To determine which seal is used with a particular bearing, you need to know the outside diameter of the race used with that bearing. The LM11949 uses a LM11910 race with an outside diameter of 1.781 inches. Unfortunately most manufacturers of trailers like your EZ Load do not keep the complete list of parts based on VIN. The best way for us to ensure we get you the correct bearings are to pull your hubs and look at the bearing numbers printed on the face of the bearing. The next best way is to have you measure your spindle where the bearings sit Look at the stamping on the shield of your existing skate bearing. Most will be stamped with 608. This means you have 8mm. If stamped with 627, you have a 7mm bearing. You can also tell by the size of the wheel nut. A 9/32" nut will indicate a 7mm bearing. A 5/16" nut will indicate a 8mm bearing. Skip to main content.

The seal's outer diameter needs to be fairly close to this hub bore dimension. You'll need a precision caliper to measure the hub bore to the nearest thousandth - to three decimal places such as 1.234. The 10-19 seal has an outer diameter of 2.565-inches. A local machine shop polished the crank for me (one of the many things they did), and they gave me these measurements saying they were "about this size": Rods: 1.7706 - 1.7713” (44.973 - 44.991 mm) Main: 2.3611 - 2.3618” (59.972 - 59.990 mm) Wanting some more exact numbers, I got a micrometer and went through the crank. Nov 12, 2014 · Hello, been a while since I've posted on here. Was just wondering, short of pulling the backing plate off and measuring, if anyone would know if my rear end has a small or big axle bearing. I'm getting ready to order a rear disc conversion, and need to know. Rear end is a 28 spline that came out of a 71-73 Cougar. Thanks for your time. Lucas. Oct 4, 2017 · The vise is all you need to do the entire driveshaft U/Joints too. Mark the orientation of the yokes and the spline clocking too. Slide off the front yoke and open up vice to fit driveshaft through but where the jaws hit the bearing. Then with a mallet knock on the spline end to get the carrier bearing to slide off. Bearings/wheels come in 7mm or 8mm. 8mm is BY FAR the most common size. Some vintage skates, as well as specific high-end plates for artistic/derby skates will be a 7mm axle. This is a minority, so if you're buying Moxis/most Riedell/Sure Grip/any other out-of-the-box skate, chances are 99.9% that you're getting an 8mm axle. Jul 28, 2023 · The ABEC rating system goes from 1 to 9, with higher ratings indicating bearings with more precise tolerances and greater rotational accuracy. The higher the number, the better quality bearing you will have. Bearings rated 7-9 are considered “precision” bearings, while those placed 3-5 are “standard” bearings. slVT8F.
