How should the alternator body damage be solved?
In the use of the phenomenon of damage to the body, how to solve it? The following alternator series introduces you to three common solutions for damage to the body.
Frost cracking is the most common damage to winter alternators. Cracks in the body can only be repaired by cold welding in areas where they are not stressed. First, the crack holes are stopped at both ends of the crack, then several nails are placed along the crack, and then several pieces are fixed perpendicular to the crack direction, and the low carbon steel electrode is welded along the crack and the patch. Be careful to tap the weld with a small hammer while welding, and then use flame to correct it.
The alternator cylinder head bolt hole is slippery or damaged. This situation is caused by excessive force or cylinders when tightening the cylinder head nut. If it is a single wire slippery wire, it can be changed again, and a cylinder head bolt matched with the wire hole can be processed. If the wire hole is broken or a plurality of wire holes are slipped, it cannot be repaired. You can first ream the hole with a wire tap, then plug it with aluminum wire, or plug it with spot welding.
Alternator bearing hole wear. This situation must be repaired immediately. When the bearing hole wears lightly, it can be repaired by increasing the bearing outer circle method. The steel wire is symmetrically placed at a small point by oxygen welding on the outer ring of the bearing, and then it can be used by pressing it into the bearing hole. Another method is to use a 2 mm thick iron plate to make a large flat pad with a 50 mm inner hole, and make three wire holes on the flat pad and the body, and fix it with a flat head screw. When the bearing hole is severely worn, the original hole insert can be enlarged, and three small wire holes are formed in the joint between the bushing and the body, and fixed by screws.
