Hi Everyone,

I ended up replacing the gear clamps with some from a parts RF deck I 
got from a list member.  Thanks Russ!  Now I'm reassembling the gear 
train following the gear rebuild document on the R-390A.net website. The 
steps for re-installing the final differential gear don't seem right 
though. I don't see an easy way to load the split gears on the 2-4 Mhz 
slug rack which mates with the rear gear on the final differential gear 
if one has the 1-2 Mhz gear installed. It looks like it's going to be 
hard enough to load them even without the 1-2 Mhz gear installed.  But, 
the gear rebuild instructions do not mention loading the 2-4 Mhz split 
gear though. Any tips on re-installing the final differential gear?

Thanks
