White Backhoe Cylinder Repair

I bought a White 2-62 loader and backhoe a while back and am finally getting time to work on it. So far, I only replaced a hose on the backhoe for $48. The cylinder for the bucket is leaking a steady stream of oil out of the top of the cylinder from the tube that carries oil to the bottom end of the cylinder. The tube appears to have a bend in it, PO must have hit something with it. The book says there is an o-ring and washer on each end plus a spring on the top end. I'm guessing you have to push tube against spring to get it out of the bottom end to replace the O-rings. Any ideas on getting the tube to move against the spring? Vise grips and a hammer come to mind, any better suggestions? Can a small bend it the tube cause it to leak around the o-ring? Can you buy new steel tube and make a new one if necessary? Any help or guidance appreciated. Chris

Remove the hose from the end and the spring, washer, and tube will all come out. The o-ring probably needs a split ring with it. A fix for those been lines was to use a piece of angle iron to protect it. Rather than tapping the ends on each side I slide the tube through heater hose to space it from the cylinder and put a large hose clamp around everything. Once the tube gets bent I've found I'm constantly changing 0-rings. Good luck.
 
Thanks, I'll give that a try after work tonite. Is there anything special about the O-rings or are they a common size? Can the split rings be used over? Thanks again, Chris
 
If you can't find the right o ring, go to your hydraulic shop. I have an assortment of 0 rings. The ones I don't have are the special O rings that go on the piston.

BYW, I leave my cylinders on hoe, only remove the end with the rod. Leave hoses on cylinder. Then I use a brake cylinder hone to clean up the cylinder where the o ring goes.
