Description
You know that sinking feeling when you pop the hood and see oil droplets around a cracked filler neck, or worse yet, when you can’t even get the cap to seat properly during an oil change. A damaged oil filler neck isn’t just annoying – it’s an open invitation for dirt, moisture, and debris to find their way into your engine oil. This replacement filler neck gets you back to proper engine maintenance without the worry.
What You’re Getting
- Proper length and angle for easy access during oil changes and top-offs
- Durable construction that resists cracking from engine heat cycles and vibration
- Correct diameter ensures your oil cap fits snugly and seals completely
- Smooth interior walls prevent oil flow restrictions when adding fresh oil
- Direct bolt-on replacement that matches original mounting points
Built for Real Farm Work
Your Massey Ferguson 135, 148, 240, or 550 spends its days in dusty fields, around muddy conditions, and near corrosive chemicals – all trying to contaminate your engine oil. This filler neck maintains that critical barrier between clean oil and the outside world, whether you’re topping off before harvest or doing a full oil change after heavy PTO work.
Made to Last
Engine compartments are tough environments, and years of heat cycles eventually make original filler necks brittle where they mount to the block. This replacement uses improved materials that handle temperature swings without cracking. The proper angle and length make oil additions clean and easy, even in tight spaces around front-mounted equipment.
Installation Notes
Remove the old neck carefully – corroded ones often break during removal. Clean the mounting area thoroughly and check for cracks around the bolt holes. Use appropriate thread sealant to prevent oil seepage at the mounting point. Make sure your existing oil cap threads properly on the new neck before final installation.
