hyd cylindar

MSS3020 · Nov 18, 2009

The bucket hyd. cylindar has a flat place on the rod. The seals dont conform to it when it slides back and forth. Where I work they had a guy come in and repair a chromed cylinder that had smash spots on it and it needs to be perfectly round and smooth. So he drilled small 16th holes maybe 8th inch or so into the cyliner and used alum rod to fit in hole then cut off and pinged down to smash and hold alum in hole then gently filed till perfectly smooth. Can this same thing be done on a hyd cyl. and work. Smash is only 1" long by 1/8" wide. WHatcha think??

I"ve never hear of the aluminium rod deal. In fact I don"t see how that could work since there would be no seal between the repair and the rod. What I do know works is solder. This trick was shown to me by an old machinist/welder who had been doing it for years on big cylinders on cranes, crushers, shears, etc. What you do is make sure the scratch is cleaned just as you would anything else you would solder. He usually used a "regular" solder like 50/50 or whatever to fill the scratch. Once it was filled higher than the surrounding material you file and sand it to shape.
I"ve done it on several cylinders over the years and have always had good success with it.
