LUBE FITTINGS
Special self threading type lube fittings are used in the
spherical joint assemblies. If it is necessary to replace
a fitting a standard threaded type may be used. However,
replacement spherical joint assemblies are supplied less
the lube fitting. Therefore it will be necessary to install
a self threading type fitting into the untapped hole pro-
vided when replacing the entire assembly.
