I've gave up repairing this one, Husqvarna K770

‪@Dany_FIX_DIY‬
part 2 video about working on this Husqvarna Power Cutter.
it all started as a restoration idea, soon I've discovered it wasn't going to happen.
I've so decided to just clean it well enough and just repair it.
but I've eventually gave up with it because of the time involved and other projects going on which have a priority.
I'm not excluding a day in the future it will come back and maybe succeed with repairing it.

Hi, thanks for sharing. Did you refit the shaft and bearings for the blade head ? I'm just in the process of doing the same project going through a k770

Hi, thanks for commenting, it's very important for me. I'd like to receive more comments from the viewers to interact and help each others with our projects and build a little community. Anyways yes I did refit the shaft and the bearings, I did off camera to not loose parts because my actual workshop is few square metres and I have to keep the bench always ready for new projects. I've ordered a new carburettor for this Husqvarna cause it's the cause of the malfunction which made me gave up. But because I bought parts for it I cannot leave it incomplete. And maybe next video we will see it running . What's going on with yours? I've had little bit of struggle with the installation of the intake assembly because of the lack of space , especially for fitting the return line from the carb to the primer bulb , despite I have thin fingers it has been a challenge .

Hi, I have problem with my spindle when mounting a cutting blade. When I tighten the blade onto the saw it doesn't rotate easily. I think it might be the bearings or maybe something else. The motor runs nicely no problems at that end. It's just the cutting head that needs some attention. Taking the saw apart was a good opportunity to give it a good clean if nothing else , it needed it !

@@nicholastighe8450 I think you might be surprised. The thing works just like that. I didn't know either, but on the cutting head beneath the pulley there's a brake assembly, which is probably what you are referring for not turning easily . It's mounted on the pulley with 4 machine screws and has 4 little spring loaded pads, those run onto a stamped steel bushing fastened to the alluminum cutting head . When the rpms reach enough speed , centrifugal force pull the pads away from the bushings , releasing the brake . You still might have a bad bearing but you can just remove the pulley and check if there's any excessive run-out or noise in the bearings.

Yeah I thought it might be the brake but checked that and it seems fine. I am going to try rebuilding the cutting head and give it a try with maybe some new bearings
