  Q: How to remove and replace the clutch disc and pressure plate on Mercury Milan?

  A: The first step to replace and remove the clutch disc and pressure plate requires removal of the transaxle along with an inspection of the clutch pressure plate for discoloration and both scoring and bent segments in its diaphragm spring fingers. The Dial Indicator Gauge with its Holding Fixture should be used to measure Flywheel rotation while confirming that deviating spring ends remain within a maximum specification of 0.6 mm (0.02 in). Utilize a Flywheel Holding Tool to lock the flywheel on the engine before loosening the bolts in a star formation until the spring tension becomes free. Use a appropriate clutch disc aligner to extract all parts including bolts, clutch pressure plate and clutch disc. The clutch pressure plate requires cleaning with a suitable cleaning solution yet should not be submerged in solvents while an inspection must determine if the surface shows burn damage and flatness and scores and ridges and cracks with a maximum flatness clearance of 0.3 mm (0.012 in). The saturation of oil in the clutch disc requires investigation of the rear engine crankshaft seal or transmission input shaft seal for possible leakage and necessitates replacement if needed. Emery cloth should smooth out any small imperfections on the clutch disc lining while the inspections must check for oil saturation and worn facings, warpage, and rust on the splines which will require a new clutch disc if such issues are detected. Measure clutch disc runout options while completing the exam for Flywheel Runout Check if required. Under pressure examination of the clutch release bearing should verify its smooth operation while checking for signs of wear or damage. Examine the clutch release bearing guide tube for signs of wear while checking the clutch release fork for any type of damage. The installation requires application of grease to the clutch disc hub followed by disc placement on the flywheel through use of a suitable aligner. Start with placing the clutch pressure plate on the flywheel before installing 6 bolts. Tighten them following a star pattern at 29 Nm (21 lb-ft). Add grease to the clutch release fork fingers along with clutch spring and guide tube and Clutch Slave Cylinder end adjacent to the release fork faces. The procedure ends with reinstallation of the transaxle followed by applying small grease amounts to transmission input shaft end and splines.
