"So hopefully the rebuild of the ram was useful to someone down the road."You hit nail on the head there. I have identical ram with identical problem.

Thank you so much for this explanation. Having the part numbers and supplier makes all the difference. One question : the maintenance manual shows cleaner rings as 16x24x7.5 but you have quoted MSWS-16x24x4. Why?

Secondly, what to you mean, "It was a bit tricky getting seals to start in bore so I used tail stock of lathe to push it." I dont have a lathe do i need to find someone who has one?

thanks again.
