[Mg-mmm] P-Type Dynamo.

[Chris Bucknell]

HI Jason,

Bear in mind that I prefer to do most of my own work BUT I feel this one
falls into the specialist help required category.

I just went through a similar exercise on this with our P and I know the
auto electrician had to speak to his Dad about it and they hand filed some
larger brushes to fit.

If it is out get the whole thing taken apart and check bearings.

At the same time check the various modifications cylinder head seal to
prevent oil leaks in future.

Definitely need to adjust on bench tester before going back into car.

I have got a few docs on generators if you need.

Chris

Hi all!

Working on solving a dynamo problem on a P-type, PB engine.  Unit does not
seem to be charging.  I removed the dynamo from the engine and found that
due to oil and grime build-up, the brushes were frozen in the holders. 
While removing the small third-brush, I managed to break it.

So, a few questions:
1) Is there a US source for a set of brushes?  Any generic part numbers I
could even give to my local rebuild shop?
2) Should the unit be dismantled to clean?  Remove the crank gear?  Any
other tricks to opening the unit?  Or just leave alone and clean the brush
holders as best as possible?
3) Can the third brush be adjusted on the bench?  I needed to move it to
remove the brush but marked the original position.  Or just follow the
adjustment procedure once back on the car?

Thanks!
Jason.
