WANTED - A10 Plunger Crankcases

[MidlandsA10]

Good Evening All

I am new to this forum - and will post an introduction properly shortly.

I am looking for a set of crankcases for an A10 Plunger (1954).  Any leads would be gratefully received.

Kind regards

Tom

G'day Tom 
BritTwit in the US had a set of earlier (same ex for #) cases. https://www.a7a10.net/forum/index.php?topic=16009.0

  Tom, where are you?

[MidlandsA10]

Hi both,

Thanks for the quick reply - I'm based in the UK, more specifically Leicestershire.  I'll certainly consider having some shipped over if there is no option closer to home.

Thanks,

Tom

Hi Tom, I have a pair of matched 1950 plunger cases if that's of any interest. I m based in Hessen in Germany.

Hi Jonny,

Sounds great. Are the 50's cases the same as the 54?

Can you please inbox me with how much you are looking for, for them? I take it they're in fairly good condition?

Many thanks

Tom

I think that you will find that 1950 cases don't have the relief oil feed to the timing gears and cam tunnel.

 That's correct Trev. They don't have a crankshaft oilseal either. Case series for later engines is BA.  AA Series is the Unicorn variety..... I'm wondering why our new member Tommo is in need of cases, has another major disaster occured? Unless its a desperate need these cases still turn up from time to time on ebay, so worth waiting for.

Hi~ I am new to the forum too, I just bought a 1952 golden flash and it came with a set of matching crankcases. I am in Plymouth UK just in case!  I would want £150 for them. Number on them is BA10 14365.

Thanks for the reply - no major disaster fortunately.  I bought a plunger frame/forks/wheels which I've been tinkering with (powder coated the frame black, stainless spokes in the wheels etc).  It didn't come with an engine so that's the next logical step.

Resto_man, I think I know the A10 you purchased - was it on eBay a month or two ago?  I spotted it came with a spare bottom end.


Would you take 120 if I came to collect?

Many thanks

Tom

Hi Tom  Yes your right that's the bike I bought, just needed putting back together. Yea right!!!!!
I want £150 as that's what they seem to be going for, they are in verygood condition no damage and all threads good. If your interested give me your email and I can send you some pictures. I did try putting some on here but it said file to big or something?
Cheers Tony

Thanks!  I've sent you a DM.

Swarfy, why do you say AA series cases are rare?
Only used on short stroke A7 in 1951-52 but not particularly rare.

[Swarfcut]

Trev, You will find AA7 Cases a' plenty for sure, but you won't find a genuine AA10 Crankcase, so my comment was a bit tongue in cheek and posted as a bit of light relief.....

 For a rebuild any plunger  A7 or A10 cases will do as the castings are identical. Later cases have improvements to the design but early ones work well enough for most folks.

 Get finance arranged Tommo. You'll need a big journal crank, pistons, rods, thick flange barrel, alloy head. rocker box and a SRM pump, timing gears, maggy, dynamo and carb. as well as the cases. Compare this to a complete engine unit which may or may not (lucky find) require major work and you can see that buying a lump works out a good deal cheaper. Horses for courses, depends what you want, a nice leisure machine or an out and out screamer with all the bells and whistles.

 Swarfy.

You're not wrong. Buying an engine (or bike!) in the manner of Johnny Cash's Cadillac takes time, effort and too much money.
It's buying all the little incidental doo-dads that soon mount up to big money, so I'd always buy a near complete unit (even worn out) in preference.
Are bare cases really making £150 now...?
