87 venture royale diaphrams

Hi, is there a trick to re installing diaphrams? I put them back together but they keep blowing apart. The plastic washers and metal sleeve are all in peices everytime I open cover

You can try to put some glue in the joint area, but that doesn't always work either and then they are screwed.

You can also try to get the diaphragms that have a rubber boot that holds them on, but if your slides come apart it doubtful that will help either.

My guess is that the plastic is cracked and therefore the 2 parts won't hold together, so time for new slides. Cracks are very hard to see or find, but logic tells me that something got larger or weaker, and it wouldn't likely be the metal part.

I have heard of some have some success with crazy or super glue but for the most part my experience has followed along the same lines as what Marcarl mentions.

Thanks guys, I was thinking about glue myself but wasnt sure its a good idea, now I feel i have nothing to lose and will hopefully be able to source new slides if all else fails

You might be able to use these with your existing sliders. I have not used them but I believe others here have.

I have used them several times and they work great. But the stainless metal piece still have to be secure in the plastic slider even with JBM's  diaphragms.

Here is a note from JBM's web site with regards to the sliders:

Yamaha Venture Notes:  The 73 mm Mikuni Diaphragm fits the Venture models even with plastic slides.
Remove the short metal tube from the plastic slide if loose, and remove the rings. Place the JBM Industries
diaphragm on the metal tube, and then push tube into the plastic slide. Use Super Glue on metal tube. If metal
insert tube is not loose, just cut the rings off plastic slide with side cutters as shown.
