To keep or to scrap, advice needed

Zachary Hoyt · Oct 1, 2011

I have two hydraulic cylinders that I have ended up with. One is a 3.5x8 John Deere branded with a bent ram that leaks oil out the breather cap. The other one is a 3x8 I picked up at an auction for $5 and it is seized, I tried hooking it up and it would not budge. Third item is a Farmall H crankshaft that I pulled out of an engine, I was told it has been ground .020 over, although I haven't checked that yet, and one of the rod journals is scarred from a spun bearing. I am somewhat tempted to scrap all of these things, but I don't want to throw them away if they are still good for anything. Any advice will be much appreciated.

Someone will want that crank,even if its damaged.The cylinders can be saved,too.Isave my old cylinders-spare parts make a good one from 2 or 3...

the cylinders could be rebuilt but im not sure what to do with the crank. if you have no use for any of it try and sell it first and that could basicallly make your desicin if nobody wants them.

The first cylinder with the bent ram will always leak at the seal. Thw second cylinder can most likely be taking apart, freed up, cleaned and reassembled. If you have a three part dye penetrent, you should check where each web meets the journal for cracks, if it is solid, the journal where the bearing was wiped can be corrected with a fine stone and a slow gentle hand.

You can buy good working cylinders for 50 to 75 bucks and the seal kit to rebuild one cost that.Scrap them.

Scrap them unless you have alot of space on a shelf somewhere.They could sit there for a decade or more.Remember these are not rare parts.

If that John Deere cylinder is 3.5" x 8" then it should have the depth stop with 2 rods on each side with a pin that you move to a different hole to change adjustment. If so it is what is called an "A" cylinder made for a Model A tractor and is a low pressure (1,250#) max cylinder and if the housing is not cracked then it is definatly worth saving as even if would not work someone with a A tractor might just want it to hand on the tractor at shows. Also someone may have a cylinder with good internals but hooked it to a high pressure system and cracked the housing and that they would want it for parts to rebuild what they have. The newer green, black or yellow cylinders would be either 3" or 4" but not 3.5" and they would not have the value of that "A" cylinder.

There's no way you can "overgrind" a crankshaft.

Think ya mean .020" under don't ya? :>)

If the leak is minimal, and he is willing to accept it, then he may get some service out of it.

I saw a pretty cool mail box that had a crankshaft as the vertical post

I caught that also. If that crank is already 0.020" under, and has deep scars in it once again, the only way it can be saved would be to have it built back up, and then ground back down to standard size. Only way that would be cost effective is if a tractor puller wanted to build a stroker motor and had some deep pockets.

That's right. That's what I get for typing in the evening when I can't think straight.

Crankshaft bearings used to be available in .030 size. If you can still find them the crank could maybe just be ground and still be usable.

Don't know about the cylinders but you should just scrap the crank, or it will end up like one of mine. It sat around for a few years always in the way. rod throws rusted up bad, Mains had the bearings wired to them they got stained from being damp. It ended up in my last scrap drive. Stan
