Work performed on a 2005 38J Winnebago / Itasca that is using the HWH slide out room called StoreMore Flat Floor System or HWH StoreMore Level Floor. In this video you will learn how to remove and replace a HWH hydraulic cylinder that has started leaking from a blown oil seal. You will also learn how UNstick a slide wall that has racked or jammed sideways in the opening.
The part number of this hydraulic cylinder is RAP91371 or AP28614 or Winnebago part number 14594902704
Looks like these are not repairable and are on back order at the moment.
The hydraulic fittings and caps i used are size #4
