Oil to thick in wood splitter

[Jhenderson]

J , if bypass your referring to a system pressure relief valve , they are installed within the static pressure side of the system for a over pressure situation to protect valve. & cylinder o-rings and cyl.seal components . This rel.valve dumps back to the oil reservoir in such over pressure instances . Also a conventional spin on oil filter is normal on these splitters & micronsized to the oil viscosity and flow requirements of the pump . Often within the oil tank for protection although external mounting is often also used provide a cooling effect and easier servicing .

No. The filter head has a bypass in case the filter is plugged. It only works on pressure. It won’t bypass on suction. Your conventional spin on filter is not designed for suction. Just return pressure. Look at any splitter ( or other hydraulic equipment) you’re using for reference and take note of the filter location.

Napa 1551 is a 10 micron filter.

Can put a coarse strainer from the hydraulic tank to the pump. The 10 -30 micron filter should be on the line back to the tank.
If the oil tank is clean and the return line 10 micron filter is piped into the tank - then all oil is filtered that goes back to the tank. Inlet filter is not required since the hydraulic oil will not contain particles large enough to be captured by the coarser mesh strainer.

Also a fouled or improper sized cartridge filter could inplode on the intake or suction side lol.

All filters are only installed on the return line to reservior on these units . I have seen more than one cartridge oil filter implode when improperly placed on the suction line. Only large orifice strainer or screens are installed on suction or intake lines . In more expensive commercial / industrial applications a direct acting system relief valve to reservoir is installed just downstream of the hyd. pump as a primary over pressure safe guard . Oil filter relief or bypass is a secondary safeguard that is activated when the specified differential pressure ( delta p) from inlet to discharge operating pressure has been met to maintain optimal system flow requirements .
