REDX filters meet or exceed OEM specifications. Thanks to advanced filtration media, they effectively remove soot, metal filings, and other contaminants from the oil, protecting bearings, turbocharger, and other key engine components from premature wear.

Features of REDX 320/B4420 Filter

High Capacity: Multi-layer filter media structure ensures high contaminant holding capacity, allowing safe operation throughout the oil change interval.
Robust Housing: Reinforced filter can withstands oil pressure spikes, preventing deformation and leaks.
By-pass Valve: Integrated safety valve guarantees engine lubrication even in case of complete filter clogging or during cold starts.
Anti-Drain Valve: Prevents oil from draining out of the filter after engine shutdown (Anti-Drain Back Valve), ensuring immediate oil pressure upon restart.

Application in JCB machinery

Machine Group Example Models
Backhoe Loaders 3CX, 4CX, 5CX (Eco, Super, Sitemaster series - DieselMax engines), 1CX, 2CX, MIDI CX
Telehandlers Loadall: 531-70, 535-95, 535-125, 535-140, 540-140, 540-170, 541-70, 550-140 (and many others)
Crawler Excavators JS130, JS145, JS160, JS180, JS190, JS200, JS210, JS220 (Models with JCB engines)
Other Machines Site Dumpers, Wheel Loaders (403, 406), RTFL Forklifts, Vibromax Rollers, Skid Steers (Robot)

The filter fits JCB engines produced from 2005 onwards. For older machines (Perkins engines), a different filter is required.

Related Parts and Hardware

The filter comes with an integrated gasket. When changing engine oil, we also recommend replacing fuel filters and the air filter to ensure comprehensive powertrain maintenance.

⚠️ Safety Warning

Neglecting oil filter replacement leads to contaminant buildup, which can clog oil passages, causing oil pressure drop and engine seizure. Regular service is the foundation of long machine life.

Part Role in the Machine and Failure Diagnostics

Filter 320/B4420 is responsible for cleaning the engine lubricating oil from soot, dust, filings, and combustion products.

  • › Low oil pressure (clogged filter).
  • › Black, thick oil (filter used too long).
  • › Leaks from under the filter gasket (improper installation or damaged gasket).
  • › Metallic knocks in the engine (effect of lack of lubrication).

🔧 Expert Guide: Key Installation Tips

  1. Gasket Lubrication: Before screwing on the filter, coat the rubber gasket with a thin layer of clean engine oil. This will prevent damage and make removal easier in the future.
  2. Tightening: Screw the filter on by hand until it stops, then tighten 3/4 of a turn. Avoid using a wrench to tighten, so as not to crush the can.
  3. Level Check: After starting the engine, check the filter for leaks, then shut down the engine and top up the oil level that filled the new filter.

Frequently Asked Questions (FAQ)

Does the filter fit Perkins engines?

No. Perkins engines (used in JCB before 2005) have a different thread and filter dimensions. This model is dedicated exclusively to JCB DieselMax/EcoMax engines.

What thread type is it?

The mounting thread is metric M22x1.5. This is standard for newer JCB engines.

How often should the oil be changed?

The standard interval for JCB DieselMax engines is 500 hours (using high-quality oil). Always follow the machine's service manual recommendations.
