Xray t4'15
#451
Well this car is the first Xray car I have built. It is pretty nice, the only thing that I have disliked so far is the gear diff. Trying to put the gasket, and o ring on the top and sandwiching them together is rather difficult. But the rest of the car is very nice! Can't wait to make laps with it tonight!

Difficult to install at first, and the silicone-induced swelling of the ring renders it useless after the first use. As stated above, the diff can be assembled without the outer ring, and it won't leak.

Well, its put together so, next time I swap out oil I will take the little guy out! Where was this 2 hours ago

nope, that is the correct way. If you follow the instructions the spur lines up centrally in between the top deck sides. Mount the spur the other way round and it can rub against the top deck.

The way that I've put spur gear in, it's NOT in the middle, and it is very close to one of the top deck's sides (just under a mm?), and I've had a bit of trouble aligning the pinion with it (it's quite out on the motor's shaft, I can almost see the setscrew).
I've been amazed at some of the insanely close tolerance on that kit, so much quality! But it's made me doubt my instincts... With this sort of quality, less a mm of clearance might just be totally fine. But the way I'm having trouble putting on the pinion, I'm having my doubts.
So here I am, checking with fellow people who have offset spur gears on their T4'15 and asking: do you have the wide side of the spur toward the motor or toward the battery?

But check out how freakishly close that comes to the top deck (and how much of the motor shaft):
I'm pretty sure I should relax, I'm just not sure if I should relax about a) how close this comes to the top deck, or b) following the manual closely.

spur
you have something wrong in assembly.
you can see way more spur layshaft on motor side than there should.
images in manual show deep side spur edge in line with edge of shaft.
your photo shows a mm of shaft poking out.
i did mine exactly to images in manual and mine centered.
screws go into spur from same side as numbering for teeth count then is installed into car with numbers facing motor side.
some motors you have to put pinion grub on motor side as well.
tekin for one.

The manual emphasizes in two separate diagrams that the narrow side of the offset spur gear should go on the side with the spacer, which should go on the side of the short belt (motor side). See this album, for the diagrams in question, and photos of how I've built it:

Didn't have that problem with my previous car:

This might sound a bit extreme but with a new car I'll build it (to the manual) rough once (except for shocks) then pull it apart again and build it with great care
Helps you get to know the kit, doing it this way since 2007 with Xray's, I can just about do it in my sleep without stuffing up...

I doubt they changed that part of the manual from the 2014 car, so I bet you built it or installed it incorrectly. The screws go on the shallow side of the spur and the hub on the deep side as shown in the cutaway view below.

I'm going to try flipping it, that should put it more or less in the center of the top deck cut-out, and make fitting the pinion easier... Any possible downside, you think?
