By my research, Fram does not make a replacement for a 52114 hydraulic filter.
Cross reference hydro-gear filter number 52114
Replacement oil filter for Hydro-Gear Oil filter #52114 such as Fram , A C or other equivalent Filters .ThanksRedrider1934
The filter is on the suction side of the pump if you look at the hydraulic schematic, and the sump (case) of the 2800,3100 and 3400 series units is vented through the plastic expansion tanks. Thus the pressure on the filter is atmospheric (or a slightly less). To put it simply, the pump draws oil through the filter rather then pushes it so there is no pressure in the filter.
