1985 -1995 5.0L Ford V8s with Hydraulic Roller Lifter Cams ACCU-DRIVE CAM GEAR DRIVE SYSTEM Installation Manual

1. Remove stock timing cover. Rotate engine to Top Dead Center of cylinder #1 so that the timing marks on the original crank and cam sprockets are directly lined up with each other, i.e. the mark on the crank sprocket will be straight up and the mark on the cam sprocket will be straight down. Using suitable gear puller, remove stock crank and camshaft sprockets and timing chain. Refer to repair manual if necessary for individual steps. 2. Assemble Accu-Drive as shown in Figure 1. 3. Install crank gear with the large inside chamfer toward rear of engine and timing mark toward front of engine. Make certain crankshaft drive key is aligned with keyway of the crank gear before assembling. 4. See Figure 2 “Camshaft Gear Assembly”for correct assembly. (a) Place well-lubricated thrust washer on the rear (block) side of cam gear. (b) The Edelbrock Accu-Drive system is furnished with an 0.032″ thick thrust ring that installs between the back side of the cam gear and the front side of the camshaft thrust plate. Torque the thrust plate retaining capscrews to 9-12 ft./lbs. NOTE: No thrust button is used on Ford engines. (c) Select the desired keyway in the crank gear “0″ (standard), “A” (4ºadvanced at the crank, 2º at the cam), or “R” Place a small amount of clay on the front end of both axles as shown in Figure 3. NOTE: It will be necessary to cut material off rib inside front cover to hold idler gears in place. (b) Install front cover with gasket in place. (c) Remove cover and measure the thickness of the compressed clay. It should be .005″-.030″. Do not tighten cover down until proper clearance has been obtained. Without sufficient clearance, there is risk of cracking the cover when tightened down. (d) If clearance is less than .005, you will need to grind off idler axle as shown to obtain proper clearance. If clearance is greater than .090, replace left side (larger idler side) stud with tapered end axle provided in the kit. Re-install idler assembly and recheck for minimum clearance between block and front cover. 8. With all gears correctly in mesh and timed, tighten the camshaft capscrew to 35 ft./lbs. It would also be a good idea to use Locktite™ or equivalent on the bolt threads prior to final assembly. 9. Lubricate all gears and bearings with engine oil. 10. Re-install the front cover. 11. Re-install all components removed in preparation for step 1

1996 Ford Taurus Camshaft Position Sensor removal and installation manual

REMOVAL CAUTION: Prior to removal of the Camshaft Position (CMP) sensor, set cylinder No.1 to zero degrees Top Dead Center (TDC) of compression stroke. Then note the position of the CMP sensor electrical connector. The installation procedure requires that the connector be located in the same position. 1. Disconnect battery ground cable. NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the Powertrain Control Module (PCM) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy. 2. Disconnect engine control sensor wiring connector from CMP sensor. 3. Remove retaining screws and CMP sensor from sensor housing. 4. If removing CMP sensor housing from the cylinder block, proceed with Removal Step 5. If not removing sensor housing, proceed to installation Step 6. 5. Remove hold-down clamp (bolt and washer assembly) . 6. Remove CMP sensor housing from cylinder block INSTALLATION CAUTION : A special service tool such as Syncro Positioning Tool T95T-12200-A must be obtained prior to installation of the replacement CMP sensor. Failure to follow this procedure will result in improper sensor alignment. This will result in the fuel system being out of time with the engine, possibly causing engine damage. 1. Attach Syncro Positioning Tool T95T-12200-A as follows: a. Engage CMP sensor housing vane into the radial slot of the tool. b. Rotate tool on CMP sensor housing until tool boss engages notch in sensor housing. 2. Pre-lubricate synchronizer gear with engine oil meeting Ford specification ESE-M2C123-A prior to assembly. 3. Install sensor housing so that drive gear engagement occurs when arrow on ocator tool is pointed approximately 75 degrees counterclockwise from the rear face of the cylinder block. This step will locate CMP sensor electrical connector in the pre-removal position. 4. Rotate Syncro Positioning Tool T95T-12200-A clockwise slightly. This will engage oil pump intermediate shaft. Push downward while adjusting Syncro Positioning Tool T95T-12200-A until the Syncro Gear engages the camshaft gear. 5. When synchronizer flange is fully seated against block, the installation tool should be facing counterclockwise of engine centerline approximately 33 to 45 degrees. 6. Install hold-down clamp (washer and bolt) and tighten bolt to 19-30 Nm (14- 22 lb ft)

