Step and step cover cylinders

Had to replace my step and step cover cylinders. I was told that they cannot be rebuilt. After looking at the old ones, I believe I can get them apart and possibly rebuild them. Has anyone else tried this? I'm one of these that thinks if someone else built it, I can rebuild it. Sometimes I'm wrong though.

They can be repaired with new seals and years ago one of our members Brad Slaughters posted how to do it so if you do a search it should come up

Larry,
The size of the cylinders that you mention could not be found at automation. 8 inch stroke is with 3/4 bore.

Maybe this will help.
This was my step cylinder.
If the step well cover actuator is made by Ingersall Rand these contacts should be able to help.

Here is the step cylinder overhaul info:

You can get the kit from:
Kelly Supply (Grand Island,NE.)
Salesman is Terry Falkena at
800-918-8939 ext 233.

The new p/n for my step cyl 1995 U320se) is
2418-1089-081DFF-B18AST
The kit p/n is Rk2418-10.

If you can't get the cyl apart (or don't want to do it)
Call Denise Marsh at Ingersall Rand at 419-633-6926.
I sent the actuator and o/h kit to her.
She ran it through the training dept. No charge and even paid the return shipping!

This is something I posted sometime ago.
It worked for me because I couldn't get the wire key out of the end of the cylinder.
Those contacts may have changed but hopefully the phone numbers will still get you to someone that can help.

SPEEDAIRE 1-1/16" Air Cylinder Bore Dia. with 8" Stroke Stainless Steel ,...

My shaft is all messed up on the actuators so I ordered 2 new ones.. pretty cheap .. compared..
Update... these are a bit smaller in diameter overall.. very close to original length but need to be a hair larger.. will work and the step feels strong as you step on it but for the FYI crowd it is a tad smaller

For the price I wont complain

The solenoid valves that control the step and step well cover have flow controls on the exhaust ports. The open/close speed can be adjusted, independently, by opening or closing those flow control valves. The flow controls look like small cylinders with vent holes on the circumference and a slotted screw and jamb nut on the end. The slotted screw is the adjustment: CCW is faster, CW is slower.
