heavy 10 star knob clutch assembly

Nathan Baynes
 

hello all,
I am wondering if a 1942 era single tumbler heavy 10 has a thrust bearing in the powerfeed worm gear and clutch assembly? The lever operated era seams to have this but when i tore mine down (star knob)for rebuilding, i found no such thrust bearing?? also my spring inthe clutch spline washer stack has been eaten up. i wonder if anybody has specs on this spring or a spare one?? thanks in advance for any answers or help!
