Hi All, I have now got the cutting assembly separated. Will try to post pictures. The bearings seem OK, but the thread for the grease nipple on one of the bearing housings is stripped. Much worse, the left hand (looking from front) bearing housing is cracked where it is held by the "cutter bearing housing pivot". This pivot unscrews with an Allen key, but I have not attempted to undo it, as turning it will almost certainly complete the fracture in the housing. A new cutter bearing housing would be the best answer but I have no idea whether this would be available - part number 651268. The pivot also looks a bit moth-eaten - part number 651284. I also feel that a new bottom blade should be fitted - part number 652746. Could one of you please tell me whether these parts can be found, and how I should go about it. Hopefully, I attach illustrative photos. MacCullum
