NH275 main drive shaft bearings

Hey all. Quick one, is replacing the main drive shaft bearings on a 275 a big job? Mainly, do I need any special tools to get them out before I get home from work? I can borrow a fair amount luckily.
Haven’t had a good look but was reading a post from back in 2014 which a guy was having similar troubles. His were in the pickup reel bearings (part no 45882). I had the task of doing those last year, but there is still a squeal somewhere. Thought I had it by replacing those pickup bearings. Cam follower bearing are in good condition. Only ones I haven’t done now are the main drive shaft bearings (part no 574844). Clutch still slips sometimes leading me to think one of those are shot. Will have a better look when I’m home in a couple days but if they are hard to get to, maybe I’ll need some specialised gear I don’t keep at home. Cheers all.
