PTFE垫片卡在85052B校准套件的滑动负载怎么去除？

我有一个HP 85052B（3.5 mm，26.5 GHz）标准校准套件，带有911E（3-26.5 GHz）母滑动负载 - 看到我贴在这个帖子上的几张照片。
序列号为00538，部件号为00911-60020。
我相信在测量时使用的PTFE垫片会卡在负载中。
中心导体相当牢固地保持在中心位置，并且不能通过手指的一点侧向压力移动很多。
我已经尝试将滑块放在顶部，RF连接器向下，然后向下滑动滑块，希望气压可以将其移除。
但我无法做到。
我怀疑它需要拆开。
谁能告诉我如何将它分开？
我确信我可以尝试在不知道怎么做的情况下把它分开，但我很可能会毁了它。
毫无疑问，是德科技会为它提供服务，但它的成本会高于我买一台用过的 - 一个新的高达6984美元！
显然，我收到的任何信息都将由我自己承担风险 - 我不希望任何人承担责任，因为我会遵循您的建议并对其造成损害。

  I have an HP 85052B (3.5 mm, 26.5 GHz) standard calibration kit, with a 911E (3-26.5 GHz) female sliding load - see a few pictures I stuck on this post. The serial number is 00538 and part number of 00911-60020.

I believe the PTFE spacer used when gauging this is stuck in the load. The centre conductor is held fairly solidly in the centre, and can't be moved much by a bit of sideways pressure from a finger. I've tried putting the slide at the top, the RF connector down, and sliding the slider down, in the hope that the air pressure might remove it. But I've not been able to.

I suspect it needs to be taken apart. Can anyone tell me how to get this apart?  I'm sure I could try to get it apart without knowing how to do it, but the chances are I would just ruin it. No doubt Keysight would service it, but it would cost more than I could buy a used one for - a new one is a whopping $6984!!

Obviously any information I receive will be at my own risk - I'm not expecting anyone to take responsibility of I follow your advice and damage it.
