Changing Hydraulic Filters

[1965tontruck]

I am going to change the hydraulic filters on my 5600A. When replacing the filters do I need to fill the new filters with hydraulic fluid before installing them on the machine.

Thanks for the help.

No need to pre-fill and better if you don't. The filters are all pressure fed from the pump, no suction filter so they will purge themselves with the pump flow when engine starts. Even new oil from the bottle can have some contamination in it, if you pour this in the center of the filter it goes straight to the hydraulic system without passing through the filter.
