Position the new packing over the shaft and slide into the bracket.

Install the packing gland and the screws. Take care when tightening up the
packing gland screws so as not to cause undue pressure in the stuffing box.
Pull up firmly on the packing gland screws, back off to finger tight and lock the
screws in place with the lock wire.
Aluminum packing is the standard in models 1AC through 6AC.Following is a table of packing

2 5/8" 59/64"

Changing Rotation
Model AC pumps in sizes 1 through 6 are bi-directional and will work equally well in
either direction of rotation with no modification.
If outfitted with an internal relief valve (model ACV), these pumps become rotational.
Rotation cannot be changed in the field unless the cover/valve assembly is replaced.
To change the location of the suction port on pumps supplied with Tuthill's unique
automatic reversing feature (model RAC):
• Remove the cover screws.
• Rotate the cover 180° so that the boss on the cover points to the new suction (inlet)
port.
• Align the mounting holes and reinstall the cover screws.
Model C1G
Lubrication
Model C1G pumps are provided with a grease cup or grease gun fitting at the outer
bearing which also lubricates the packing. A good grade of medium cup grease, such
as Fiske Bros. Lubriplate #930 AAA, should be used. Apply until visible at the outer end
of the packing gland. If the pump is overheating, it may be due to lack of lubricant. Add
lubricant as needed or at least every 60 days or 500 hours of operation.
