    I'm trying to remove a grubee GB & clutch from a new HS motor & tranfer it to a Honda. The clutch won't slide off the shaft (see picture). Does anyone know a good way to get it off. I've tried prising it out from both sides with screwdrivers but don't want to break it. It's brand new & never been used.
    I'd be grateful for any advice.

    mine was stuck too. i heated up the shaft, and the clutch but not the pin, and it came off easy. DO NOT LET IT GET TOO HOT you can ruin your clutch that way.

    Thanks a lot HoughMade I need that gear puller. Will search Australia cos postage from US is ferocious. BTW Eltertato, what did you heat the shaft with and how do you avoid heating the key if you can't get it out?
    Addendum: I tried a 3 jawed gear puller like HoughMade suggested and it was too big for the job. I got the clutch out a bit more but it's really stuck tight. Will buy a proper sized 3 jawed puller tool next week but meantime I'll knock the clutch back in and try and pull the key out with pliers. Just something I thought might work. hanks to both Hough & Eltertato for your help. I've also had big trouble with a HS\Hoot motor and am starting a new thread about that. I think I've been sold a lemon. My trusty HT supplier (ZBOX Australia) is new to 4-strokes and I think they've shipped him a load of Mark 1 gearboxes. Incidentally the shafts are the same diameter on both HS motors for the Hoot & the Grubee. The lengths look similar too but I'll measure them accurately when I get the clutches off. Isn't this MBc a great resource?
