Hi,

Ok, to measure the drive-end clearance between rotors and end-plate:

Remove the outer casing, keeping only the drive-end endplate, with bearings and screws installed.

Keep the air-end vertically. So the screws press down. Now you can measure the clearance with a feeler gauge. (just push it between the screws and the endplate and see which one fits, to get the clearance.

(see photo below)

To measure the clearance at the non-drive end, put back the outer casing. Now you will see that the end of the screw is almost flush with the end of the outer casing.

Now measure this distance with a micrometer. When the end-plate is installed, this will be the clearance.
