What is the torque on rod bolts?
| Connecting Rod Bolt Specification | Steel Connecting Rods | |
|---|---|---|
| Part # | Dia. x U.H.Length | Torque |
| 90803 | 7/16″ x 1.940″ | 65 ft lbs |
| 90804 | 7/16″ x 2.320″ | 65 ft lbs |
| 90805 | 3/8″ x 1.920″ | 50 ft lbs |
Are connecting rod bolts torque to yield?
The connecting rod bolts are also TTY, but can be tightened up to three times for bearing checking. The balancer bolt is also a torque-to-yield fastener. The intake manifold, rocker arm, and rear cover bolts can be reused.
What is a torque to yield bolt?
What is a torque-to-yield bolt? It is a one-time-use fastener that is designed to stretch during the torquing process (installation). Because of this stretching, the integrity of the bolt is compromised. These bolts cannot and should not be reused due to the stress caused to the bolt during its first installation.
What is a connecting rod bolt?
Connecting rod bottom end bolts keep the two halves of the bottom end bearing together. These bolts are subjected to complex nature of stress as follows: Tensile Stress: Tightening of nuts stretches the bolts and subjects them to tensile stress, which helps keep the two components together under tension compression.
When tightening the connecting rod cap bolt what tool is used?
“Yes, you can quite reliably tighten rod bolts with a torque wrench, but this process assumes a few things. First, you must use the specified lubricant to give accurate torque readings. Second, you must use an accurate wrench; without insulting every home mechanic, not everyone has one.
Can you reuse LS rod bolts?
You can reuse the bolts. The stock rods are weak and usually break just above the large radius (no aftermarket (ARP) bolt will stop it)… If the rods are out, you should replace them with Compstar or equivalent/better; if you can afford it.
Can you reuse stock LS rod bolts?
Can I reuse TTY bolts?
You cannot SAFELY reuse a TTY bolt. The idea behind it, is that when tightened properly it will stretch to it’s intended torque. Once you unload the bolt, you cannot reuse it because it’s already stretched.
Are ARP rod bolts reusable?
Are ARP bolts and studs re-usable? Yes. As long as the fasteners have been installed and torqued correctly, and show no visible signs of damage, they can be re-used. If they show any signs of thread galling or corrosion, they should be replaced.
Can I torque my rod bolts to achieve the correct torque?
Torqueing your rod bolts without pre-determining the required torque to achieve the correct rod bolt stretch is not recommended. However if this is the only tightening method available to you, DO NOT EXCEED THE TORQUE AMOUNT INDICATED FOR YOUR BOLTS. NOTE: Your Crowerods are totally rebuildable.
What are the dimensions of the connecting rod bolt specification?
Connecting Rod Bolt Specification Connecting Rod Bolt Specification Connecting Rod Bolt Specification Titanium Connecting Rods Titanium Connecting Rods Part # Dia. x U.H.Length Tensile Lube Torque 90800 7/16″ x 2.000″ 90802 7/16″ x 1.700″ 90803 7/16″ x 1.940″
How to tighten connecting rod bolts?
There are a few ways to tighten connecting rod bolts, including the basic torque method, the stretch method, and the torque to yield method. Without a doubt, bolt stretch is the only truly accurate way to establish proper bolt preload.
How do I test my Crower connecting rods?
STEP 1: Your Crower connecting rods came with a connecting rod specification tag. Check the tag to find the rod bolt part number used to fasten your connecting rods. Rod bolt length listed here is the measurement from under the head to the end. STEP 2: Use the chart below to determine the recommended lubricant, rod bolt stretch and torque amounts.
