These videos are fantastic! I've got a barnfind mk1 midget that I can't seem to get into reverse, all the other gears are fine. I've smacked it loads and it won't budge. Any ideas how to address that before pulling the whole thing?
As a wild guess I’d say as a barn find the The slider and spring which lifts to allow the lever over into reverse could be seized ??? If you take the gear lever covers off to see the box you can see the top of the plunger. Look at an exploded gearbox pic to see which one. Beyond that I’d take it out if it were me for the sake of a couple of hours . The rear housing can come off then to work on the reverse plungers . Thx for watching
@@mgmidget-thebirthofaraceca4349 Hey thanks for getting back to me! Funny enough I beat it with a 2 x 4 this morning with a bit of oil in there for a bit and it popped over. Going into reverse nice now
@27.33, F.Y.I that oval part on the side cover with the big hole in it was for the clutch shaft on the A30 as it was designed with a mechanical clutch, there is also one on the opposite side in the main casing & that was for the L.H.D version clutch shaft
I also have a locked up 1st gear and plan use a spacer as well. To what extent do I need to disassemble to free up the 1st gear? I'm hoping not to have to strip it completely as I want to get back on the road as soon as possible. Excellent videos, very easy to follow.
Olá! Pode me responder uma pergunta? Para trocar o rolamento do eixo primário, eu preciso desmontar toda a caixa para afastar o eixo secundário e retirar o eixo primário com o rolamento, para trocar ele fora da caixa? Hello! Can I answer a question? To change the primary shaft bearing, do I need to disassemble the entire box to remove the secondary shaft and remove the primary shaft with the bearing, to change it outside the box?
brilliant videos I have just taken my sprite mk1 gearbox apart you have been very helpful with your excellent description, shout out to eBay always good value!
This will help me out big time. Have not worked on gearbox for over 2 years. Had to return back to work and forgot where I had left off. At the time , your youtubes had not been posted. Thanks. Saved for references.
I’d say normal which for me was no obvious damage or pitting just heavy polished bearing surfaces. As the repair kit has the shaft and bearings they were changed out while it was apart. Thanks for watching
I opened up a ribcase to deal with the notorious locked in 1st gear syndrome. After fabricating a spacer to limit throw on the 1st/2nd shift shaft, your video helped re-assemble the unit, especially helping the sorcery involving the interlock balls. Thanks for the first class tutorial.
@@mgmidget-thebirthofaraceca4349 Thanks. Planning an engine and gearbox rebuild on my Midget. Really helpful video, very easy to follow how to disassemble and rebuild a gearbox.
What a great series of videos on the gear box. Nice job. Might give it a go. I have a ribcage in the corner of the garage. Maybe I missed it but did you check the clearances of the synchro gears with a feeler gauge to see if the cone part of the synchro gears were worn?
Thanks for the feedback. appreciate it! I did check the synchros but not explicitly on the video. Ideally you want a 0.8mm min gap between each synchro and the corresponding gear. Some say 0.025" as a cut off for replacement - as replacements look to be hard to source right now. Mine were ok and visually good, in fact i was surprised how good the whole gearbox was inside to start with!! Beginners luck i guess :-) Im hoping the gearbox it will replace will be as good on stripdown
`One of the best tutorials on here well done that man Thanks
Thanks appreciate the feedback

Terrific videos for the ribcase gearbox rebuild! Well done.
Thanks. appreciated :-)

Ups coming along nicely 👌
Glad you enjoyed the video. more to come!

If you need to get at first gear your really looking at a full strip down. Doesn’t take that long. Thanks for watching

Yes you do need to remove the box to take out the primary shaft

Just rebuilt my 1275 gearbox. These videos were great. Top man, Thanks.
Thanks for the feedback. My goal was to make the best resource out there to rebuild a ribcase box. Appreciate the comment 👍
Quick question…How much wear did you notice in the laygear? Was it significant or “normal”. If so what ia “normal” in your view ? Thx
I’d say normal which for me was no obvious damage or pitting just heavy polished bearing surfaces. As the repair kit has the shaft and bearings they were changed out while it was apart. Thanks for watching

glad i could help. thanks for watching
Does that input shaft seal modification need machining before fitting ? I guess the scroll needs machining away before the new seal can be fitted.
yes. i purchased the cover already machined and fitted with a seal online. thanks for watching

I have just rebuilt my Minor gearbox after watching your excellent tutorial,thank you.
Great to hear!
How long did you heat your case for with the heat gun?
not long about 10-20 seconds.thanks for watching

@@mgmidget-thebirthofaraceca4349 Ah nice job! Yah the box was pretty sweet. Can't wait for some track videos :)
Track videos you say..........hold my beer :-) give me 5 days ;-)
@@mgmidget-thebirthofaraceca4349 LOL
Yes a job I am not looking forward to thanks for your. Videos
Don’t worry. Step by step it’s not too bad just be patient and allow plenty of time
