Oil Filters for Cummins QSM11

Oil filters remove contaminants and particles from the engine oil, protecting engine internals from premature wear. We offer multiple spin-on oil filter types, each with high-efficiency media and rugged construction to handle demanding duty cycles.

Standard Oil Filter (Metric Thread)

• Spin-on design for fast replacement
  
  

• Thread size: M95 x 2.5
  
  

• Diameter: 4.65 inches
  
  

• Height: 11.69 inches
  
  

• Compatible with most QSM11 CPL configurations
  
  

Alternate Oil Filter (Inch Thread)

• Spin-on design
  
  

• Thread size: 2 1/4" - 12 UN
  
  

• Same dimensions as the metric version
  
  

• Offers flexibility based on engine configuration and regional sourcing
  
  

Oil Pan Gasket for Cummins QSM11

The oil pan gasket forms a critical seal between the oil pan and the crankcase, preventing leaks and maintaining oil pressure. This gasket is engineered specifically for QSM11, M11, L10, and ISM engines that utilize an external damper configuration.

Material Benefits:

• Heat-resistant rubber composite construction
  
  

• Precision die-cut to fit OEM oil pans
  
  

• Designed to withstand vibration and thermal cycling
  
  

Oil Cooler for Cummins QSM11

The oil cooler maintains stable oil temperature under load, preventing overheating and ensuring lubrication consistency. We supply the complete oil cooler unit for Cummins QSM11 applications, along with the corresponding seals and gaskets required for proper installation.

Oil Cooler Features:

• Robust brazed-aluminum or stacked-plate design
  
  

• Reduces oil temperature in marine and high-duty cycle environments
  
  

• OEM-fit drop-in solution for QSM11 cooling systems
  
  

Supporting Oil Cooler Components:

• Oil Cooler Gasket: Two required per cooler; ensures tight sealing on both sides of the cooler core.
  
  

• Oil Cooler Seal: Two required per engine; provides oil-tight integration between the cooler and block.
  
  

Hand Hole Gasket for QSM11 Engines

The hand hole gasket allows for periodic maintenance inspection of the crankcase without introducing contaminants. Our gaskets for the QSM11, L10, M11, and ISM engines are designed with excellent resilience and sealing properties, ensuring a secure closure after servicing.

Zinc Anode for Oil Cooler Corrosion Protection

Marine QSM11 engines benefit from zinc anodes designed to protect the oil and fuel cooler from galvanic corrosion. These threaded brass plugs contain a replaceable zinc core that sacrifices itself to preserve the integrity of the cooler housing.

Specifications:

• Brass NPT 3/8” plug
  
  

• Zinc length: 1 inch
  
  

• Easy installation and replacement during routine service
  
  

Oil Pressure Switches for Cummins QSM11

Monitoring oil pressure is critical for engine safety and performance. Diesel Pro Power offers a wide selection of mechanical make/break switches, each designed to activate or deactivate auxiliary systems such as alarms or shutdown controls.

Available Pressure Ratings:

• 5 PSI Switch: Activates/deactivates at 5 PSI; used for basic pressure warnings
  
  

• 10 PSI Switch: Suitable for low-pressure alerts on marine and industrial setups
  
  

• 20 PSI Switch: Provides mid-range activation for critical systems
  
  

• 27 PSI Switch: Common for high-sensitivity safety systems
  
  

Each switch is threaded for 1/8” NPT ports and is designed for use with Cummins and Detroit Diesel engines.

Oil Filter Removal Tool for QSM11 Servicing

Changing spin-on filters can be challenging in tight spaces. Our adjustable oil filter wrench accommodates filters ranging from 4-21/32” to 5-5/32” in diameter, perfect for Cummins QSM11, M11, L10, and Detroit Diesel engines.

Engine Oil System Maintenance Tips for Cummins QSM11

Maintaining your QSM11 oil system is crucial for long-term reliability. Below are some tips for maximizing uptime and avoiding preventable failures:

Inspect Regularly

Check for leaks around the oil pan, cooler, and filter areas. Monitor oil levels daily on high-hour marine engines.

Replace Filters on Schedule

Spin-on filters should be replaced based on operating hours and environmental conditions. More frequent changes are recommended for dusty, humid, or high-load environments.

Monitor Oil Pressure

Always verify oil pressure during startup and while under load. Abnormal readings may indicate clogged filters, worn bearings, or a failing oil pump.

Use the Correct Oil Grade

Ensure you're using the recommended SAE oil viscosity for the ambient temperature and application. Marine engines often require higher detergency levels.
