I have a 936 moco that has stripped out the override clutch two times. I found a used shaft with joints and everything on ebay for about $200 but it stripped out after cutting about 100 acres. the part number at deere is AE56355 and costs about $950 . It comes as a joint with clutch in it. All I need is the insert clutch part but can't find a part number or anyway to order just that part. Has anyone had this trouble ? The dealer said the rubber mounts on the gear box needs replacement and it could have caused the splines to strip out but really no answer. I hope someone can help me find the insert I need to get back going without breaking the bank !
