How To Change Shift Forks In A Ford 5000 Tractor
I of the complaints we hear nigh now and then is a four speed manual that "locked upwards" when information technology was shifted from one gear to another.
The transmission is actually engaged in 2 gears at once. It can exist several combinations, but 2nd and reverse seem popular.
First, is the "why" it happened and the answer is unproblematic. Wearable on the shift gates and/or the shifter lever and guide pin combined with sloppy shifting practices.
This photo shows the bottom gates on a shifter cover. These are in fantabulous condition and show no article of clothing. A tractor with shift gates in this condition volition NOT get stuck in 2 gears at one time.
This film shows the finish of the shift lever is also in dandy shape with no apparent wear. Most volition not be this good and some will be severely worn. That'due south where the problem starts.
The shift pattern on the tractor is an "H" pattern. E'er shift gears using the straight direction of the "H". Push button or pull the lever straight to neutral and experience it snap in before moving on to the next gear choice.
This practice will assure you will never exist stuck in two gears at once. Pushing the shifter toward 1 side or the other and pushing information technology frontward or dorsum at the same time to let the gates do the guiding volition get you in trouble when the gates are worn. You're non driving a sports automobile.
If you do find yourself in this unfortunate position, it does not necessarily mean disaster. You lot shift gears, allow out on the clutch, and realize it'due south locked and won't movement.
Stop correct there! Do Not rev it up and "pop" the clutch, practise Non jerk it, stone it, bang it, or slam it. Practice NOT claw a chain on it and drag it anywhere. Brute force is Non the respond.
Any actions of this type will guarantee broken gears and serious transmission damage. Simply turn off the tractor, and remove the shifter embrace.
Hither'due south what you run across with the superlative off when everything is in neutral every bit it should be. Notice how the slots for the shift lever are all in line with each other. That's where you need it to be to get the manual back to neutral.
1st and 3rd gears work directly off the pinnacle rail. 2nd, 4th, and opposite are actuated past the plates which in plough move the lower rails and forks.
The 4 speed gears are stock-still in position and are engaged by a sliding neckband that goes onto the dentals on each gear whe it'due south selected.
This moving picture shows the lower plate shifted to the 2d gear position. You can see it's way out of line now with the other ii slots.
Here'south a motion-picture show of the 1st and 3rd gear shifter fork and sliding collar. It'due south not engaged with the dentals on either side of information technology so it'south in neutral.
Here'due south a moving-picture show of a transmission with the upper principal shaft removed and so it's easier to see the lower shaft with 2nd, 4th, and opposite. All are in the neutral position.
This is how you need it to expect to become the transmission back in neutral again. The problem is that when 2 gears are engaged at in one case and y'all permit out on the clutch, the transmission input shaft starts to turn and the 2 gears with different ratios bind up tightly against each other, locking the transmission.
You tin endeavor to pry the sliding collars off the dentals and back to the neutral position, but they can be extremely tight. Most times y'all cannot pry difficult plenty to get them released. You have to relieve some of the tension on them earlier y'all can motion them.
Again, creature strength is Non the answer. Jacking up the rear end of the tractor rarely helps because the binding came from the front of the transmission.
The reply is fairly unproblematic. Disconnect the battery for your rubber. Now rotate the engine backwards (counterclockwise looking at it from the front). This volition plow the transmission input shaft backwards and release all the pressure that was on the 2 gears so you tin easily slide the shift collars back to the neutral position.
If the fan chugalug is good and has a good grip on the pulleys yous tin can plough the engine backwards using the fan. If you can't get it to motion enough (one revolution is normally more than than enough) you may demand to find some other way such equally removing the starter and turning the flywheel with a screwdriver in the band gear teeth.
Go along checking the shift collars in the transmission. When the engine has moved backwards far plenty the collars will be free and yous tin can position everything back into the neutral position. Then you just demand to install the shift embrace and get back to piece of work.
If you stopped in time and did not get rough with it, there should be no damage. If you originally heard a loud bang when you lot allow out the clutch or yous got crude with it while trying to get information technology free, yous'll be buying some new gears for the transmission.
Replace the shifter cover with one that isn't worn or just be sure to shift information technology carefully and you lot won't accept a trouble again.
