Bis Starter Motor

Hi

Can the Bis Starter Motor be rebuilt as mine is playing up!

Thanks

yes

Mine developed a problem, sometimes it wouldn't engage, just spun and spun in fresh air.  I tried taking it apart a few times but couldn't find or solve the problem, so I got a new secondhand one via breakerpart.co.uk or similar for about 50 quid (which i thought was a bit expensive but a new one was very expensive if i remember rightly).

 I think the later air cooled one is the same as the bis.

Thanks guys!  So what needs replacing and cleaning and how good will it be when done?

If when you turn the key to start and you can here the starter motor turning but it does not turn the engine, then the most likely cause is a faulty solenoid, That is the bit that's mounted on top of the starter motor, They were used on the aircooled and bis from 1987 onwards with key start instead of the lever pull mounted on the floor, There 23 euros from 126fan plus Postage.
I had to replace mine a few years ago and haven't had a problem since, But i think that's because i also fitted an electric petrol pump at the same time so it starts immediately and doesn't need to turn the engine over and over to pump petrol into the the carb.

Once and a while when I turn the key to start, nothing happens, apart from a"click" sound. Although on the second attempt, 10 out of 10 times, it starts straightaway. Is this an omen re solenoid?

Mine did this for about six months and now it is shot!

yes, a faulty solenoid. contact plates inside the solenoid that transfer the voltage/current to the startmotor is dirty og corroded, so its not always it transfer power to the starter.
