Hobbyking wheel pulley retainer UK

Has anyone got a spare retainer + bolts for the Hobbyking wheel pulley? I bought the pulley set not realising there was no retainer included and the retainer rings are out of stock :frowning:

You could supplement the ring with a large washer and drill the holes out and just get away with is and buy when they are in stock. I was running my first month or two like this because of similar issue.

Thanks for the tip, I’ll try it when I get back to my tools. Cable ties are holding it for now :slight_smile:


Did you ever get some or find a replacement? Just realised this after iv ordered 2 sets! Still on backorder for the retainer rings!

Mine is still held on with cable ties! I haven’t ridden it much though, maybe 20km, my X car beast had purple light of death and haven’t got around to buying anything new

There is a 3d print file on thingiverse that fits. If you can’t find them or print them I can help you out. Those wheel pulleys are something like 25mm wide.

Hi Ben,

I said I’ll print them :slight_smile:

We have found a file thingiverse but it sounds like you have already printed a retainer before. Which one did you use?

Cheers for the offer Ben like @moon said he’s kindly offered to print me some…this is the file I found

and iv ordered some 2" hardware,bolts that @squishy654 said fit so should be all good,been a while since iv been out on my board,drv error that I’m having fixed on my focbox by @Martinsp…looking foward getting back carvin this summer!!

No, that’s not the one. It needs 4 bolts. I’ll dig it out.

Yeah if you could link the one you found we’ll have a look.

Nice one,was just gonna use 4 holes and leave the other 2 but if you have the exact one needed even Better!

I have the file but don’t seem to be able to find it on thingiverse.

Something like this.

Actually yeah think that looks the closest ben,this is the part were trying to replicate.

It would be much easier to go to your hardware store and buy a 45mm od washer and drill the holes in it. That’s what I have done on both my boards and it has worked like a charm

Here’s how mine look.


Is that the 3D printed piece?

That’s the washer I used, it would look better painted black, I think

The actual part sits against the core of the wheel recessed which I think looks better but that was gonna be my Last resort if we couldn’t find the file.

Yep that’s the 3d printed one. I used socket heads. Cap heads might look better. Like you say @WARMAN, the wheelside is contoured to spread the load.


The washer actually does sit against the hub of the wheel, it just appears not to, compared to @bigben’s as he has larger wheels and the core seems to be further into the urethane if you know what I mean. The hubs on flywheels are 45mm so I got a 45mm washer
