In regards to ball bearings.

I've recently changed the standard SD bearings to the Silver Squat ones. The wheel bearings were all stuffed up on the standard ones.

I feel the squat ones need a clean soon. Every time I pull the wheel bearings apart (Shields) and apply motorspray, I can't seem to get the gritty feeling away. Is it possible to remove that gritty feeling? or are the bearings just shoot?



Thanks

Not long ago someone posted that they completely tore down the bearing, and took all of the balls out, said that they got all of the grit feeling out of the bearing, and it spun better than new. I feel like that's a lot more work than I want to do on a single bearing though...

Delrin diff halves are very delicate. The stock Yokomo plastic ones will be more resistant to bashing.

Remember the delrin diffs on the old YR4 variants? We were snapping them constantly, and that was with the sort of power we had some years ago.

With locked front diffs, more traction from modern tyres and more powerful cells and motors I can't see a delrin diff hold up for long.

Randman.

How do you get on with the delrin diffs on the Barracuda, running hot mod motors?

I've never had problems with diff outs in the past, besides normal wear. To be fair, I never owned/raced the YR4.

I'll be sticking with the stock diff outs now that I've got them working with blades - but harder delrin items are tempting - just so long as they aren't fragile like you say. I've had enough durability issues with the Yok as it is!!

Out of interest, I broke my first H version c carrier. The breakage occured midway through a race that I was leading against an ex Schumacher driver. I didn't crash, but I was continually riding some 'curbs' on a left - right section. Looking at the cross section where it broke, there appeared to be a flaw - it looked like a bubble (or an area of NO material whatsoever) right at the bottom of the C. Godammit! Why does it always have to happen to me?

Now this is stupid, you can't take the balls out of a bearing with the usual tools. Besides, the ball spacers are sometimes crimped, which means you'll have to destroy it to take the balls apart.

I don't know who was this guy but don't trust him...

The best way to get the grit out of bearings is still to get hold on an ultra wave cleaning device, or know someone who have one...

Interesting. Might have to give it a try!
I remember a similiar product being used for cleaning jewellery years ago!

How does it compare to a bearing blaster?

Ultra wave cleaning device - sounds too cool to pass up - no one I know has one, so I'll have to track one down.....

Is this the one you mean?

Looks like you add motor cleaner, then it 'vibrates'. Probably has a small electric motor with off-centre weight - like those found in PS2 Dual Shock Controllers.

.....amongst other things........

yes exactly, this is the device, what do you think about that?

i think it's acheaper possibility than a "original" small parts cleaner.

I think it's a really good idea. I suppose it must work too otherwise speedtech wouldn't sell it. And it's pretty cheap.

Surely, it's got to be less hassle than blasting them clean with compressed air, motor cleaner followed by more compressed air or whatever your routine is.

I'm going to try and get hold of one.

Do you know anyone that has one already?

Yep, I sure will - I'd waffle on about just about anything
