DisOWN the drivebelts Before removing the crankshaft pulley. Subsequently, take off the timing belt and the crankshaft sprocket from the crankshaft and also the inner belt guide. Using seal removal tool or a screwdriver insert the tool underneath the upper edge of seal and carefully manoeuvre it to release oil pump seal from the housing carefully so that it does not scratch the inner periphery of housing or the crankshaft as this will lead to oil leakage with the new seal inserted. Scrub the bore in the oil pump housing with a clean cloth andelseif using a new seal, apply engine oil or multi-purpose grease on the outer periphery of the seal. With the socket slightly less than the diameter of the seal, insert the seal gently with a hammer; in the absence of the socket one can facilitate the use of short pipe with large cross section, and then. As indicated at the end of the installation process, check whether the sealing has been effective on the part that had the spring with a view of establishing whether the latter popped out. Place the inner belt guide and the crankshaft sprocket and finally the timing belt. It is advisable to lubricate the sleeve of the crankshaft pulley with the engine oil or multi-purpose grease before fitting the crankshaft pulley and to refit the part in the reverse order to that, in which it was removed. Last but not the least, the best way to know whether there is leakage or not is to start the engine.
