I have a 04 U320 with a air driven entrance step. There are two air driven pistons MOD# (SMC US19836) that drives the step in and out. One has developed a leak. My question Dose SMC have a rebuild kit for these pistons and if so who is the retailer for them? Thank You Karl
Try Kelly Supply in Grand Island NE.

I bought a kit for around $35.00
If the pressure regulator is set low that will cause those step cylinders to leak.
Karl,
I sent you a personal message.
