Hi in an attempt to locate a rattling noise coming from the front of my 575, have started by removing the sump cover and the oil pump. Whilst the oil pump shaft bearing looks OK at the first glance, am not sure the oil pump is. When holding the scavenging gears with my finger, and try to rotate the shaft there is quite some play before the scavenging gears engage (see attached video). Wonder if this normal or if this could be the source of the rattling noise? Many Tks Gianni
