Description

That mysterious knock that gets worse when you push in the clutch probably isn’t as mysterious as you think. When your Massey Ferguson 130 or 135 starts making that telltale noise, there’s a good chance this small but critical spring has given up the ghost. This timing cover camshaft thrust spring does the vital job of controlling end float in your camshaft – keeping it positioned exactly where it needs to be instead of wandering around inside your engine.

Key Features

Controls camshaft end float to prevent expensive timing gear wear and damage
Stops that annoying knock that changes when you work the clutch pedal
Direct replacement for weak or broken original springs – no modifications needed
Precision-engineered spring pressure maintains proper cam positioning
Prevents valve timing issues that rob power and efficiency

Built for Real Farm Work

Your Massey Ferguson 130 or 135 is likely one of your most dependable machines – perfect for everything from running the bush hog to loader work around the barn. These compact utility tractors see steady use, and inside that hardworking engine, this spring takes on the critical job of controlling camshaft movement. When it weakens or breaks, that cam starts slamming against the timing cover or engine block, wearing thrust surfaces and timing gears that are expensive to replace.

Made to Last

This might look like a simple spring, but it’s precisely engineered to apply just the right pressure. Without proper end float control, your timing gears develop excessive backlash and your valve timing goes off, which shows up as lost power and poor fuel economy. This inexpensive spring prevents thousands of dollars in engine damage by doing its job quietly in the background.

Good to Know

Installation requires timing cover removal, so it’s a good time to check your timing gears for wear while you’re in there. If you’ve been running with that knock for a while, inspect the camshaft thrust face and timing gears carefully. Clean all surfaces thoroughly during assembly and make sure the spring seats properly. Most folks budget 2-3 hours for the complete job, including cover removal and reinstallation.
