Dickyho 5M 36T / 40T flywheel pulleys on ebay

Ok I got it sorted out for TB218s, 4 speed washers on the inside, 1 608 bearing in the pulley, this still leaves plenty of axel for the wheel nut. I don’t want to run it right at the edge of the nut that’s too risky for my liking. With one bearing it still runs nice and true. And there is enough space to not have the belt touch the wheel. :grinning:

You do need to file the truck down some though.

Hi. every one. after consider, I decide to keep all wheel pulleys stick with the old design with 22mm bore. because 25mm bore will not work with this design.

there’s a 10mm thick 608 bearing (not remembering what it model name), can install like this way.

You are welcome… they are hard to find… on AliExpress they call them 608/10ZZ if you are more fancy ordering there.

Good decision. I found that temporarily installing a 608 bearing keeps the pulley centered while I tighten the retaining bolts. The idea of using a 10mm thick bearing means the pulley not only self-centers, but also now redistributes some of the driving forces. Nice!

what is the upside of having the bearing be connected to both the inner core of the wheel and the pulley? does it transfer more energy or is it more efficient?

81

I’m hoping it eliminates/reduces bearing creak under hard acceleration (esp. on a single motor setup).

i bought my bearings for 30cents, made for industrial use and not from the skateshop, no problems so far. they come with grease not oil and i think that is much better

83

Would be cool if you could get a bulk order of these and include one with each 40t pulley

The zz means a metal shield I think, 2rs (rubber shields fare better)

Bit the bullet and bought these pulleys yesterday (40T 17mm). Bought 15T 15mm as well due to the low price. However what i really need is 5T 15mm steel pulleys with keyway!
