Replace wood splitter hydraulic seals?

So I took the piston, rod and gland to a hydraulic shop about 25 miles away where they custom measure and order the seals instead of tracking down the model and relying on a manufacturer’s dated and often revised part list.

They gave me a bag of seals, a set screw, told me where seals go and sent me on my way.

I didn’t know that they would take the piston off the rod, but I understand why they did.

Problem is, when I put the piston back on, this is a close as I can get set screw to align.

Not sure if I need more muscle, special tools to turn it. Or drill and tap some new threads (which means back to the (a) shop, for me).

I should of asked them to give it back to me the way I gave it to them: assembled. Oh well.

Special too to turn it and more muscle is basically the answer. The special tool is basically a pin spanner wrench. Some of those glands are put on with 300-350 lb/ft of torque with red loctite.

Thanks. I’ve never knew that tool existed, but will track one down.
