Crankshaft Seals
Front and rear crankshaft oil seal should be changed each time the crankshaft or the packing flange. If you follow the above guidelines, you do not need a special tool to remove or install the crankshaft oil. Both of the gland can be replaced with the engine installed, if you notice traces of oil leaked near them. In addition, the crankshaft oil seal leakage may also indicate slipper clutch. In the worst case, oil spots in front of the engine may lead to slippage of the belt drive of auxiliary units, which can cause, for example, the loss of the charging power generator.
