If you run a modern Scania from the new generation range, you’ll know that clutches take a beating. These trucks handle heavy loads, high torque, and long hours, and eventually every clutch reaches the end of its life. The Scania G410 XT is no exception.
In this article, we’ll go through what’s involved in replacing a clutch on a Scania New Gen G410 XT, what tools are needed, common mistakes to avoid, and how long the job really takes. You can also watch the full process in our video here:
🧭 Why the Clutch Matters on Scania New Gen Trucks
The clutch on a modern Scania is designed to handle serious torque and high mileage while still delivering smooth gear changes. When it starts to slip, drag, or make gear selection difficult, it’s not something you can ignore. A worn clutch affects power delivery, fuel efficiency, and ultimately your gearbox life.
A correctly fitted clutch ensures smooth performance, consistent engagement, and minimal wear on transmission components.
🧰 Tools and Parts You’ll Need
Genuine or high-quality clutch kit compatible with the Scania New Gen (pressure plate, friction disc, and release bearing)
Heavy-duty transmission jack or lifting cradle for gearbox removal
Torque wrench for accurate tightening of bolts
Clutch alignment tool
Engine support bar or mounts
Cleaning supplies and degreaser
Replacement seals or gaskets for the gearbox input shaft
Gearbox oil and general workshop safety equipment
⚙️ Step-by-Step: How to Replace a Scania G410 XT Clutch
1. Preparation and Safety
Park the vehicle on level ground and secure it. Engage the parking brakes, chock the wheels, and disconnect the battery. Remove covers, air lines, or exhaust sections if needed to create room. Always make sure the vehicle is safely supported before starting work.
2. Accessing the Clutch
Support the gearbox with a transmission jack and disconnect linkages, air lines, and wiring. Remove the prop shaft and separate the gearbox from the engine. Once it’s free, lower the gearbox carefully to expose the clutch assembly.
3. Inspecting the Flywheel
With the clutch removed, inspect the flywheel for heat marks, scoring, or cracks. If it’s damaged or worn, replace or skim it before installing the new clutch. Clean everything thoroughly so the new parts have a perfect surface to work against.
4. Removing the Old Clutch
Undo the clutch cover bolts in a cross pattern and remove the old pressure plate and friction disc. Check the input shaft for play or oil leaks. Replace any worn seals and clean the bell housing area completely.
5. Installing the New Clutch
Use a proper clutch alignment tool to position the new friction plate correctly. Fit the pressure plate and tighten the bolts evenly to Scania’s torque settings. Make sure the release bearing is installed smoothly and that all moving parts are lubricated where required.
6. Reinstalling the Gearbox
Lift the gearbox carefully back into position, aligning the input shaft with the clutch spline. Reconnect all linkages, air lines, electrical connections, and the prop shaft. Refill gearbox oil if drained and torque all fixings to specification.
7. Final Checks and Testing
Start the engine and test clutch engagement. The pedal should feel firm but smooth, and the truck should move off without slipping or dragging. After a short test drive, check for leaks, vibrations, or unusual noises and recheck bolt torques.
🧠 Common Mistakes to Avoid
Contamination
Any oil or grease on the friction plate will ruin the new clutch quickly. Keep all contact surfaces clean.
Incorrect Torque Settings
Over- or under-tightening bolts can lead to imbalance or premature wear. Always follow Scania’s torque chart.
Poor Alignment
If the clutch isn’t cantered properly, it will cause difficulty engaging gears and can damage the gearbox input shaft.
Ignoring Related Components
Replace the release bearing, input shaft seal, and check the flywheel each time. Reusing old parts often leads to early failure.
Skipping the Break-In Period
A new clutch needs a few hundred miles of gentle use to bed in correctly.
❓ Common Questions About Scania Clutches
How long should a Scania clutch last?
It depends on the load and driving style, but typically between 300,000 and 500,000 km before noticeable wear.
What are the signs of clutch wear?
Slipping when accelerating, trouble selecting gears, a heavy pedal, or a burning smell under load are all signs of a worn clutch.
How long does a clutch replacement take?
Usually a full day in the workshop. The gearbox is heavy and precise alignment is required.
Can I reuse old components?
It’s not recommended. Always replace the full kit including the bearing and check the flywheel surface.
🧩 Final Thoughts
Replacing a clutch on a Scania G410 XT isn’t a quick job, but when done correctly, it restores the truck’s performance and ensures smooth, reliable gear changes. Proper tools, clean work, and attention to detail make all the difference.
