Cyl rod polishing

[bones1]

I have found the source of my bucket cylinder leaks.There is significant scratches or scoring on the rod.Some will barely catch a fingernail.What is recommended to polish out the marks?Crocus cloth,powered wheels etc.I have heard to use a stone,what stone are they refering to?.

I think you'll have to replace the rod.

You can use Crocus cloth or 600 grit sand paper on any fine scratches but anything you can feel with a finger nail is way too deep to do anything with they will just leak and tear the seals out

when i posted up about my cylinder rod issues i THINK i got a suggestion that for small stuff (like yours) you could JB weld over the scrach then sand down flush with some high grit wet/dry (wet) paper.

thus filling the scratch.

IT was noted it was a temp fix, but could get you a year or more down the road.

It's odd that a fairly new machine should have significant rod damage. Do you have any idea what caused the damage? It usually takes years of dedicated hard use to damage a rod.

By the way, I agree that you can repair the damage by JB weld epoxy filling the scratches, then while it is still soft cutting any excess with a razor flush. Then wipe the remainder off with a rag wet with lacquer thinner. Last thing is to LIGHTLY sand with 600 grit 2" wide cloth. Don't be bashful with the wipe off step. It's much better to goof and clean it all out & refill than to sand off extra.

Remember, the Chrome plating is only a whispers thickness. You go thru the chrome and it will RUST.

You can wet sand with 600 gr, but anything scoring that is of anysignificance will cause problems. Give it a try worst case is it does not work and then replace.

I'f I were in financial dire straights.. I'd extend the rod out al the way and get the scratches away from the wipe, wrap a wet beach towell around the wipe end. then clean the scratches out with brake cleaner.. then build up with silver solder or brasing rod.. then contour down with a file, then hit with fine paper.

Not great.. but better than jb or other epoxy that can contaminate the hyd system.

Otherwise.. i'd get the rod replaced if i could afford it.

If you want it repaired correctly, the best place around our area (that I know of)

Hydraulics Unlimited Inc
193 W Hampton Ave, Capitol Heights, MD 20743
(301) 336-4436

I didn't have much luck with the "other guys" in Waldorf.

Now, there may be a good local shop in Amish country but, I'm not familiar with any. They do use alot of hydraulic stuff, though. Next time I'm near Ryceville, I'll have to ask around.

I have some buffing machines I use in car restoration, stainless,alum resto etc and rubber backed abrasive wheels and various grit compounds for polishing.Do you think I should try any of these?.Tlbuser, I'll use you suggestion if it comes down to it.Never thought to use JB weld or silver solder/brazing.I've got both loader cyls to do as well,all leaking pretty bad.I'll post some pics later of the rod and the packing if I can zoom in that close.

Like Chris said the best way to repair the existing rod is by silver solder/brazing it. If you do use JB Weld, make sure that you get the damaged area cleaned very well. I have seen JB Weld used on cylinders for many years and it has held up well, but like I said they have to be cleaned very good before the JB is applied.
