EuroJamb hqcctool00000000 Husqvarna Crankcase Assembly Tool as nos 250 400 430 500 ahrma To suit just about all Husqvarna applications from mid-seventies on, absolutely correct for any Swedish HQ originally fitted with Motoplat or SEM This tool takes out all the drama when reassembling the crankcases I used such a tool when I was in the business back in the eighties Screw the adaptor onto either end of the crankshaft, turn the 'meat grinder' and the cases pull together like magic The double-ended adapter is 14mm r/h thread for the drive side, 12mm l/h thread for the timing side
