Servicing Mini-Z MR-03

[@CK4RT_4B-4B0]

When servicing or doing a maintenance check on an mr03 ball diff, what ball diff grease would you recommend?

[@sammybaka]

I've been using some MST ball diff grease, but any ball diff grease would do. Ball diff grease is thick and sticky to help with contact adhesion between the balls and diff plates.

@@sammybaka thatnk you very much, was a bit worried when looking at the options for ball diff grease as it might be too thick.

When you close the spur gear, how tight it supposed to be? I have a RX28 diff and i set it tight because if i don’t it will get loose and the shaft will spin

[@sammybaka]

I try to run my diff as loose as possible but without slipping (e.g: as not to damage the balls or pressure plates). For larger tracks with large flowing corners, I might stiffen the ball diff.

Ciao, dove la posso acquistare?

[@sammybaka]

I bought the generic diff balls here: www.aliexpress.us/item/3256805105303049.html (I picked the 2.381mm)

Do you have to do this?

[@sammybaka]

After a few sessions on a track, I'd consider serving a ball diff like this because dust and stuff start getting in between the plates. Balls should last pretty long unless the diff ran too loosely.
