Well I drained out the EP90 from the swivel joints on my Series 3 and replaced it with one shot liquid grease.
This might surprise you but the EP90 was leaking from the swivel joints prior to this change.
My question is this. The capacity of the swivel joints is one pint. The one shot comes in a pack with capacity 0.6 pint. Is it OK to run these joints with 60% filling of lubricant?
