Coupling
Illustration 27
Coupling has normal wear, minor dents, scratches, nicks, etc.
Use again
after reconditioning by filing or sanding.
It is permissible to use couplings that have had the zinc-chromate coating removed by bead blasting or exposure to non-caustic chemicals. Such couplings should be painted after they are assembled onto hoses to prevent corrosion damage.
Illustration 28
Coupling has been repaired by welding.
Do not use again
Caterpillar does not recommend welding on hose couplings. Welding could cause localized stresses which can lead to reduced fatigue strength and performance life.
Illustration 29
Coupling has been exposed to fire.
Do not use again
