:bigsmile:Ok here it is I have been cleaning the woofers for about 2 hours... One thing that worries me is they say to remove the dust cap and use shims but these woofers it looks impossible to do because the dust caps are flat ..

Should I try to get the dust covers off are just take a chance and put the surrounds on and be real careful ??? The cover for this that is not pictured is in mint shape as well so if the speakers turn out a little ugly you will not be able to tell ... The woofers are 4 ohms and they were wired in series then too a crossover and the Ferrofluid Cooled Polycell tweeter is in mint shape ... I am really worried about trying to get the dust caps off??? Do I have too shim it and take the dust caps off ?

I've never done a re-surround, but seems to me that shimming would center the voice coil and thus enable the re-surround most accurately. Otherwise, if you glue the surround to the cone first, let dry, then apply the glue to the frame, followed by pushing the surround into the wet glue while the driver is perfectly level, it seems that would be a good method.

Perhaps someone else has done this successfully?:help:

Well I decided to remove the dust cover .. it was a slow process but probably well worth it .. I used a little thinner and rubbing alchol and a razor blade .. Took me about an hour to get this one off ..

After removing both dust caps , I really see the need to shim before putting on the new surround because with out the surround the coil moves everywhere.. And if you are off one MM of an inch you will have to start all over .. so now I am going to shop for the new surround .. I think I am going to go with a woofer rubber surround instead of the cheap foam that was on it originally... More to come

Sorry I missed this thread. I could have saved you some time. I have done many of these and found that rather than removing the dust cap, I can get more perfect centering by leaving it, and not risk getting dust and debris in the gap. What I do is use a slow drying glue (my favorite is WelBond) and start by gluing the surround to the cone. The slow drying lets me get the centering as even as possible. Once that dries, if you put a weight on the cone (use a smaller speaker) to push it down slightly, it lifts the outer edge of the surround off of the basket, allowing a bead of glue to be run along the inner edge of the basket under the surround. Then release the weight and let the cone rise up. The coil will be very close to centered in the gap if you are careful to place the weight inthe center because of the tension from the spider. Tamp down the outer edge, then as the glue is drying you can move the cone up and down to verify that there is no scraping of the coil on the poles. The slow drying glue lets you center it if needed.

The problem with shimming the gap is that you can get some uneven surrounds or pulling due to glue drying, and still get an off center job. You also have to be very careful not to get dust in the gap.

OOPs .. I guess if they screw up I could get some Dayton's and throw in there but i am tring to keep it all orginal .. I guess i Could glue the caps back on .. and I have a couple of old cv tweets I could set in the center of the speakers for weight ... I may try the shims .. my biggest problem with these 902-6416 speakers is that they are 4 ohm and hooked in series in the cabinet.. It is a center channel infinity .. And it is hard to find good 5.25 inch 4 ohm home speaker replacements.. Since I have already got the dust caps off should I shim it or just put the caps back on and try it with weight and slow drying glue..?

If you already have the caps off, just go ahead and shim it. It is the easiest way to do it.

For the surrounds themselves or for the service to replace them?

The surrounds are tough, unless you want to pay $20+ for the kits. I have gotten them from MAT and from a handfull of others that have them intermittently, but currently have no good suppliers for you other than recommending the folks who repair them. Some will sell them separately as parts, some will not. The main supplier that most use only sells to speaker repair shops and will not sell retail.

Look in the thread here for speaker repair shops:

Thanks Robert I may have to do this .. This will be my first .. And if I mess it up I can probably find some good 5.25's somewhere.. I was just wanting to use the orig. because that is what the enclosure was built for..
