Gotta learn how to "send a message"....sorry
What is the torque for the cylinder base nut/stud combination
Does anyone have advice on how to keep them tight.....anyone using Loctite? Which One?
Are any particular cylinders prone to leak at the base?
Thanks in advance

300-320 in/lb. is what I have read here. For some of the studs on the bottom cylinders you will have to remove the oil sump. Use locktabs to secure the nuts and torque-seal to be sure nothing moves. The nuts are 14mm=9/16" so you can use an ordinary cylinder base wrench (after a bit of grinding around the perimeter so it will fit in the tight space). Doug has the locktabs and sump gaskets.
