Kayfun [Lite] 2019 (22mm) Design Change (?)

[Hobbs]

Ref: Authentic kayfun [Lite] 2019 (22mm) s/n 007651

Removed the deck from the 510 connector base and found a nylon bushing on/around the center pin and fitted into the base. I had expected to find an o-ring instead. There is no o-ring, just the bushing.

Every picture, every video, every diagram of the KFL19 I can find, only shows an o-ring and I've not seen mention of a bushing nor availability as a spare/repair part. Furthermore, I've not found any announcement of a design change.

Incidentally, I've not had any leaks from the 510 connection and am just a bit puzzled by what I've found but expected to find.

The atomizer was purchased recently from CDV. The parts diagram below, is from the svoemesto website and shows an o-ring (item 4) but no bushing.

Comments and personal observations appreciated. Thanks !!!

Yes, Hobbs. SVM changed the design with batch 2 as you illustrate. The diagram is the original design from batch 1. They also got new capture screws beginning with batch 2. The batch 1 screws were a bit wiggy and would be a little hard to turn in. Turned out to be defective screws from their supplier.

Thanks Bronze. I couldn't find any mention of the o-ring to bushing change anywhere.

One coil leg capture screw was fine, but for the other, I still had to cherry pick through accompanying spares for a coil leg capture screw that wasn't hard to turn.

Hmmm. They claimed they ran into some bad screws and got it corrected with batch 2. Doesn't appear to be the case based on your experience. It wasn't a show stopper as the fix was to go ahead and ram it thru. It would self-fix itself. But it's a little scary to ram through a screw. Especially on an expensive atty.

The one I had a hard time turning was on the deck positive block (item 11 in the diagram). I didn't do any swapping around to determine if it was a screw issue or block threading issue. Regardless, got it sorted and haven't looked back.

EDIT: Honestly I can't remember for 100% sure which threaded hole in the deck it was that the screw was hard to turn. All good now anyway.
