Hi All
what's the secret to a smooth RB6 gear diff? I've just built one and it's "grainy", you can basically feel the teeth working against each other... I've built my share of 8th scale gear diffs, but I have to say I'm not an expert in dinky plastic ones. I've used a bit of lithium grease at strategic locations (outdrive, ring, gears) everywhere where there's friction and/or a risk of leaking, I've considerably greased/oil the plastic seal, I haven't overfilled it, blah blah blah, the works, then AE's 3K oil.
And still the thing feels like crap (and it leaks)... Do these things need to break-in or what? I 8th you break them in for a couple of hours to loosen them up, but here it's worst, it really feels wrong...
Thanks
Paul
