When you're running a mixed fleet of compact and utility tractors, keeping track of different oil filters for each machine can get complicated fast. This universal 138mm (5.5 inch) oil filter solves that problem by fitting a wide range of 4-cylinder tractor engines across multiple brands. One filter that works on several different machines means less time searching through parts books and more time getting work done. What You're Getting 138mm length provides extra filtration capacity compared to shorter filters Premium filtration media traps dirt, metal particles, and combustion byproducts before they can damage your engine Anti-drainback valve keeps oil in the filter when you shut down, protecting against dry starts Bypass valve ensures oil keeps flowing even if the filter gets restricted Universal compatibility simplifies inventory and reduces parts complexity Built for Real Farm Work This filter handles the 4-cylinder engines found in compact and utility tractors—the workhorses that handle hay production, livestock chores, food plot maintenance, and all the daily tasks around smaller operations. These engines are built for reliability and fuel efficiency, making them popular choices for operations that need dependable power without the complexity of larger machines. Made to Last Your 4-cylinder engine works hard in dusty conditions, handles varying loads, and puts in long hours during busy seasons. This filter's quality construction stands up to high oil pressure and temperature swings while the longer 5.5-inch design provides more surface area for capturing contaminants. Better filtration means cleaner oil circulating through your engine, which translates to longer engine life and fewer costly repairs. Good to Know Change this filter with every oil change—typically every 100-200 hours depending on your operating conditions. Always coat the rubber gasket with a thin layer of clean oil before installation, then hand-tighten only three-quarters of a turn after the gasket contacts the mounting surface. Keep a few of these universal filters in stock since they fit multiple machines in your fleet.
If you've ever watched the oil pressure gauge drop or heard that telltale engine knock that means trouble, you know how important clean oil is to your tractor's heart. This filter serves the legendary Ferguson TEF20 "Little Grey Fergie" and Massey Ferguson FE35 - tractors that revolutionized farming in the 1940s and 50s and became some of the most popular small tractors ever built. Whether you're powering a sawmill, baling hay, or working around the farmyard, this filter keeps your engine's oil clean and flowing like it should. What You're Getting 138mm long design that fits the unique oil system requirements of these classic 4-cylinder engines Paper filtration element that captures harmful contaminants without restricting oil flow Built-in bypass valve system ensures oil circulation even if the filter gets restricted, protecting your engine from oil starvation Direct replacement for original equipment - no modifications or adapters needed Built for Classic Farm Work These 20-horsepower workhorses handled everything from plowing small fields to powering sawmills and hay balers. The tractors this filter serves were workhorses of British agriculture, commonly used for field cultivation, hay making, livestock management, and mixed farming - today they're highly valued by collectors and small-scale farmers who appreciate their simple, reliable design. Made to Last The paper filtration medium provides excellent contaminant removal efficiency while maintaining proper oil flow rates for vintage engine designs, with quality construction that ensures reliable performance throughout the recommended 200-hour service interval. This filter is specifically engineered for the lower oil pressures and flow rates typical of 1950s-1960s tractor engines. Installation Notes Install with the engine cool and oil drained to working level - always replace the gasket and hand-tighten an additional three-quarters turn after gasket contact. Change your oil and filter every 200 operating hours to keep these vintage engines running strong. Always verify your specific tractor model and engine serial number compatibility before installation, as some early and late production models may have different specifications.
