Recently when i started my A2 sounds like the starters still spinning for a few seconds after the engine started (ralph first noticed it the other night) took it all apart today couldnt find nothing wrong but when i torqued up the rotor bolt the large cog on the end of the crank feels like its binding when you spin it backwards.

Mikey, there are only two things that usually go mechanically wrong with this starter mechanism.
1. The three cylindrical bearings become worn and lose there ability to drive. Also, the mating bearing face becomes worn.
2. The seal (oil slinger/ damper) behind the larger gearwheel is not correct. These come in three sizes. I have skimmed them down to fit, however, they are designed to just cause a drag on the gear wheel. and stop it rattling. Check the the two phophor bronze bearings are correctly placed. Test the lock up without the woodruf key first, to ensure it is correct on taper.

Thanks garn its just started doing this so i would say the seal you mention is correct as i havent changed it, and as per the clymer and haynes manuals it all looks assembled correctly but i did notice the area that the rollers run in is a but rough

Mikey, this is a common fault/problem and Z Power (...etc) do re-build kits
If the 3 x roller surface is dodgy, then thats most probably the cause

Ok cheers piggy got ralphy coming up this afternoon for a look
see what he thinks done me fork seals yesterday and paint work
coming back tomorrow night just me lecys now for the rally

3 cheers for king ralphy he sorted me starter today cheers ralph your a star
and i promise to get a new gasket and a helicoil kit for that thread and not just put a longer bolt in it

Good to hear that the problem is solved Mikey, I think it's great that folk from the site can help out in not just advice, but actual hands on stuff.
What a club!
Take a pat on the back to all that contribute to others enjoyment when the going gets tough with their help and advice.

Well done Ralphy, Just for the record, what was the starter problem? Was it the 3 rollers?

Nah, it was the damper jobby. It was just a bit too tight. I think a jump to another size would have been too much, so I just fettled it down a bit on Mikey's missus's kitchen work top ( the only available flat surface - she only complained bitterly for a little while until she realised she was out number by oily gits) with some aluminium oxide paper using the figure of eight method. I should have preferred to have been a bit more scientific using accurate measurement and my centre lathe, but the best Mikey had to offer was a rusty steel rule and some emery paper ... still it worked!

Mikey's missus kept the tea flowing at the correct intervals - constant Still Mikey's Zed will soon be in my workshop where I will ensure she is ready for the expedition to see if there is intelligent life in the far north
