In the case of the LS main cap bolt, with a preload of 15 ft.-lbs., the torque-angle for the inner bolt is 80 degrees. For the best experience please upgrade or visit the site on another browser. 0000011762 00000 n 0000015039 00000 n An electronic torque and angle wrench measures both applied torque and angular rotation. The amount of torque applied to the fastener is proportional to how much load we want to apply to the head gasket to ensure that it seals. Use Code: APRILOFFER. It is an interesting question if there is a different tightening sequence, which uses a torque value for the first three steps, and just one angle for the final step, which would give the same bolt loading tension, but thats probably not an experiment that Id be looking to perform. It shouldnt be too much work to mark off 170* total angle on the bolts and head, marking 10 degrees short of half a turn can be done with a protractor. First, it overcomes friction between the threads in the block and the bolt as well as friction between the cylinder head the underside of the bolt head. I used the paint marker trick when I replaced the cylinder head on my Caravan, but on that engine, the head bolt tightening sequence had only one step with an angle, and the angle was 90. Hence they are so good with aluminium heads especially. TOLEDO Torque Setting Angle Gauge - 1/2. There was a problem completing your request. Thanks Jeff for the information provided in this article. 99. I doubt the purpose for this as there is no expansion and contraction in driveshafts (not heat). 0000019064 00000 n It is very accurate as long as you turn the ratchet or wrench at an appropriate speed. 0000002955 00000 n Another variable that directly affects normal torque values is accuracy of the torque wrench. The use of a Torque Angle Gauge is necessary to achieve the correct torque for the cylinder head bolts, rod bolts and crankcase bolts. While that is still a highly effective method of determining clamp load, there can be some drawbacks and inconsistencies with the method. Also there are torque to yield bolts that can be used more than once.

Instructions from teng. Rates used to calculate payments, taxes, and costs Whats the difference between a torque-to-yield bolt and a torque-angle bolt? Please use a different way to share. So on the graph it states that torquing a bolt to its yield point will ensure the same camping force regardless of the thread friction. Even with changing stiffness, the relationship between torque and preload should remain the same. 0000019788 00000 n So the point of all this besides educating you on fasteners, is that any bolt can be tightened with a torque-angle specification, but that does not mean that it necessarily is a TTY bolt. Free In-Store or Curbside Pick Up. I can use it on anything from 1/4 drive to 1-inch drive breaker bars. Its easy to see how big problems could be created by a wrench that under-torques fasteners by perhaps 8 to 10 ft.-lbs. It also gives audible feedback when target angle is reached. Error posting question. I would contact ARP for help with this problem. Whats confusing is that TTY fasteners are very often tightened using the torque-angle method. Ive also heard that youre not .

This tends to stabilize the load for a head gasket, as an example, when the engine is both cold and then as it warms up especially it the engine is all aluminum where material growth is a concern. In Stock. Contact Supplier Request a quote . GB 119 1060 05, Interestingly though, a very slight change in friction can disrupt the torque vs load relationship so if you reduce friction by applying a lubricant, it will result in more tension for a given torque compared with the dry condition. 0000005252 00000 n I bought this to work on my 335i since I couldnt bring myself to use the dial type tool. The majority of them, on the other hand, may not meet the product's primary needs or application criteria. Products with electrical plugs are designed for use in the US. when the spec calls for 65 ft.-lbs. The amount of clamp load (how much the fastener squeezes the two objects its joining) is determined by the fasteners diameter, material, and how much the fastener is stretching. Your question might be answered by sellers, manufacturers, or customers who bought this product. is there a part which anchors somehow to the non-movable surface around whatever fastener is being tightened? Publishing? All you have to do is be able to accurately set the first-stage torque (which is usually relatively low, in order to be able to better withstand any variations in conditions) and then properly measure rotation from that point forward. The angle you reach for the first 2 steps isnt life or death critical, thats just so you stretch the bolts slowly and gradually. The number of degrees establishes the clamp load by ignoring the actual torque required to overcome friction. A professional would (or should) use a torque wrench with a gyroscope built into the head like Tester linked above. To put it simply, using only ft-lbs, most of the torque is used to overcome friction. All financing, rates, and This must-have tool can service late-model engines.
