Anyone having Savage diff problems?

You can simple machine the ringgear down to 8mm od instead of the usual 10, that removes one weak bearing. the 16X8X5 hold up fine.

hi

those cen diffs look nice for sure.


the 'old school' usual mods i and many others did to the savage diffs were the following.

- use a kyosho IF103 cup instead of the normal 'plastic' cup. so you can mount a 16x8x5mm bearing there.



- trim the ringgear so you can use a 16x8x5mm bearing there too. like serum said above.



- inside the cup trim the pins down a bit and use the little plates (here shown in a alu cup). works well in the plastic cup.



four years later hpi did the same principle to their 'new' savage x diffs.



- to take the stress from the inner bearings you can mount two additional bearings 21x12x5mm on the diff




- trim the bulks






diffs modded like this and shimmed properly hold up pretty good. of course all of this can be done the alu parts (cup, bulk etc).
i know this is all very old news but it fits to the topic here. maybe some 'new' the savage stuff havn't seen this before.

bye

Ring gear is hardened and the carbide bits cost more than I want to spend. I don't need/use carbide bits in the gunsmithing I do (competitve rifles mostly), the metal I work is not that hard. If I had carbide tooling, I would've have tried it already - I know of a few from Sav Central who've done it and it seems to fix the prob.
