i have a pair of gen 4gs drives and a set of triple links. i have both the 10mm and the 12mm axel hangers. they have very different profiles. Which hanger should I use and which clamp should i buy?

The hanger with 12mm axles is 20x20mm, and the 10mm axle hanger is 22x22mm with 6mm chamfer (designed so they could fit Apex Jump drives also). The 10mm axle is the newer/most updated version and is a bit stronger I believe (less connection points where things could loosen up, one continuous axle all the way through).

No loctite, although you certainly could use some.

Hi, I got the moon drives for the hypertrucks but since both the moon drives and the hypertrucks are discontinued I’m trying to get a replacement gear drive just in case something happens to the moon drives. The 4gs look awesome but I don’t see how can I get the clamp for the hypertrucks. Let me know if you have or know how to get it.
His domain expired and he’s away on a trip. It wont be fixed till he gets back

I ran into an issue assembling my gear drives (using Newbee 44/11 4GS with Reacher 6395 motors). There are M4-30 screws that attach the motors to the gear drives, but when I use them, the motors don’t spin / have greatly increased. Anyone else encounter this / have any advice?

Check if your motor shaft is rubbing on the inside of the gear drive cover. May need to file down the motor shaft a little or space it out with washers.

I’ll remove the cover next time I work on it. Hopefully that’s it.

For this reason Newbee sells spacers that insert between the motor mounting plate and the motor and reduce the effective length of the motor shaft. I think it was added after several folks from this forum reported interference with Reacher motors. It is technically simple enough that you could fabricate yourself.

Oh, a pair was included. You said they go between the motor mounting plate and the motor. Thats unfortunate. It likely means that I’ve got to take the motor gear off which I’ve already applied retention compounds to. Also, it being carbon fiber will likely decrease the heat sink effect on the motors from the gear drives

I just realized that with a couple more holes it could likely work between the motor mounting plate and the gear drive.

Pinion gear for Newbee 4GS especially with retention compound is near impossible to take off without destroying the pinion due to the integrated bearing… Yeah ask me how I know.
I am not sure how you plan to stick the spacer in without taking the pinion off, but I wish you the best!!!

Its an issue with reachers, something like the shoulder of the motor shaft causing the pinion to be a smidge too too far into the gear housing and binding on the cover. It is super close. I put a .5mm shim washer in between the motor mount and the gear drive because I didn’t want to remove the pinion also.
That let me fully tighten the bolts and prevent it from binding but also not make so much space as to let the motor mount get misaligned
Couldn’t find anything except this disassembly photo but you get the idea. Added a smidge of grease to make them stick in place and also keep dirt/water out. Worked well except the grease was pretty thickened up after about 1800miles.
might be better to use aluminum foil if you’re worried about heat transfer. Im not - the reachers seem to have plenty of thermal mass and the air movement is likely doing orders of magnitude more cooling without adding thermal compound to the motor/mount/gearcase/hangermount interface that is then cooled by air anyway BUT that’s just my opinion - haven’t actually tested anything.

Reachers motors is a wee bit wider at the base of the shaft. Same issue with it on BN-Drives, easier fix with BN drives tho, a bit of filing and sanding.

Unfortunately, I’ve only got access to the skateboard every few weeks, but next time I think I’m going to try two things.
-
Use the gear drive casing a guide to place holes in the carbon fiber spacer for the screws to go through, that way I can place the carbon fiber spacer between the gear drive and the motor mounting plate. The issue with this is it might lead to a slight misalignment between the motor and the gear drives
(no longer getting the positioning from indent). This leads me to my second idea. -
Cut an 8mm wide slot into the carbon fiber spacer so that I can slide it between the motor and the motor mounting plate.
Regardless I think there should be a note on the website with a list of commonly used motors that require the carbon fiber spacer. That and a clear written up to date procedure for installation.

this is what @Ac53n did for the shims he sells. makes it easy to add or remove as needed without removing whatever gear you’re running
