In increasing number sequence (1-2-3-4), tighten the head bolt in three stages. 1. Tighten each bolt to 7-9 foot pounds of torque. 2, Tighten each bolt to 12-14 foot pounds of torque.
The bolt tightening sequence or torque sequence is defined in the torque tightening procedure. Most companies have their Flange bolt torque tightening procedure used during the plant`s construction and operation. Flange joints are torque tight with the help of a torque wrench (Manual or hydronic wrench).
Every bolt that you tighten, the head deforms. Microscopically, but it does. The torque sequence exists so that the head is deformed in way that once all bolts are tight, it`s flat. Tightening or loosening in the wrong order can create a pinching effect that can permanently warp or crack the head.
Tightening of the head bolts in the proper sequence ensures proper compression of the head gasket between the engine block and the cylinder head of the engine. Improper tightening of the head bolts can warp the cylinder head.
Set the torque wrench to 30% of full torque and, using the pattern, tighten each fastener. Repeat with the torque wrench at 60%. Repeat again with the torque wrench at 100%. Make a final pass, this time in a circumferential direction, ensuring each fastener is at the required torque.
To a new bolting apprentice, this may seem straightforward enough. But simply applying full torque to your first bolt and then moving onto the adjacent one is the wrong approach! The order in which you tighten the bolts and the load applied has a huge effect on the integrity of the joint.
Using this technique guarantees pressure is distributed equally between the bolts, thereby reducing any potential warping, loss of pre-load in a bolt, or damage to the gasket. The bolt tightening sequence also secures parts from coming loose, mitigating any risks of equipment damage and delay in daily operations.
Torque pattern is the proper tightening sequence so the bolts are properly stretched and can evenly carry the load. Whether there are four bolts or 12, torque pattern allows you to scatter the load.
Two principles influence the correct clamping pressure for each bolt, known as clamp load. The first is bolt diameter. The second is the class of the bolt, defined by the bolt`s tensile strength, which in turn is determined by the material of construction.
As with conventional bolts, torque to yield bolts are tightened in a series of stages and in sequence. Torque to yield bolts are generally tightened in sequence to what is known as a snug torque value. This snug value is to ensure that the component, in this case, say a cylinder head is firmly located on the block.
Criss-cross patterns are called out when tightening or loosening parts with a simple square pattern or circular bolt pattern. These basic patterns have been around for a very long time and are a proven method for evenly distributing clamping load across a part.
Bolts are designed to stretch as you torque them into place, and when you remove them, they snap back to their original position. Because of this, many standard head bolts are okay to use more than once, as long as they have not been stretched past their spring back point.
An engine`s power is the product of force and the speed with which this force acts. Engine power and torque are both indicators that depend on the engine speed. A high torque enables efficient and energy-saving driving. A high engine power enables a car to accelerate quickly and reach a high top speed.
Dial torque wrenches
They are considered the most accurate and are commonly used in the automotive, aerospace, and defense industries.
The torque and speed relationship is inversely proportional since the rated output power of a motor is a fixed value. As output speed increases, the available output torque decreases proportionately.
First, the size of the force matters. A larger force creates a larger torque. But the angle the torque makes with the radius also matters. Only perpendicular forces or the perpendicular component of a force can create a torque.
When attaching a wheel to a vehicle, torque specifications are the amount of force recommended on the hardware to ensure proper installation. Following exact torque specifications matters for a number of reasons. Too much torque can result in overtightening, which has significant consequences.
Torque tools are generally considered accurate within plus or minus 30%. That means if your target was 50 KSI of load, you could see anywhere between 35 KSI and 65 KSI bolt load on your fasteners, and you`d be okay with that.
The larger the bolt, the more torque is needed to achieve the necessary clamping force.
Traditional head bolts are tensioned to a predetermined torque measured by a torque wrench. This torque reading is not an accurate measurement of the downward clamping load but rather an accumulated measurement of friction resistance between the two threads and the spot face and bolt head and the clamping pressure.
Torque is the cross product of distance between point of application of force and center and force. = r * F * sin (theta) Here maximum value of torque is r*F because we know sin(theta) has maximum value of 1….where theta =90 degree. Hence torque is maximum when theta = 90 degree.
