What It Is

This is a replacement tachometer cable for Massey Ferguson and Landini tractors. It connects the engine to the tachometer gauge, transmitting mechanical rotation to display engine RPMs—critical for monitoring PTO speed, throttle settings, and engine load during mowing or field work.

Fitment & Compatibility

Before buying, confirm your tractor’s model and year. This cable fits Massey Ferguson models 165, 168, 175, 178, 180, 185, 188, 231S, 243, 261, 265, 270, 271, 275, 281, 282, 283, 285, 290, 298, 565, 575, 590, 1080, 30D, 50, 50E, 375, 390, and Landini 7830. It replaces OEM part numbers 1682557M91 and 1876289M92.

Critical checks:

• Length: Measure your existing cable end-to-end (including fittings). This cable is typically 40–50 inches, but variations exist—compare to yours.
• Fittings: Ensure both drive and gauge end fittings match (square or hexagonal drive tip, threaded or clip-on gauge connection). Most Massey uses a 0.130" square drive at the engine and a threaded barrel at the gauge.
• OEM vs aftermarket: This is a non-OEM replacement. It should work, but slight differences in cable housing diameter or ferrule length can cause binding or gauge misalignment.
• Engine type: Verify your engine has a mechanical tachometer drive port (often on the injection pump or timing gear cover). Some later models use electronic tachs—this cable won’t work.

Key Things to Know

• Quality is average. With only 3.8 stars and 3 reviews, expect standard aftermarket construction. The cable core may be slightly stiffer than OEM, making routing tight corners harder.
• Installation difficulty: Moderate. You’ll need to disconnect the cable at both ends, remove the old one (may be seized), and route the new one without kinking. Lubricate the core lightly with white lithium grease before installing to reduce friction and extend life.
• Common gotcha: The drive tip can shear if the cable is too short or routed with a sharp bend. Always leave a gentle arc—no 90-degree turns. If your gauge needle jumps or reads erratically, the cable is likely binding or the core is damaged.
• Check the gauge first. If your tachometer is stuck or dead, the problem might be the gauge itself, not the cable. Test by spinning the cable end by hand—if the gauge moves, the cable is fine.

Should You Buy It

Buy this cable if you have a compatible Massey Ferguson or Landini tractor with a mechanical tachometer, your old cable is broken or seized, and you’re comfortable with a basic DIY install. Skip it if you need an exact OEM match, have an electronic tach, or want a premium cable for heavy-duty use—consider a genuine Massey Ferguson part instead. At $25.64, it’s a budget-friendly fix for a common wear item.
