If you've got a classic Massey Ferguson 135, 240, or other tractor running that trusty old Perkins engine, you know how important clean oil is to keep things running smooth. These engines are legendary for their reliability, but they need fresh filters to stay that way. This genuine-spec oil filter is built to handle whatever your Perkins 3.152 or 4.203 throws at it. What You're Getting Full-flow design that filters every drop of oil going through your engine 140mm length gives you more filtration surface area than shorter filters Anti-drain back valve keeps oil in the filter when you shut down, so you get instant pressure on startup Bypass valve ensures oil keeps flowing even if the filter gets clogged Heavy-duty steel canister that won't fail under pressure Built for Real Farm Work This filter fits those iconic British tractors powered by Perkins 3.152 and 4.203 engines that farmers have trusted for decades. Whether you're running hay equipment, working cattle, or handling general farm chores, these tractors are still workhorses on farms across the country. The simple, reliable design of both the engine and this filter means less downtime and more productivity. Made to Last Perkins engines are built tough, and so is this filter. The multi-layer filter media captures everything from big chunks to microscopic particles that can wear out your engine bearings. The robust construction handles the pressure spikes and temperature swings that come with hard farm work, season after season. Installation Notes Change this filter every time you change your oil—typically every 200-250 hours of operation. Put a thin film of clean oil on the gasket before installing, then hand-tighten just three-quarters of a turn past gasket contact. Don't use a filter wrench to tighten it or you'll likely damage the gasket and create a leak.
