Clutch adjustment 445 long

rrman61 · Nov 5, 2017

Changed the clutch on this tractor a couple years ago.it recently smells like burnt clutch material when I change gears/release clutch.does anyone know if I need to adjust the linkage or adjust the clutch itself? This is a fiat built tractor

How's the freeplay adjustment?

As a clutch wears, the linkage needs to be adjusted. You should have an inch or so pedal free travel at the top before the release bearing contacts the pressure plate fingers.

I have seen a couple of those engines go bad with crank issues as the thrust washer wore out, Whole crank will move forward when you push in the clutch.

I'll check the free play this afternoon when I get off.it was adjusted according to specs at the clutch/pto clutch when installed 150 or so hours ago

Its the PTO clutch that does the damage as its plate is against the flywheel,not the engine clutch.Since the 445 has a two stage clutch controlled by the foot clutch lever only
it won't happen unless someone were to keep holding the foot clutch all the way down for on extended period.On the 460 Long ,Oliver 1365 etc the PTO clutch is controlled by an
independent lever which allows for PTO clutch to held in the disengaged position for extended periods.

If you have some free travel than it sounds like the fiber clutch facing is failing,pretty common thing to happen.Much better to install a button type engine clutch in those tractors
it'll be a little jumpy but will last a long time.Also pays to buy the complete clutch assembly already set up unless you fully understand how to set them up and have the gauges to do.
it.

Most all the clutch systems I have encountered do not have any "adjustment" beyond free pedal travel. The clamping force of the pressure plate is predetermined by the springs that were installed by the factory.

If it is slipping and burning, the only thing beyond an abnormal failure of the linings of the clutch disk would be an improper adjustment of the pedal free travel, as in there would be no travel at all, even "negative" free pedal travel. In other words even with your foot off the clutch pedal, the mechanism is holding the clutch slightly disengaged.

Occasionally pressure plates will come with lockout bolts installed that hold the pressure plate compressed for ease of installation. The tractor should never have moved if you forgot to remove those, though.

Those Fiat clutches are different from any I have ever seen the engine/transmission clutch disk is encased in the pressure plate/clutch pack assembly and are adjustable once you can get to them.If they aren't adjusted correctly from the get go they'll give problems.
