    Default Bradco 511 Swing Cylinder

    My 2007 511 BH has a leaking swing cylinder. Anyone have any experience with removing one? Or can it be rebuilt while installed on the backhoe?

    Well, I never continued this thread. I bought a swing cylinder rebuild kit and rebuilt the left cylinder. Fast Forward to September, 2015. My right swing cylinder started seeping. Instead of buying a kit, I took the seals and orings to my local hydraulic shop and bought replacements. Mahindra/Bradco kit was $80 something dollars. Hyd. shop price was $24. A big difference. This time I took photos, but forgot to take photos of the assembled rod before installing it. Total time was about 2.5 hours.Bradco 511 Swing Cylinder-9-5-15-steering-cylinderBradco 511 Swing Cylinder-9-5-15-steering-cylinderBradco 511 Swing Cylinder-9-5-15-steering-cylinderBradco 511 Swing Cylinder-9-5-15-steering-cylinderBradco 511 Swing Cylinder-9-5-15-steering-cylinder
    My gland nut wrench is hard to use, as your really need 3 hands.Bradco 511 Swing Cylinder-9-5-15-gland-nut So after I break the nut loose, I use large channel lock pliers to turn the nut on and off. Thus the roughed up paint.

    A few weeks before rebuilding the swing cylinder, I rebuilt the dipper stick cylinder. It was a lot easier to rebuild, as the larger bore made it easier to install the new poly pak seals inside the gland nut. I messed up the poly pak seal on the swing cylinder and almost got it in, when the inner o ring popped out. I took the gland nut to the hyd. shop and the owner straightened up what I messed up. Anyway, I forgot to take a few rebuild photos of the dipper stick cylinder rebuild also..........Bradco 511 Swing Cylinder-8-22-15-old-dipperBradco 511 Swing Cylinder-8-22-15-dipper-stickBradco 511 Swing Cylinder-8-22-15-dipper-stickBradco 511 Swing Cylinder-8-22-15-bad-dipper
    These seals and o rings cost $36. I also needed help installing the rebuild rod and gland nut assembly into the bore.

    Next cylinder will be the bucket curl. It always has a drip under it now. I will do it in a few weeks. Then I can stop putting a bucket under it when parked in the barn. The cylinder that is gonna be a chore is the boom cylinder. It also has drips on it's lower end. This cylinder is also all up inside the boom. I promise to do more picture taking when I tackle these rebuild.
