Repair Jigsaw Bosch GST 135 BCE

In this video I repair a Bosch GST 135 BCE jigsaw with a broken rotor. For the replacement I bought the rotor from a Bosch GBH 2-20 rotary hammer, which I expected differs only in the shape of the impeller and the absence of the dust cover. But it turned out that the new rotor has the same number of teeth as the old one, but their diameter is 9 mm instead of 7 mm. But all these problems were successfully solved and the jigsaw worked. 00:00 Inspection 00:22 Dismantling 02:44 Faulty rotor 03:06 New rotor 03:19 Rotor modification 04:45 Assembly start 04:56 Bearing replacement 05:30 Guide roller repair 06:25 Assembly continued 11:07 Checking work
