May I ask what material or type of bolts should be used for the coupler bolts of gearboxes and mixers? Can ordinary bolts be used as a substitute?
It’s best to replace it as it is, since we don’t know what the spare parts you’re using look like. Mostly it’s pin bolts with spring washers; there are also nylon pins and star-shaped washers.
Don’t change them randomly; what if something goes wrong? It’s better to buy original spare parts
No, unless it is verified through design
If replaced, only alternatives of the same or higher grade can be used.
