Question about The Times Case Corporation Tractors International Harvestor

1 Answer

We have an IH 986 with clutch problems. We have installed 6 clutches, 2 flywheels, new linkage, new cab mounts; everything has been replaced. After 8 hours of use, it is impossible to shift from neutral into any gear without shutting the tractor off. If this definitely a clutch problem or could it be a TA problem.

I have not worked on an IH 986 specifically, but there are lots of other things it can be other than the clutch.

First of all, since it was apart 6 times, you should tell us if there was ever any visible evidence of anything wrong?
Is the disk wearing prematurely or anything?

But assuming it was never the clutch or flywheel any of these times, there are other things it could be.
For example, if the end of the transmission shaft is supported by a pilot bushing or bearing in the back of the crankshaft, that can be enough binding to prevent shifting. Always replace the pilot bushing/bearing, (if there is one).
Another could be a bad bearing, low oil, or grabbing synchro in the transmission. Unselected gears are supposed to freewheel on their bearing on the shaft. If the bearing is binding, it is like selecting 2 gears at once. If gear oil is low, this is a common problem, because synchros will bind, tear up, and throw bits of brass into all the bearings. This will not destroy the bearings because the brass is soft, but it will cause gears that need to spin freely on the shaft, to bind up.

This is probably not a clutch problem, but a problem with a bearing or bushing between something that is spinning and something that rides on it but is not supposed to spin at the same speed.

But please check the grear oil level first.

Clutch not disengaging


Slippage
  • Slippage is a clutch problem that occurs when the pressure plate is unable to hold the friction disc against the flywheel tightly when the clutch is engaged. This causes the disc to rotate at a different speed than the flywheel. The high temperature caused by friction against the disc will eventually damage the clutch plate and necessitate a replacement. On clutches with mechanical linkage, adjustment can forestall replacement for a time.
    If you notice the engine revving abnormally as the clutch is released, and the car accelerates gradually, then it could be a slippage problem. It's possible that grease or oil on the disc is causing the slippage or the engine mount could be broken, causing the linkage to be bound up by an improperly moving engine.
    Another common cause of slippage is when the friction plate is simply worn out from use. A clutch will not last forever, and over time the clutch will begin slipping. Adjustments will not fix this problem, as a worn out friction plate will require complete replacement.
Vibration
  • A grabbing or chattering clutch is an indicator that there is a problem inside the clutch mechanism. It is an easily noticed problem. Symptoms include a vibration or jerking as the clutch is released, especially when accelerating from a stop. This problem may be the result of a damaged or broken disc, flywheel or pressure plate. It may also be caused by loose springs or worn engine mounts, according to the Integrated Publishing website on Clutch Troubleshooting.

Do not apply more grease than necessary. Too much grease could cause clutch slip or judder.
6. Using the special tool, install the clutch disc to the flywheel. When installing the clutch disc, be sure that the surface having the manufactures stamp is towards the pressure plate side.
7. Install the the clutch cover assembly onto the flywheel and install the six (6) bolts through the clutch cover into the flywheel.
8. Tighten the bolts by one or two turns at a time, in succession, to avoid bending the cover flange.
If a special tool is not available, tighten the bolt temporarily and then torque to specification in diagonal torquing sequence indicated below.
TIGHTENING TORQUE
Single mass flywheel:
15~22 N·m (150~220 kg·cm, 11~16 lb·ft)
Dual mass flywheel:
20~27 N·m (200~270 kg·cm, 14~19 lb·ft)
9. Remove the special tool.
10. Install the transaxle. (Refer to GROUP - Manual Transaxle Assembly)
11. Adjust the clutch pedal free-play. (See CH-6)
INSPECTION
1. Check the diaphragm spring end for wear and uneven height.
Replace if wear is evident or height difference exceeds the limit.
2. Check the pressure plate surface for wear, cracks and color change.
3. Check the rivets for looseness and replace the clutch cover assembly if necessary.
CLUTCH DISC
1. Check the clutch facing for loose rivets, uneven contact, deterioration due to seizure, adhesion of oil, or grease, and replace the clutch disc if defective.
2. Measure the rivet sink and replace the clutch disc if it is out of specification
3. Check for torsion spring play and damage and if defective, replace the clutch disc.
4. Clean the splines on the input shaft and install the clutch disc.
If the disc does not slide smoothly or if play is excessive, replace the clutch disc and/or the input shaft.
CLUTCH RELEASE BEARING
The release bearing is packed with grease. Do not use cleaning solvent or oil.
1. Check the bearing for seizure, damage or abnormal noise. Also check the diaphragm spring contacting points for wear.
2. Replace the bearing if the release fork contacting points are worn abnormally.
INSTALLATION
Installation is the reverse of the removal.
Then remove pressure plate and Clutch plate.

