I was riding my dads 270 rev3 when a crunch was felt/heard followed by a lock up! Anyway after stripping the gearbox we found that the water pump gear retaining pin had dropped out and took out 5th gear (several teeth missing!!!). I have managed to replace all necessary part except one, I cannot locate a 5th gear main shaft anywhere (part 18384918). I have tried Beta U.K. and numerous other U.K. based distributors, I even tried Bosi in Italy with no luck.

 

Anyway after many calls it turns out Beta are currently looking for a new manufacturer to make these parts hence no one has one.

 

So here I am desperately trying to find this part, someone must have one somewhere? an old Rev3 Gearbox sat in a box in the garage? a Supplier I hadn't thought of?

 

The old mans bike has been sat there for nearly two months in bits patiently waiting to be fixed.

 

Any help at all would be thoroughly appreciated

 

Cheers Guys

 

(I believe it is the same part on 250/270s from 2000 to 2008)

You might find the evo shares the same part

Try Allens used trials parts http://www.allensusedtrialsspares.co.uk/

You could try John from beta new Zealand, John has mountains of old beta parts stored in his shed you may get lucky NZTrials@xtra.co.nz

Thanks Guys, I will give them a try today

I have a couple of late model techno gearboxes. I would think they are very similar if not the same.  I can post you one out to see.
