Reassembling a starter.
« on: May 12, 2017, 19:43:25 PM »
My old MFA starter just stopped working, taking the moulding off the back of the starter I found a solder joint to one of the brush holders had come adrift. Great, 5 minute job. BUT - getting the thing back together is altogether different. I'm stuck.
Is there a knack to holding the brushes back against their springs so you can slip them over the commutator - or do they have a special bit of kit in the factory to achieve this?
Can someone remind me what I came in here for.

Hi

I sometimes tie brushes back against their springs with button thread and cut it off to release them back into position.

Would high melting point solder help it not happen again?

Push the armature proud of the case (against the magnet pull. Slip the cap with the brushes on the armature. Slide the armature and end cap onto the motor.
Lead, follow or get out of the way!

If it's the same as the mfa starter I had, pull each brush spring up and move so it rests on the top of the brush guide, assemble and as the end cover disappears into the casing, flick the springs back into the guide.

Don't know if its the same as the Kavan starter, but that has two small holes in the plastic end cap.The brushes are held back against their springs by inserting short pieces of piano wire through the holes before completing the reassembly. When everything is tightened up simply pull out the wires,brushes are released onto the commutator, job done
