JAWA 250 gearbox cutaway - How a manual transmission works 

Thank you. If you want to put bigger exhaust pipes on a vintage Jawa, you’ll need more space between starter lever and exhaust belly. That’s the main reason why I changed it.

Thanks Mate 👊🏼🤝

Thanks for watching.

🤟🏼👍🏻Thanks Mate

@@Quiet.Light.Engineering May I know you belong to which country? And if possible try to make a video about how to repair Jawa vehicles on our own for the basics instead depending on mechanic. And what needs to be checked if we face starting trouble etc,. You can try making this as a series. It will be very useful and thanks for your time to post these kind of videos and educating us. Much appreciated my friend. Love from Chennai, India.

Thank you, Sir.

Thank you.

Thanks. You are welcome.

Thanks for your multiple feedbacks!

Most likely you will have to remove the engine and split the casing. The JAWA gearbox is simple. It will probably be obvious what‘s broken if you have the stuff in front of you.

Siegfried, thank so much for the response. Sounds like a good winter project to take the motor out the frame, open it, try to see what needs replacing, order some parts and put 'er back together again. I am okay with taking the engine out, but before I crack the case I want to know a bit more about what I am getting myself into, so trying to find a good video or two (in English) that show the process of splitting the right hand side of the case. If you or anyone reading knows of one, please let me know. Really appreciate it!

No, it is not easily possible to put a 6-speed gearbox into the old Jawa engine case. Better to swap the entire engine with modern hardware in this case, or go for another bike.

@@Quiet.Light.Engineering Thanks for information!

Hi, what exactly do you mean by sequence?

I mean the sequence of gears are they 17teeth gear on main shaft with19teeth gear on lay shaft and then 20teeth gear on main shaft with 16 teeth gear on lay shaft ...is this right?

Standard sequence is as follows (without adding layshaft ratio): 1st: 12/24 2nd: 16/20 3rd: 19/17 4: 1/1 For closer ratio between 3 & 4 one can change as follows: 1st: 12/24 2nd: 17/19 3rd: 20/16 4th: 1/1

Which sequence is best and what sequence did you use in this video?

Thanks alot bro for information on both the sequence ..there is confusion as to what is right..

Thanks a lot, Mate.

Thanks for watching. As you can see at the beginning the casing was broken…

@@Quiet.Light.Engineering We still take these arteries for a lot of good. No hard feelings. Otherwise you're the jawi guy to make such a runaway cannon 🙂👍

Thank you, Sir.

Спасибо за комментарий. Нет, я предпочитаю поручить сварку нескольких двигателей и т. д. Аллану Мильярду.

Thanks for watching. This old type JAWA gearbox is correctly put together. Hardly possible to do it wrong.
