The LC Pro Crankshaft Scraper will decrease crank windage and drag by removing excess oil from the crankshaft while reducing oil foaming, producing increased horsepower and longevity.
1.Install crank scraper with the angled portion of the scraper on the exhaust side of the block, pointing towards the top of the block. With the crank and rods installed in block, rotate and check the clearance between crank/rods and scraper. Minimum clearance .100" required. Modify scraper accordingly.
2.On oil pans that use a silicone seal, apply a 5mm bead of silicone on both sides of the scraper and install the oil pan. Torque bolts to approx. 9 Ft.-Lbs.
3. On oil pans that use a gasket seal apply a 5mm bead of silicone on the block side of the scraper and use a gasket on the oil pan side of the scraper. Install oil pan and torque bolts to approx. 9 Ft.-Lbs.
4.Turn the engine over by hand to assure proper clearance.
***LC Engineering recommends using Ultra Grey silicone only.***
