No float in motor
 
Just got a brand new Trinity Monster Horsepower.Ive never run it. No float at all in the shaft; I mean none. What are the dangers of this? How can I correct it?

I have to say that the timing on it is 1° off. So pretty perfect in that regard.

Any help would be greatly appreciated.

Thanks in advance!

Minimal float is great. Nothing to correct. I'm assuming you paid big bucks for this thing so your getting your monies worth. ;)

usually the float is to give some room for thermal expansion and tolerance etc. I would suggest reshim the rotor to have a tiny bit of float

Aim for 0.5 to 1mm 'float'

I would say that is excessive, like how most T8's come! ;)

I would shoot for more like 0.1mm to 0.2mm (.004" to .008"). Just enough where you can feel it move, but not really see it so much.

But pull it apart first, some companies use small wave washers on the rotor shaft to take out the "play" but still allow for thermal expansion, etc.
In which case you are good to go!
