  Q: How to properly replace a front crankshaft seal on Mitsubishi Montero?

  A:

  Take off the crankshaft pulley and remove the drivebelts. Cautiously lift the seal out of the front cover with a seal removal tool or screwdriver without scratching the seal bore or damaging the crankshaft as any damage can cause leaks with the new seal. Wipe the bore in the timing chain cover, and apply engine oil or multipurpose grease to the outer edge of the new seal. With a socket whose outside diameter is a little less than the seal, carefully push the seal into position with a hammer; in the absence of a socket, a short piece of a large diameter pipe may be employed. Check to determine whether the spring has popped out after installation. Lastly, fit the crankshaft pulley, start the engine and check whether there are leaks.

  Q: How to replace the rear crankshaft seal on Mitsubishi Montero?

  A:

  To conduct this procedure, the transmission needs to be removed from the vehicle. It is possible to replace the seal without removing the oil pan or seal retainer; however, doing so is not recommended.These seals become very stiff, which means that they may not be put on properly or may get damaged in the process. If you do go ahead, remove the old seal and put a smear of clean oil on the crankshaft seal journal and the lip of the new seal, and tap it in. The stiff lip must be worked onto the crankshaft's seal journal with a smooth object as the seal is tapped in, taking care not to get stuck. One suggested way is to remove the oil pan and seal retainer. Once the oil pan is removed, take off the seal retainer and remove all old gasket material. On a workbench, on some wood blocks, position the seal and retainer assembly. Drive the old seal out from the back side using a punch and hammer. Use a wooden block or a section of pipe to drive the new seal into the retainer, ensuring the seal is not cocked in the retainer bore. After lubricating the crankshaft seal journal, as well as the lip of the new seal with clean engine oil, place a new gasket on the engine block. Gently push the seal onto the crankshaft with something smooth while pushing the retainer against the block. Ensure that the retainer bolts are installed and tightened to the specified torque, with the lower sealing flange of the retainer not extending below the lower sealing flange of the block. Reverse order of removal is followed for the remaining steps; after completion, start the engine and look for oil leaks.
