I believe they are all right hand thread, but they will be on VERY tight. I remember something in my manual for my 731 saying to be very carefull when un-doing any nuts in that area as if the bolt or socket broke flying metal shards may damage your eyes. I am un-sure what tension they are done up to but i do know its pretty damn tight. I think it advised wearing goggles when tightning or un-doing these nuts. Please be carefull
