Is there any harm in leaving this in place??

[nvrrdunn1]

I installed a crankshaft rotation adaptor (one of those 3 bolt plates with the 1/2" ratchet drive in the center..see pix.) I didnt want to rely on turning the center bolt to rotate the engine. Had issue finding TDC with a new motor/new dampener/pointer, which has been resolved (I HOPE). The engine is in the car and not a lot of room to work between the pulley and the radiator, and its a major pain in the waazoo to put this thing on and take it off and thought it might be handy to have it in place from now on, but......
My question is this: Once the center bolt holding the harmonic dampener is torqued to specs, is there any problem with leaving this adaptor bolted in place on the harmonic dampener?
