Vesuvius Pressure Profiling Machine - General Discussion

JahLaza The tube you circled is not where the valve seals. Clearly the vent valve is the wrong way up, but the red arrows show the valves viton seal and the seat is inside the tube, also shown with a red arrow. Check they are clean.

DavecUK yes, it was the wrong way up in the picture I took, it was the right way up anytime it’s been in place. Thanks for informing the identity of the valves.

my question was then on to the very bottom piece/tube/barrel, is there any internal part in that? If yes, can that be removed?

L’autre problem - what’s your thoughts on the straight 10 bar shot? It’s discharging water to the drip tray excessively for the entire shot. Many thanks in advance

Adrianmsmith ok, cool, that’s what I was trying to figure, because I think the part you circled red is causing my issue, and I was wondering how I might remove it. According to your diagram I should be able to remove it from the top of the barrel?

Adrianmsmith ok, tongue in cheek! Please appreciate my ignorance in the E61 arena!! I disassembled again, easily removed that piece which I see just sits there and couldn’t be contributing to my issue! I changed the spring for the spare one supplied by acs which is longer but has less tension, and that has resolved the issue although it’s a little too loose id say, so, the issue was the spring me thinks.Apologies to you and @DavecUK for all my questions on that 😌

JahLaza The spring you used was the longer preinfusion spring that is normally not used. They leave it in the bag in case you with to enable the preinfusion chamber for some reason.

JahLaza

It’s not a spare. Count the turns on the ones you have against my picture and ensure the correct springs are used. The “spare” is from the un-mod’d preinfusion chamber.

Thanks folks, I quickly realised that when I tried it out at temp/pressure. The other spring back in now. It does seem like the spring is the cause of the stiff lever action for venting though? I might look for a replacement… Any thoughts on the excessive water discharge issue?

JahLaza

If you disassemble again please post a picture of all of the parts laid out as you will reassemble them in the orientation you intend to reassemble.

Also confirm the cam is correct and you fitted the cam lever first then the top and bottom chambers.

I’m still thinking assembly issue, sorry as it really can’t be wrong if it’s clean and moly on all springs and surfaces for assembly.

Adrianmsmith ok will do tomorrow morning thanks again

Adrianmsmith Hi, I disassembled again, here’s some pics, orientation as I disassembled and reassembled. molycote everywhere, all along spindle, all around cam, all around valves where they meet anything else, put back together again, cam first, top barrel, bottom barrel, lever, and it’s still stiff. The only time it hasn’t been stiff is when I changed that spring!

JahLaza Where exactly are you putting this and where did it come from?

DavecUK Hi Dave, that sits in the bottom barrel, as per my previous post to @Adrianmsmith just now, I had thought that was causing an issue due to my lack of knowledge but it obviously wasn’t, so, that went back in as it had come out, sitting down snug into the bottom barrel. I had never removed that before yesterday, so it’s not causing any issue

DavecUK Photo from when I had mine. The “top hat” sits upside down as it were - under the spring.

Also note the orientation of this piece, compared to yours.

Did you have the machine from new?
