You can't the bearing is dead. You need to go and buy a new thrust bearing available at most good bearing stores, or hobby shops. To prevent this from happening make sure you lube the thrust bearing before each race day with a good quality high tempature grease like moly grease.

the best way to maintain the trust bearing is to set your clutch properly. I havent lube the trust bearing long time and they work fine. I only lube them once ever 2 week "at most" or when I remember !

Well that may be your method but I wont start a race day without first lubing the thrust bearing. Each to their own I guess. I also pull my car and motors down after every run to check them over, so I just do the thrust bearing as I'm reassembling the clutch.

surely agree but your trust bearing will possibly dry up in the first lap no matter how much lube you put on it unless you are running a snake closed trust bearing device !

as i said, a proper setup clutch is the insurance of your trust bearing from failure. the failure of the trust bearing is mainly due to over rev of the clutch bell from clutch shoe slipping

I agree with Manticore. I never lube my thrust bearings, the only time they failed was when i stuff the clutch settings up.

having the clutch shimed properly is a given. but if run
dry it will give out at the most unexpected time. like during
a race.

I think if a trust bearing is going to go it will go. Its more important to check your bearing cage for wear. having lube on the bearing gives more chance to something sticking to it.

Manti, what lube do you use. I use Mugen 'Sticky' grease, after a full days racing, there is still grease inside the cage.

Funny story was back when I first starting running the original MTX2, our supplier didn't have any grease at the time, so I'd lube up the thrust with heaps and heaps of Tamiya grease (the white stuff). The second I tried starting the car on the starter box, the grease would hit me in the face.

If any bearing is going to go, its either your clutch or thrust bearing. Don't forget these things spin at 35,000+RPM and take alot of the crankshaft heat. Setup up correctly, heaps of grease, and thats one less thing that won't go wrong.

For the thrust bearing, I used to lube it with some light oil. I'm getting lazy on this and only lube it if I remember. However, I will blow it with compress air almost every time I clean my car. The bearing is still in good shape.

The thrust bearing is not design to spin at a very high speed. Indeed if the clutch is not slipping severely, the bearing only rotate almost near the engine idle speed.

I will only use ronnie gease for this trust bearing if I want to.

well, wolf is correct, the trust bearing only spin before the bell is engaged. so again, if you set up your clutch correctly, the chance of toast up the bearing is very low. besides, even the snake has enclosed trust bearing, people are still toasting the bearing because of incorrect setup of clutch.
