Hello, I purchased this Vio 27-3 and it's had to so far have a whole track frame re-welded and completely rebuilt. (was in salt water in it's early life) That's fixed now. I have an issue with the blade currently which drops when the control handle is in the middle. The blade doesn't hold like it should. It will drop like it's losing pressure. I wondered if this was the cylinder but it's not. The Blade will stay up if the control handle is pulled all the way back, but it won't hold anywhere in the middle, it either drops to ground or stays all the way up, there is no middle positioning for the blade like there should be.
The blade cylinder has been confirmed good by technician. He believes it's the Spool Assembly, Blade section of the control valve. He's adjusted the spring etc with no change so he doesn't believe it's the cable or linkage. but the blade section of the control valve.
I called Yanmar for part 172457-74260, 172457-74270 or 172457-74300, and they stated no more parts exist. It seems silly to have to toss a perfectly good excavator because I cannot procure one part. Anyone know of a part that may work with this from a similar model Yanmar? Yanmar themselves cannot legally tell me they've stated. I found a part for a Yanmar Vio 20-3 which looks like it could work potentially. 172458-74750.
I would like to know if there are any other aftermarket replacements for this blade section, used parts for this section (in working condition), a similar part from another machine that would work, or any place I can find a new part. I need options, anything you can think of, even if it's expensive. I'm new to this kind of stuff and tried looking on the internet for these part numbers but have had no luck. Nobody I can find seems to sell them, but that may only mean I suck at searching.
Attached is the pic for my actual Vio 27-3 parts manual. Highlighted in Yellow are my part numbers, and the part I need a replacement for. Again, i'm looking for ANY solution, and don't really care about legalities, just need something that will work.
Thanks for your help.
