Topcat/Cougar Thrust Bearing
I thought I read Losi ones will work, one on left is Schumacher and 8mm across, all the Losi ones I have are like the one on the right and 10mm. Anybody know of something that is the 8mm size?
Re: Topcat/Cougar Thrust Bearing
It must be the XX thrust bearing that works. It is smaller than the LRM one.

Re: Topcat/Cougar Thrust Bearing
The only thrust bearings I used BITD were the Losi units. The one you have there must be a later unit. -Jeff
Re: Topcat/Cougar Thrust Bearing
Now that you mention it I do remember the TB being smaller on the LRM. Is the larger one the heavy duty?

Re: Topcat/Cougar Thrust Bearing
450 trex helis (and clones) use similar sized thrust bearings in their blade grips. They have a pressed cage that keeps the little balls captive.
I haven't tried them yet, but have a feeling they may come close to fitting the diffs of our old schueys.

Re: Topcat/Cougar Thrust Bearing
3x8x3.5mm thrust races are readily available from eBay but because the Procat axles are 1/8 inch (about 3.2mm) only one of the thrust plates will fit. I had to buy two bearings to make one. Is this also the case with the Topcat axle?

Re: Topcat/Cougar Thrust Bearing
You are right, that thrust is all over the place, I am not sure I follow what you are saying about the axles though. The factory set up does have two washers and in addition I have read the back threads about using 3 belleville (cone shaped) washers as well.
Re: Topcat/Cougar Thrust Bearing
The bearing comes with two thrust plates, one with i.d. 3mm and one about 3.2mm. Only one of these will fit over the 1/8 diameter axle hence you need to buy two bearings. That's what I found anyway. If you find a proper 1/8 bearing with two larger plates let me know ![Very Happy :D](./images/smilies/icon_biggrin.gif)
Yep, don't forget the disc springs either
for some reason Schumacher left these out of some manuals e.g. Bosscat.

Re: Topcat/Cougar Thrust Bearing
Ahh, just realised we may not be talking about the same thing. Mine's a Procat Axle/thrust assembly. The T-Rex450 jobbie fits this. Apologies if I mislead ya's
