How much do you have ? 

 

Specs for XU10 is pretty wide :

0.07 is next to nothing in my book. Installed one Yesterday and could not find the feeler gauge. Managed to fit 3 pieces of paper to meassure the gap- which equals approx 0.2 - 0.3 mm. end float. Seems very tight though?

Not sure about the paper measurement ! 

Use feeler gauges or dial gauge of you have one , never guess while building engine .

 

If it really ends up too tight , check if the washers are installed correctly , if they are you can resurface them by hand if you don't need much to reach desired spec. .

600-800grt sanding paper taped down on something flat spray some WD40 and spin the washers in motion 8 and recheck the measurement while doing so , best with micrometer .
