TO 9H2-4-44-23 is the one we use : it says you got to drill the hole , but not the dimensions !
The P/N of the elevator booster is 374461-5 and the shaft 363497-1 .
We've looked allso in LIBVIEW , but there we didn't find either dimensions !
It's even a bit funny , because in libview you find the complete dimensions to drill the hole for the sector assy on the same shaft , and here you can't make any mistakes !
thanks for your help
