Are LS crank bolts torque to yield?
It is essential when working on a GM LS engine to be aware that the cylinder head bolts are torque-to-yield (TTY) fasteners and cannot be re-used. Similarly, the connecting rod bolts are also TTY, however they can be tightened up to three times for bearing checking. Additionally, the balancer bolt is also a torque-to-yield fastener which must not be reused or over torqued. It is vital that these components are correctly identified and handled with care in order to achieve accurate results and prevent any potential damage during installation or maintenance of the engine.

Sometimes, it can be difficult to find the right part for a specific car. For example, if you have a small block Chevy, you might be looking for the exact bolts that attach the harmonic balancer and lower pulley together. In this case, you'll need bolts that are 3/8x24 and about 1" long. It's important to get the correct size because if they're too long or too short, they won't fit properly. You can usually find these bolts at any auto parts store or online retailer that specializes in car parts.
How do you torque a crank pulley?
If the bolt and washer are removed, they should always be replaced. Re-using them is not recommended as the torque may have been compromised in some way after being taken out. The new bolt and washer must be torqued to 130 lbs. ft., a measurement which can be attained with a torque wrench or other tool designed specifically for this purpose. Failure to replace the bolt and washer or achieve the required torque can result in damage to parts, potential injury, or even worse scenarios. It is therefore important that these instructions are followed carefully each time the bolt and washer need replacing.
How tight should a pulley be?
So, when it comes to tightening your alternator belt, the best way to do this is by using the "rule of thumb". This rule basically entails that you should keep tightening until the belt deflects about an inch when you push down on it with your thumb. Of course, for those not as familiar with automotive components and repair, this may seem a bit confusing. However, if done correctly and in accordance with proper procedure, you can be sure that your alternator belt will be tightened properly and will last for many years to come without any issues. It's important to remember that taking the time to ensure everything is tight enough is worth it in order to avoid any problems or malfunctions down the line.

While it is important to replace the bolt and washer each time it is removed, it is equally vital that the proper torque is applied when securing them in place. Every time this particular bolt and washer are secured into place, they must be torqued to 130 lbs. ft., as any more or less than this could cause unnecessary strain on the connection, leading to potential damage down the line. Therefore, both replacing these components each time they are removed and ensuring that they are properly torqued should be done without fail for optimal performance and longevity of use.
What happens if you don't zero a torque wrench?
For those storing a torque wrench for an extended period of time, it is important to remember to wind it down to the minimum scale setting before putting away. Leaving a torque wrench fully loaded in storage can have detrimental effects on its accuracy and performance over time. The spring inside the wrench has been compressed when at maximum settings and if left in this state for too long, the spring may become set which weakens it significantly. As such, winding down the torque wrench before storing will help ensure that its accuracy remains intact even after prolonged periods of non-use.
Are LS crankshafts forged or cast?
If you're looking for a crankshaft upgrade for your LS engine, the aftermarket 4340 steel crankshafts are an excellent option. They come in a range of sizes and configurations to suit whatever application you need them for. The majority of LS engines feature nodular iron crankshafts; however, there are exceptions like the supercharged LSA and LS9 engines as well as the 7.0L LS7 that all came with forged steel crankshafts. All these engines use a specific type of reluctor wheel attached to their crankshaft, which has either 24x or 58x tooth counts. With an aftermarket steel crank, you can be sure that it is designed specifically for your make and model engine so it will fit perfectly without any modifications required. It's also much stronger than factory parts, allowing you to take advantage of higher performance levels if desired without fear of damaging your engine components over time due to wear and tear from increased stress levels on the crank itself.
Should I grease crank bolts?
Sometimes, when dealing with bicycle maintenance, you need to pay attention to the smaller parts. Greasing the bolts is a necessity, as it helps keep them from rusting and becoming stuck in place. The inside of the crank arm should also be greased; this will help it stay lubricated and reduce friction when pedaling. Once all of these components have been properly lubricated, they can be put back together and your bike is ready to go!
How many bolts are on an LS crank?
So, if you are wanting to get the most out of your performance engine, it is important to know which generation engine you have in order to select the right components. The series LS1,2,3,6 and 7 engines all share a common 6 bolt crank flange bolt pattern while the LSA, LSX (aftermarket) and new LT1 & LT4 engines feature an 8 bolt crank flange pattern. This can be very useful information when selecting components such as crankshafts, pulleys or flywheels that must match up with the engine's crank flange. Furthermore, some aftermarket accessories may require a certain type of crank flange meaning it is even more critical for you to determine if your vehicle has a 6 or 8 bolt crank flange before purchasing any related components.

