Many ways to check that, but do EVER check the threads(the aired portion) either with a thread gauge or against another like bolt on the portion that is engaged,therefore unchanged;you will be AMAZED when you see elongated threads,so junk but only a trained eye can see it just by looking,use another like bolt, its good threaded portion 0000003690 00000 n No. Also, Repeated loading in the plastic region will lead to unpredictable failure. e~.J^m[ygKy%j7KM+q/:.Qz9HnS Y3$4[8^kPEbD , JK!5nvb,[fs0*. Phone: (386) 423-5373. Too tight and you risk damaging the parts or the fastener itself. All points I believe to incorrect Tightening Procedure of the TTY Head bolts. Please make sure that you are posting in the form of a question. They are 11mmso Im in trouble. Even with changing stiffness, the relationship between torque and preload should remain the same. It is widely accepted that the majority of torque we put into a threaded fastener goes into overcoming friction in the assembly as only between 10 and 15 per cent goes into stretching the bolt to create tension. However torque angle specifications are becoming more and more prevalent, so understanding and knowing how to properly use them will be a valuable skill in your mental toolbox. Ultimately it is also more accurate, faster and will be able to record your results for the purpose of process monitoring, control and traceability. If we divide one by the TPI count, we get the amount of distance the bolt travels in one rotation (.0416 inch).

An answer less then 1 (e.g., .50) means that you need to If you need to be at 170 degrees final torque angle, mark your starting point, go less than a quarter turn twice, and then finish 10 degrees short of 180 from where you started. These are not angles which I could possibly guesstimate visually, not easily at least. All rights reserved. What this really points out is that using different lubricants will cause uncontrolled variables when attempting to create a stable load which is counter-productive. This value is then, changed to a value of force after subsequent calculations. 0000020575 00000 n I like how this is magnetic and can be attached to any of my ratchets or breaker bars. Must have tool for a heavy duty Diesel engine mechanic. Torque Angle Gauge Required when servicing many late model engines that use torque-to-yield fasteners. %PDF-1.4 % These fasteners are commonly torqued into place using a torque-angle method, but thats where the similarities end. Do I split the yield or do it in one shot? Set the torque wrench to the desired Nm, in this case 40Nm, tighten the bolt. Although though I have now rebuild over 347 small block Chevrolets, about 18 BBC and numerous Fords, and Chrysler engines in the last 50 years with only one failure caused by excessive RPM, I feel I am well versed in fastners and proper assembly procedures. I dont understand exactly what they mean by the word yield. Parts are just part of what we do. of financing, such as costs to file UCC financing statements, vary by state, and Obviously, we have two components we are attempting to join like a cylinder head to a block or a rod cap on a connecting rod. The engineers at Automotive Racing Products (ARP) have found that when using engine oil, the amount of friction changes as the fastener is torqued through several cycles. [] For a deeper dive on TTY bolts, check out Ask Away! This 2-stage process consists of a strain gauge being deformed which in turn converts this value in electric signals. What can be surprising, at rst sight, is how much stretch you can get from a typical bolt before it breaks.

Your recently viewed items and featured recommendations. I always replace them with new ARP or a standard engine bolt kit and not torque to yield bolts. TTY fasteners are designed to stretch to a certain yield point and not exceed this clamp load limit. Once they know that, they can run the numbers based on fastener size and material to determine the required bolt stretch to achieve that clamp load. Most of todays Diesel engines use the torque-plus method to tighten cylinder head and main bearing cap bolts. For all practical purposes, in the plastic region, stress remains constant (flat on this chart) with changes in strain. Please try again. 20% off orders over $120* + Free Ground Shipping** .

That would keep it permanently identified. SKU..114292. Error posting question. Because once the torque wrench is no longer required, you can use a breaker bar with a cheater pipe on the end, and you can pretty easily read the torque angle while tightening the bolt. Bosch EV Solutions However, this potentially more consistent clamp load comes at a price since TTY bolts are designed for one-time use only.

Tech Service: 1-800-533-6127 What does it mean to the automotive engineers who use the term? This unit measures the angles of the rotation after pre-torque in torque angle applications. Of course, if you change fasteners like converting to ARP bolts, then that torque angle spec cannot be used since the ARPs fasteners are made from a much stronger steel. A TTY fastener is actually employed because, once in its plastic region of deformation, its stiffness/Youngs modulus is much lower, raising the ratio of the compressed parts stiffness to the fastener stiffness. . is really needed to pre-load the bolt. I see the TTY issue as a possible cost cutting measure during manufacture. I needed to replace camshafts, and I knew that just one slip of the dial tool could ruin my day and make me wish I spent the money for this one in the first place.

Also on a cylinder head bolt, when the gasket relaxes over time, being in the plastic region of the fastener means that a slight reduction of its stretched length due to gasket relaxation means only a very small drop in clamping force compared to what the drop would be if it was in its elastic region. The 360 scale is marked in 2 increments and intervals of 10 and 30; easily zeroed . The Lisle 28100 torque angle meter is very convenient to use and to operate than the OTC4554 and KD3336 torque angle meters.

Bosch Fixed Ops Torque-to-yield (TTY) fasteners are a completely different style of fastener that have come into vogue with 21st Century engines. Lets get into the details on torqueing fasteners and the critical differences involved with each. Please try again. Even though there are dry and wet torque values to take into account the absence or presence of thread lubrication, as well as thread lubricants from companies like ARP designed specifically to combat the drawbacks of dry threads, or threads using 30w motor oil, the fact is there are a large number of variables that come into play with the external torque method. 0000008581 00000 n minimum return you should expect on your investment. Is there anyway to tell if TTY Bolts were used correctly ? Of course, the fastener heads are accessible. Interesting topic Mailbag: A Quick Guide to Torque-to-Yield Fasteners, Aww Nuts!

The very latest production processes and continuous control of the manufactured tools guarantee a high level of functional safety and longevity of the product., Great emphasis is placed on the service concept with KSTOOLS at all times. I invented this tool in my mind while tightening down the head, and drawing a pull angle on a piece of paper with protractor and pencil. Whats the difference between a torque-to-yield bolt and a torque-angle bolt? It is very accurate as long as you turn the ratchet or wrench at an appropriate speed. Torque combined with angle tightening methods can reduce the uncertainty in the tightening process by reducing the reliance on torque control alone. 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. The angles are used in conjunction with a torque angle gauge. Tightening process by reducing the reliance on torque control alone, is how much stretch can.
