• Tips to Carry Out Clutch Repair in Mercedes in Mountain View

    Mercedes Clutch

    Despite Mercedes-Benz durability and vehicle longevity, there are still vehicle parts that will need to be replaced simply from overuse. The clutch is a common vehicle part that will need to be replaced eventually. It gets used every time you drive, and the more miles it is used for, the more worn down it will become. If you find yourself in need of a new clutch in your Mercedes, it is recommended that you have it done by a professional. However, if you find the time and have the necessary knowledge, you may want to repair or replace the clutch yourself.

    Things To Consider Before Performing Clutch Repair

    One thing to keep in mind with clutch replacement is that it can be a lengthy process. Even shops that specialize in Mercedes vehicles can take up to 7 hours to perform the task properly.

    With that in mind, we recommend that you have at least two transmission jacks. Four is preferable, but two can work with some rope to support the subframe. The repair is also made easier with a two-post ramp. If you do not have these supplies at your disposal, then consider having the repair carried out with a trusted automotive professional.

    Follow the steps below to carry out a clutch replacement in a Mercedes:

    1. Open the hood and be sure to disconnect both battery terminals. This is a necessary step for your own safety. Remove the washer bottle for easy access, and then you will be able to undo the steering column assembly. Unlink the gear selector cables from the gear mechanism and be sure to completely remove them from the securing bracket.  Stowaway safely to one side.
    2. Disconnect the reverse light switch and remove the earth connection from the gearbox mount.
    3. You have no need to drain coolant or remove the radiator or fan assembly, so you will simply need to support them to the body using cable ties. Remove both front wheels, then raise the vehicle to full working height to be able to drain the gearbox oil.
    4. Remove the subframe protection covers from the left- and right-hand sides.
    5. Slacken the ball joints on both sides and then remove both brackets that hold the anti-roll bar in place.
    6. Remove the bracket that attaches the exhaust to the gearbox.
    7. Next, remove the left- and right-hand side brackets that attach the front bumper to the subframe, taking note that the right-hand bracket houses the ambient temperature sensor, which must be disconnected and safely stowed.
    8. Support the engine, gearbox, and subframe using four axle stands. Do this while removing the fixing bolts to the subframe.
    9. Remove the gearbox mounting nut and the two engine mounting nuts from the brackets attached to the subframe.
    10. At the rear of the subframe, you will find two further brackets that attach to the underside of the body that need to be removed on both sides. Remove the central through bolt, engine rear mount and gearbox rear mount.
    11. Remove six subframe bolts that attach to the body, and then remove the left- and right-side steering rack to subframe brackets.
    12. Remove the steering pump from the subframe by loosening the hexagonal bolt, and the pump will slide up from the bracket on the subframe. Undo the wheel arch liner flap on the left-hand side to expose two further bolts and the A/C pipe bracket and remove.
    13. Safely stow the power steering pipes, detach the steering rack from the subframe and carefully lower the front of the subframe using the two axle stands or a rope if you need as support.
    14. Release both ball joints. Carefully remove the complete subframe and move away and store safely from the work area.
    15. Support the steering rack and pump securely. Disconnect the hydraulic pipes for the CSC, before blanking and stowing away. Remove the gearbox mount bracket.
    16. Remove the bolts that secure the driveshaft to the gearbox and remove the drive shaft.
    17. Remove the starter motor bolts and stow to one side. It’s worth noting that the bolts for the starter motor are Torx bolts in most Mercedes models. Remove nine bolts that secure the bell housing, and carefully lower the gearbox and move away from the work area.

    Once you have established clearance and can access the clutch:

    1. You should be able to remove the clutch at this point.
    2. Once you have removed the clutch, you should also be checking of other extended wear, heat stress, or debris in or around neighboring vehicle parts such as the flywheel.
    3. Place a small amount of grease with a high-melting-point on the first motion shaft splines. After you’ve greased these parts, make sure the new plate slides easily back and forth to encourage the grease to spread evenly. Do not use a copper-based product for this step.
    4. Wipe away any excess grease away, especially from the shaft and driven plate hub. Use a universal alignment tool to check that the driven plate is facing the right way. The clutch can be bolted to the flywheel.
    5. Install the gearbox, ensuring that the bolts are secured and all mountings are refitted properly before removing the supporting transmission jacks. Refitting the rest of the components is simply following the reverse order of the removal.
