Burman Gearbox Series ‘A’ Twin Gearbox Type

[Phil Davies]

A quick question, is the gearbox for an A twin a Burman X1BAPDH type and if so does it have the same push/pull adjuster as Ariel - ie a pin in the top mounting casting that attaches to a threaded bar that has a collared adjuster on it, the adjuster locating in a frame/engine plate bracket?
Bit like the attached image!

That's of it my handsome. Make sure the link holes are a good fit on the pin as you don't want too much slack. I did Route 66 (in16) and Tassie Tour (in 17) and N.&S.islands in NZ (in18) and never had to adjust them, just made sure they were tight.

My answer is a little more simple

Thank you gentlemen.
I am clearing out (well starting to) my garage now and it's one of the items on that voyage of discovery in long lost corners!

My answer is a little longer. 'A' Twins had gearbox number prefix 2XBAPH (yes, usually followed by a number 5****). That's not to say people haven't fitted other types which are close.... at risk of some misalignment of chains.

Moreover, that mainshaft looks waaaay too long at the drive end. I'll try to find mine tomorrow and post a picture... (Sorry Robert/Phil !!).

Ah, thanks for that Pete.
The prefix 2X....... is a bit of a giveaway then for me.
Ah well, I remember picking up the box years (and years...!) ago, I knew one type of bike it fits and vaguely remembered something of the 'XBAPH' being related to A twins - hence the question.

Don't trouble with getting pictures, I'll take it as not A twin.
Cheers, Phil

I did notice the looooong mainshaft, but was really only answering the questions about the adjuster being like an A twin. I had my shortsighted glasses on this morning!

Robert, clear the frost from your glasses. Brrrrrr! Cold in the PNW this morning. When is it going to rain?
Shadow is ready for road testing. Carbs are squeaky clean with new petcocks and screens.

Not sure how Bill ended up in the "Tech. Advice: Series 'A' 500cc/1000cc Bikes " department. I guess the cold weather in the PNW (Pacific North West of the US) must have frozen his brain. Here in ther Balmy PSW of Canada we are enjoying delightfully sunny weather. In fact I had the topless MGA out for a pleasant drive to breakfast yesterday morning. Most Invigorating!

Perhaps a Mod could find a more appropriate spot to which this highly exciting post could be moved!
