Spindles egged out- Check out my fix

[Tod]

What do you think about this repair. Will it be ok having a longer bolt compared to the shorter stock one?

So last year my top bolt came loose on my spindles -this then egged out the top hole— so now the small gap has been completely welded shut —along with welding the egged out hole shut and re-machining it flat and a new hole drilled.

Yes, I've done this same mod to a couple in years past. Bushing in the middle with longer bolt.

The picture I posted is not a fix for an egged out hole. It is the mountaintec front end design and will prevent that hole from egging out.

Yes, we caught it before the hole had too much damage.

I dont know if all Nytros have this or not but mine has a thick steel washer between the ball joint and the spindle. Looks like yours didn't have this which probably added to the issue. (sorry for the crappy pic, its all I have right now)

Both mine + the Wife's nytros have this also, 'lil more "meat on the bone" than that shitty original way.

This is interesting... What does the longer bolt and shim do for geometry, appears to relax it a bit, a little higher too...

Keeps your skis tracking straighter thru out the travel of the front suspension. Makes it handle better.

You are correct, this is my rebuild with all new Yamaha parts, a thick metric washer is supposed to sit on top of the spindle, not sure how it would egg out with that on as shown in the pic. Mine felt hydraulic solid after rebuild and still do. I hit them with Wurst synthetic waterproof adhesive grease every year, amazing lubricant. Those are my fresh black powder coated spindles that lasted all of three hours! Look sweet w the black A arms!

If those have been powder coated they will fail again. the powder coating process weakens aluminum, especially cast pieces like the stock nytro spindle
