Hello folks,
Excuse my ignorance but after searching around on the forum for abit I couldn’t find any information about taking the starter motor apart.
I remember years ago coming across a guide for it but no such luck.
Much appreciated if anyone could send me in the right direction
Thanms

Re: Starter Motor Rebuild
I know of the same guide, think the pictures are long gone.
I've done it before, and it was a giraffe, as you have to get all 4 carbon brushes past the commutator.
You can use toothpicks or thin crocodile clips to hold them back on reassembly, but it's very difficult still.
Word to the wise, when I did mine it never worked properly afterwards, had to buy another one

Re: Starter Motor Rebuild
Not a problem, thanks for the reply Banner.
Did you get a new motor from somewhere or was it 2nd hand?
Obv Kwak don’t do them anymore (along with original coil packs, hence my other posts about changing to stick coils but I think stick coils will fry the Igniter due to their secondary resistance and feeding a pulse back into the igniter)

Re: Starter Motor Rebuild
2nd hand one from ebay.
I was trying to sort out my starting issues, and thought it might be the motor...turns out that new battery leads and a much higher cranking battery (175cca!) fixed it...

Re: Starter Motor Rebuild
Ah yes I happen to own a set of you’re much improved battery leads.
Maybe a higher cranking battery will help as well

Re: Starter Motor Rebuild
Is the YT12A-BS a straight swap banner or did you need to lift the battery up to reach the cables etc?

Re: Starter Motor Rebuild
Straight swap, it's the same dimensions as the oem, and the terminals are in the same place
