K100 1985 tiny bearings bottom of the clutch case area Bearin11
I am working with a K100 and when I was installing the transmission observed small tiny bearings, have inspect all parts around and haven't see from where they are.
Have some photos available if needed.

K100 1985 tiny bearings bottom of the clutch case area 177912  Pictures would help, there are two needle roller bearings situated on the clutch lever arm pivot pin. While your there fitting a grease nipple to the arm is a good option.
Regards Martin.

You need one more post first (five in total) before you can upload pictures. This rule is to slow down spambots.

Saludos Laitch, aproximadamente 50 de ellas, tengo fotos disponible, no se cuantos comentarios tengo que realizar para postearla. Son bien pequeñas, como la cabeza de un alfiler.

No hay rodamientos en el paquete de embrague. Are you sure these are not fine metal particles en vez de bolas? We need photographs, so keep posting until you can submit some. Laughing

Is something strange, I hope someone knows where they come from, I don't want to install the transmission with a dough.

They look like droppings from a robo-mouse. Are they magnetic? They wouldn't bother me; I'd toss them out and move on. If more appeared I'd set out some traps. Laughing

It looks like a bracelet that's been dropped in the housing when the clutch was off. The clutch then proceeded to dismantle the bracelet. As Laitch says, there's nothing like that anywhere in the engine.

Could those be balls from the throwout bearing?

Don't worry about them, they form from wear debris and are rolled into the spherical form by the rotation of the clutch. You'll also see carbon balls form in starter motors from worn brush material.

The old-style throwout bearing balls are gigantic by comparison and there are only 10 of them.

They were not there when I took of the clutch, when I instal the gear box, pressure plate went out of position, and when remove the gear box saw this small bearings. I inspect the pressure plate, can see where bearings can be part of the pressure plate.

They are most likely bits of debris altered as Martin described in Reply #16. They are not bearings. The pressure plate does not have bearings. They might be bits of metal fallen from the pressure plate. Post a photo of the pressure plate area where you believe this debris was attached. Your photos are good quality.
