Ferrets are so much fun to drive. I was told by my museum buddies that it has 5 gears forward and 5 in reverse so you can get out of trouble as fast as you got into it.
Neat! I remember seeing preselector gear boxes on 1930’s Rileys when I was a kid. It seemed like a good system.
Extra grouse! Till now pre-selectors were a complete mystery to me.
Well it's an interesting but a bit complicated gearbox system. Thanks for your great explanation, surprisingly well done, you would make a great teacher ! 😊
Thank you. Intriguing technology.
Hi Lottie, firstly - please don't call it a "clutch pedal" - for the reason you explained! You are right, that gearbox was used in Saracen and Saladin but not Stalwart, which had a Meadows manual gearbox. The bar that runs the length of the gearbox and is connected to the big spring in called a busbar, when, as you explained, the driver does some sloppy gear selection and no fingers engage with the busbar, allowing it to rise fully, that is called a "false neutral" and the reason the pedal is then so hard to depress again is that big spring is rated at 960lbs! Due to a change in leverage the higher the busbar is the greater the force applied by the spring. In a Saracen this usually traps your left foot between the pedal and the steering cross-shaft so you have to get your right foot over to press the pedal to get your left foot free! The hole in the top of the bellhousing is so you can access one of the bungs in the fluid flywheel to screw in a schrader valve for pressure testing the flywheel. I look forward to you explaining setting the busbar height and hope you have a very strong left leg!
Thanks Lottie!!
Great job Lottie, mazing video and thoroughly explained! x I love watching your videos and look forward to watching future videos! x
I drove a British collector's bus in France for a long time equipped with this type of gearbox and a Gardner engine with the difference that the control was electric and an electromagnetic clutch. Thank you for your fascinating videos.
A bit overwhelmed. Usually I can follow along but this is first brush with a gearbox. Enjoyed the video either way.
Well explained, learned some new stuff about this gearbox, is very interresting, greetings from Belgium, Europe
I'll join that comment from your neighbour, little Luxembourg.
Great explanation.
Wow, such a complex unit for a small armoured car, well explained, good job.
Very good explanation. It's the first time I have seen the internal workings of the box but have ridden behind one many times
They used the Wilson pre selector gearboxes in the corporation busses where I live in the UK from about 1935 up to the late1960s
It's a good reliable system especially when coupled to a Gardner diesel engine.
Got a ferret in our museum, I'm gonna have to do some work on it one day for sure
Thanks for the good explanation.
I'll now be looking for a way to insert "anti bugger it up device" into my conversations 😁
Thanks
Very well done greetings from Vermont
“Of course the sun has to come out now!” - daylight interfering with Lottferatu at work :P
What an over-complicated contraption just to change gears, they could have used a clutch with a heavy-duty truck 4 or 5 speed gearbox mounted on its side to allow the shifter to come out as a long rod up to the driver's position. But, it's a good video and learned a lot about the Ferret pre-select transmission.
I remember riding in Sydney buses a long time ago, wondering what the go was with the gear shifting. Now I know a bit more.
Great video very informative nice job thanks good British stuff 👍👍👍👌👌
its a wilson type semi auto,air shifteed in trucks and buses,i have rebuilt quite a few,including the angle drive units found in leyland atlatean double deckers
Lovely video. I imagine you have many men in awe. Dream of a woman that has some mechanical knowledge.
Clear story, thnx😀
Hey up Lottie nicely explained mate
Very interesting gearbox design. Actually, it's pretty groovy. I like that someone else besides me likes to use that word. 😀
Hi Lotte, Are you going to go through band adjustment with the "Special Tool" ? Would be great to see a Video of it !!
I don't have one,but I do have a 82 delta 88 royal with a bullet hole.🤠👍
Excellent tutorial, even though I don't drive a car (everywhere by bike) found this to be very informative. So does this mean you're impressed by the mechanical side of the Ferret as opposed to the electrics?
😄😄😄😄👍👍👍👍👍👍
The German Tiger I tank was preselect too, supposed to make it very easy to operate these boxes.
"Follow me so far" 😆😆😆
Yes the Tiger's gearbox was preselected but was hydraulically operated and partially mechanical with the positioning of the selector. It made the driver's life easier but it was very expensive to produce and needed highly experienced mechanics to mantain. Sometimes I do wonder if it would have been better to install a manual gearbox like the Panther or the later variants of the Pz.Kpfw IV...
Thanks Lottie! I now have a slightly better understanding of how a pre-selector gearbox works. All I knew previously was that it involved epicyclic gears and brake bands. Now I have a bit of an Idea about the selection and change mechanisms.
Great channel!
Great video, I was wondering how the gears themselves were setup, is it a sun gear arrangement or something else?
One question. So if those are stacked planetary gear section, I take it that 1ST ( super low ) is all the bands squeezing on all the sections to get all planetary working for max torque. Then 2 , 3, 4, and 5 is just releasing the tension off a section to get a faster and more drive out the main input shaft and not all the gearing ?
I'm recycling wood 😂 old pallets into the inner walls of the funhouse
hi lotti are you anti brit or just anti brit armour
sorry Lottie
Thanks
