i put a new robinson racing spur gear on my savage and when trying to set the gear mesh i notice that it wobbles . what would be the cause of this im guessing that its slipper clutch hub or the slipper plate. any ideas on what it could be?

1 or 2 millimetres will not cause a problem

Worn out washed most likly take it off and check for damage by where the screw goes threw and check the washers for wear. and 1-2 mm will make a huge problem

^^^agreed. 1-2mm of wobble in a steel spur will create massive amounts of heat. Trust me, I know from experience. For me, the fix was as easy as turning the spur 180 degrees. Basically flip the spur on the pin. Straightened that baby right out.
