How many washers?

Changing from AT to street on my Bamboo and I'm not sure how many spacers to use. I watched the video ( ) and looked at the manual from W.Jordan (Evolve GT - NEW Manual). The video mentions that future versions of the truck will only need one stainless steel washer behind the drive gear and one black washer between the drive gear and wheel.

My question is how do you know which truck I have? Also the manual above seems incorrect. There should be washers on either side of the drive wheel.

Thanks.

 

When did you buy your board? The video is 4 months old so try to place your board into the either the legacy or newer model trucks. When he say's soon to be shipping I'd pad a minimum of 2 weeks to a month for "soon to be shipping" which would be around July. Best to call Evolve to fully confirm which trucks you have. Sure the metal axle to aluminum body of the truck is what will be different due to the change in number of washers/spacers.

Nice video on adjusting the belts. One tip to use that MetroBoard uses is to download a guitar tuner and pluck your belt to resonate a tone. This tone then is mapped to a frequency in the guitar tuner. You can tune both sides to be practically identical this way and its more precise than they eye or feel. Didn't know if one side was tighter than the other that tit would affect the rate of rotation for the wheel. Good to know.

I do two larger washers first. Drive. 4 smaller washers. Wheel. 1 small washer, nut. Both sides. Works well. No rubbing. Smooth rolling.

 

1 washer 2 spacers. I talked to the California Customer service office. That is necessary for the first batch.

 

My street setup (received yesterday) only had 1 washer on both sides. My AT setup now also has the same as I understood number of washers should be equal for both setups.

Not sure now if I need to change the setup for the AT to 4 washers??

 

on the first few production runs they say 2 washers for the driving wheels each, but this may become just 1 each later on. So if you got it this way from them in the latest production run, seems like they have changed something in the truck design or something. You could call to clarify this.

 

I will drop them an email to make sure. All looked fine using the setup with 1 washer.

 

I think the extra washers connects the pressure on the bearings/wheel spacer to the larger truck washers and the axle nut so there is a complete connection. I use the same for street and AT. Maybe 3 would still connect.

 

My bearings have built in spacers and speed rings, but i still use 3 speed rings and two washers for the drive wheels, as the built in ones take the place of 2 speed rings, 1 for the outer and 1 for the 4 that are suppose to be on the other side.

 

Why would you add speed rings if the setup is already factory complete? Any advantages in doing so?

 

I did not "add" any speed rings by default you are to use 4 speed rings on the inner side of the driving wheels, and 1 on the outer of the wheels just before the wheel nut. So if you have bearings that have in built spacers and speed rings like I said before, you don't need as many, just 3 instead of 4 for the inside of the wheels, and the outer of the wheel needs none, just the wheel nut great for when you change your wheels or do servicing, as you don't have to keep track of the little speed rings.

 

So to understand:

Street kit has in my case 1 speed ring on each part (standard as delivered)

When switching to AT I need to use 4?

 

No watch the video, it says to use 4 all the time for both Street and AT for the inner of the drive wheels

 

That's strange as my board straight from the factory does not have 4 installed. So it might be a change in the setup from evolve. I have asked them about this

 

Good idea, as their manual and video should be updated

 

On my carbon GT which was from the 1st batch received in the U.K. I found that the tolerance was just too close with 4 washers so I added one in on each side of the drive wheels making 5. Without that extra one the gap between the belt cover and tyre was less than 0.5mm which although fine at standstill had the potential to rub at speed / cornering. It's all good now

 

Official answer from Evolve:

"There was a change in the truck style during manufacturing.

The newer trucks only require one (1) speed ring between drive gear and wheel."

 

there you go, and if you want even less parts to worry about, go with bearings that have them built in
