Anyone out there familiar with model # W3RTN-42-29-150-4, Serial # 851-W3RTN-573? Got a call from a new customer- main hoist cyl is pouring out hyd oil. Has a standard upright w/ single hoist cyl mounted in the center of the uprights.

Question is- where is the packing located- at the top of the barrel or the bottom of the ram. I need to figure out if the entire cyl has to be removed or if I can just drop packing in from the top.

Any help is greatly appreciated- thanks in advance!
