There is no end play measurement on this cone type bearing. It must be adjusted to what they call (setting pre-load). What you do is add shims until you feel no in/out movement of the shaft but a slight drag on the shaft when free spinning by hand.
It's like setting pre-load (adjusting front wheel bearings on a car/truck). Also, Don't forget to apply some antiseeze to the tine shaft for the next cleaning.
TroyBuilt does not offer a service manual on my dealer's site, Only owner's and parts manuals.
