Re-Adjust The Clutch In Your Semi-Truck With A Buddy

If your clutch pedal on your semi-truck is hard to push in, that is one sign you need to readjust the clutch. If you hear the gears grinding every time you change gears, that is another good sign that you need to readjust your clutch. You can readjust your clutch on your own with the help of a friend, or you can take it into a local mechanic like South Pro Automotive Ltd to get the job done.

Remove The Inspection Cover Plate

First, you will need to get down and remove the inspection cover plate. This plate is located at the bottom of your transmission's clutch housing.

Watch Out For Metal

Once you remove this cover, use a rag to clean off any grease that is present. This will make it easier for you to work on. While you clean it off, you should also keep an eye out for any metal chunks.

If you see pieces of metal in your clutch house, you should close it up and take it to a mechanic. Loose metal is a sign that your clutch is failing and needs replaced. If you don't find any loose metal, you can proceed with adjusting your clutch.

Tighten Up The Adjustor Bolt Head

Have a friend sit in your truck and push in the clutch. Your friend will need to push the clutch all the way down and hold it there while you complete this next step.

You will need to place a 5/8'' socket on the adjuster bolt head. Then you will need to use a screwdriver to tighten the bolt. You will need to turn it to the right until the bolt pops out to the lock position.

Now, ask your friend to let off the clutch. Use a three or four inch long bolt with a ½ inch head to figure out if the adjustment worked. The bolt should fit between the space and the bearing. If it fits loosely between these two, then you have fixed the clutch.

Check The Free Travel Space

Next, have your friend push in the clutch and guess how much free travel space they have. That is how far one can push in the clutch before you start to feel pressure. Generally, you should have at least two inches of space before you feel pressure with the pedal. If there is too much free space, adjust the linkage until it feels right.

Now, all you need to do is reattach the inspection cover plate, and you are ready to get back on the road. If you run into any problems along the way, take your truck into a mechanic for help.
