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.
