Air Compressor Motor Bearing Replacement?

hey guys i recently bought a PilotAir Compressor from a classified and upon inspection it worked great than i got it home and on the second use it started giving me grief i originally thought it must have been the belt as the motor would keep spinning once near the shut off pressure but the belt slipped

so tonight i pulled the belt off and ran the motor there is the usual whine noise using a mechanics stethoscope i than shut it off and rotated the motor by hand and seems the front bearing sounds sandy like it has sand in it, so im looking at replacing the motor bearings

is there anything i should keep an eye out for? i have never fiddled with a 240v electric motor like this, i know the capacitor can hold a charge am i able to snip one wire at a time (capacitor has 2 wires) without being electrocuted? the wire joiners are the crimp type so only way to remove them is to cut the wires

hopefully someone can help out with advice or have previously done this

compressor came from a fence building tradie im using for anything pneumatic related mostly for a new business i plan on taking from a hobby to professional and part of that is building shipping crates with a nail gun and drills for shipping my goods in
