Seal replacement with slip-on tool

Click to expand...
That's the Bosco's group head not the LSM which is different. LSM has only one gasket and much easier servicing.
Who is Patrick? I have been watching that video on YouTube for 2 years and I was going to service my profitec pro 800 according to his instructions! Great video with so much info.
about the tool I got it from espresso parts already and it's really solid! pricy but worth it imho. I saw many people 3d printing it or making it on their own but I'm not that handy 😂 so I went with convenience and good quality which will last for a long time. I think it gives easier access and the way espressotime is showing isn't that hard tbh.

The link please. Please also list what are the other tools did you order for servicing / changing our Evo Leva.

I won't print. I will also order.

Not sure until I try. I thought the top access is more convenient.

As I understand it, this item will also work with some slight filing of the 4 tooth: https://www.amazon.com/dp/B087CKXLVD?psc=1&ref=ppx_yo2_dt_b_product_details. it is about £20-25 delivered in the UK, VAT included.

I have bought one, but as I'm on the 2nd batch for the EVO Leva, I'm not yet able to confirm it works (I did order it based on some post on HB... which also indicated how to file the tooth)

Curious if from the first batch is someone with more unimodal burrs (ssp 98mm HU, 64mm brew burr, or 64mm ssp multi-purpose burr) with the lever, and curious if they can get any good results?

The high pressure is bad with those burrs, in general.

Though @The Systemic Kidwas using with EK I believe which (?) Includes one of above...

I heard from a guy who owns alex leva that he prefers the conical to the Monolith flat paired with his machine. Then Thomas on the Kafatek forum told @danielpughand I that he loves his Monolith max paired with his alex leva and he has no issues at all (I'm guessing he has the SSP Low Uniformity burrs or maybe the mythos). I think they don't have any issues and it's a matter of preference.
I am on the second batch and my grinder is MAX with the SLM burrs and my friend (who is also on the 2nd batch) bought the lagom p100. Unfortunately, we can't do side by side comparisons cause we live in different cities but I think we will gather good info soon. I bought helor 106 to try conicals and it's amazing paired with the robot so I'll be trying that too.

Flat is not unimodal and has no problem with high pressure shots. Suriken have no problem with high pressure shots, n'or do SSP LU.

I am talking only about those 3 burrs mentioned above, rest are not unimodal, and have no problem at higher pressure.

There are facts and they are real that some people like the simplicity of conical grinder because they have a wider range to hit the shot and have no problem if you press with higher pressure.

Flat grinders on the other hand are more sensitive.

I think you got it the other way around with the SSP burrs. High uniformity produces more fines unlike the Low Uniformity that's why Titus is marketing the Low Uniformity in his grinder as the best for filter coffee. I could be wrong tho I'll take a second look at them.

Ek with what burrs? it behaves a bit different depending on burrs and carrier. Flavors are a bit rounder, more generic if the pressure is to high for those burrs.

Question for @The Systemic Kid..

Separately feedback on those burrs in e.g. p100. Leaning towards max with shuriken (assuming my organ sale goes well) but with mc4.

I very much looked at Titus as well and from looks would be happy, but requires second organ sale. However I believe its LU or remade older ek43 (from memory), or >HU for espresso<.

@MW11 I did not get it wrong.

The more uniform the output of a grinder is, the finer you can grind. The finer you can grind the more fines you have.

98mm HU/ 64mm brew burrs and 64mm multi-purpose burrs grind the finest/more uniform/highest extraction in short times.

Because of that ultra fine grind they dont like 8-15 bar shots, but more like 4-6 bar shots.

I already had all these burrs in my grinders, and tested them for long (3-24 months), all 3 of them.

Heard the same thing so I added a variable speed motor to my HG-1 that runs between 0-350rpm. Using both stock and SSP 0187c sets, that should keep me busy and my darling wife happy for a while. In fact, the infinite possibilities are daunting and may take a while with the boss involved.

Yep he had a hg-1 too. I think you will appreciate it more especially with the new machine 👍🏻

This above.

.There is so much guff, assumed knowledge that becomes law , that one person says to another , that somehow becomes indisputable truth about a machine and grinder. Buy something, enjoy it, log off the internet stop listening to people who tell you it isn't good enough or you need something better.

The depth of bed on these baskets is significantly higher than a 58mm for the same dose. Which, all things being equal, will mean grinding coarser for the same shot time. So on the 98mm HU you are not grinding as fine as on 58mm. How this affects fines / pour characteristics will be interesting to see. I think the basket shape is a major reason why these levers produced great shots and maybe shots at 11 bar will suit different burr sets than std baskets
