Vesuvius operating cam goes back...

Spid3r00

Hi,

For some days ago I installed new preinfusion valve, drain valve and I saw that preinfusion spring (which was missing, but I think @DavecUK said that the spring should be removed?)

Anyways now operating cam don’t stay in place during pressure, please see the video:

Any ides?

Have you checked that the cam is installed in the correct orientation?

Spid3r00 @DavecUK has provided great info on this and recently shared this insightful pic on here on some other thread. This is taken from an article on his very useful website

Spid3r00 the Vesuvius doesn’t have the pre infusion spring by design (I.e. the first spring coming out of the group to the drain side is missing in the Vesuvius)

JahLaza Exactly like that but without preinfusion spring (in the middle), right?

JahLaza

Spid3r00 yes

Spid3r00 look at this video, have you re assembled the group like this?

JahLaza I did reassemble the whole group now and it seems solved the problem… I guess when you changes preinfusion cam you also need to reassemble cam lever to get all in the place.

Still same problem without the preinfusion spring, cam goes back, strange…
Even cam lever is new (apx one month old).
