Good Morning to all,
I was working with the backhoe on my D14 Industrial, when I noticed the main up/down boom had started leaking down very slow. No external leaks, just bypassing around the piston, I'm guessing. The backhoe is a Henry's Model Mark IV "Mfg For Allis Chalmers" with SN of IA682. The cylinder is 4'-0" long and 4" OD. The rod is 1 7/8" OD (2"?) with 1 1/2" pins. I can't measure the overall length of the travel of the rod, but with the hoe extended on level ground there is 17" of rod showing on the cylinder.
I rebuilt this machine almost from scratch, new 149 engine, repaired the Power Steering, replaced all the hydraulic hoses on the loader and backhoe. The absolute hardest piece was disassembling and rebuilding the rotary swing cylinder,,,,whew,, THAT was a job!!
In my neck of the woods, there is not a shop within a couple hundred miles that can rebuild this cylinder and it being so old,,is prolly wore out internally. I don't really want to remove it til I have a replacement located and preferably on site,,,,??
Is anybody here familar with this particular backhoe cylinder that can suggest a replacement that don't cost an arm and a leg?
Many THANKS for any suggestions.