Is it better to apply torque to the bolt head or the nut? In general, there is no difference between applying torque to the bolt or nut. There are, however, situations where it would matter such as: If the through-hole produces interference – then it would be better to apply torque to the nut side of the joint.
Tighten lug nuts in a star pattern to ensure they are evenly torqued to eliminate vibrations. DO NOT use an impact gun/wrench. It WILL damage the finish of the lug nuts.
The Bike Technicians Tactic Phase1 An electrical inspection on the bike should produce results. First, the bike battery powers the entire lightening systems mentionable as ignition, meter readings, head lamps, signal indicators. However, the battery provides the power supply to several entities though also significant is the fuse box containing circuit protection coils. Inserting the bike key into the ignition to perform start mode displays the capacity power circuits. A charged battery should display an indication in the meter reading area also known as bike dashboard grading. A malfunctioning start mode on inserting key in ignition may be traceable several locations on the electrical circuits. Attempting to repair the electrical power of the bike usually requires batter power power test kit. The test kit ascertains the battery power making possible progress to the remaining electrical circuits. Test kit also ascertains the fuse box circuit functionality either with fuses still intact or extracted allowing for the next progress level. An observation tour of the bikes electrical wiring kits from battery hold through fuse box compartments to each lightening display area either headlamps, indicators, and meter reading should produce results of any visible damages that may require repairs after the electrical inspection has been performed. Once any faults were observed on the electrical channels, repair mode is the next level. A dull battery either may have been depleted completely of durational capacity requiring another for replacement. Alternately, a depleted power supply due to prolonged storage may require charge functionalities. Usually, a device capacapble of restoring a battery of electrolytes is resorted for charger ability. The type of battery may require constuents either liquid cathode replenishment in the battery entrapment area prior to charging feature is assumed with electrolyte machine. Once the battery has regained full functionality makes way the next repair task. The fuse box may have simply required replacement fuses either as missing or burnt out. A fuse box usually contains additional spare for replacement functionalities. An alternate arrangement at acquiring fuses on the auto mart may replace the burnt devices. The next electrical task is wiring fixtures achievable by mending broken cords with appropriate electrician’s tapes else malfunctions may remain. Alternately, a worn-out electrical wire is replaceable by acquiring the entire extension lengthwise between significant areas. The last remaining electrical units are lightening indicators consisting of bulbs or luminescent displays reflectors. Observe the blub areas either by loosening covers to inspect for observable burnouts else the entire electrical circuitry is ready for functionality observations with separate entities. Engine Technicians Tactic PHASE 2 A bike engine inspection includes observation for indications of malfunction. Any fluid residue is indication of problem areas. Where oil leaks usually requires engine block inspections. A bike engine consists of an entrapment compartment where mechanical combustion takes place. First, the entire observable block consists of an external coating known as engine bloc housing internal component of pistons, rings, and fastens known as cylinder heads. A bike engine has every component embedded within requiring technical expertise to achieve an inspection. Once deciding on the engine task requirements, acquire a tool box with the appropriate componements as first requirement before engine works is commence able. Second, the bike may require an area environment as workshop requirement to attain engine inspections. Third, bike engine are least bulky compared with vehicle engines however assistance would complement the inspection phase. Prior to inspecting the bike engine, a strap mechanism has to be assumed to achieve expert maneuverability also as safe precaution. Unless parts hinder maneuverability at engine locations, the only removable components should be the engine. First, start with disjointing the spark plug cables to acquire accessibility to plugs imbedded on the cylinder heads. The plugs require tools to loosen thereby exposing the combustible area. Once the spark plugs are exposed, two alternatives are likely. First, a spark plug may have gathered rust residue only requiring cleaning to attain regular capacity. The pin area of the spark plug may have been twisted due to overheating and slight melting dislocation. Usually cleaning the residue from old plugs may simply expose the ignitable capacities. However, an observation of twisted plug pin may require twisting back in place to achieve full ignitability once bike engine starts. A bike engine bloc has the pistons as combustibles or blasters of fuel gasoline. The rings perform as strap fasteners whenever the pistons move about combustibility. Usually, the engine entrapment components would have collected residue requiring clearing. Also, pistons together with rings may require replacements either as worn-out due to prolongs tasks or overexerted biker features.
