Case Study: Landini Series 5-100 Wheel Seal Repair

A Clean, Lasting Fix That Stops an Oil Leak in Its Tracks

At Farm and Fleet Services, we know that spotting oil where it shouldn't be can be a real worry — and often a sign of something that needs attention sooner rather than later. As the trusted machinery specialists for Cornwall and West Devon, we take genuine pride in prompt response, honest diagnosis and repairs built to last. This job was a fine example of that approach in action, and here's how we got a hardworking Landini Series 5-100 running clean and dry once more.

The Problem

The customer got in touch to report something he'd noticed while working: oil coming around the wheel. It's exactly the kind of fault that's easy to spot but tempting to leave, yet a leak like this rarely fixes itself — and left alone, it can lead to bigger problems and unwelcome downtime further down the line. Understanding just how much rests on a dependable tractor, our team set to work getting straight to the root of it.

The Diagnosis

There's no substitute for a proper hands-on inspection. Rather than guessing at the cause, our engineer checked the fault carefully to pinpoint exactly what was going on. The verdict soon became clear: the wheel bearings had developed slight play, and that movement was causing oil to leak out past the seal.

A methodical, step-by-step check meant we identified the culprit quickly and knew precisely what the job called for — no unnecessary work, and no shortcuts.

The Solution

With the fault confirmed, our team carried out a thorough, lasting repair:

• Stripped out the trumpet housing to gain full, clear access to the affected components
• Replaced the worn wheel bearings to remove the play and restore a tight, smooth-running wheel
• Fitted new seals to stop the leak completely and keep everything sealed for the long haul

Rather than settling for a quick patch, we replaced everything the job needed — sparing the customer the frustration and expense of a repeat fault down the line.

The Result

The Landini Series 5-100 was returned to work running clean and dry, with the oil leak resolved completely. Just as importantly, the customer left with complete confidence that the repair had been done properly, first time — no return trips to
