Damage in the form of freezing crack. This is a winter diesel engine injury. Cracks in the engine body can only be found in the stress-free areas of cold welding. First, plug the crack at both ends of the crack, and then along the crack planting nails perpendicular to the direction of the crack of the debris, firmly welding along the crack, with a low carbon steel electrode. When welding, please use hammer to gently weld, after welding, please use flame to correct.
205 Bearing hole wear upper and lower balance shaft ends. This situation is immediate. If the bearing hole is slightly worn, it can be expanded by 205. The wire is symmetrically welded to the small spot on the bearing outer ring, corrected with a file, and then pressed into the bearing hole. Another method is to use 2mm thick iron plate to make a large plate with an inner hole of 50mm, make 3 wire holes in the plate and body, and fix them with flat head screws. When the bearing hole is seriously worn, the original hole can be inserted into the sleeve, and 3 plain holes can be drilled at the connection between the sleeve and the body, and fixed with screws.
Cylinder head bolt hole slip or damage. This is because too much force is applied when tightening the cylinder head nut or securing the cylinder. If it is a single wire hole sliding line, the wire can be replaced again and the cylinder head bolt matched with the wire hole can be processed. When the thread hole is broken and the multi-thread hole is sliding, the thread cannot be crossed. Trachoma. After opening the hole with a steel cone, seal it with aluminum wire or spot welding.
