just fyi the new company (SR Rotary Performance) still offers the kit, stumbled across it the other day searching for something else:

Yea, I've reached out to them regarding warranty on Pineapple parts, even though I purchased from Banzai. Neither of them would offer support despite Pineapple selling w/ Lifetime warranty. Please be aware, SRR will NOT warranty anything purchased prior to change of ownership.
- The original design used bearings which are only rated to ~16k RPM (which is common for 6302), and even with stock pulleys you will exceed this as you approach redline. So it's common for the bearings to fail as I've learned.
- Also, the clearance to the water neck is super tight also when installing or replacing a belt, so honestly I would recommend the FFE kit knowing what I do now...

Small update on mine, the coating started to peel (maybe from the heat of the turbo/manifold?), but otherwise still usable with new bearings for now until the coating chips from the bearing bore >
- NOTE: I found an SKF bearings rated for 19k RPM, but they are only available with non-contact steel seals, not rubber. So we will see how the lubricants hold up over time from both heat and contaminants.

 

What is the part number? I would be willing to try it out. I've replaced the bearing in mine a couple times already and it might be squealing again anyway, but I'd rather not swap to a different pulley altogether if I don't have to.

 

Found it.

I swapped the bearings in the pulley last Saturday with the higher speed bearings. I haven't run the car yet since I'm building a new engine harness, but I noticed it was ridiculously easy to push the bearings out and in. You can almost push them in by hand, and they move side to side just a bit when you shake the pulley. It feels like there's not even 1mm of play, but possibly .5mm? There's no way to measure because they won't fall out of the pulley (without the retaining ring), but they're definitely a bit loose. They're the same dimensions as the ones I pressed out too, and those were doing the same which made me think they were too worn but I had just pressed those in maybe a year or two ago and now I'm wondering if the pulley itself is too worn.

 

You can try filling the void with some rtv to act as "liquid jacket" of sorts. Just something to make up for the difference in the void. Any excess will just splooge out and then once it cures.... done and done

 

so the pineapple pulley is nickel plated I believe. That stuff will flake off when if it’s super close to the turbo and gets hot. It’s possible that when replacing bearings that coating on the inside of the bearing bore was too thin or maybe removed during pressing. 3m makes a product specifically to make up this gap, it’s called bearing retaining compound. They have a chart online to pick the right one for the size of the gap and the temperature range. That may be your best bet, but could make it difficult to replace bearings in the future.

let us know how you make out!

 

I think I used grease last time to ease installation, so I was wondering if that exacerbated the wear. But wouldn't RTV be too soft to make a difference when the belts are tightened down?

Oh I hadn't thought about that, that makes sense. Thanks! I might try that. I probably should since they'll just be clanking around inside the pulley if I don't lol.
