Alternator to a Villiers 2T

Post  Guest on Mon Aug 16, 2010 12:13 pm

Hi All
I want to fit a Lucas or Wipac alternator to a Villiers 2T (or 4T) engine.
This would replace the Flywheel and back plate(with the coils) and it would then be set up as coil ignition and charging from the alternator.

Has anyone thought the same or actually done it.????

If so are there any tips for me, I am prepaired to do some machining.

I await your response.

I can't find the article where the honda unit was used,i think it was our ex-chaiman Jeff Venning who was doing this,however there is a two page article showing a similiarconversion using a lucas RM21 alternator and rotor,and the associated machined parts,this is in the winter 2000 edition,if you send me a stamped addressed envelope,i can send you a copy of it,JH

Every day is a school day? i knew they used a d.c. siba generator coil ignition set,and a dc remote coil on T series twins,but a lucas alternator?? i don't think so,it was against all their principles of in house manufacture,but i have been wrong before,more details please,JH

Villiers high output generator

Post  FB vincent on Tue Jan 25, 2011 9:06 pm

As JH says, some engines were fitted from new with external dc ignition coils. My ex Police 4T engined Cruiser 89 was built with the Villiers high output generator, all the generator coils being used to provide rectified current. Sandy Ross

Villiers High Output Alternator

Post  j wakefi on Tue Jan 25, 2011 9:22 pm

A wiring diagram of the Villiers high output alternator with battery powered ignition coils is on pages 62 & 87 of the 4T Workshop Manual VEC 641. All 4 coils charge the battery via rectifiers. Still 6 volt though. I believe reprints of this manual are still available from Villiers Services. Well worth having.

Alternater mod for 2 and 4T engines

Post  Guest on Wed Jan 26, 2011 9:07 am

Hi j wakefi

That is how I have wired up my 4T engine and it works OK.
But the mod I was thinking of is using a modern lucas alternater,the same as my 87.

Presumably the advantage of the Lucas one would be to convert to 12 volt. I wonder if you can do this by re wiring the coils in series on the Villiers one & using a Zenor diode to regulate charge. Would save a lot of modification.

You can convert to 12 V. DC using a Boyer Bransden power box PBX 00 108. This will rectify and regulate from the 2T alternator.

Conversion

Post  kerabo on Sat Jan 29, 2011 5:25 pm

Dont you think tht by removing the mass of the flywheel you would upset the smooth running of the bike. If I understand this correctly you will fit a central rotor? It would be hard for this to have the same smoothing affect as a larger diameter flywheel.

Just an oberservation

If you think about it the AMC engines have all got the lucas or wipac alternaters and they run OK, which is the same arrangement that I am thinking of for a 2T or 4T villiers engine.

I will however look into a Boyer power box arrangement.

Hi

Yes that crossed my mind while i was writing but the AMC engine was made for that set up. You will possibly feel no difference but i know from experience that on cars you cant mess with such things without resluts on uneven idle.

Hi Ken

Way back in my youth I too played around with my Austin 7.
Having blown up two two bearing Austin engines I put a Ford 803cc engine coupled to an Austin 7 4 speed gearbox in the Ruby and machined a considerable amount of metal off the flywheel thinking it would go faster. ( I managed 70mph out of it before it started tramping all over the road.) so I gave up at that point.
I would put up with a little uneven tickover but it could rev better.

That's my life story.


Regards

Ken

The Medway Towns are in the sunshine state of KENT along side the river Medway.

My first three cars were Austin 7's I sold the last one for 25 and thought I did well. (that was in the 60's.)

Now all I can afFORD (no pun intended) are Francis Barnetts.

Wo is me.

Post  kerabo on Sun Jan 30, 2011 10:32 pm

Mine was a Standard 8 Cost me 8.00 in 1967. used as much oil as petrol. Had so little compression I used to park on a slope and push ram it in gear and jump in when it fired. Morris Minor, Austin Cambridge,Hilman Minx, Hillman Avenger. Transit van, Rover 200TC but I fitted a Perking 4108 deisel Volkswagen Beetle,Ford Anglia,Austin Maxi, First ride on a bike BSA Bantam on pillion and I was hooked. First bike on the road AJS 350 Passed my test on a mates C15. Second bike BSA A10 Sad to think of the classics we wrecked on the fields.

If we could only have them all back eh lads! Very Happy

My first bike was a mobylette auto moped, but that was soon replaced, I had loads of bikes on the field, C15, bantams, various mopeds and a Yas1 yamaha, about 4 lambrettas and a vespa, well many bikes, till 1975 when I got an FS1E Yamaha, on the road ever since with too many to mention, my fave bike was a YDS7 Yamaha. First car was a Mk1 Escort van I got for 60 quid, oldest car was a Ford 100e Popular that cost me 25, and my favourite was a 1979 trans-am 6.6ltr that cost a lot more.

When it comes to French motors, I used to have a rather strong desire for a 2CV Pete, and also, a Renault 4, but never got either. I was too immature to bear the potential criticism and mickey-taking way back then! Laughing
