There can be a myriad of reasons for which you need to adjust your PTO clutch. And for different reasons, you need different solutions. But whatever the reason is, all of them are fixable. So, don’t panic and follow this discourse.

Why Does The PTO Clutch Need Adjustment?

The problem can very well be a simple one. For example, maybe your oil pressure level is too low, or there’s a bad connection between the clutch and the shaft. 

Whatever the cause may be, all of these problems are solvable. Check some of the following factors if a problem arises.

• Clutch won’t engage
• Irritating noise
• PTO shaft won’t turn

How To Adjust The PTO Clutch 1997 Mahindra Model 435D1?

Sooner or later, your PTO clutch is going to need some adjustment. So, to reduce the amount of wear and tear, it’s better to nip the problem in the bud.

1. Clutch Won’t Engage: Check the Voltage

Sometimes you’ll see that your clutch isn’t working correctly. There may not be any other symptoms; it just stopped engaging out of nowhere. Well, the problem may lie in the battery.

Pick up the owner’s manual and check the location of the battery on your equipment. Once located, use your voltmeter to check if the voltage is at proper levels. 

Chances are, it’s probably not. If there’s a lack of voltage, no matter how many times you try, your machine won’t be getting enough power to start.

You need to charge the battery if the voltmeter reads 12.5 or less. But if you see that the voltmeter indicates that the battery has enough power, check the in-line fuse. 

You should find it between the PTO clutch assembly and the electrical wiring. Unbolt the cap wires, and you should see the fuse filament. 

If the fuse is blown or black, you need to replace the fuse with the original amp rating. That should solve your problem.

2. Irritating Noise: Replace the PTO Belt

If your PTO clutch is engaging, but there’s an annoying noise every time you turn it on, there may be something wrong with the bearing, the flywheel, or the pulley belt. 

In most cases, it’s due to the last cause. If that’s the case, you’ll need to replace the belt.

You can do it yourself or get a mechanic to look at it. If you’ve decided to do it yourself, remove the ignition key and remove the ignition wire. Don’t forget to engage the parking brake. 

After prepping the car for maintenance, take off the belt covers. You’ll probably need a ⅜” wrench for this job. 

Once you’ve removed the belt covers, the belt should be next. Don’t get rid of it altogether, just from the spindle pulleys. 

Next, loosen it from the engine and idler pulleys. Now, the belt is ready to be replaced. Just repeat the above process to fix a new belt in the reverse direction.

3. PTO Shaft Won’t Turn: Exercise the Lever

Unless your PTO is a mechanical one, skip this part. However, for those of you who have an automatic PTO clutch, this part’s for you. 

If you see that the PTO light is coming on after engaging the PTO clutch, but the shaft isn’t turning, the problem is most likely the linkage between the lever and the clutch.

Take a look at the connection between the rear gearbox and the driveshaft. If the link is damaged or even worse, broken, you won’t have any control over the shaft. If the link is broken, disconnect the outer rod. Then, grab your vice grips and work the lever out.

But if the connection between the two pieces of equipment seems to be in a good shaft, your other option is to rotate the shaft by hand. You can tell it is in good condition if you can turn the pole in one direction but not the other.

How do I diagnose my PTO clutch 1997 mahindra model 435d1?

First, put two jacks on the front and the rear of the frame to keep it steady above the ground. Next, get a voltmeter to get the reading on your engine. If the output is at or below 12.5 volts, charge the battery.

If the in-line fuse is brown or black, replace it with another one with the same amperage rating as the original. 

Finally, plug the negative cable and ignition switch in with a socket. Please press the engagement lever and depress it a few times after starting the engine. Turn the machine on and off. 

Repeat this process a few times. Unless you face a problem in any of these steps, your PTO clutch is in good shape.
