  Q: What are the steps and considerations for refitting a flywheel drive plate and its retaining bolts except GDI engine on Volvo V40?

  A:

  New flywheel drive plate retaining bolts will be required for refitting. To remove the flywheel, first remove the transmission and the clutch assembly and make alignment marks for proper refitting. Unbolt the flywheel, which may be tight with thread-locking compound, and prevent rotation of the crankshaft by inserting a large screwdriver in the teeth of the ring gear against an adjacent dowel. Every discard the old flywheel bolts as they are subject to great loads and should not be reused. For the driveplate, remove the automatic transmission and make some alignment marks, and unbolt the driveplate while ensuring that the crankshaft does not rotate, but be sure that the driveplate bolts used by the old automatic transmission are not reused. During inspection, look for damage to the flywheel's clutch mating surface, and surface grind or renew if necessary. For automatic transmission models, check the torque converter driveplate for distortion, cracks and wear; renewal is necessary in the case of any discovered damage. For refitting the flywheel, clean the mating surfaces and remove any locking compound from the crankshaft holes and then perform the removal operations in the reverse order, being sure to locate the flywheel by a roll-pin and use thread locking fluid on the new retaining bolts before tightening them to the specified torque and angle. Finally refit the clutch and transmission and for the driveplate the same procedure as for the manual transmission models, without any references to the clutch and fit the transmission.

  Q: How to remove and refit the transmission and flywheel correctly for GDI engine on Volvo V40?

  A:

  To remove the transmission, first remove the clutch assembly. The flywheel has a certain orientation, so if you make marks of alignment, it will be easier to position the flywheel for easier refitting. Note the sequence of the various spacer plates on either side of the flywheel upon removal. Unbolt and remove flywheel, which may require some force because of thread locking compound; prevent crankshaft rotation by placing a large screwdriver in teeth of ring gear next to a dowel. Handle the heavy flywheel carefully so as not to damage the ring gear. Inspect the flywheel for any heavy scoring, cracks, or damage, which, if found, calls for a need to renew it, but surface grinding may be an option. Check the condition of the old flywheel bolts once removed, making sure to cleanup any locking compound and inspect the threads as reusing them can be dangerous because of high service loads, new bolts are recommended. Do not disturb the six factory-fitted bolts surrounding the flywheel's outer edge because they are for balancing. For refitting, wipe the mating surfaces and wipe out any leftover locking compound from the holes in the crankshaft. It is recommended that the underside of the bolt heads be oiled, and the threads coated with a locking fluid, but it is necessary to be careful not to mix the two. Position the flywheel and spacer plates according to the alignment marks and insert the bolts and tighten them finger tight. Make sure to lock the flywheel so it does not turn and tighten the bolts in diagonal order to the specified torque before refitting the clutch and transmission.
