What are the head bolt torque specs?
If an engine produces 1,500 pounds of pressure and the cylinder head has 8 bolts, then each bolt must be tightened to 187 foot-pounds of torque to secure the cylinder head to the block.
What is the torque of cylinder head?
Tighten the cylinder head bolts in 2–3 steps in the proper sequence. The final torque specification is 59–64 ft. lbs. (80–86 Nm).
Where can I find torque specs?
Begin with the formula T = K x U x D x P, where T is the torque, K is a standard representing 1.33, U is the coefficient of friction, D is the diameter of the fasteners, and P is the necessary preload.
What is torque angle?
Put into its most simple terms, torque angle replaces a maximum torque value for a fastener with a specific amount of fastener rotation. After setting a low baseline torque, just to make sure the fastener is set, the fastener is rotated a precise amount to set the final position and clamp load.
Is there an app for torque specs?
With the help of diagnostic scanner hardware, the Torque Lite and Torque Pro apps for Android give you a peek into the inner workings of your car’s brain.
What is tightening angle?
With the torque- angle tightening method an initial tightening torque is specified, known as a snug torque (whose purpose is to pull – or ‘snug’ – the plates of the joint into metal to metal contact). An angle of turn is then specified for the bolt/nut to be rotated through.
What’s the torque range of a bolt head?
The tools come in pistol-grip, inline and angle-head versions, and the series covers a torque range of 0.3 to 400 newton-meters. Of course, even the most accurate tools are only as good as the specifications they’re designed to maintain. A whole lot of engineering work must be done before a socket ever hits a bolt head.
Where can I find the latest torque specs?
Find the most up-to-date torque spec listings in electronic format. FelPro-Only.com is your convenient source for advanced sealing information. It’s the place to learn and share “tricks of the trade,” find proper diagnosis and installation instructions, and enjoy easy access to parts reference.
What should the torque be on a torque table?
Torque specifications are shown either as an exact figure, or a specific range. Follow any special instructions or multi-step directions carefully to assure correct final torque. There may be different specifications for different size bolts, bolts in different positions, tightening bolts in several stages, or a cold engine vs. a warm engine.
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.
