Carb diaphram removal

[petejw]

Start by cutting the top ring with a very sharp knife,
place a screwdriver in the cut and carefuly pry the top ring off. To replace, i sprayed the diahpram with some silicon spray and carefully put the upper ring back on, the lower ring has a recess and the bottom of the diaphram must sit in this recess to seal properly, carefully pull on the diaphram till you feel the diaphram seat in the lower ring recess.





Because the diaphram is a pressed fit youll need to tap the upper ring lightly for a secure fit being careful not to damage the diaphram.









all done. :-)

Well done, Pete. We'll want to copy that over to one of the permanent tech tips lists.

just read my above post and noticed i didnt give credit
where credit was due,
i didnt come up with this idea,
i copied it from Mathh from the uk site, thanx mathh.

Pete, I'm not quite clear on the cutting of the top ring. Do you reuse the ring that you cut?

[Toolmaker Tim]

Reusing top ring

Ok, I looked closer and I see what was done now. The cut doesn't affect the ability of the ring to lock the diaphragm in place,correct?

[petejw]

hi tim,

yep thats correct, u can reuse the top ring, i never glued
the base or the ring imo it wasnt needed and the diaphram
is secure.
if u do cut the top ring and plan on using the diaphram below it,
just be real careful as it isnt to hard to cut the diaphram with the knife,
if ur replacing the diaphram then this wouldnt matter.

Very cool Pete. Thank you for passing on the process!

[petejw]

no worries Tim.

If you go here and scroll down the page this guy has a good looking process going as well.

one other thing that i didnt make a note of at the time
is making sure the hole in the slide is pointing to the front of the carbs
when the "tab" for a better word of the diaphram is seated in its spot.
in the above pics i havent done that, but have since.

[Toolmaker Tim]

Well now that I know how easy it is,maybe I should put my spares up for sale. Maybe I can help someone out there that needs a set. They are getting hard to find.

hi ras,
i saw that when i bought my diaphrams a while back,
i tried it that way using
the old diaphram to remove it, i didnt like it.
cutting the top ring was
a much better and safer way of doing it without the worry
of ruining the new diaphram.

I was just trying to show that there are a few different ways of doing it. Many have preferences of one way over another. I have never tried it yet but have some to be doing so I am looking around for my best option. I forget where I got the pic I posted in the other thread but it was from a supplier and it showed the way they recommended doing it. Just the pic and no instructions. So if you or anyone else has had experience, I am listening

[petejw]

i wasnt havent a go at u ras for posting it,
just stating that i tried it that way and
it wasnt a very good method compared to cutting the
top ring.

No I realize you were not having a go at me. I am all ears here learning new stuff. I was pleased to see your posts and every thing I find out will make my life easier when I do mine.
