Twins / Re: A65 OIF conversion to disc front brake.
« on: 16 December, 2017, 17:20:54 »
AFAIK a complete T140 type front end will bolt straight up.
You have to use the T140 type yokes as the fork tube centres are further apart on the disc front ends.
There are no mounts for the wire type headlamp brackets  on the top yoke but nobody seems too fond of them anyway.
The '71-2 mudguard won't fit without bending out the wire stays, but again, nobody seems to be too fond of them either.

Twins / A65 camshaft pinion extractor

Can anyone please let me know what the extractor threads will be on a 1966 camshaft pinion ?

Thanks for all the advice.
It looks like a stage 3 job to me.
I think that I know of an engineers in the Midlands who may be able to help me out with this.
If they can't they will be able to point me in the direction of somewhere that can.
I think I'll have to get a small amount of weld added around the outside face before machining starts.

Twins / A65 extreme spark plug thread repair
« on: 30 November, 2017, 14:09:20 »
I've just got hold of the correct OIF type head for my A65 project.
One of the plug threads has been butchered by a drunken gorilla.
A standard helicoil just isn't going to be possible.
By the look of things either the hole is going to have to be completely welded up and re-machined or some sort of substantial insert fitted.
Any recommendations please ?

Twins / A50 Barrels ?
« on: 25 November, 2017, 12:44:47 »
OK folks.
The first of my dumb questions.
Is there any way that you can bore out or fit oversized liners into an A50 barrel to give a 75mm bore ?

I'm guessing that the answer is probably no, due to the casting being different, but I thought I'd ask just to be certain.

The Star and Garter / Re: Fuel Tanks (again)
« on: 25 November, 2017, 10:42:47 »
I think rather than pay  190 to have an existing tank sealed, I'd buy one of the Indian offerings and then seal it on arrival with a proven quality tank sealant.
They've been known to have porous seam welds which will soon have your nice new paintwork bubbling up, but a good tank sealant should prevent that.
Not really good engineering I admit.
But how much for a quality British made new tank ?

I haven't had the time to read through all the small print myself  (who has?)
But I believe that complete vehicles are  not covered by the Paypal money back guarantee scheme.

I keep hearing of people using a product called POR15 as a tank sealant.
It's actually meant for the painting of vehicle chassis and components, but it's supposed to be an excellent tank sealant too.
Expensive by paint standards but cheap compared to  190 I'd think.

Twins / Identifying the age of a unit bottom end.
« on: 22 November, 2017, 19:44:01 »
I've got a unit twin bottom end which was purchased from a breakers.
There's no engine numbers stamped on and no sign of foul play either (no sign of numbers being removed)
It's substantially all there  with only the primary outer cover and outer timing cover missing.
I'd like to get some idea of the year of manufacture based on the features present.
Possibly a pointless exercise because it may be a complete mongrel itself but here goes.
Crankcases have 5/16" barrel studs.
Alternator stator mount is the cast alloy type.
Gearbox filler on crankcase
Timing plug plate front of TS crankcase.
The inner timing cover has the early type clutch actuation
Speedo drive bulge on the casting but not machined out.
The clutch is a 3 spring type.

Working from Roy Bacons restoration book I'm thinking about 19966-67 maybe ?
Any other opinions welcomed.

The Star and Garter / Back with a basket case
« on: 22 November, 2017, 19:09:25 »
Hello to you all.
I haven't been on here for a long time.
Long ago I had a 1948 B33 project which sadly I sold on to finance another project.
I have now acquired a 1972 A65 basket case.
I've got a complete rolling chassis but only half an engine so far.
This is a "back burner" project and I'm in no particular rush to get it finished, as long as it keeps inching forward.
I pick up bits now and then usually private sales.
Consequently what I have is something of a "bitsa" at the moment.
Please excuse any stupid questions I might ask - I'm a bit rusty on BSAs at present.
