XRAY - Model racing cars

Pls let me know if anyone ve same problem
I build my x12 diff according to the instructions manual but it slips and not smooth at all.
I replaces the trust bearing unit to a b bearing and it works better........

Hey,

sorry to hear about your problem. I have some questions.

are you using standard spur gear?

Have you sanded the diff plates flat?

Which grease do you use?

Regards
Olly

Hey,

I use 800 wet n dry. Your grease should be fine

Hi Olly

I use AE grease, kawada spur, and I didn't sand the plate.

Tks

Hey,

Please try build with standard spur gear to see if problem goes away.

To get a smoother diff try sanding the diff plates on a piece of 800 wet n dry. Fit the plate to one of the diff hubs then sand in a circular motion. Make sure the sand paper is on top of your set up board so its on a nice flat surface.

Hope this helps.

Thanks for the advice

I will try all and let you know
Unfortunately X-ray spurs are not easy to find here.......

Cheers
