Connecting Rod Bolt Products

Why does a connecting rod bolt get damaged? One probable cause is when you over-stretch your rod bolt when you're fastening it to your connecting rod. there's nothing wrong in securely tightening your rod bolt, but if you force it too much, it can wear out. And without this component, your entire rotating assembly is at its most critical condition because nothing can hold all its parts together. So before this problem screws up your entire engine system, you must get a new replacement right away. When choosing the right connecting rod bolt, make sure to check the threads to see if they're tough enough to handle the tension especially when the crankshaft is in action. Crafted from premium-grade steel, your new connecting rod bolt is extremely strong and highly durable, making it a good investment for your car.

Connecting Rod Bolt: Shop the Right Way

The connecting rod bolts are vital components of your engine's rotating system, for these ensure that the connecting rod itself does not give way to too much tension load from the crankshaft. The bolts must be able to bend slightly when the crankshaft rotates, so they must be made from a high-strength material that can withstand such tremendous rotating strain. If not, continuous crankshaft rotation would break the bolts, the connecting rod caps would collapse, and you would experience what is called a thrown rod. In whatever way, you must preclude this disaster by choosing the best bolts for your connecting rod.

Shop Talk 101: The right bolt specifications

Connecting rod bolts are made from highly durable materials such as pure aluminum, stainless steel, steel, brass, nickel alloys, and silicone bronze. The last four mentioned are a bit prone to corrosion, but with regular oiling, this deterioration can be prevented. The first two are highly rust-resistant, and their life can be extended with regular oiling.

These bolts come in different looks. Some have rounded, flat, hexagonal, and embossed heads, but what you have to remember is that the right type of nut must pair with a specific bolt. Cap style and through-bolt-these are the two cap retention styles for the bolts of the connecting rod. You will not have a problem with this matter because auto parts stores provide the appropriate nut or cap when you purchase a bolt.

Another thing is that threaded bolts are said to be better than non-threaded ones, for the threading provides a good grip on the bolt slot wall. You can also find bolts with a wave design instead of the thread; this design is said to support and strengthen the rod. Buy bolts with rolled threads instead of cut threads because these are stronger.

Shop Talk 101: Other considerations

It is very important that your package includes a torque specifications document. Connecting rod bolts are installed with a very specific torque. Tightening the bolts to an incorrect torque will render these fasteners useless, thus leading to another replacement. Lastly, it can never be stressed much that you need to purchase a bolt specific to the make, model, and year of your vehicle, since every car operates at its best only when the matching components are installed.

A Quick How-To on Connecting Rod Bolt Replacement

A banging or knocking sound in the engine of your accelerating car entails a problem with the connecting rod. Changing a damaged rod is expensive because parts of the engine need to be disassembled for a rod replacement job. But perhaps the issue is just with the loose connecting rod bolts, which after thousands of miles have loosened the connection between the upper and lower half of the rod cap. Several miles of driving may also wear the bolts, but whichever the case, you still have to look forward to a 30-minute replacement job. Make sure to prepare the tools and follow the steps to prevent any hassle along the way.

Difficulty level: Moderate

Things you'll need:

  • New connecting rod bolt (with nut)
  • Torque wrench
  • Ratchet
  • Sockets
  • Oil pan sealant
  • Lubricant
  • Car lift

Step 1: Place the vehicle on the lift to gain complete access to the undercarriage. The height must be enough for you to get under the car and reach the parts you need to work on.

Step 2: Remove the undercarriage parts, then remove the oil pan. Make sure to keep the fasteners; label them or create a diagram so that you know the fastener-part matching. Be careful not to deform the gasket of the oil pan. Clean the gasket and the surfaces where it attaches to the oil pan.

Step 3: Rotate the engine to top-dead center position, wherein the number one piston sets at the very top of its compression stroke. In short, the piston must be farthest from the crankshaft. Reach this position to access the connecting rod and its bolts.

Step 4: Loosen the old bolts and remove them completely from the connecting rod. Oil the bearings and fit the top part into the rod, then fit the bottom part into the rod cap.

Step 5: While pushing the unsecured rod bearing and cap toward the piston, insert the bolts into the hole. Thread the bolts as far as then can go into the hole. Note: Lubricate the bolts prior to installation in order to prevent premature wearing.

Step 6: Place the bolt's nut with its flat face touching the bolt. Tighten the nut according to the recommended torque value for your car. Check your vehicle's manual for this.

Step 7: Clean the oil pan and apply the oil sealant to the oil pan. Let the sealant cure before reinstalling the pan. Secure the pan with the bolts, making sure that they are tightened to the correct torque. Replace the undercarriage parts.
