	Hi all, This is my boss' truck but myself and Sam try to help him with its issues. It's been imported from India, I don't think there are many in the UK. It's powered by what I am told is a single cylinder 4 stroke diesel engine linked to a sequential gearbox, and therein lies the problem. About a year ago, the thing seized up and wouldn't go into gear (Or was stuck in gear, it was a long time ago and I forget). So, we took the engine out and the bell housing of the gearbox off... Above picture: Sam's pants. A lot of metal pieces falling out of the box was a clue It appears the speedo drive worm gear has shattered, the ball bearings that it rests on have shot out along with the springs and been munched up. We've tested the gear stack out by hand and it now engages and rotates, so hopefully we've cleared the debris out. So, we have a broken speedo drive and I don't speak the manufacturer's language. Part of me wants to reassemble it without the speedo drive and just see what happens, but it seems to form part of the gear stack and I'm wary of putting unnecessary pressure on the other bits. Does anyone have any experience of these? Or what might share the same gearbox? They are designed to be fixed by the side of the road, so I hope we can find a solution. Thanks!

	Hi, Is it entirely different from the Piaggio three-wheeled thing ? While searching on google it appears the two companies have collaborated in the past, it might be worth looking in this direction. Good luck!

	Thats pretty damn cool. If you have a uni near by you may be able to get one of the international students to help you with translation, our summer intake is usualy students from India & Malaysia so you never know - may save you a headache.

	Cheers! Yeah good idea. I don't know how similar they are to piaggios, I know that there are at least external themes, unsure about mechanicals.

	A very big number of Indians speak excellent English - I think it is still one of India's official languages, so communication really should not be a problem. Nick

	Bajaj Auto used to produce the Piaggio Ape under licence from 1959 to 1974. After that, Piaggio set up Piaggio India to produce the Ape themselves. Somehow (no doubt due to murky legal wranglings), Bajaj were able to carry on producing thier version of the Ape without a licence, and still do to this day. The diesel model you are looking at is the Bajaj GC 1000. The Piaggio Ape uses a common gearbox and crankcase casting that the cylinder barrel bolts onto the top and the diff unit bots onto the back. This probably isn't the case for the Bajaj diesel version as it uses a bought-in Kubota engine. However, after looking at your photos and a Canadian website I found that offers spares for the Ape (www.kjjohnson.ca/piaggio/parts.php) it looks like the contents of the gearbox are very similar to the original Piaggio design. Look at this scan of the exploded diagram of the gearbox (kjjohnson.ca/piaggio/Parts%20Photos/Picture3.jpg) - the components do look very similar to what is in your pictures. I'm guessing that part 14 in that diagram is the speedo drive gear that's shattered in your gearbox? Unfortunately that site doesn't have any gearbox parts for sale, but it might be another avenue to look at. Regarding dealing wirh India, it shouldn't be too much of a problem as English is fairly commonly spoken in business. I've found this spare parts supplier that it might be worth dropping an email to at least - www.indiamart.com/pritamoverseas/threewheeler-spare-parts.html
