I keep my tractor on the farm where my son lives and he called to tell me that the John Deere 5045E was acting strange. He said that after starting it doesn’t always go as fast as it should. It seems to me that the clutch may be slipping. He tells me that there is NO free play on the pedal at all. I have read that there should be 20 or 25mm. Could this be the problem or do you think the clutch needs to be changed or could it be something else? Thanks for any advice. We have somewhere close to 300 hours on the 2014 John Deere 5045e Tractor.
Your tractor appears to have premature clutch wear caused by operating technique. Some of the causes are the use of the clutch pedal, starting the tractor in too high gear. When the loader is used, it is switched to range A to move the tractor towards the product to be loaded.
The clutch actuation pedal must be adjusted so that the pressure plate can exert maximum pressure on the traction clutch disc. After free pedal travel, if the clutch continues to slip, the clutch disc will need to be replaced, which will require splitting the tractor.
Clutch pedal free travel is not created when the clutch disc wears and the pressure plate disc moves a little closer to the flywheel, which brings the drive finger closer to the brg. of expulsion. When the PP fingers apply enough pressure against the throwout brg this causes the PP not to apply the correct pressure on the traction clutch disc allowing the disc to slide more easily creating a “vicious circle”.
The clutch discs on John Deere 5045 tractors are made of a metallic / ceramic material. (When the tractor is stationary for a long time, rust accumulates between the clutch disc and flywheel and between the clutch disc and pressure plate. When the tractor is started, the rust acts as an abrasive and wears the clutch disc, as well as the faces of the flywheel and the pressure plate. As these parts wear the free play in the clutch is less and less. It is recommended that, if you are going to leave one of these tractors idle for some time time, depress the clutch pedal, this will allow air to circulate inside the clutch housing and reduce or eliminate the rust condition.
