Spindle bushing removal, premium bushing upgrade

[grizztracks]

I order a set of premium bushings from UP bushman. The upgrade kit is all stainless steel with a full length single bushing that fits snugly in the spindle and should last much longer than other options. Here are some pictures of removing the OEM bushings and installing the kit.

Clean end of bi-metal bushing and locate slit:

Use a tapered punch to roll the bushing starting at the slit:

With the bushing rolled over use a socket or bushing driver to drive both bushing out at the same time:

Premium bushing kit:

Clean the spindle then drive/press the new stainless bushing in:

Grease bushing and anti-seize the spacers:

I've been looking at these myself, are the spacers the same size? or different sizes to allow more ski stance options.

I didn't measure them but I believe they are the same size as stock.

Great post grizztracks, a lot of people have been asking about spindle bushings and this mod is by far the best upgrade.

Perfect timing for this thread, I have UPbushman's bushing kit on the way!

I did Upbushman's spindle kit last summer and it's still as tight as when I installed them. If you have any slop in the spindle, I'd suggest going to him for the fix, it really worked on my sled. I can't believe that the stock bushings are just a thin split bushing....

Yeah, I think what really wears them out is the steel inner sleeve. Water gets in there and rusts the sleeve. Then the rusty sleeve acts like sand paper and rapidly wears out the bushings.
Makes sense to make them out of stainless steel

Use a piece of threaded rod and some washers to draw the new bushing into place. Less pounding can be a good thing.

The bushing is stainless steel and as long as the spindle is clean it drives in fairly easy. In some cases the spindle has egged out and the new bushings are loose. UP bushmen recommends a special Loctite (#640 Piston Sleeve Loctite) in his directions if that's the case. Pressing the bushings out and the new in is the best method but not a must. The spindle should be able to take driving the bushing in as long as you don't get carried away......if they can't we shouldn't be riding with them.

I used a big C clamp to press the new bushings in, works slick
You can use different skis with this kit. The sleeves are 3" long to fit the Yamaha trail width skis. I my case I'm running Polaris Gripper skis and they're sleeve length is 3 1/16". So I just simply installed a 1/16" thick washer on one end to act as a spacer.
