Lamborghini Countach QV resto update Pt.5. There's an unexpected problem with the gearbox

[@richardjones38]

'Pull to release' clutches give a slightly higher clamping force (i.e torque capacity) for a given pedal effort relative to 'push to release' clutches, because they allow a slightly stronger diaphragm spring to fit in tho the pressure plate diameter. This comes at the expense of additional assembly complexity with the clutch release mechanism, hence them being worthwhile in some high powered applications, but not worthwhile in more normal applications.

[@russcooke5671]

Well said. Is it the same for Automatics. 👌👌

[@jerryc6497]

The Honda S2000 has a pull type clutch fyi

[@Macedonia270]

As an Engineer, I appreciate explanations like these, thank you very much Richard.

Craig gets my personal Oscar for Best Supporting Role in Harry's and Ian's videos. For me, his matter-of-fact descriptions of such intricate and demanding work are never less than enthralling. Those carpets are a revelation.

Without Iain Tyrrell and his uniquely talented team of specialists, work like this would take years. It's a privilege to see how it's done.

Craig is definitely a real asset to Tyrrell's Workshop - seems a quiet and unassuming chap, but really is a highly skilled craftsman whose restoration work is absolutely fantastic. I'd love to work there, even if just making the teas and coffees!! 👍🏻😉

[@MrDDawson]

I will say it again. Any day we get Harry and Ian in the same video is a great day indeed. I can't thank Harry enough for bringing Ian onto KZbin for us all.

I heard it was Olivier Namèche who convinced Iain to start the KZbin channel ?

Thank you for the update. To put my 10p in, I'd have the other side wheel bearing done while the car is with Ian. If that side is gone the other is not usually far behind.

[@frankchan5547]

One of the few mechanical tasks I was able to do on my Alfa. I found out SKF made all OEM bearings which were simply put into Alfa packaging with mark up added, and saved some money by buying direct. Probably the cheapest part of this process

Love the exhaust reverb as the Countach passed the truck. We have a tunnel my brother and I go through on our MV Agusta triples, and we always drop down to second a run close to the redline just to hear the exhaust noise…pure joy!

[@monkeybarmonkeyman]

I enjoy all the banter with the crisp closeups as I've been a gearhead for nigh on fifty plus years now. You look at that engine, the casting marks, just how it goes together... I think you can still see a bit of post-WWII construction going on there. High marks for that carpet repair.

[@stirl22]

I'm a hgv tech. Our last generation Mercedes Actros had a pull type clutch, changed to a push type now though. Much easier to get the box back in! It was a pain to line the fork up on a pull type clutch. Also, put the valve lap tool in the end of a cordless drill, saves time and saves your hands 😁

[@seedster8597]

The appreciation of Harry's car the attention to detail is 👌 ian should be highly proud of his fellow employees 👏

[@ourfarmhouseinspain]

I'm watching this from Spain, which is no different to Italy with the August closure custom. The mentality is much the same as well, it simply wouldn't have occurred to the people processing the order for the gearwheel to point out the partner wheel would be required as well. You learn not to scream with frustration ! Brilliant rebuild, great to watch.

[@S-T-E-V-E]

Why don't you block off those front grilles inside if they don't cool anything and cause such serious problems?

[@arthurdardalis]

Iain is such a great guy, knowledgeable, patient and down to earth. There’s a myriad of issues for a 40k miles car but then again it is a specialist vehicle. Harry obviously knows “ball park” what the final bill will be but seems not too bothered… Great to see even if only a glimpse of one of my favourite cars, the Fiat 130 Greetings from Greece

[@LordandGodofYouTube]

Harry, I'm a trade-qualified automotive machinist (engine reconditioner) and when you change valve guides or put K-line valve guide liners in you really shouldn't be lapping valves like that, they should go to a machine shop and have the seats cut on a machine like a Serdi, Rottler, etc. When you put valve guides in they never line up as they did before with the only exception to this I've ever seen is on Caterpillar cylinder heads. You will end up with seats that are slightly wider on one side than the other, and you're missing out on a modern three angle valve job that will perform better than the original. Getting the valves ground and seats cut isn't crazy expensive, I could do each of those heads in around an hour each on a Serdi, plus around the same time to grind the valves. I would only lap valves if 1, I didn't have access to a Serdi, and 2, I didn't replace the valve guides. You're leaving performance on the table doing it that way, and the amount of time dicking around doing 48 valve seats it'll be more expensive and a much worse result lapping them. I'm actually shocked Ian is doing this, especially on a Lamborghini. I would never trust a mechanic to rebuild an engine, ever, they know how to do it, but often not the finer details which are important, that's why a lot of them bring engines to people like me. Also, I hope Ian checks the valve spring pressure before those heads go back together. You might think I'm just some doom and gloomer that always pops up in the comments section, so please give your local engine machining shop a call and discuss what I said with them to get another opinion.

[@pmel018]

Yes sir, lapping all those valves like that is archaic practice.

Love the workshop tours and road trips most of all Harry's video's. Being on the other side of the world, to see the French and Italian and European sites, landmarks and the countries themselves, is well worth the watch. The workshops tours show the mad engineering that exists in Italian cars, and the extremely brilliant English engineering that keeps them going. Love it all. Thanks Harry.

Typical Italian “solution”

[@mercedesw211classic]

But what about the compression ratio ?

[@johncrowley5612]

@@mercedesw211classic The engine has been stroked to achieve the increase in displacement. (It may also have increased bore, I don't know).

[@mercedesw211classic]

@@johncrowley5612 I looked it up. The compression ratio indeed dropped from 10.5:1 to 9.5:1, but they managed to achieve more horsepower by producing torque at higher revs and clearly having more mixture available...(bore also increased)

[@siraff4461]

@@mercedesw211classic Thats the static compression ratio but the overall active cr probably went up through having more time to suck the mixture in (larger stroke) and a higher stroke-bore ratio. Thats why it breathes better at higher rpm but would also ultimately limit maximum rpm. A better rotating assembly is how to get around that and they can then also use cams with more lift and duration but especially more lift at the ends of that duration. Again this would ultimately limit rpm unless better valves and springs were used. So generally this is a pretty comprehensive upgrade over the older 4.0l. Also dropping the static cr would help with running on unleaded and its lower octane numbers when it first came about - something it was almost certainly designed for since the seats are already capable. Its interesting stuff to see the engineering work arounds from those days.

I've seen those spacer plates before, i used to be into Hillman Imps and spacer plates were used on the big capacity engines, anything over 1040cc, they would go to 1200 odd cc with a spacer plate, they used wills rings (gas filled rings) to seal around the cylinders and thin head gaskets. I could never afford a motor like that (big money at the time), my Imp had a stock 875 Sport motor.

Remember the old plug in valve / valve seat grinder machine that most corner garages had, that you ground the seats on, and then you had a pointer gauge you set the valve side of it off of the machined valves so the angles were correct (opposite) . Thats the same problem as phosphor bronze seats you have with titanium valves is WEAR. Because they are a more durable metal, naturally they have a more abrasive nature on the valve seats, and frankly - most racers I have spoken to say Stainless valves work just fine
