/diy/ - Do It Yourself

Hello /diy/,
I am trying to repair my electric chainsaw and I am having some trouble reaching the broken part.
The broken part is that sort of spring in the pic right under the bearing, it's broken. To be honest I've found very little information about that online, I guess it's some sort of protection along the transmission shaft, some kind of shock absorber or something.
I've found a pair of sites that seem to sell a matching part like eg
https://www.workingmotors.it/macchine-da-giardino-e-ricambi/motoseghe/molla-albero-trasmissione-per-elettrosega-ama-1800-w.html

but my main concern is first removing the broken one, and I'm not sure how to tackle it. I can't remove the bearing with the bearing puller because it can't grab under it since the spring is occupying that space. Right now I'm thinking of trying to cut the broken spring with a dremel then removing the bearing or cutting the bearing and replacing that one too. I'd like to save the bearing if possible but I'm not sure it's possible.
Has anyone any ideas on how it's supposed to be done?
Ah, the model of the chainsaw is McCulloch Powermac plus 1800
