A bearing might look like a small part of a big car’s tire but it surely owns a big responsibility on itself. The vehicle might not be able to drive even a few centimeters if the bearings do not hold its tires in place.
The bearings are used in many a type of vehicles or stationery moving heavy equipment and machinery etc. like diesel engines, earth movers, material handling equipment, compressors and much more. These are used to hold the tires of these machines and are therefore, pretty important irrespective of their size. It would be adequate to associate them with the idiom, ‘big things come in small packages’. We cannot negate them and if there is a need to replace them, as the tires are running too flat or may be the vehicle’s alignment seems wary, we must replace them immediately.
It is though not very easy to replace these bearings but it is also not that difficult a task that it cannot be done without expert help. It can very well be managed on a person’s own as we know that flat tires can be changed without mechanics as well.
Step by step process of changing the bearings from old to new is listed below.
Step 1: The vehicle or machine or equipment should be standing stable on the ground. If it is a car, it should not be in movable condition. Any movement during the change of bearing could lead to some damage the car. The car, therefore should be parked and in neutral gear with the power brakes on.
Step 2: We need to elevate the tire whose bearings need to be replaced. So, the other tires should be blocked using chocks first. Now, in order to elevate the tire, we need to put the jack and pull the tire up as we do to replace a flat tire. With the jack, in place and the chocks preventing the other tires from any kind of slippage, we are now ready to replace the bearings. Do not forget to loosen the lug nuts before you lift the tires.
Step 3:Now unscrew the lug nuts completely and remove the wheel. After the wheel is removed, slowly remove the brake caliper, the dust flap or cover if any, the cotter pin and the castle nut.Ensure to keep these parts safe with you as you would need to replace them after you change the bearings.
Step 4: It is the turn to remove the rotor now. It should be done carefully as it can be damaged. Use your palm to get it uplifted from its place and then remove it cautiously.
Step 5:Unscrew the hub bolts and the old hub: We need to remove the old hub which holds the bearings inside it. Since the bearings are clutched quite inside these hubs, you may use a wrench to clear all holds and then finally take off the bearings.
Step 6: Now is the time to replace the old bearings with the new set. Always ensure to use a lot of grease on the bearings. You can do that either using your hand or through a bearing packer for applying grease which comes as a ready tool.
Step 7: Now is the time to go reverse the order and replace all parts again.
You are done with the changing of old bearings now and your machine is ready to work!
