Crankshaft repair issues
Thread Content
May I ask, in the case of piston compressors and high-pressure water guns, when crankshaft wear leads to excessive clearance that exceeds the allowable range, what is the general approach to dealing with this situation? Can it be chrome-plated by repairing it like a regular shaft? Should it be replaced directly or paired with a matching bearing shell?
1. The bearing bush can be thickened temporarily for use； 2. It is possible to consult the manufacturer before reducing the size of the crankshaft assembly ；
It’s best to replace it directly, as repairing it makes it difficult to ensure the accuracy of its center of rotation; if this leads to cylinder scoring, the consequences will be even worse
First, determine whether the crankshaft is worn. If it’s the bearing shells that are worn, they need to be replaced; if it’s the crankshaft itself that’s damaged, repair is rather complicated, and it’s usually best to have the manufacturer handle it.
Our factory has experienced crankshafts being damaged due to insufficient lubrication. It is usually sent back to the factory for repair. Lower the shaft vehicle and re-fit the metal bearing.
Thank you for all your suggestions. It seems I’ll have to get in touch with the manufacturer to see if it’s possible to repair it; if not, then I’ll have no choice but to replace it!
It mainly depends on what the problem is. It can be fixed. . Repair can also be carried out using laser cladding. . My phone number is 13406519300
Generally, appropriate bearing shells are selected based on the circumstances; after all, items like crankshafts are too expensive
