Not all fully auto Hydracyclic Olympians have LVA45 (LVS45 for semi auto). The NBC for 1985 and 1986 Olympian deliveries specified the Lucas CAV 551 control system. Which could be semi auto or fully auto. These have an EPROM which was programmed with desired gearshift pattern based on the signal from the Transducer. Someone somewhere might still have the kit to blow the EPROM and more importantly to create the code for the EPROM. If anyone has I’d love to see it. These Lucas CAV 551 brain boxes where also used on the Routemaster refurbishment programme.
It's certainly a labour of love, tinged with a little insanity! Routemasters are very popular over here, and go for very big money, I think there's a few in Australia?
We used to have a fully auto LVA Olympian that used to slip like mad when changing gears so I used to use H to drive it like a semi auto, went like absolute stink! Nice one Matt, Lee really likes this!
What a wonderful educational video. For the time the controller was years ahead of its time really. I assume the same unit is used in a national 2. Years ago listening to rapid sliding gear changes from a N2 I wondered if a mechanic had maladjusted the controller to get faster gear changes. Looking at the circuit board I can now imagine it was more likely to be a dried out capacitor. Around bath and Bristol National 1’s were all converted to auto’s with the addition of a controller, drivers side, bay before the step above the window. These retrofit units were far less complex and didn’t feature throttle dip or pauses and must have destroyed many gear linings. They were all eventually disconnected. I note you have BH700 in the yard which will have this unit. Has anyone ever investigated the controller in there I wonder. Fascinated me for years now.
Pretty sure 700 was semi auto, although I could be wrong. It's quite a complex system for the era, but Matthew is better placed to answer that, I'm a zf man
@@adventuresinrust1644 yea it was originally. the retrofit worked if you left the gear selector in 5th the whole time it would work as an awful auto. ZF is on another level.
@rogermoore52 ahh, a it like London transport with the merlins and swifts? 4th was also auto. I do like my zf boxes, my bus has a 5hp500 ecomat with the est ecu. It's superb
The test button forces the unit to change from 2nd up to 5th and back again. You have to hold the button in hard and not let go until the test compeltes or the gods of LVA45's will punish you and lock the unit in 3rd gear until to isolate the batteries.🤣

Ended up listening to that with headphones on for one reason or another - and was transported back to my youth riding the bus to and from school

Enjoyed that!
i love how people lovlingly restore these buses i live in Sydney Australia and ive always loved the route master London double Decker buses

Always nice to see something fixed! Out of interest what does the test button actually do?
The test button forces the unit to change from 2nd up to 5th and back again. You have to hold the button in hard and not let go until the test compeltes or the gods of LVA45's will punish you and lock the unit in 3rd gear until to isolate the batteries.🤣
Have you found a circuit diagram for the LVA?