Ford V8 Engines Performer RPM Hydraulic Roller Camshaft INSTALLATION INSTRUCTIONS

Disconnect the battery. 2. Drain radiator coolant. Drain plug will normally be located on lower right or left side of the radiator facing the engine. 3. Remove radiator and air conditioning condenser if so equipped. In some cases, the front grill may have to be removed. Measure distance from front cover to grill or brackets that may interfere with camshaft against the length of the camshaft. 4. Remove the gas cap to relieve pressure. Disconnect fuel line and plug. Replace gas cap. 5. Disconnect all linkage from carburetor such as throttle, throttle springs, transmission, cruise control and automatic choke. 6. Tag and remove coil wires and sensor wires. 7. Tag and remove vacuum lines. 8. Remove valve covers. 9. Remove distributor cap and wires, rotate engine until rotor points towards number 1 terminal in cap and pointer on front cover is on top dead center (TDC) and remove distributor. (see Fig. 1) Note: Mark the approximate position of the distributor housing in relation to the manifold to assist in getting the distributor properly located during re-installation. 10. Remove carburetor and intake manifold. Remove and discard intake manifold gasket. 11. Remove rocker arms and pushrods. CAUTION: If your engine has non-adjustable rocker arms (1969-1/2 or later), you must install screw-in studs and high performance •VALVE SPRINGS CAUTION: WARNINGS ABOUT YOUR WARRANTY In order for this Performer RPM roller cam to be covered under ANY WARRANTY, you MUST use the correct Valve Springs. Failure to install the correct valve springs may cause lifters not to follow the cam lobes and damage engine parts. This camshaft is designed to function with valve springs that have a closed pressure of 110 lbs, open pressure of 320 lbs and a lift of .575″. Special H.P. retainers may be necessary with your installation for proper spring height. Do not use rotator type valve springs or retainers for this application. Note: Edelbrock Sure Seat Valve Springs #5762 are not recommended.  IMPORTANT NOTES AFFECTING YOUR WARRANTY CAM LOBE DAMAGE – Cam lobe wear is almost non-existent unless mismatched parts are used or installation of the cam and lifters is done improperly. Cam damage can result from the timing gear loosening due to improper torque on bolts. Bolts holding gear to camshaft should be torqued carefully and a locking compound applied to threads of bolts. Before installing your new Performer-RPM roller camshaft, check the gear drive on the distributor and oil pump for any signs of wear. If worn, be sure to replace with a new gear or you may wear out your camshaft prematurely. High-pressure oil pumps are not recommended with Performer RPM roller camshafts. Edelbrock camshafts are designed to use with Edelbrock timing chains.  CAM GEARS AND CAMSHAFT END PLAY- If cam gear becomes loose, the cam will slide back in the block, causing the lifters to hit the lobes next to them and also the cam bearing journals. If the engine is run after this happens, the bottom of the lifters and the sides of the lobes will become damaged. See Installation Instructions section for end play specifications.  LIFTERS Edelbrock offers a retrofit roller lifter kit for engines not originally equipped with roller lifters. Use part #97453. To install your roller lifters, use fresh clean oil on the lifter and the lifter bore just prior to installing. The guide bar (high side of tappet) must face the opposite side of block. See roller lifter instructions for additional information. ( Note: 289-302 engines require removal of the cylinder heads to provide enough clearance to install roller lifters, which are taller than standard hydraulic lifters.)  PUSHRODS AND ROCKER ARMS High performance pushrods, roller rocker arms and rocker studs are recommended for this installation. After the cam is installed and timed correctly (see Figure 2), it will be necessary to check each pushrod for correct lifter preload. INSTALLATION INSTRUCTIONS 1. Check lifters as covered in Lifters section. Coat cam lobes with fresh clean oil. Lube distributor drive of cam with assembly lube (supplied). 2. Install new camshaft. Re-install thrust plate with new sprockets and timing chain with timing marks lined up as recommended by factory specifications (See Figure 2). Reinstall the fuel pump eccentric before installing sprocket bolt and washer
