How much roller grease?

Finally got a grease pump and bucket of Chevron 00 grease.
Sweet D2 sat in a shop for the last 30 years with a broken block and I'm sure it wasn't maintained.
I put 8 pumps slowly into the rollers and 10 into the trunion (?) fitting with none squirting out and no apparent increase in pumping difficulty.
So, my question is, how can I tell when the rollers have received enough grease?
thx

I would think that that number of pumps should be sufficient to lubricate those parts,
Perhaps run it some and see if any grease appears??
