My slide motor is what operates my slide and it is not hydraulic. I called Lippert who owns the company that now makes the slide motor and they don't keep track of serial numbers nor is there a name on the motor. I would first ensure there is not some issue that is causing the slide to not retract/extend as it should physically and this is likely best done by an RV tech and then look into replacing the motor. On my unit, it would not be very hard. A Keystone dealer is probably the best place to get the right parts. Posted a pic of my slide motor... hope that helps as I can't figure out brand based on talks with Lippert tech support. Didn't go to Keystone but they likely would have been more help.
