i use a long twist tie wire, from a bulk foods bag... remove the paper from the wire, wrap the pawls down, twist ONCE...... get the pawls started back in place, untwist wire, then remove the wire.
old copper single strand telecom wire with the insulation removed works great too.

you could use old school dental floss too.. tie the pawls down with the floss..., start them into the hub, then burn thru the floss with a lighter or match.

a few decades of re-assembling alternators and electric motors, with New armature Brushes, teaches you lots of tricks like that.. scotch tape, strips of shim material acting as a "funnel" to help guide the brushes or armatures in place, etc, etc.

ATV/small engine pull starter springs... those twist ties work magic in that case... plus lots of practice, and really careful finger work.
some come pre-tied to ease installations.
