I have a hydraulic cylinder (a tilt cylinder from a 12k forklift) that
is leaking. We took it apart and found that the rod is pitted on the
bottom and that probably tore up the seals.

So, my question is, what is the most economical option here, is there
perhaps a CNC based company that custom makes such things?Any other ideas?

Thanks

Get dimensions and look at the likes of Surplus Center in Lincoln.
Plenty of new surplus cylinders there.

Or there are "bone yards" for salvage/spare parts...here Abilene Machine
is close for ag equipment; there have to be at least a couple in a large
metro area like you're in/near that deal w/ industrial equipment same way.

You can buy chrome plated rod and have someone duplicate your rod, or
do it yourself. And there are services that will strip, recondition,
and replate your rod. No recommendation, bad or good, for these
places; they're just examples from a google search.

There are several small shops around here that rebuild hydraulics.
They don't advertise and I only found them by asking around. One which
I'd never noticed was on the way home from work. He had a sign out
front so people could find him, but no indication of what the business
was in his barn.

Another is my source of round steel cutoffs for making tools.

If you can't find a suitable replacement, could you not have your one
hard chromed and reground?

Heyn Iggy,

Why not just place a "stop ring" sleeve on the piston that covers the
pitted area? That will stop it travelling to the point where the
pitted part rides on and damages the seals. It will limit the maximum
lift, but an easy job.

Take care.

Repair it, Ig. Try www.baileynet.com. They sell replacement
_everything_, including rods, seals, the whole schlemeil. As long as the
cylinder bore is not pitted, anything else can be replaced more
inexpensively than the whole cylinder. If you can't find it on the
online pages, give them a call.

A former co-worker used to work for a company that repaired and rebuilt
hydraulics for mining equipment. He told me about some place around here
that would re-chrome cylinder rods and grind them to size for around $100
for the size he was getting priced. I figure it might be difficult to buy
the materials and make one much cheaper than that.

Anyway, you may be able to find someone in that area to fix you up for less
money than having something special made.

That same co-worker was one that I was making cylinder rods for, but smaller
than fork lift cylinders. The largest threads I cut for a cylinder rod were
1-1/2 - 7 IIRC. My cnc lathe could cut the ends for smaller cylinders
(3/4-16 TPI on 1" rod) in about 3 minutes per end including the manual tool
change from turning tool to threading tool.

MSC and Grainger sell Thompson chrome plated steel rods in various
diameters and lengths. The most economical thing for me would be to
get the rod from MSC as there is a store close to me and so no
shipping cost. I assume the end are threaded and that is something
you can do yourself.

Actually for me it would probably be cheaper to get some stainless
steel rod from the scrap yard if I can find the right diameter.
Probably not as good as chrome plated steel, but close enough.
