Video Transcript for Performance Tool Carbon Fiber Digital Caliper Review

Today we'll be looking at the Performance Tool four inch carbon fiber digital caliper. Part number PTW80157. This allows you to read from 0 to 4 inches or 0 to 100 millimeters. It moves in 100ths of an inch or 1/10ths of a millimeter. It has a nice LED screen. You hit the on button and it's easy to read.

You can switch between millimeters and inches. Right now it's in inches and now it's in millimeters. Just by the touch of a button. We also have our zero capability so when we move it down our measurement tool, if we want to measure something and see the difference between another measurement, we can hit the zero button and it shows us the difference. This is a negative distance or a positive distance.

Take it back to zero and hit the zero button again so we can start back from zero inches or zero millimeters. This allows us to measure the outside diameter or the inside dimensions with the other side. Now we can show you in action. On our trailer here, we pulled off our seal. Usually it's stamped with the measurements on it, but this one has worn off over time. WE can use our tool to find the inner dimension of our race.

2.18 inches. If we need to figure out the outside diameter, that'll be 3.35 inches. Other measurements that we might need to know. Come to our shaft. We've got the bearings that sit on our shaft so we might need to know the diameter of our shaft.

We can come up, be 1.24 inches and that'll be for our inner or our outside bearing. If we need to figure out our other, the larger bearing, the inside bearing, we do the same thing. 1.74 inches. Now if we need to know the difference between the two, we come up we get the inside bearing, we hit our zero button, that zeros it out, and we can come to our outside bearing and we see there's almost a half inch difference between the two bearing sizes. Same works if you want to figure out the dimensions here for our race because that's where it sits. This is where our race sits. If I want to do difference in that. I'll take our meter, I'll measure the inside diameter of our race, I'll hit the zero button, and then I can come and measure the outside distance of our race and see if there's any difference at all. Which, there's not, but if there was it would show us. There would be a negative difference or if I measure something bigger, it would show us a positive difference. That's it for a look at the Performance Tool 4 inch carbon fiber digital caliper. Part number PTW80157.Speaker 2: You can find this and everything else right here at etrailer.com What's up man.

Average Customer Rating:  5.0 out of 5 stars   (13 Customer Reviews)


by:

I have not used it yet but what I want to use it for it will work just fine then I can order the right parts for my trailer weather is not good right now to use it



by:

Works as described



by:

It works great and it's just plain fun. I bought it to measure bearing buddies and spindles. It works for that but it also has been great for measuring the diameter of carbon fiber tubes I'm using to build a sailboat mast and spars.

It gives instant metric to inch conversions - just push the in/mm button and the measurement in the display converts.

I've used it at least a couple of hundred times and it's still on the original battery.

Pro tip: Close it all the way before you turn it on.



by:

I have always wanted a digital caliper now I have one. I have always relied on my older read out types since this is the one etrailer uses I will be able to take the same measurements they do . My local bearing supplier has priced themselves out of the market so I use etrailer !

A very nice useful tool. First one I got had a malfunction and the company sent me another one right away

  • Locating Correct Replacement Bearings for 1996 EZ Loader Boat Trailer
    The VINs for the EZ Loader Boat Trailers usually start either with 1ZE or 1L8. I was unable to obtain any information from EZ Loader based on the number you provided in your question. The most accurate method for determining the replacement bearings you need for the trailer is to simply pull the hubs and check for the bearing numbers. These numbers should be stamped right inside the bearings themselves. If you are unable to read the numbers, you can also take a few measurements along...

Usually it is a metal cap that is just lightly hammered into place. Use a screwdriver to pry off the cap. Clean the grease off and measure the opening with a dial caliper...

  • Is a Small Difference in Wheel Pilot Hole and Hub on Hub Centric Axle Okay
    With hub-centric hubs like those on your trailer, it is important that the center pilot hole of a wheel is the same exact size as the hub bore. The hubs will center the wheels using the hub bore and the pilot hole of the wheel, so ideally this measurement should to be identical or it could potentially cause issues. Obviously, the difference between the 2.55 inch wheel pilot hole and your 2.5 inch hub is extremely small, but this tiny variance can still cause the hub to basically be secured...

    When measuring an axle to determine the weight capacity you'll want to measure along the actual axle tube. Anywhere between the spring seats will work fine.
