The Job: Gear Changing Issues Lead to a Ford 5635 Teardown
This Ford 5635 was having trouble changing gears, so a fielding mechanic got to work tracking down the cause.
After splitting the tractor and opening up the transmission, the culprit revealed itself: a broken roll pin that had been quietly causing trouble and gradually wearing out the synchro hub.
That small failure had already started creating shifting issues and, left unchecked, would’ve led to bigger and more expensive problems down the track.
The workshop replaced the damaged components and got the transmission back on track, but that wasn’t the only thing getting attention during the repair.
The Fix: A Transmission Rebuild and a Seat Worth Sitting In
Once the source of the problem was identified the damaged synchro hub and associated components were all needing to be replaced. ProPart supplied the whole shabang, big and small, to restore smooth gear changes and prevent further wear within the transmission. Those parts included the following:
But while the tractor was already in the workshop, the owner decided it was time to upgrade something they interact with every single day.
Because after spending years bouncing around paddocks and soaking up countless hours of vibration, the original seat had well and truly earned retirement.
A brand-new vinyl suspension seat found its way onto the shopping list and instantly gave the old Ford a fresh lease on life.
Sure, the transmission repair was important. But we’re willing to bet the driver noticed the seat upgrade first.
ProPart Insights: One of the Best Value Upgrades You Can Make
We spend a lot of time talking about transmissions, engines and driveline components, but one of the most overlooked upgrades on any tractor is the seat. It’s the one component the operator uses every single hour the tractor is running.
A worn-out seat can make long days feel even longer. Poor support and tired suspension all add up over time.
A quality replacement seat doesn’t just improve comfort. It can reduce operator fatigue and make those long days in the cab far more enjoyable.
If your tractor is already in the workshop for maintenance or repairs, it’s often the perfect time to consider replacing a seat that’s seen better days.
Your tractor might not thank you for it, but your backside certainly will.
