Hey just to let you guys that were at the race day last week know I got the bearing off the shaft by pulling it off. Nothing broke. Do I still need a new shaft? Oh and also how do you post a picture? Beacuse I tryed to but it says that I have to change the file name how do I change it?
U can always post on iroccs face book.
You can use photobucket. Get everything apart. Load up the xray x12 manual and build the axle as indicated. No secrets really. Dif should be smooth but spur shouldn't be able to turn with both outdrives being held.
Xray manuals are legendary in their detail.
Obviously replace any bearings you glued. You will likely never get them clean enough.
Ok got it thanks Valk I will read the x ray manual 3 more times and luckily I don't need to use glue.
Oh and I took off the bearing that was holding the tire to the shaft waaaaay to hard
I read in one but reading it again I just found out that this is probably the best build guide I have ever used! I think they are probably better that tamia! (This is just my opinion).
there is really not a lot to a pancar dif. some balls, a gear and some bearings and nuts. i think the xray has a thrust bearing stock so if you build the dif to spec and check that its tight after every race, it should last a very long time. once its together, calibrate it as such;
hold the two tires with your two hands, use a thumb to try to turn the spur gear. you want the dif tight enough that the spur takes a lot of effort to move. the hotter the motor, the tighter that needs to be. I personally run my dif fairly loose. basically if i put the car down and its spools or barks when i gun the gas, its too loose. same with buggies and slippers clutches. thats with a 13.5.
pancars are great. if you can keep them off the walls there is very little to go wrong with them.
We'll I will put it back together than THE RIGHT WAY lol
AHHA i figured out the problem! if you look at the x ray x12 manual you see 2 washers squishing a washer with little balls in it. i thought that was a bearing! so that is why the diff was super hard and i also was thinking that you put the 2 flat washers at the back but i was wondering how that would sqwease together. Turns out that you needed washers that were in a cup shape to squeeze together. i don't think i have those cup washers so i might need some. if i find some i will let you know.
two washers with little balls in it would be a thrust bearing. they put that in there to take the pressure off the bearing that normally goes inside the outdrive to allow it to spin freely. some pan cars push against that bearing with the axle nut which quickly wears it out. a thurst bearing can sustain the load for long periods in the direction axial bearings on your axles cannot.
consider yourself lucky. with most pan cars thats an aftermarket option lol
ya gorden says that the guy that he bought it from upgraded the heck out of it
i am looking for the 2 cuped washers now and if i don't have any i might need some and once Iinstall those my pan car is ready to go for the winter season!
do you have;
13.5 motor
1 cell esc
1 cell battery
?
I have everything exept a ESC but I am getting one. I have a 1s lipo and a 13.5 sensored brushless mottor
Oh and of corse I have a recever. Lil
Ya I don't have the cupped washers and I checked the shaver shop and they don't have. I also checked the bag of parts there was no cupped washers. Does anyone have a pair of the 2 washers? (The ones that squeeze together to provide tightness)
Pretty sure the only peeps in the club with an xray are the fantetti's
Do crc pancars use them?

Are you talking about the cup washer that goes just before the diff nut? If so, then yes CRC uses them, and they should work fine on your car.. I thought the Xrays ran thrust bearings on the diff?

Here is what you are looking for
http://www.slapmastertools.com/thrust-bearings.php
yes it has a thrust bearing but there is 2 rings after that squish together to provide tension so the gear doesn't slip. that is what i need.
the cup rings go after the thrust bearing and after is the nut.
The first hit on google for x12 manual shows exactly how the axle goes together assuming oem parts. Looks like it is a captured thrust bearing that sits on a colar pressed into the outdrive. Then the washers fit the thrust bearing as if theu form a spring. Then the nut.
With my slapmaster thrust bearing the nut snugs right up to the thrust bearing.
the problem is i don't have the 2 washers at the end.
Try to.build it without the washers. Or use a normal.m3 shim. Since adding a thrust bearing I haven't used the thrust washers.
Ok I looked at a photo of the axle. It should work without the washers, but I would recommend using them. They appear to be the same standard washer used on a pancar. That washers job (imho) is to act like a small spring, and to absorb some extra shock, in the event of a collision with the boards, and to apply even pressure to the thrust bearing.

Ya I tryed putting the tire on but the gear keeps slipping. I tryed useing the bearing at the end that gorden gave to me and I tryed Neal's bearing that he gave to me but it still slipped. So it must be that I don't have the 2 cupped washers or I am useing the wrong bearing.
Add some washers to the axle before the nut. If the but bottoms out on the shaft then it won't apply enough pressure.
Ok I will try that.

look on page 17 it is very clear on how it needs to be put together.
OK i think i tracked down the problem. the bearings that was in the bottle were slightly to small so the part that whent on the inside of the bearing did not fit. so it sat on top of the bearing so the peace was to far from the plastic mold on the rim so i was putting it together right but the problem all along was that the bearing that was silver that i put on after the blue bearing fell apart was to small! (that is probably why it was so hard to pull off lol) so the bearing that i needed was blue and it was the same diameter but it was bigger on the inside. does anyone have those? if not i can order some.
