One Piece Layshaft Gear Binding in x6sq

[MeBeMikey]

I have always ran associated top shafts where it has the spacer and car runs perfectly. Now, I just installed the Xfactory one piece Layshaft an gear and it binds the tranny up. Iv taken apart the tranny 4 times now and installed my used (still good cond) associated Layshaft with spacer and it works perfectly.

Am I missing something? Has anyone else had an issue?

Thanks!

PS! I go my UK F2 class rating! I'm off to the Nationals next year!

Mikey, please double check to be certain of several things: Are the teeth perfect? Is the old gear + spacer the identical width to the X Factory gear? Is the shaft bent at all? Is there any sort of burr or deformation where the two bearings go?

We have never had an issue with a single #5210 top shaft. They are made for us by M.I.P. so you know they are top quality. If there is a problem with the part, please return it to the store where you purchased it for a replacement. If you are in U.K. I know X Factory U.K. will take care of the model shop. If you bought it some place else, we will take care of the shop.

I will have a look at it again. Its gota be something simple. I deburred everything but I didn't check for it being bent. I also don't see any machining issues with it. I'll take it apart again and have a look.

With the one piece layshaft, do you need the spacer? I seem to recall trying to fit the AE part when my XF one was worn and couldn't because I didn't have the spacer...

The spacer im talking about is the long spacer on the AE part. I haven't taken apart the case yet. I need to check is the bearings slide all the way on too. I'm sure it's not the shaft. It's gota be something I'm doing.

At the last regional my car was making the worst EVER diff screeching and grinding and barking noises. Day before it was fine with a slip only here and there. Every time my car wet down the straight I couldn't help laughing. It was as if my car was telling me "Don't pull the throttle" but I gave it all. I couldn't clear any jumps either, but I still made the B. Goes to show that going slow is fast in the right conditions. And I need to have a spare diff.

With our #5210 top shaft, you do NOT use the AE spacer. The spacer is built into our shaft.