What happens if you reuse a torque to yield bolt?
The use of torque-to-yield bolts should always be considered a one-time use only. During installation, these bolts are subjected to a significant amount of stress and strain, which weakens the structural integrity of the bolt itself. If reused, they will not have the same clamping strength as when they were first used. Furthermore, attempting to reuse them can lead to dangerous consequences; if overstressed or improperly secured, these bolts may break or become loose over time due to their weakened state. It is therefore essential that torque-to-yield bolts be replaced after each initial use in order to ensure safety and optimal performance.
What is the torque on the pulley?
Sometimes the forces that act on objects can be complex and difficult to calculate. In the case of a pulley, however, the net torque acting on it is relatively simple to determine. Consider a pulley with two edges, one at its left (TL) and another at its right (TR). The net torque on the object can be calculated by taking the difference between these tensions and multiplying it by the radius of the pulley (R). If TL is greater than TR, then positive torque will correspond to a counterclockwise direction. Conversely, if TR is greater than TL then positive torque will correspond to clockwise motion. This calculation allows us to quantify how much force an object like a pulley may experience in various situations.
What happens if you over torque a torque to yield bolt?
When installing a torque-to-yield bolt, it is important to remember that these bolts cannot and should not be reused. This is due to the stress which has been inflicted on them during their initial installation - this means that even if they are tightened up again with the same amount of torque, they will not hold the same clamping strength as before. Furthermore, attempting to reuse such a bolt could cause it to break or become loose over time, rendering it ineffective and possibly dangerous. Therefore, it is essential for anyone dealing with torque-to-yield bolts to ensure that only new ones are used in any application where strong clamping force is required.
How much torque should a crankshaft bolt have?
It is essential that the bolt and washer should never be re-used and must be replaced every time they are removed. This is a very important safety measure as it helps to ensure that the bolt and washer will remain secure, giving you peace of mind when performing any sort of operation or maintenance on your equipment. Furthermore, these bolts and washers must be torqued to 130 lbs. ft., otherwise their security may become compromised, leading to potentially dangerous consequences if not properly secured in place. Therefore, it is essential that you replace bolts and washers each time they are removed, as well as ensuring they are correctly torqued before using them again.
What are the torque specs for idler pulley?
So, when it comes to the timing belt idler torque specs, there is a wide range of values depending on the engine type. For instance, some engines require 33 ft lbs of torque for correct installation, while others demand as much as 50 ft lbs. Still other types of engines may only require 17 ft lbs of torque in order to be properly secured. It's important to know what specific engine you have so you can accurately determine the proper amount of torque needed when installing your new timing belt idler pulley.

The GM Harmonic Balancer Bolt must be securely fastened so that it can effectively perform its job, and should be inspected regularly as part of regular maintenance procedures to make sure that it remains in proper working condition.
How do you torque a harmonic balancer bolt?
It is important to remember the classic rule of thumb when tightening an alternator belt. To get it just right, you should tighten until the belt deflects about one inch when pressure is applied down on it. This can be done by placing your hand in the center of the belt and pressing firmly downwards. Once there is approximately one inch of deflection, you will know that it has been properly tightened. It may take a few tries before you get it just right, but following this simple rule of thumb can ensure that your alternator belt will stay secure for many years to come.
Do you need a torque wrench for cranks?
Sometimes even the most experienced mechanics can forget to tighten a fastener. As such, it is important that all fasteners are tightened to the torque specifications found in the owner's manual before any component is installed. For example, when installing bicycle cranks it is essential that they be properly secured because if not, they may become loose and damage the interface which could result in expensive repair costs or even replacement of parts. Taking care to ensure that all components are correctly tightened using these torque specifications will help to guarantee an efficient and safe ride for years down the line.
