How to Use an Angle Gauge

| 00:00 | - In this module we're going to have a look at how to correctly use a torque angle gauge. |
| 00:04 | And while the modern crop of digital torque wrenches may have a torque angle function built in to them, it's still worthwhile having an understanding of how to correctly use the torque angle gauge. |
| 00:16 | So I've got a torque angle gauge here in front of me. |
| 00:19 | It's a relatively simple device. |
| 00:20 | What we can do is connect the socket that we want to use to the underside. |
| 00:25 | We can connect our torque wrench to the top of the torque angle gauge. |
| 00:29 | And then we obviously have a dial, as you can see here, which shows the angle. |
| 00:33 | We can rotate the dial to zero, thus once we've got it installed on the part that we're torquing. |
| 00:41 | And we also have an adjustable stop here. |
| 00:44 | Now the adjustable stop, we can use to locate against a part in the engine block or componentry that's not going to move. |
| 00:52 | And this will stop the torque angle gauge from rotating. |
| 00:56 | Let's have a look at how to utilise the torque angle gauge. |
| 01:01 | For our example, we've already torqued the main bolt here on our Toyota 2JZ block to the recommended torque setting. |
| 01:08 | And the next stage is to add an additional 90 degrees of torque. |
| 01:13 | Now while it's not essential, I always find it's a good idea to use a paint pen or a twink pen to mark the head of the bolts after you've done your first stage of torque. |
| 01:25 | Now all I do here is put a line on the head of the bolt. |
| 01:29 | And this just lets you reference later on to ensure that each of the bolts has been rotated. |
| 01:35 | So what we want to do here is make sure when we're marking the heads of the bolts, all of the lines that we put on the heads of the bolts are in the same direction. |
| 01:43 | So I'm just going to do that now. |
| 01:45 | Now we can take our torque angle gauge. |
| 01:47 | And I'm just going to fit the 14 millimetre multi hex socket to the underside of it. |
| 01:52 | And I'm going to locate this on the bolt that we're wanting to do up. |
| 01:57 | Now that sits quite nicely and you can see that I've got my stop located against one of the cheeks of the crank shaft. |
| 02:05 | We can now fit our torque wrench to the top of the torque angle gauge. |
| 02:11 | And what we want to do is get the torque wrench to a point where we're just applying a little bit of pressure. |
| 02:17 | And now we can make sure that our torque angle gauge is correctly zeroed. |
| 02:23 | So this requires us to manipulate the torque angle gauge around against our stop. |
| 02:29 | Now I've got the torque angle gauge aligned on zero and I'm ready to start applying some torque using the torque wrench. |
| 02:36 | And I'm going to be rotating here through 90 degrees. |
| 02:40 | Now I find that it's always a good idea to support the torque angle gauge with your other hand. |
| 02:47 | And this is just going to help prevent the torque angle gauge from rotating as we're applying torque with our torque wrench. |
| 02:54 | So let's go through that process now. |
| 02:56 | Okay so we have our zero marker correctly aligned and now we're just going to smoothly rotate the torque wrench through 90 degrees. |
| 03:05 | I'm supporting the torque angle gauge, as you can see here, with my thumb and finger just to ensure that it isn't going to rotate. |
| 03:12 | And while we are tightening this, we want to also make sure that the torque angle gauge doesn't move. |
| 03:20 | It's coming up on 90 degrees now. |
| 03:22 | I'm just going to smoothly and slowly come up to 90 and then stop. |
| 03:25 | And that's our torque angle complete. |
| 03:28 | Once we have completed the task of tightening all of the bolts, we can make sure that our paint mark on the head of the bolts aligns for every bolt. |
| 03:36 | While the torque angle gauge is a simple piece of equipment, it still does take a little bit of knowledge to understand how to use it accurately. |
