ok here goes...

the motor died in my 71 beetle , so i have a 62 beetle sitting about with a strong 12v later model 1300 twin port in , so i pulled it out yesterday and slid it into my 71. all is good , runs sweet as a nut , the only problem is when you turn over the starter motor it makes a horrible noise...

are there different starter motors with differnt teeth???

the starter on the 71 is almost new...should i pull the starter out of the 62 and put in the 71 to match up with the fly wheel on the motor i pulled out?????

Spriggo

yes there are different amount of teeth both on the flywheel and starter gear for 6v and 12v

you will buggar the flywheel if you leave the 6V starter in place

Was the 62 converted to 12 volts along with a 12 volt starter motor. you could fit the starter from the early car if the gearbox has the correct bush fitted

You may have to pull the motor again and swap flywheels,if the other car had a 12v starter it would be the same as on your 71.The early starter had a bigger pinion shaft. The other option is to get an auto electrician to fit the later pinion to the later starter. Flywheel swap is the best option.

thanks guys.....thanks for all the advice..

yeah swapping the fly wheel i see is my best option....

oh well ..something to do over easter

If its a later 12v 1300TP, and you're fitting it into a 71 12v beetle then you shouldn't have to swap a flywheel at all.

A 1300 TP should have no problems with being fitted to a 71 beetle......unless its been fitted with the early "O" ring 6volt (200mm clutch) flywheel from a type 3. Why would you change the flywheel Grumble ??

You may find because it was fitted to the 62 that its a 6 volt flywheel modified to fit the 12 volt crank so the original 6 volt gearbox and starter can left alone, that's probably why it's not meshing with the Sbug starter.

why can't you use the starter of the early car by changing the bush in the gear box

Why would you change the flywheel Grumble ?? that could be the exact issue there craig... the clutch that was in there is a 200mm with the early centre ring on the pressure plate..the clutch on the 71 is a 180mm. i have no idea on the history of the 62 but i do know it was converted a long time ago.my thoughts are if i change to the original fly wheel and clutch, i know its all matched to the 71 starter. and while im at it i can put a new bush in the bell housing to make sure ????? whats your thoughts???

Remove the starter from the early car that originally worked with the 1300 engine and fit it to the later car , a change of starter bush in the gear box if required would complete the installation, this is as you suggested in your original post.

Beware if swapping flywheels...reset crankshaft end float.

it would be cheaper in the long run to get the origional starter over hauled or buy a S/H one

Ok lost of Interesting replies here.

it seem i have a 6v fly wheel on the later twin port motor. this seem to be the only thing that makes sense to me. i have ordered a 6v to 12v bell housing bush and a new 12v bush just in case. i have also ordered fly wheel locking tool as a worst case senario i can pul the 12v fly wheel the motor that came out and refit to the new motor which will match it up to the 12v starter. this has to be my problem....nothing else makes sense .

also for ref as mentioned above, with many years of playing with VW's mainly post 68 i have come across many many 200mm and many many 180mm fly wheels too on various motors from various years , but having never really played with early stuff i wasnt aware of fly wheel differences .

you live and learn i suppose..

i'll keep you updated of the final out come.

Thanks for all the Advice.

No Grumbles the big shaft won't fit into the small bush, As i have said in my previous post just change the bush, just change the bush and fit the earlier starter, i run a 6 volt starter for years with no problems.

all these post's about putting your big shafts into a small bush is getting confusing

I was running a 6volt starter on a 180mm 6v flywheel for a while (system converted to 12v and a 12v solenoid off an early holden)

It was a great set up, motor got going in the time it takes to blink. No chewing of ring gear because the holden solenoid threw the pinion gear at the ring gear at a much slower speed. Once the gears were engaged the 6v starter spun the engine like buggery.

Then I did a gearbox change, 1500 box with 12 volt bush. I didn't like the idea of the conversion bush with the 6v inside diameter and the 12v outside. The wall of the bush was too thin for my liking and I thought I would end up having to change it too often.

Instead I pulled the 6v starter apart and had the armature end machined to match a new 12v bush. Didn't cost much and I was able to fully recondition the starter in the process.

That particular flywheel should never have worked on my 1300tp as it had no O ring. But somehow it did manage to work for years without pissing oil everywhere. It had been on the car when I bought it. I later swapped it for a 180mm 12v ring gear as per original and had to put a stock 12v starter in.

Just goes to show there are lots of combinations out there.

Matt.
