Hey guys, I just filed a flat spot on my Turnigy SK3 motor shaft, and I’m not sure if it is large enough. I have a picture of it, but the area where the grub screw will sit after using the Enertion Motor mount (a few mm from the front of the motor shaft) is a little more filed down than the front, which is shown in the picture. Do you think this will hold with some loctite, or would it be safer to file it down more?
I tightened the grub screw until it started to get tight, and I could rotate the pulley a little one way and it would stop, and then a little the opposite way. This is just hitting the 2 edges of the flat spot, right? Will that be a problem?
Another quick question. When I’m installing the enertion pulley onto the enertion motor mount, how do I ensure that the pulley doesn’t touch the mount? I see that there is a circlip (I think) flush with the motor. Do I need to bring that out to separate the mount and pulley?
@chinzw My enertion pulley only has 1 screw [quote=“chinzw, post:11, topic:8779, full:true”]
I have an SK3 on my board, didn’t file anything and its holding strong with the 4 screws from the DIY’s pulley

Well by you fastening the pully to the shaft…it shouldn’t move towards the mount … Just make sure you torque down on that mount and use thread locker so it doesn’t move at all… A loose mount can cause the belt to move … Rubbing against the wheel or making it come off… And that stress could move the pulley on the shaft
I have another question regarding the enertion trucks. When I put the pulley in the wheel and put the wheel on the trucks, there is only a few mm of exposed axel. Only enough to just get the bolt on and penetrate the bolt about 1/2 of the way through. These are enertion trucks, so I thought I wasn’t going to have this problem! I’m using 83mm Blank pro wheels as well.
