, then slightly with a wrench (with care) to ensure tightness but not crush the gasket.

Technical FAQ and Trivia

What is "blow-by"?

"Blow-by" are combustion gases that escape from the combustion chamber past the piston rings into the crankcase. They must be vented (via the breather), and the breather filter cleans them of oil mist before re-introduction into the intake or atmosphere.

Why is the filter so large?

The 177 mm height results from the need to provide a large surface area of coalescing material. A filter that is too small would quickly become saturated with oil, blocking gas flow and causing pressure buildup.

Ecology trivia

In older engines, the breather was simply a tube vented under the engine ("open breather"), dripping oil onto the ground. Modern systems with filters like 2735711 (closed CCV) are a requirement of emission standards to prevent oil from entering the environment.
