chip61 664 #1 Posted October 30, 2020 I think I've seen this question before but I can't find it. Is there anyone that can rebuild the welded hydraulic lift cylinders?? The one on my C160 is leaking pretty bad now. Thanks 1 Share this post Link to post Share on other sites

daveoman1966 3,829 #5 Posted October 30, 2020 (edited) The cylinder your have #6618 is notorious for leaking at the end Internal O-ring seal. Here is a method to stop that leak and doesn't require cut and re-weld. Cylinder 6618…Leak Repair. There is an INTERNAL 0-RING (3) that wears out and that’s why these leak. To repair, in effect, an EXTERNAL O-RING can be secured over-top of the worn out internal O-ring…and that’s what this procedure does. I don’t have a pic of my finished product, but I’m also not gonna tear my tractor apart to show the repaired cylinder. One could cut it open at the weld, replace that internal seal, then re-weld it, but there is a short-cut that I’ve used for years. 1) Remove the Threaded Clevis (1) from the ram Shaft (2) 2) Locate a thin washer (6) with OD same as the end of Cylinder (5) at face (4) 3) Washer (6) ID to be slightly bigger than shaft (2)…not tight. 4) Locate an O-RING (3) to just fit over the shaft (2)… 5) Place washer (6) onto face (4) of Cylinder (5) 6) Using a punch, mark washer (6) with 3 drill holes EQUALLY spaced at 120 deg. 7) Drill 3 holes approx. 1/8 dia thru the Washer (6) 8) Reset Washer (6) onto face (4) of Cylinder (5) and mark TAP HOLES into face (4) 9) Driil holes (3/4" deep) and tap threads into the end Cylinder (5) 10) Make slight detent flair in washer (6) ID….make one side of it concave (to pinch O-ring) 11) Slide O-ring (3) onto shaft (2), then Washer (6) onto the O-ring 12) Draw 3 flat-head screws to secure washer (6) into tapped holes of face (4) 13) O-ring will seal off drips. 14) Replace threaded clevis (1) Edited October 30, 2020 by daveoman1966 4 Share this post Link to post Share on other sites
