24648A000 KIT
Field installation of these kits will require removal of
the fluid end to replace the existing retainer and seals.
On some fluid ends it may be necessary to hand grind
I.D. of fluid end to fit new kit. The same spring and
gasket is used to hold and seal the retainer.
The rod seal assembly contains two seals, and two oil
seals with lips facing the power end. The oil seal can
be replaced without taking the fluid end off by remov-
ing the piston and the cylinder liner to allow access to
oil seal housing. Unscrew two Allen screws and place
into the other two tapped holes. Gradually screw
them in to push the oil seal housing off the retainer.
After assembling new seals in the oil seal housing, an
assembly thimble should be used on the end of the
crosshead rod for sliding oil seal housing back into the
retainer. Check gasket and replace if damaged. The
thimble should be machined from high carbon steel
and polished on the exterior to reduce the possibility
of seal lip damage. Place two Allen screws into clear-
ance holes and tighten snug.
