Gear diff building issues

[dobber]

Right, just building the sc gear diff. No instructions but it's quite self explanatory. Put it all together, filled it up with oil and tightened it up but when it's do e up the diff is not free running at all. I have to back off the screws about half a turn then it frees up but the there is a slight leak of oil from where the screws are. Any advice most welcome.

Take some of the oil out, it sounds like you have over filled it and the gears have no room to move.

If it dosent help with less oil, you can use two gear diff case seals.
But this will not work in a Vega gearbox because the diff will get to wide.
