Should there be oil in there?....

[Nemo]

I have an '03 Suzuki GX 125, wish is pretty identical to the GS 125.

Basically the starter motor has packed up, well, it makes the noise but doesn't turn anything (best I can describe it).
My mate thought it might just be carbon brushes or something silly and has a spare one I can have any way.

Went to take it out, but it's not as simple as pull it out, so start to unbolt the casing where the generator magnito thing sits, and oil starts dripping out.

Just wondering why or how there would be oil in there. If the seal has gone, would I have to take out the whole engine and strip it just to change that seal?

You should be able to unbolt the magneto plate and remove it and see the oil seal beneath, a careful hand should be able to drill a small hole in it without damaging the area that the seal runs on.
Next you screw a small self tapping screw into the oil seal and yank the bugger out with pliers, 2 opposite screws may be required.... Install a new one with a suitably sized deep socket (to drive it on the outer rim) then build it all back up and jobs a good-un

Is this engine similar to the CG125? From what you describe it sounds similar and I know exactly what you mean because I panicked when I first saw oil around the magnito. If I remember right the cover is quite tight as its magnetised and the oil is fed through a small hole under the magnito. Its the same on all the Chinese CG derived engines (FM series) too.
I've taken a few of these engines to bits and they all have the same feature, oil in the magnito housing.

So it's nothing to worry about?

I need to somehow get the starter motor out and it's not as simple as "tug" it out (I was hoping it would be).

So I don't know whether taking this casing off would help.

Would this mean that I will have to drain the oil out to do it?

Thanks for the advice, put my mind at rest, sounds depressing but never had a 4-stroke before

As said I don't think you need to worry about a bit of oil dripping out, but are you sure you need to be taking the engine casing off? Isn't the starter motor just bolted onto the front?

Also are you sure the starter motor is your problem? Does it bump start?

Lol I'm said friend.

The starter is held on by 2 bolts on one side and the actual end of the starter is hidden near the magneto/flywheel.

I started taking the engine casing off on the magneto side and oil started running out.. So I tightened it back up.

Probably check it at weekend, but it's not broken atm...

Also nemo, engine doesn't look like the gs one. Look at the en125 engine

Hi,

Its normal for quite a lot of oil to come out as the drain hole is quite low down on the engine. I ended up draining all of the oil out

If its the same as GS no need to take flywheel cover off just 2 bolts & cable to remove .
