Ogura PTO clutch

Scag Turf Tiger
Model STT61V-35BVAC-SS
Serial. E5400225

Any thing unusual I should look out for when replacing PTO clutch on above mower? Any special tools needed.
I am guessing that it might be really tight on shaft. Please advise.
Thank you,
Knots

Need a decent torque wrench for the bolt holding the clutch to the engine shaft and perhaps a strap wrench to keep the shaft from turning when you reinstall it.
