Subject: Pitted rod Hyd. cylinders?



Castroville, Texas

Is there a way to fix the pits caused by rust on hydraulic cylinder rods, other than replacing them?

Nothing any more cost effective that I know of.

Some cylinder repair shops re chrome them electrically. Saw one shop using liquid metal but that method probably worked long enough to get it out the door. Gifford

There was a posting on here about emery cloth and super glue fixing pitting.
What do you have to lose? All you need is a smooth surface so the seal isn't damaged.

good luck

Last time I priced that in Iowa, it was more than twice the price of a new cylinder from the implement maker.

See if you can find a machine shop that buys the chromed rod in bulk and makes new rods to your spec. Usually much less expensive than buying new rod from JD or CNH.

If it's something you don't use that often, why worry? Have had some really ugly looking cylinders get the job done.Had to have crowd cyl. on hoe repaired due to "weld scar = ME hitting 240 triplex. Welded up, ground down + recoat chrome $750. one spot + seal kit. Superglue/Jb weld is intriguing. Details?

These cylinders are used quite a bit.

I priced the rod today at my local hyd. shop. It was running (2x31) $100 plus, new seal kit plus all the labor comes out to $240 or so. New cylinder in the size I priced is $265.

Don't think that's worth screwing with. Either give it a new rod or buy the new cylinder if you think it's the same quality as having the old one repaired...

Dover, De
I would just go with the new on that one i believe, there is always those opp's and o-no's any human makes that could raise the price considerable... @ 25 buck's more i would like the new stuff. Do they have any warranty on the rebuild, or a warranty on the new?

The old rod makes a good bale spear if it is long enough.
I had a shop make a rod this fall for a hy-dump 6'x3"@$420 Cnd, but the hardware and seals are the originals, not o-rings.

you might consider that if you get the rod rebuilt you can specify heavy chrome that will last a lot longer than the junk they sell now.

Grandfield, Ok.
At one time there was a machine shop-hydraulic shop in Hulen(sp)Tx. Just about 15 miles NW of Lockhart that did this type of work. Economical and good, but not cheap but very fair.

I priced a new 3/4 inch rod not so long ago at hyd shop and it costs 100 dollars just to chuck it up in their lathe to make the threads on the end.

The emery paper/super glue approach works.
Smooth the shaft down with emery paper. If you've done it right, where the rust was will be little divets.
Now, wipe it clean. Wipe super glue over the entire shaft and yes it will run everywhere. LET IT CURE.
Take some more emery paper and smooth the cured super glue down. You will have a shaft that is smooth now and the seal will not get nicked.

That's usually what I run in to whenever we break a rod or other parts of cylinders. Usually new costs close enough to parts and repair that it seems to me to be a better choice to buy new.
