What is the specification for torque?
Remembering that torque is the turning effort or force applied to the fastener to preload it, or place it in tension, and is normally expressed in inch-pounds (in.lb) or foot-pounds (ft.lb). A one pound weight or force applied to a lever arm one foot long exerts one foot-pound or twelve inch-pounds of torque.
What are the torque specs for a camshaft?
I attached all the camshaft torque specs for you below. The spec is in inch pounds and nm. 89 inch pounds is the spec you need. helpful? Let me know if you need more of these.
How does cam timing and Cam separation affect the engine?
The following tables illustrate how variations in lobe separation angle and cam timing will effect the behavior of the engine in which the camshaft is installed.
How are crankshaft degrees expressed in Camshaft specs?
This is defined as the number of degrees of crankshaft rotation that each valve that spends off the seat. All camshaft specs are expressed in degrees of crankshaft rotation. Crankshaft degrees are used because that’s the easiest way to measure these points on the actual engine.
How to read a cam card to understand Camshaft specs?
In this case: 108 + 116 = 224 degrees / 2 = 112 degrees. This brings up an interesting point that will also help when selecting a camshaft. Note in the lower right hand corner of the cam card that Summit Racing specs this cam as +4 Advance.
What are torque specs?
- Main and Rod Bearing Caps. Install the main bearing caps before installing the connecting rod caps.
- it is important to tighten all of the cylinder head bolts in small increments at a time until
- Exhaust and Intake Manifold Bolts.
- Other Components.
What are the torque specifications for a metric bolt?
Metric Bolt Torque. If the bolt diameter is 5 mm, thread series is Coarse, ISO 898-1 Property Class is 8.8, then. Torque for Ecoguard Bolt is 4.0 Nm, Lubricated is 4.6 Nm and dry is 6.2 Nm.
What are the torque requirements for bolts?
The required bolt clamping force for a joint is 20000 lbs. The torque required for a 3/4″ dry steel bolt to achieve this tension can be calculated as. T dry = (0.2) (20000 lb) (0.75 in) = 3000 (in lb)
What is an engine cam?
Cam engine A cam engine is a reciprocating engine where, instead of the conventional crankshaft, the pistons deliver their force to a cam that is then caused to rotate.
What is a torque setting?
Working on your car means you have to torque parts up when you fit them. Using correct torque levels is very important. Bolts will be tensioned when torquing up. Always use a torque wrench when installing parts on your car!
Where can I find the latest torque specs?

How many torquing passes in a criss-cross torque sequence?
Torque bolts and nuts in a “CRISS-CROSS” sequence using a minimum of three torquing passes and the maximum bolt stress as defined. PASS 1 Torque Sequence: Torque to a maximum of 30% of the final torque value in accordance with the torque sequence.
How to determine the torque of a socket?
A whole lot of engineering work must be done before a socket ever hits a bolt head. Engineers must determine the type and number of fasteners needed to secure the joint. They need to consider platings, coatings, lubricants and thread-lockers. They need to think about how the fastener will be installed.
Which is the correct torque sequence for a flange bolt?
Flange Bolt Torque Sequence. PASS 2: Torque to a maximum of 60% of the final torque value. PASS 3: Torque to the final torque value (100%). After the three basic torque passes are completed, repeat torquing the nuts at least once using the final torque in a “CRISS-CROSS” manner until no further rotation of the nut is observed. For easy handling,…
