Hello all. New member here. Was going to change the filters and oil on the hydros (ZT-3400). Jacked it up and it looks like the left side will not be any problem, however the right side I don't know if I can even get a wrench on the plug. It is an Allen plug. Even if I can get the plug out the fitting that comes in the kit would not thread in because of clearance issues. Anyone been through this problem? Thanks.

Take out the plug leave it out and fill the hydro through the expansion tank. It will hold about 2 quarts. You can then finish filling the hydros after you put the plug back in. You will see bubbles coming out of the hydros into the tank until full.

Been there I just pushed the hose that came with the kit down inside about and inch or so and pumped until full. Then topped off from tank
