On thursday i finally got this
crane to my yard.
1st look showd me that many of
hydraulic hoses were almost worn out. Rubber has worn off and metal fabrics are shown (some even slightly rusted). But, before starting to replace all hoses I'd like to test crane and see if valves and cylinders are working.
I've cleaned the bottom of
valve, took all these covers off, cleaned it and oiled it. Now everything seems to work smoothly.
Can i test it without this one cap? I assume i can, because these caps dont have any sealing and are very thin metal and only attached with 2 screws. Surely wont hold main line pressure.
There are one pantent build on this valve, because one of top
cover bolts are broken. Need to drill it off.
It has been used a lot, and worn out in center bearings, as you can see it has been fixed home, non-professionally.
.
Last, but not least. Last part of crane has got water in somehow, then it has freezed and made crane structure to bend and crack. Weirdly, there is no water holes left on any part ot this crane. Maybe its made to kept inside and one of the past owners has forgotten this outside too long.
PS. Congratz of hockey win.
