2. Note the location of the old oil seal, then use a screwdriver to remove it from the casing.
3. Remove the spacer gasket from the crankshaft, remembering its location.
4. Inspect the spacer gasket and use emery cloth to remove any burrs or rough spots that could cause damage to the new seal. If necessary, the spacer gasket can be installed so that the new seal contacts an unworn area. Clean the seal contact surface in the housing.
5. Lubricate the sealing lips and outer edge of the new oil seal and install it on the crankshaft, closed side out. Press the oil seal lightly into the housing by hand, then use a socket or metal pipe to drive it in to the previously marked depth - work very carefully so as not to damage the lips of the oil seal.
6. Place the spacer gasket on the crankshaft and carefully insert it into the seal using circular movements.
7. Wipe off excess oil, then install the crankshaft timing gear and new timing belt, refer to Sections Removal, inspection and installation of the toothed drive belt and Removal, inspection and installation of the drive belt toothed wheel and tensioner mechanism.
Flywheel side oil seal
1. To replace the left crankshaft oil seal, the engine and transmission assembly must be removed. The engine must be separated from the transmission (refer to Chapter Transmission), clutch (where available, refer to Chapter Clutch) and flywheel/drive disc (refer to Section Removal, inspection and installation of flywheel/drive disk of this Chapter) must be removed.

2. Remove the old seal with a screwdriver, being careful not to damage the surface on the crankshaft. Alternatively, the seal can be removed in another way: drill two small holes in the seal opposite each other and screw self-tapping screws into them; now the seal can be removed with pliers.
3. Inspect the seal contact surface on the crankshaft. If it is rough or grooved in the area where the old seal was installed, the new seal should be installed at a slightly shallower depth so that it rubs on an unworn surface.
4. Wipe the contact surface with the seal, then dip the new seal into engine oil and place it on the crankshaft, closed side outward (refer to the accompanying illustration).
5. Using a metal tube, hammer the seal into place.
6. Install the flywheel/drive plate, refer to Section Removal, inspection and installation of flywheel/drive disk. Install the clutch as described in Chapter Clutch, connect the transmission to the engine and install the engine/transmission unit as described in the relevant Chapters of this Manual.
