Hi there there that sounds great .just one thing is the large thin bearing ok ...
Here is a few photos of the motor take note of the keyways
Please note the motor has not been cleaned or restored just striped it down and built it up to show how it goes back together
The first thing is to place the two thin washers at the bottom of the alloy part put a little grease on them to keep them in place
Take note of the red positive cable of the left side and which way round each section goes check the marker pen marks
Put the rotor in the lower part (alloy part ) making sure that the washers are still in place .ps you can put the brushes in last
Then place the steel tube over the rotor but be careful as the magnets will stick to the rotor try and keep it from touching the rotor and pulling it out (I always place the alloy part in the vice ..make sure that the keyways are in the right place ......
The next thing is to fit the plastic part the one that has the fingers that holds all together when the 2 long bolts are fitted .
If all goes well then it's the gearbox insert and the gearbox outer case to be greased and fitted again there is a keyway on the gearbox outer case
And on one of the fingers Make sure they are lined up .
Ps I missed out the long bolts but it does not matter as it will be striped down again and serviced .
Bye Chas
