1.This is the Samsonite Essensis Pro Rolling Tote. I purchased it in April 2019 and use it for business trips about 120 days a year, so I've traveled around the country with it for nearly 600 days.

2.The main body is still in good condition and seems usable, but the wheels are starting to rattle and make unpleasant noises, so I decided to replace just the wheels.

3.This is a replacement wheel from a certain manufacturer that I purchased on Rakuten. Although the outside diameter is a little large at 80mm, I thought I could somehow install it, so I took the plunge and purchased it.

4.The box I received contained two wheels, two shafts, and U-nuts and washers. One side has a left-hand thread to prevent it from loosening when the wheel rotates. It also appears that the wheels are equipped with thin ball rings.

5.First, open the maintenance zipper on the inside of the bag so you can see the wheel mount.

6.Remove the three screws that secure the inner plastic cover.

7.This is the inner plastic cover that was removed.

8.The plastic cover that the wheels are attached to has been removed. It will come off easily if you twist it a little and pull it out.

9.There are holes like this in the main body, so if you go into a deep puddle on a rainy day, it will flood.

10.The tip of the wheel shaft is visible inside the cover.

11.Judging from this structure, it looks like the tip of the 8mm shaft is counterbore and caulked, so if you sand this down with a sander, the shaft will likely come out.

12.The disc sander is too big to fit, so attach a whetstone to the drill and scrape off the caulked part.

13.Sand until you can see the 8mm shaft. It was able to easily remove it by tapping the shaft part.

14.Disassembled wheel part and outer plastic cover.

15.The wheel shaft is 8mm and has a collar with an outer diameter of 12mm.

16.The part of the plastic cover that used to contain the collar has a 12mm counterbore.

17.The counterbore part is 12mm in diameter x 8.5mm in depth. The protruding part of the wheel shaft collar is 12mm in diameter and 11mm in length. It's a perfect fit.

18.When I installed the wheel, the shaft seemed to be a little short, but I managed to reach the U-nut. I don't think the U-nut will loosen, but just to be sure, I'll put a little bit of superglue on it.

19.Check that the U-nut on the wheel shaft does not interfere with the inner cover. It seems like it can be assembled without any problems since there is very little interference.

20.Attach the outer cover, then attach the inner plastic cover with three screws to complete the replacement.

21.Follow the same procedure to replace the wheel on the other side. However, since the wheels on this side rotate to the left, a left-handed threaded shaft is used.

22.Full surface of the wheel. If I ever need to replace the wheels again, I think I can do it by removing only the inner cover without removing this outer cover.

The wheels fit like genuine products and I don't feel any discomfort at all.

The wheel diameter is about 5mm larger than the genuine product,
but it moves smoothly without hitting the cover.

1.Being a mechanical designer, I decided to see what kind of structure the old wheels had.

2.Remove the cover with the logo on the outside of the wheel, and the shaft will come out.

3.The wheel part is 3/8 inch with a stepped shaft, and the part that inserts into the outer cover is 8 mm.

4.There are no bearings in the wheels, and they appear to have wear-resistant collars. In any case, this part seems to have worn out and become rattling.
