Mercedes Power Steering Pump Hardware Kit - FUCHS 515881

Can you explain what this kit is for, and the purpose of the gasket, clamp, and crush washer? Also, would it be a good idea to flush the power steering system on my 2014 C300 4MATIC at 75K miles? Steering feels fine, but I’ve heard it’s recommended to do a full flush, replace the reservoir, and change the power steering pulley around 100K miles because the reservoir has a non-serviceable internal filter that can clog over time. Would you recommend waiting until 100K to do everything at once, or should I change the fluid now and hope the filter isn’t clogged yet and keep replacing fluid every few years so it stays in good shape?

This kit is for flushing our the power steering fluid, the gaskets included are common leak points on these power steering systems so we include those at the pump and leading from the rack as well as the clamp for the suction hose on the pump. All meant to replace the old fluid, flush it out and add new fluid into the system with new gaskets. At your milage, I would not be worried about a this, but if there is a concern then the process is pretty straight forward. If you are planning a 100K service maybe best to wait and do all the additional maintenance and this at the same time.
