Fixing oil leak from the oil cooler hose W123

Good morning, so here i am giving a rough overview of what i did to fix the leaking oil cooler hose on my W123 diesel.
Note: i put on a almost completely worn angle grinder cutting disc, so it was a small diameter/radius disc so less chance to accidentally cut anything else that was close.
Note: the clamps were 21mm to 23mm in size range.
note: cut the outer crimped clamp, that is okay, you have about 1 to 2mm thick hose before you get to the important barb underneath, don't cut too deep.
Note: you will likely have to cut each metal crimp twice to get the crimp off, use a large flat screwdriver to get the crimped piece off. ( they are sharp, be careful )
