The R9's are the same mechanically as far as operation. If you are referring to the "balk ring" then it is present.

In looking at the Econodrive servicmans training booklet (1946 version downloaded from site) instructions, there are a couple of things mentioned. When you installed the solenoid, did you energize it by grounding the governor wire (pg 13) so the stem was all the way out before engaging in pawl? Also, there is a caution on pg 18 about solenoid orientation as a reason for not engaging.

There is an article in Service Counselor Vol21,#14 pg 69 re engagement if the balk ring is worn & has insufficient friction. Only mentioned in passing since you had a working unit.
