Hi,

Does anybody know where a small M3 type black washer would fit in the alloy assembly that slides back and pops up once the leaver has been fully extended?

I've fully service two 601's now and each time I've removed this sliding part, removed the old seal and washed the whole assembly in parts cleaner, I ended up with one small black washer from this assembly in the wash pot. All I can assume is it lives under the transfer port seal to add thickness?

Both guns I've serviced perform 100% perfectly after the service with out this washed fitted back on the gun, and are very consistent over the chrono. So I can't see that the washer is particularly needed? I have tried putting it under the transfer port seal in the past, but it makes the seal way too tight, so it can't live there I assume!

I just want to say the guns are working perfectly, so I've not left any guns in a dangerous state, but it is a bit of a mystery to me.

Thanks for any pointers.
