If I order new rod chromed can it be machined or does the rod need made then chromed ? Like I said its 1.75 dia needs threads for 3/4 inch nut on the piston end and roll pin on the other end to hold the eye for the pin to loader
 
I would think that if all you are going to do is turn down one end to 3/4 inch and thread it , and drill a hole for a roll pin, it could be done on a piece of chromed rod. The rod needs to be chrome only where it rides on the seals. I imagine that you have a source for the chrome rod, I know that Marmon Keystone used to sell it , cut it to the length you wish.
Good luck.
 
Yes I got them straight been loading hay with it . Works fine but I'd like to eventually get new rods
 
You can machine the chromed rod. A few years ago we bought a drop from Bailey's of I remember right and had a co-worker turn the end for me. Then I welded on the eye and drilled the cross hole for the loader pin. Worked great.

When I was working in the heavy mining equipment field we used a place called Cassidy's Machine Shop located in Macon, Georgia. They would straighten our hydraulic cylinder rods when they got bent slightly. If they were bent very bad, it was best to have them make a new one or get an OEM replacement if available. When the rods wore down in diameter enough, the wiper seals would let oil pass by,they would build up the chrome plating and then polish it back down to the correct size and it was always smooth so that the seals lasted well on it.

The rods are alloy steel, not mild steel, but they are tempered to be strong but not brittle. Grind the chrome from the spots that will be machined or drilled. Wear a respirator, or maintain clean air flow away from you and not into the building, because chrome is really toxic when heated (I just went through OSHA Chrome training) It will machine. Jim

Rods I've straightened worked so well so long I just forgot about ever replacing them.

No need to grind the chrome off before machining,. i've machined many a cyl rod to accept the piston and clevis. The chrome will peel right of on the first pass in the lathe.
For drilling one needs to grind a spot clean though.
 
This loader is probably 50 years old I think the cylinders it has are fine. I bent em the first time buy trying to Lift a 4x4x8 bale off a stack that was five high and I could quite get under it . rolled the bucket back and that's what bent it . I have looked at new cylinders and they are about 500 each but if then the original cylinders bend again that would still be cheaper than bending rods again so right now I'm just running it the way it is
 
Thanks I will be doing some more research and see who is the cheapest best quality I'm in Idaho so shopping might be the only thing
