rattle gun off the front sprocket nut. Use the rattle gun to break free the rear sprocket nuts (loosen only) too while eveything is in place. You'll have to rotate the rear wheel to loosen all the nuts. Then cut the chain. Remove rear wheel, remove rear sprocket, install rear sprocket. Change out front sprocket. Reintall the wheel. Thread the chain on with the ends at bottom. Grease up two of the the o-rings and place them on the master clip post. Insert master clip from rear of chain. Grease up the other two o-rings and place them on the post. Put the plate on. Press it on. Rivet the post. Torque the front sprocket (132 nm?) by using the rear brake to hold the dern thing in place. Bend over the washer.
Riviting a chain on is easy. The hard part would be ensuring the tool is aligned properly. Set it up, torque it a little, back it off then check everything. Then finish pressing the plate on. Same goes for each rivet.
Wipe all that nasty grease off the chain and apply your favorite lube. Beer thirty about now eh?
