Do you get dial tone if you turn the dial? If so, it may be that the dial is wired back-to-front so that the pulsing contacts and dial-off-normal contacts are transposed.

Failing this, do you get dial tone if you move the red wire of the line cord from T3 to T4, thus bypassing the dial? Clearly you won't be able to dial with this wiring.

If neither of these restores dial tone, I can't see why eliminating the bellset (which may have been shorting the dial via T9) has stopped you getting dial tone.
