Crankshaft seals are durable and last the life of an engine. . Step 41: Install Reluctor Wheel Important! Gently run these bolts down until gaskets and cover are flush, then use the following torque readings: bolts 1 through 7, 15 to 22 ft-lbs; bolts 8 through 15, 30 to 41 ft-lbs. Windsor blocks employ dowels, which are installed when all main bearing caps are torqued to spec. These are in good condition and reusable, which saves the cost of new tensioners. Step 5: Set the Crankshaft Install the crankshaft but take extra care to observe crank-tobearing contact. Torque the exhaust manifold nuts.
Step 1: Romeo Main Caps Are a Jackscrew Design Torque Fasteners Romeo main caps use a jackscrew cross-bolt design. However, the basics are the same across the board from 1991—present. The seal lip always goes toward the inside. Rod Bolt Torque Angle Modular engine connecting rod bolts receive the torque-to-yield treatment for accurate bolt tension and stretch. The Windsor block has no jackscrew adjusters.
The number-5 main cap is not cross bolted from 1991—1995. Lay the gasket on the deck and make sure it is in the correct position. Torque the fasteners to 71 to 106 in-lbs using an 8-mm deep-well socket in a criss-cross fashion. Check endplay before side bolts are torqued, and then again after. Step 42: Torque Camshaft Sprockets Torque cam sprocket bolts to 30 ft-lbs with an 18-mm socket, plus 90 degrees for M10 engines. The 1991—1995 Romeo blocks have eight jackscrews and cross bolts. Step 4: Apply Engine Assembly Lube to Main Bearings Important! Gasket contact surfaces need to be hospital clean and without debris, including old gasket material.
Now install the timing cover, cam covers, induction system, exhaust manifolds or headers, and all electronics Close attention needs to be paid to things that can leak. The Modular oil pump must be primed. However, take nothing for granted in your installation. All you need are two Modular engine roller rocker arms and some. These jackscrews unscrew outward to contact the block when torqued. If you have a crankshaft that wanders in the block more than. Proper fastener function requires proper tension.
Step 37: Install Crank Gears Install the crank gears first, with shoulders toward the timing cover. Step 2: Windsor Main Caps are a DowelPin Design Important! You degree camshafts to learn piston position and valve timing events. Cam cover gaskets are molded silicone strips that fit in grooves. If the torque reading is inaccurate you could cause major damage. Windsor main caps have a provision for dowel pins instead of jackscrews as you see on Romeo blocks.
Step 52: Install Intake Manifold Gaskets Use alignment pins for security when you install the intake manifold gaskets. Pistons are a smooth press fit this way. I recommend checking all eight and recording the measurements. Loosen all head bolts a minimum of one full turn. Torque the manifold bolts carefully to 18 ft-lbs. Bolt threads should be lubricated with moly lube or engine oil.
Make sure all contact surfaces are clean. Replacing the belt before it breaks saves your engine from further damage to pistons, water pump and valves. We understand how frustrating an improperly running vehicle is and want to help you get on your way. Step 26: Install New Core Plugs Block core plugs should always be replaced. The trigger wheel is pre-2001. Torque Windsor cross bolts to 20 to 24 ft-lbs, and then 85 to 95 degrees with a torque-angle gauge.
Apply generous amounts of assembly lube between the bearing and the crankshaft journal. Shipping And Handling Policy The buyer is responsible for any applicable import duties and local taxes. This is why the Modular engine employs torqueto-yield fastener technique. Position the seal lip toward the inside. I like this yellow sealer called Gaskacinch. This gets your Modular engine off to a fresh start with electronic engine control that does what it was designed to do.
