Elcarajillo .I seem to recall a post with E61 component dimensions listed. Can anyone direct me to it please. The brew head on my Verona does not appear to be working as it should. I want to check the lengths of the valve stems (upper & lower) as I do wonder if the ‘common ’ pattern parts are correct.
DavecUK Elcarajillo I want to check the lengths of the valve stems (upper & lower) as I do wonder if the ‘common ’ pattern parts are correct. Often they differ, there is no “standard”….If possible always get group parts that are used by the group manufacturer….even then a given manufacturer may have changed things over the years..much less likely of course. What exactly, is happening with your Verona?
Elcarajillo The infusion valve does not seem to open sufficiently (pressure / pump reading 9 bar. Also the exhaust does not seem as efficient as before. The cam is as unmarked. I did wonder if I had mixed the valve stems when I last stripped / cleaned / changed seals. Eye sight not what it was!!! I wanted to check the valve stem lengths.
DavecUK If the componentry is fairly new, try and carefully unscrew the cam follower pins on the valves 1 turn, if that’s not enough try half a turn more. Careful though, as some manufacturers thinks it’s a jolly jape to threadlock them on and they can snap the threaded portion.
