Hi, I have problem with bleeding the bearing of my gearbox (M32 gearbox). I putted a new one and in the bleeding procession, it broke and spilled all the brake fluid from the inside of the throw out bearing. I want to ask you how to make a correct bleeding. (My new throw out bearing: 510018010-LUK )

Good morning,

Did you already replace the throw out bearing?

Hi.

Thank you Roy for your reply (and sorry for my bad English). Yes, I replaced it but I broke it when I was trying to do the bleeding (the clutch petal stayed down and from the bottom of the gearbox was dripping brake fluid). I will buy another one tomorrow and I want to know how to install it correctly without damaging it.

I am concerned about why the new one broke. How did it break? It should slide on the nose of the transmission and just seat when the transmission links to the engine.

As far as bleeding, let it gravity bleed first with new fluid in the clutch master. Once the air is gone, you will need to do some pressure bleeding to get the rest of the air out of the system.

I think I didn't explain well my problem. It didn't break any visible part from the throw out bearing, it seems that the seal inside (o-ring) failed and leaking, now when I add fluid I see it coming out from the interior of the throw out bearing. I think in the bleeding process some air left inside which caused, the seal in the interior of the throw out bearing, to fail.

Roy, thank you very much for your patience.
