Description
When your air cleaner system isn’t breathing right or you notice dust getting past your filter, there’s a good chance your relief valve housing has worn out or cracked. This housing is what keeps your air cleaner working at the right pressure, making sure clean air flows properly to your engine while preventing system damage from pressure buildup.
What You’re Getting
- 75mm inner diameter fits perfectly with standard air cleaner assemblies
- Precise pressure regulation keeps your air filtration system working like it should
- Durable construction stands up to engine vibration and temperature swings
- Direct replacement part that installs without modifications
- Proper venting prevents system damage from over-pressure conditions
Built for Real Farm Work
This relief valve housing is designed specifically for Massey Ferguson 100 Series tractors, particularly the popular 135 and 148 models that have been workhorses on farms for decades. Whether you’re running a 135 through dusty harvest operations or using a 148 for loader work and general farm chores, this housing ensures your air cleaner system maintains proper pressure balance for optimal engine protection.
Made to Last
Farm tractors face tough conditions, and air cleaner components take a beating from constant vibration, temperature changes, and pressure cycling. This housing is built with materials that handle the demands of agricultural use, maintaining proper sealing and pressure relief function season after season.
Installation Notes
This housing connects directly to your existing air cleaner assembly with the 75mm opening. Make sure the sealing surfaces are clean before installation, and check that the relief mechanism moves freely. A stuck relief valve can cause poor engine performance or even filter damage during dusty conditions.
