Smooth demolition bearing main skills and demolition precautions, such as knuckle shaft bearings mounted in the roots, is more difficult to split out, this time we should borrow dedicated puller tool, or a waste of effort is one thing, damage bearing unnecessary.
If the bearing is too tight is difficult to remove, you can use the following method.
Bearing disassembly: the three-jaw retractor hooked wheels at the edge of the screw top up against the steering the section shaft center hole and turn the screw can be easily removed before the bearing inner ring, pulled out together with the brake drum.
Disassembly of bearings: bearings installed in the root of the knuckle shaft, more difficult to split out, is not easy to operate, and can use a dedicated puller can easily split out. Two semi-circular cone inner circle, including pulling condom bearing puller, tighten the fastening bolts, and then pull the collars to pull the condom live, so that it can not be opened, and then rotating the handle so that the tip of the screw in the center of the knuckle end hole, continue clockwise handle, you can pull out the inner bearing.
Old leaf spring removal: from the use of oxygen in accordance with the tire nut center on the appropriate length of the old leaf spring cut cut two hole slightly larger than the diameter of the tire nut outwards, the concave surface of the leaf spring, knuckle front end screwed into the nut end first flush in order to protect the knuckle thread, fill in the appropriate thickness of the pad between the leaf spring and knuckle, at the same time tighten the two tire pressure on a leaf spring nut, take advantage of the elasticity of the leaf spring, may be not too tight the bearing pulling outward. If demolition is still no less bearing, hammer a few times in the middle of the leaf spring to produce vibration force, then tighten the nut.
Prior to demolition should clarify the relationship of bearings and related parts: careful observation of the relationship between the bearing position where related parts, analysis of the installation process and methods, and then work out the demolition methods and procedures.
The 2 without disassembly try not to split: separate bearings, the inner and outer rings are usually using the interference fit, to ensure that with the precision, the shortened the repairman period, can not be demolished try not demolition.
Using the scientific method of demolition:
(1) Remove the journal, the force on the inner ring, remove the bearings should force on the inner ring of the bearing seat.
(2) Remove the inner or outer ring of the bearing, the force should be balanced, even not skew case stuck.
(3) Remove the bearing, not easily broken objects percussion, pressure unloaded or a dedicated removal tool to remove individual cases is also available in brass or other soft metal liner percussion.
