Not hard to do on the removal side. Take side shield down, remove chopper belt, unhook cylinder speed sensor undo bolts for inspection door and around the big stop sign. Go in through cage with a 3/4" bar and hook onto a spider and pull sideways until cylinder pops off drive shaft. I was able to do it myself fairly quickly. Once out a foot or so used loader/forklift/skidsteer, to hook a chain onto top bar and slowly pull out until about half way. Then used whatever system and chained cylinder to the loader or forks and slowly backed it out, a second set of eyes helps, you have a bit of clearance but not much. To reinstall reverse procedure, biggest issue is getting shaft and coupler splined, may need 2 people one in hopper one in engine bay for this. make sure to check the coupler for wear much easier to change now than later usually its the coupler and shaft is fine but not always.
good luck
