How To Remove Needle Roller Bearings?

- Jul 14, 2020-

First, oil is heated to about 100 degrees Celsius and poured over the INA - Germany needle bearings before being extracted. This pulls them out of the thermally expanding bearing ring into the oil-free space between the bearings. 


This makes the work stable and reliable without damaging the machine, the bearings, or the shielding of the machines in the room. After the press press press on the INA - Germany needle bearings until they are pressed to a thickness of about 0.5 mm. 


Note that the press pressure point should be near the medium shaft and should not be biased. Pressing the bearings requires considerable dismantling force to pull the outer race out of its ankles. 

The most important precaution you need to take is not to remove the axle nuts with an impact wrench as it may damage the needle bearings and the CV joint in your vehicle. The rattling of the impact wrenches is also not good for limiting the slip in the differential.

Although it is not as strong as an engine, the articulation angle can seriously damage sensitive surfaces if the suspension is stuck at full height. 


Special tools are required to remove mechanical and industrial parts such as bearings, especially when installed on rotating machine shafts. These are called bearing pullers and are designed for a specific type of application. They are designed to be harder than the part they are working on, and there are a number of different types of bear pull tools that can be used in different parts of the vehicle. 


The pullers are manually or manually driven or driven by hydraulic cylinders to reduce the cost of physical labor. There is a chance that you will find a bearing pull on the steering wheel, steering column, and/or in the linkages. 


When replacing the exhaust, you must use a new gasket and ensure that the bolts are cleaned and coated with copper grease. I'm not saying you shouldn't use pressure washers, they're just a tool that should be used properly. The water inlet is caused by pressure - washing hoses are used very close to the storage and water finds its way into the storage. When pressurized water passes through the seal, place the narrowest bearing at the end of the hose. PS1.81 Wemoto is a very good price for a high-quality hose with a wide range of hose sizes. 


For the process to work on the bike, you need to read Haynes "manual, but it's important not to try to hammer the needle bearings. If you clear the camps out of the way, you destroy them, so you should not remove them if it is not necessary anyway. Pull the thick wall of needle bearings out of the crankshaft of a Chevy diesel '94. 

Put the sliding hammer back on, heat the bearings with a torch, let them cool, and heat them up again with the torch until they are hot enough. 


Many years ago, when I worked at Tool & Die, one of my tasks was always to drill and rub a really big hole around the dowel pin. There is a trick I use to circumvent these stubborn bearings on the outer ring: attach the pipe flange to the bearing, apply a weld and remove the breakage. If you are blind with dowels, you need to drill the properly-sized holes in a way with a dowel pin or trickle, but it works. 


I welded a few really small notebooks to try it out and it worked amazingly well, but I must admit I only used it once when I had nothing to lose. To relieve the thin needle bearing, a few small zaps with a Mig can squeeze it a little. When I tested the feeling of turn, the race came right back to me when the needle rollers on the outer ring broke. 


This method is simple and straightforward, but it easily damages the needle bearings. When they are at the end of the shaft, the bearings are surrounded by smaller bearings that can be removed by tapping them with a hammer. This method can be padded by pressing both ends of the shaft and removing the shaft ends, by tapping with the hand or hammer, and works excellently. 


When using this method, care should be taken to ensure that the spacers are positioned correctly. The focus should be on the correct distance between needle bearing and spacer and not the other way around. 


The lower part of the bearing is padded and can be removed by tapping with a hand hammer. This method is simple and simple, but it is easy to damage the bearings, so be sure not to overload them by pressing the end of the shaft. When the bearing is at the end of the shaft, palpate with the smaller bearing.
