The Moroso Dry Sump Oil Pump is designed to fit either 90° V-6, small or big block Chevrolets, and the only difference is the mounting holes. You can see that there are two sets of slotted holes on the mounting bracket, which attaches the pump to the engine block.

Camshaft timing belt must be replaced if cylinder head is to be removed or if drive gears, tensioner or coolant pump are to be replaced. Camshaft timing belts must be stored and handled with care. Always store a camshaft timing belt on its edge with a bend radius greater than 2.0″ (50 mm). DO NOT use a camshaft timing belt that has been twisted or bent double, as this will damage reinforcing fibers. DO NOT use a camshaft timing belt if debris other than belt dust is found in timing belt covers. DO NOT use a camshaft timing belt if partial engine seizure has occurred. DO NOT reuse a camshaft timing belt if mileage exceeds 45,000 miles. DO NOT use an oil or coolant contaminated timing belt (cause of contamination must be rectified).

REMOVAL INTERFERENCE ENGINE. In the event of Urning belt failure, it is probable that valve to piston damage has occurred. A compression test should be carried out on all cylinders before removing the cylinder head. 1. Disconnect the negative cable from the battery. 2. Remove: – alternator, – RH engine mounting bracket, – spark plugs. 3. Disconnect the engine wire from alternator bracket and adjusting bar. 4. Remove the No.2 timing belt cover. 5. Turn the crankshaft pulley (clockwise) and align its groove with the timing mark “O’ on the No.1 timing belt cover. 6. Check that the hole of the camshaft timing pulley is aligned with the timing mark on the bearing cap. If not, turn the camshaft one full

Moroso Crankshaft Wipers are designed so that they can be trimmed to fit the widest possible range of counter-weight, rod/stroke configurations. They are to be mounted to the starter side of the block only. The Moroso Crankshaft Wiper is engineered to clear assemblies down to 2.9 IN. of stroke using stock type rods. As the stroke is increased and /or larger rods used, the amount of material to be removed increases. Do not be alarmed at the amount of grinding and trimming with shears which may be necessary to clear your particular assembly. We recommend.030” to .045” clearance around all moving components. After you have trimmed your wiper, be sure to smooth all edges to prevent all potential engine damage due to burrs vibrating off into the crankcase. Before final assembly, double check for clearance when the crankshaft is rotated a full 360 degrees. Be sure to account for “thrust end play” while checking for proper clearance. After final fitting and deburring, cement the wiper to the block. You can use contact cement or weather-strip adhesive (An alternate method would be to use tiny flat head screws or pinning). Next, install the pan gaskets in the usual manner. Due to the slightly increased height on one side,
Be sure to use a dab of silicone in the corners where the rubber ends meet the side rail gaskets.

Preparing the Crankshaft and Convertor for Installation
• Always check the crankshaft pilot for burrs and out-of-round.
• Remove any rust with emery paper and lightly grease pocket receiving torque convertor pilot hub.
• Remove paint from the torque convertor’s crank pilot hub with emery paper.
• Before installation, pre-fit the torque convertor to the flex plate and into the back of the crankshaft. It should be a snug, even fit (not loose or binding).
• Slowly pour two quarts of automatic transmission fluid into the convertor.
• Check the flex plate for cracks or worn teeth.
• Replace the transmission front seal.
• Install the torque convertor on the front of the transmission.
• When installing the torque convertor into the transmission, you will feel it seat 3 times for the input shaft, shaft to stator, and oil pump notches.
