Changed a few leaking pipes from block to arm.dipper arm and boom go from normal to slow and pump sounds as if it’s under pressure . It’s mostly slow but does go back to normal as well. Appreciate any help

I've seen new hoses made up and the crimp machine not been set up right or wrong arrangement of fittings and it reduces the bore of the fitting once crimped and creates a restriction in the pipe. We had a situation with 1/4" fittings on our crimper where it squeezed so much it actually blocked the hose and no flow at all through it.

Yea I never checked the ends of them .don’t think it’s the case here as it jumps between normal and slow . Good man
