Spare circlip and washer after assembly

Enter a word or two to search the forum section and click the Search Forum button.

Classic school boy error. I have reassembled my Webb 14" 1960 style mower but have a circlip and thin flat washer left over. They were on the bench together and are the same diameter suggesting they go together. The shaft diameter would have been 5/8" and they are quite clean so I think they must have come from the clutch/drive assembly.

Does anyone have the exploded view of the clutch arrangement?

I'll be more careful next time and take more photos.

2nd concern.... Should the nuts on the roller shaft be left loose? When I tighten them up the roller stops turning, not surprising as it is a solid connection to the roller. The nuts appear to just be one half nut which seems quite out of keeping with the way the rest of the unit is engineered. Am I missing something here (besides the circlip). Nowadays we would use a nyloc nut.

I found where the circlip went hidden under a surplus of grease I put on.

Would still be interested in any comments on the roller shaft nuts.

Good that you've found a home for the circlip and thrust washer - parts 6 and 8 on the "alternative parts .....  illustration?

Back in the day it was not unknown for the workshop joker to leave a few "leftover parts" on the bench where they would not be found until assembly was nearly complete. Today it would probably be classed as bullying or harassment!

Roller (rear?)  should be free to turn on its "dead (stationary) shaft" No1 in the illustration. If it binds when the shaft is tightened it is suggesting that something is not assembled correctly  - the shaft should be tight.

(I know that the captions say 14" but the 18" was just a stretched version  and my 14" book has better illustrations.)

Thanks for the assembly which makes everything clear.

The shaft in the roller was so firmly stuck that I just assumed it was welded or a press fit. Looks like I will be taking the non-drive panel off again to work some magic on the shaft. I don't really mind. As far as learning experiences go this was quite painless, almost fun. 

I think the next one will be more of a challenge. I go to pick up an Atco standard NY tomorrow with the Villiers engine. It looks like everything is there except the starting handle and grass box. I guess with the older machines that getting spares is nearly impossible so I will need to be really careful not to damage anything during disassembly. Fortunately I work for a Gasket cutting firm so getting replacement gaskets should be ok provided I can measure up the old gaskets.

Thanks for the help.

My mistake HY. That's the very one. I'm going to start a new post on the subject as I have some questions.
