How to Recognize Manufactured by Sachs
Pressure plate with a position sensor - arrow - or Sachs written on it.
Check the Plastic Washer - A - Inside the Dual Mass Flywheel Manufactured by Sachs
• The red plastic washer - A - must be inside the dual mass flywheel. It must be under the copper-colored sliding washer - B - and above the shaft seal - C -.
• If the red plastic washer - A - is missing, then the dual mass flywheel must be replaced.
• Measure the wear on the plastic washer - A -
Measuring the Wear on the Plastic Washer Inside the Dual Mass Flywheel Manufactured by Sachs
- Clean the copper-colored sliding washer - A - and the shaft seal - B - at the measuring locations.
- Push the sliding washer - A - toward the shaft seal - B -.
- Measure the distance - x - from the top of the copper-colored sliding washer - A - to the top of the shaft seal - B - on the outer edge using the depth gauge.
• Dimension - x - minimum 2.5 mm
• If the dimension - x - is less than 2.5 mm, then the dual mass flywheel must be replaced.
Checking the Needle Bearing Inside the Dual Mass Flywheel on a 4-Cylinder TDI Vehicle: Vehicle (except on the 125 kW TDI)
Check which version of the needle bearing is inside the dual mass flywheel.
• Depending on the version of the needle bearing installed that have rollers or needle bearings missing every 4th roller. This does not mean that the needle bearing is faulty.
• Needle bearings is missing the 4th roller - arrows - must be replaced on 4-cylinder TDI vehicles (except 125 kW TDI). Refer to => [ Dual Mass Flywheel Needle Bearing, Sachs and LuK ] Dual Mass Flywheel Needle Bearing, Sachs and LuK.
• New needle bearings are equipped with rollers.
• On all other vehicles, the missing 4th roller is not a defect in the needle bearing. Do not replace the needle bearing!
Clutch Pressure Plate, Checking for Distortion, Cracks and Burn Marks
A Straight edge
B Feeler gauge
• Pressure plate deformation up to 1.0 mm is permitted.
Checking Ends of the Diaphragm Spring
• Wear up to maximum 0.3 mm is permitted.
Checking the Pull-Springs and Rivet Connection
I Pull-springs OK
• Slight offset in the outer area - arrows A -.
II Pull-springs damaged
• The pressure plate must be replaced if the pull-spring is bent or broken off - arrow B -.
- Make sure the rivet connections - arrows B - fit correctly on all pull-springs - A -.
• Replace any pressure plates that have loose rivet connections - arrow B -.
Checking the Metal Ring
- Check the metal ring inside the pressure plate for damage - arrow -.
• Replace any pressure plates that have a broken metal ring.
