Here are the steps to change the engine springs and the tools we used.
Needle Nose Pliers
Note: Not necessary to take off the lip seals unless you are changing them out as well.
Remove the engine assembly from the lower half of the unit.
Remove the screws from the top of the engine assembly.
Remove the connecting rod from the bar/engine assembly. Just give it a slight twist and it will feel like it unlocks and then pulls out.
Remove the center locking bolt with a flat head screwdriver.
Remove the plastic space bar
Remove the pump assembly to reveal the engine springs.
Remove the old springs. Use a flat blade screwdriver to pry up and off then replace it with the new springs. NOTE: Pay close attention to the spring orientation before removing it so you get it back in the same way.
