Iirc that washer is 5 degrees which matches the channel,the flat washer is to stop the spring washer opening apart,which is what had happened to the previous attempts .Some proper tapered shims instead of a stack of washers would work a fair bit better in that taper flange I beam.
Throw the spring washer - its just another flat washer when tightened - and the crappy wire ones simply open - as you found already. You've defeated any theoretical ability of it to stop the bolt coming loose with the flat washer anyway. If you want it to stay done up against vibration, a nordlock washer under the bolt head without that additional flat washer, and another under the nut (no flat washer there either) - if its going into a nut plate or captive nut that can't rotate, just the nordlock under the head will do. The tapered washer you already have in there shouldn't be able to rotate once tight and defeat them.Iirc that washer is 5 degrees which matches the channel,the flat washer is to stop the spring washer opening apart,which is what had happened to the previous attempts .
Usually a suitable torx bit hammered in get them out.New shape transit custom hard return PAS pipe from rack to reservoir.
It’s an alu pipe into a steel housing with a steel clamp and they corrode and fracture. I got asked to removed the broken off bit from inside the port on the rack
Plan A was to remove from van and machine it out. As I was passing I thought I would look. Stud extractor to break the oxide bond and a slide hammer / self tapper to remove it. Easy enough and happy customer.
No during pic as I was busy thinking!!
Anyone with these, check your pipes as it’s common. Feed pipe is mild and that didn’t look too clever either!
