I took off the 9" wheel for which I couldn’t get the runout ok and put on some Superstars I picked up off Trampa, surprisingly I still had runout issues and also an adapter fitment problem on one side, I suspect the trucks which came with the second hand board may not be perfectly true.
My solution turned out to be a couple of slim 4mm washers on the rubbing side, I had to do this for each drive - trial and error. Point of note - the wheels can be tuned to a certain degree, if you get a rub point, try tightened up a snip the bolt/s on the wheel point where the rub is, this may help.
And lastly just to keep me involved for some reason wheel #2 had a spacer which was too long to keep the bearings seated, no idea why as it’s a standard spacer, I had to file off about 1.5mm to stop the wheel moving laterally in the drive.
Tired now of fighting this bastard, maybe some pics tomorrow,
3dServisas supplied a few washers, 2 X 0.5mm & 4 * 1mm.
The recommendationin the manual is to not exceed 2 washers per side, I managed to keep it at that with a total of 1.5mm on side & 2mm on the other.
They are acceptable now, I have to state again that the machining to me looks perfectly accurate (checked on glassplate),so deviations are likely to be 2nd hand trucks used for jumping & injection molded hubs which would have more runout than machined alloy
Rough and ready but importantly should keep anything larger entering the cooling ports, this is a sand runner so if the motors die from ingress I’ll just switch them out for properly sealed HK ones that came on the market recently
When back together and set right I’ll secure the spur with green locktite & blue locktite the rest. Will need to read @Deckoz’s post on setting backlash again
The POM gear is 15mm deep, the spur is about 14mm iirc, you want to get the top of the spur close to the rear of the wheel gear without rubbing, basically you should not see any part of the spur teeth through the gap otherwise it’s not engaging fully
After fixating on the La Croissant earlier I got back down to business and installed the focboxes, plugged in the USB then disaster struck…a big disaster.
Setting the drives up in the VESC tool O didn’t think to do the final loctiting to set the drive plates…CRUNCH
Can you guess? The grub screw turned itself out and momentarily stuck itself between the spur and the drive wheel before snapping off a section of POM teeth. I will probably need to wait till July to get a new drive wheel on this side, I doubt my Heath Robinson fix will hold
Superglue, VHB tape and a strip of Ti, sux to be me
