My friend on the island of Kauai asked me to score this little hydraulic system plug kit for him as they are much cheaper on the mainland.. ($340.00 in the Islands) This blocks the service access hole for a spring and ball pressure valve. It is a common failure as when moisture accumulates in the hydraulic oil, this plug rusts out. I sent it to him in priority mail. The dealer in Lebanon Indiana has more than 100 of them in stock. NOTE: He scoured the web looking for a deal on this and he insisted that this Indiana dealer was the best price.. I'm not posting this to start a debate on where he could have gotten it cheaper. He asked me to score this for him, this is what we did. He has his backhoe fixed, end of story. From my perspective, this is the most ridiculous thing I have seen outside of the typical aerospace, military and medical spare parts horror stories. For that kind of money it should be made of titanium. AND then it would not be rusting out!
