Ive been away out of the country so not everything is fresh in my mind but, yes Frank I did trouble to look at Mikes helpful post but only today was I able to go the workshop and look at the old cam and housing and start to understand it and even what journals etc are, now i understand a little more so posted what I knew. As you know I am not a mechanic or even a beginner, I was just trying to work this out. Have a nice day.
