The preparatory work,All kinds of tools
Just do it,Empty the old oil from the tank
And Exhaust oil from oil cooler
Vent the residual oil in the nose and pipe
Remove the oil separator line, open the oil separator, remove the oil separation core, replace the old empty filter core, and clean up the empty filter
Clean the oil through the inner wall
Reinstall all pipes and fittings
Rerun it
It worked even better now
Perfectly!
