On my 1993 bullet one of the timing cover screws doesn't have a wavy washer but a fiber one. I've high-lighted it in the picture.
I have a full gasket set but there isn't one small enough in the kit. Is it correct that you use a fiber washer in this location?



Also item 7, the drain feed plug aluminium washer; There are aluminium washers in the gasket set but none even close to the right size.

Number 7 is the washer for the quill feed (item 6) which is in the bigger hole to the left of the one marked. The set screw in the hole you marked should surely have a copper washer as should all the others holding the case on. Mine certainly doesn't have "wavy" washers - has someone in the past put some form of spring washers where the original copper ones belong?

[p]

Oh, sorry, the diagram you show has 10 spring washers listed - maybe that's correct then - it seems different years list singly or in combination copper,fibre or spring for the retaining screws perhaps this one screw uses fibre to avoid seepage as this particular screw doesn't go through the peripheral gasket?

[Revband]

The parts list shown clearly says "spring washers" the earlier bikes had gasket paper washers perhaps someone has used one of these to stop a leak?.

[p]

Oh yes it does.... think I'll turn in for the night!

I'll scrap the small fibre washer where I high lighted then, and order some more crinke ones (I'm not keen on spring washers). The one there at the moment is a real thick orange fibre one, but now totally warn out. The aluminium one I'll re-use.

A spring washer will not provide an oil tight seal. From memory (and it ain’t that good some days) it needs a fibre or soft aluminium washer because the shaft of that bolt is in constant contact with oil, although it’s not exactly a major job to swap it out when it leaks.

I've come across a more modern parts drawing.
In this one item 6 is a fibre washer and item 30 a copper washer. Go figure.
