pto 1977 B80

Sorry guys but I need input I have looked high and low for all the information

I could find on this subject rebuild diagrams or assembly diagrams for pto clutch.  

I have been looking for help for my 1977 B80 pto clutch .
Started to remove it to check for grease and found like others posted
 a spring, 2 washers, a thrust washer,  a shaft-pto , and a 7/16 stud
 laying inside of pto. but I looked at all the diagrams and can't find one like this shaft-pto .
from the b80 .the diagram says it should have room for 2 snap rings one out and one inside.
This one doesn't have a place for a snap ring on inside.it pulls right out with
very little effort there's no way it will hold that spring in it would push the pto shaft out pto-t  out. 

I did read a post by Rmaynard about taking all that stuff out and
adding a shaft-pto 102872 and 2 snap rings 936125.

just a few questions guys
will a pto from a 1977 c160 work on the b80.i removed the one on my 1974
c160 and it looks different then the b80 pto.

and does that 7/16 stud screw all the way into the crank tight.

the 1st and 2nd pictures are  the pto-shaft

maybe these will help.  This is an exploded view of the PTO config from the Toro website.  2nd pics is the part# lists....2 snap rings 

or...you can look it up at this website...TORO

Thank you daveoman1966 I did find that diagram and the part numbers as you posted. But did you ever see that type of pto-shaft ? There was a snap ring with the other parts in the pto stuck in the grease. There is no way that snap ring came off that pto-shaft. I do have a pto on a 1977 c160 k341.will it work on the b80? ? Thank you

The PTO from the C-160 should fit w/out mods and you'll probably need to swap over the clutch disc too.... Use the bearing race for the B-80 .