1. Insert the special tool (that came with your clutch kit) in the clutch disc to prevent the disc from falling.
2. Loosen the bolts that attach the clutch cover to the flywheel in a star pattern.
3. Loosen the bolts in succession, one or two turns at a time, to avoid bending the cover flange.

How do you change a clutch on a s10 chevy blazer?


1. remove the driveshaft.
2. remove the transmission.
3. remove the bellhousing
4. unbolt the pressure plate from the flywheel.
5. remove the clutch.
6. inspect the flywheel and pressure plate for scoring, checking, or other damage. repair/replace as needed.
7. place a clutch alignment tool into the clutch disk, insert it into the pilot bearing on the flywheel, and bolt the pressure plate back into place. Install a new throwout bearing on the clutch fork. remove the alignment tool.
8. install the bellhousing, connecting the clutch linkage.
9. replace the transmission and driveshaft.

I would *strongly* recommend buying a shop (service) manual which describes this process in greater detail. It is not rocket science, but it *is* a lot of work with many detailed steps that I glossed over above. If you are not certain that you are capable of this work, you need to take it to someone who is.

The transmission is heavy, you will need buy/rent/borrow a transmission jack to be able to safely get it in and out. Plus you need the proper ramps, wheel chocks, etc. to safely raise the truck enough to do all this, and you need a smooth, level surface to work on. A concrete garage floor is ideal, a driveway may be adequate if it does not slope much. Don't even attempt it on dirt or gravel.

The clutch disk and pressure plate should be balanced and can be mounted in any position that the mounting holes line up. If there is a hole for an alignment dowl, then it is recommended to do so. otherwise it doesnt matter.

The internal balancing is taken care of by the flywheel only.

How do you replace clutch in 1997 toyota corolla? Do you need to replace entire clutch assy or just the clutch disc?


I see. sounds like you need a new clutch. OK, here is a step by step guide to follow. it will help with the removal and installation of your new clutch.

Remove the Old Clutch Step1 Verify that your vehicle's clutch is the source of your problems and not the pedal-arm bushings, activating cables or the slave-master cylinder. Step2 Unhook the positive battery cable, the clutch cable or hydraulic slave cylinder to get the transaxle ready for easy removal. Eliminate anything that may hinder your efforts, including exhaust pipes and the speedometer. Step3 Secure your car in a safe position before jacking up the front end. Step4 Stabilize the engine with a jack below the oil pan. Remove the transaxle by undoing at least one engine mount. Step5 Separate the engine from the transaxle by removing the bolts that surround the flywheel bell housing. Step6 Push the transaxle away from the engine until the input shift clears the pressure plate. Step7 Disengage the bolts surrounding the pressure plate and take it and the clutch disc out. Check to see if the flywheel's friction surface is scored, checked or has hot spots. Remove, machine and reinstall the flywheel, if needed. Step8 Examine the pilot bearing (bushing) located at the flywheel's center to be sure the needle bearings are lubricated and that there's no galling. Also look for any oil leaking around the rear main engine seal. Replace the clutch Step1 Follow the instructions for replacing your car's clutch carefully to avoid having to remove the transaxle. Step2 Check that the transaxle's input shaft isn't leaking; replace if needed. Step3 Take out the flywheel and the old seal and install a new seal. Install a New Clutch Step1 Clean the crankshaft flange before putting in the flywheel. With the flywheel on top of the flange, secure the bolts in a star formation to the specified torque for your vehicle. Step2 Install the clutch disc and pressure plate. Prior to putting in the transaxle, attach the new release bearing to the release fork. The fork should move freely. Step3 Hoist the transaxle into position and move it forward until the input shaft glides into the clutch disc's spindled hole. Do not apply force. Step4 Reinstall any bolts or mounts that were removed to replace your car's clutch. Grab the transaxle, release the jack and lower your vehicle. Step5 Consider replacing your car's clutch cable. If you don't replace the cable at least adjust it for the right amount of free-play. Step6 Confirm that your clutch's self-adjusting action is performing correctly by depressing the slave cylinder's piston into its bore. Step7 Drive your car to be sure your clutch is working properly.
