Additionally, Ford made a 370 cubic inch 385 series available in medium duty trucks. The beam design is relatively simple, and is accurate for both left-hand and right-hand threading. The lower front bolts of the intake manifold in pre-1996 engines require 35 foot-pounds, the lower rear bolts require 41 foot-pounds, and the upper bolts require 10 foot-pounds of torque. Bolt Type: Dim: Length: Head: Grade: Oil Filter Adapter To Engine Block 13. Retighten them by turning through 45 Repeat step d once again.
As a simple rule of thumb, any fastener should be tightened as tight as possible without failure of the thread or the component parts. After 1998, the nuts and bolts of the oil pan attach to the engine block with 18 foot-pounds of torque. Slightly less desirable than the Boss 351, the 351 High Output used the spread bore bolt pattern cast iron manifold for the Autolite 4300-D. There are basically three types of torque wrenches, the beam type, the click type and the dial type. Wheel, Hub, Rear Cog Area Component Shimano® in-lb.
Torque wrenches available to general industrial work, including bicycle work, are typically accurate to plus or minus four percent. Torque is measured as a unit of force acting on a rotating lever of some set length. Generally, the higher the rotational resistance, the greater tension in the threaded fastener. Research by some have shown this to be a myth, although some builders still seek out the earlier 1971-'73 engines, just in case it's true. As time progressed, the 351 Cleveland made less horsepower until its demise in 1974. Common industry practice is resistance at lever half way through swing from open to fully closed.
Even if the bolt were as tight as possible, it would not provide enough force to hold the arm secure to the spindle. It is commonly believed that bolts and nuts often come loose for no apparent reason. After applying oil to cylinder head bolts, tighten them gradually as follows. Type: Dim: Length: Head: Grade: Oil Pan To Engine Block 7. As a fastener is tightened, the fastener actually flexes and stretches, much like a rubber band. Compare them and make your own decision as to which to use. Threaded fasteners nuts and bolts are used to hold many components to the bike.
The bicycle has relatively light torque specifications 20-inch pound to relatively heavy torque specifications 600 inch-pound. To use a 302 head on a 351, special intake gaskets are needed. It also had a tank mounted electric fuel pump because it ran out of gas at about 130 mph with the regular cam driven pump, so it didn't have a cam driven pump at all. These were some of the largest and heaviest V8 engines Ford has ever built. Tension in the fastener depends largely upon the amount of torque tightening and the size of the thread. Here are a few scans of instructions from Edelbrock that seems to be very usefull.
The amount of pressure applied by a thread can be substantial in order to hold the joint secure. This means the weakest part of the joint determines the limits of tension, and hence, torque. Additionally, factory service parts may be whatever is on the shelf, also not necessarily the current year. A 1972 vehicle just might have a 1970 coded engine part. These same type caps were later used on the Mexican 302 block. Bolt - Rod Cap Type: Dim: Length: Head: Grade: Crankshaft To Engine Block 75 Ft-Lbs 900 In-Lbs 101.
There are two 351W deck heights, 1969-1970 produced engines are 9. If the pointer is off to either side, the pointer beam can be bent back so it again points at zero. Tightening torque Lower crankcase bolt 10 mm 0. Loosen all bolts until tightening torque is reduced to 0 in reverse order of tightening. The crank-to-spindle interface receives quite a lot of stress, making larger threads M8, M12, M14 a better choice.
The mechanic must be aware of the purpose of torque, and what torque and fastener preload doing to the component joint. Also below you will find an video on the proper use of a torque wrench Best, Ken. A safe overbore is 0. Note that some companies do not specify torque for certain components or parts. Gasket Surface Flatness Intake Exhaust 58. The bolts of the oil pan in engines manufactured before 1996 require 8.
Tighten cylinder head bolts hex hole bolt to specified torque. Hello, Here are the instructions and diagram needed to get the job done. There are no easily interchangeable parts, although a hybrid can be built; sells heads for building a Clevor as well. Too much tightening will deform the threads or the parts. Runout Valve Tappet Or Lifter Collapsed Tappet Gap Standard Diameter Clearance To Bore 1 Hydraulic Lifter Leakdown Rate 1. Point arrow mark 2 on cap to crankshaft pulley side. Oil filter canister 25 lb.
