Chrysler Dodge 251 Straight-6 Flathead Spitfire Engine Rebuild. The tangs of the fork go between the coils of the spring and locate in the machined groove in the bottom of the guide. The some procedure is fol-lowed for the other pump: Lay down a neat bead of silicone all around the gasket surface and around the bolt holes. Advantages of a flathead (side-valve) engine over an OHV (overhead valve) engine were cost of manufacture and simplicity. To adjust the valves, reinsert the punch into the hole in the guide boss to locate the lifter. Tubes, dipsticks, and elbows are available from Van Pelt Sales. Each valve has its own camshaft. Don’t keep hammering “just to be on the safe side.”. The breather cap must have the cutout also facing front. If you lay down a neat bead, you’ll have minimal excess to wipe away. You’d be surprised how many times you get it wrong using a worn-out balancer or … [Click here to read more...], Parts selection is one of the most important elements of engine building because all parts must operate in concert with one another. Do not mix and try to match. Mike’s choice for engine oil is Valvoline VR1 20-50. The Merc equivalent is a similar design in stamped steel. Fits various models of 6 cylinder Truck “L” head and Industrial applications. Correctly adjusting the valves on a flathead is a finicky process and is done while the engine is cold. New bearings are available if either your bearing or your bushing is overly worn. The two cam gears and the distributor drive gear are pre-lubed with engine assembly grease. The bearing tang should always face the pan rails. In this case, it’s more or less stock and has a single carb. The deflector is in position. Use a brass drift and a dead-blow hammer to insert the woodruff key into the crank snout. Bolt the cover in place using five cap screws with lock washers. Torque the rear main fi rst, the front main second, and the center main last. Next, I assemble all of the tools I’m going to need and the various chemicals necessary for assembly. Initially, the valve, guide, retainer, and keepers are assembled without the spring, because it must be measured for spring length with the valves installed in the block. The parts consist of the bushing, the gear, a gasket, and the cover. The kit contains bearings, but I left those out and used some dry Boca ceramics from stock instead. Note that plenty of engine assembly lube is used on the bearing surfaces. The bearing tang is on the inside. Somebody might have abandoned a rebuild and returned the bearing in less-than-perfect condition. After cleaning, the fi lter screen was installed into the oil pickup and secured with the wire clip. Poor preparation also makes for mistakes. A micrometer is used to measure the distance between the spring seat and the spring keeper. The punch drops into the slot in the lifter and enables you to secure the lifter while you make the adjustment. The side slots both lighten the lifter and give you purchase for adjustment. The eponymous flat cylinder heads that give the engine it’s name, printed in red PLA, took about 10 hours each. Simple is not the word: The screen hooks in on one side and clips into the other. The inspection plate also has a drain plug. Use a pickle fork to compress the spring. This layout came about because the inlet and exhaust valve stems on each cylinder are parallel to each other and about two inches apart. Use plenty of assembly grease. It provides better sealing and less slap. Some info on the Ford Flathead V8 from Wikipedia: “The Ford flathead V8 (often called simply the Ford flathead, flathead Ford, or flatty when the context is implicit, such as in hot-rodding) is a V8 engine of the valve-in-block type designed by the Ford Motor Company and built by Ford and various licensees. Hammer the bushing home. After making sure that the gasket is a good fit and doesn’t obstruct any bolt holes or ports, spread more silicone carefully, lightly, and evenly around the gasket surface. The car tube positions the pickup in the center of the engine. Mike lifts the crank into the block. Push them down until the tip of the valve bottoms out on the lifter-adjusting bolt. If you want all the premium wiring diagrams … From Wikipedia, the free encyclopedia The Ford flathead V8 (often called simply the Ford flathead, flathead Ford, or flatty when the context is implicit, such as in hot-rodding) is a V8 engine with a flat cylinder head designed by the Ford Motor Company and built by Ford and various licensees. There were essentially three generations of the Flathead, easily distinguished by the number of studs that held the heads to the cylinders. Torque values and tightening sequence diagrams for stock Ford/Mercury engines (note that some other torque … The front pulley locating key was installed earlier. It can be magnetic as a safety measure. This is the hardware kit from MakerRX that is made specifically for this engine: https://www.makerrx.com/products/mrx5. They were generally set for timing in a special fixture, but can be set in this way too. The assembled valves and springs are lined up and ready for installation. The black needle of the spring scale indicates 80 pounds of preload with two shims inserted below the spring, which is acceptable. Use a thin, open-ended wrench to turn the lifter adjuster screw. When it debuted, it was the first of its kind to have the cylinder and block cast as one single piece.

The tang in the bearing goes into the recess in the block. Later blocks had bolts instead of studs. A small “F” is stamped on the front of the deflectors. Remember the cast pot metal rear oil slinger that was saved from the teardown? When the spring is inserted into the spring gauge and compressed to the required length (shown on the ruler next to the spring), the spring should have about 70 pounds of preload. Located in the timing cover and likewise cut a little long, it is also liberally coated in engine assembly grease. Hammer them home gently but firmly. Don’t forget the distributor hold-down; it is secured by one bolt. The Ford Flathead is a valve-in-block engine and the valves open adjacent to the combustion chamber, rather than from the top, as in later engines. Finally, I clean up my work area and have as much equipment as possible at hand so that I’m not forever looking for things.
