Floor Guides
Floor guides wear out over time, so their replacement is necessary for the packer to continue
operating properly. Usually, replacement of floor guides is done at the same time when sliding shoes
are replaced.
When sliding shoes need to be replaced because of wear, chances are floor guides need replacement
too. To replace floor guides, apply the procedure detailed in the “Replacing Sliding Shoes” section on
page 131. This procedure includes steps to remove and replace floor guides.
Upper Wear Pads
When the packer moves vertically by more than 3⁄16” (checked with a pry bar), the upper wear pads
must be replaced.
