What size are the diff balls used on an 870c

hello All,

I have an 870c that I'm rebuilding and I can't figure out what size diff balls I should use. I bought a package of 3mm, but those seem too small

Regards,
Roger

1/8th, same as rc10 6 gear. Think they even use the same diff rings too.

I think chrome steel are just fine, they will last a bit less but the first part to replace will be the rings anyway.
Bye :wink:

I’d like to rebuild my ball dIff. I am pretty sure the RC 10 came with 1/8 inch balls. Is there a modern replacement for these? I have a new set of rings. Thanks in advance.

I want to say it's 8 for 6 gear, and a dozen for stealth. 6 gear could have more if you used a kimbrough gear or one that has a ton of holes. but the original gear was 8 holes.

Yeah, I counted 8 on one of my 6 gear cars but don’t want to open the...

On my re re Im running a Dynamite Tazer 4000 kv motor.....
After my first two runs (on a beach parking lot) I noticed my car not wanting to move. I noticed the diff balls had melted into the spur gear. I was told I probably had the diff too loose....

Tightened up very tight will give you pretty much a locked up spool action. If the differential spun in the event that you nailed the throttle on a tight turn, you would get some limited diff action and probably generate heat. You are far better...

First post

I was reading the AE manual for thr Worlds RC10 & it makes a point of stating that only the Associated 3/32 carbide diff balls should be used & if replaced with a new set they should even be all from the same batch!

I just wondered how critical is...

Looking to build my SC10FT kits and I want to convert to hexes right away, is there a kit that has everything I need or do I need to piece together from associated part numbers? Also do you guys have a recommendation for diff balls? Stock, kit ones...

Last post

The front wheel bearings will work fine as long as there in good shape. The wheel nuts would be the same front to rear so if you have some spare rears you can just use those. Aluminum hexes are not absolutely necessary, but they are more secure. If...

I don't think the test results relate to RC diff balls as they were comparing Chromium Oxide versus Tungsten Carbide.
