hyfax wear theory?

[1050THMPR]

The larger wheels are the cure.

I have additional set of the stock idlers outside the rails and just ahead of the rear axel. With these idlers in place the wear on my slides is very consistent along the horizontal section of the rails. So, I would say there's a benefit from addition of standard wheels as well. With the strap pulled up 2-holes I see almost no wear of the hyfax on the curved section. I've been using the wide "high performance" slides with graphite or some other internal lubricant and have just over 2000 miles on them this season.

And, just to be clear, in the vernacular of science we are discussing a hypothesis here, not a theory. To be rigorous in this exercise we would develop a protocol, test our hypothesis, analyze our data and then propose a theory to describe these data.

I just like to be concise.

Arteex, you gotta lay off the POT man!! HAA!! HAA!!

Aluminum has been used as a heat sink for years. Its ability to dissipate heat along with the fact that heat causes wear has been well researched and documented.

If the extra idler wheels are the answer why wouldn't they come with them? In the old days that's all they ran. Are the stock idles an accessory kit for the rear? It’s a good idea seeing how there’s a long span of rail with no wheels. How much and do they last? Sliders are not expensive or hard to change and may be just one of the yearly maintenance things like changing oil.

Don't even get me started on the tribolgy of polyethylene on steel and rubber.

The bits you need for adding another set of stock idlers will run about $200 - check the Port Yamaha web site and use their parts finder system for the best prices. You need to order 2-each of the parts identified in the link below.

1050THMPR - It ain't the pot, it's like you know, sometimes you think raspberries but penguins won’t stay in a wheelbarrow after waffles.

I bought the geniune Yamaha Marginal Snow Wheel kit. I think it was around $85-$90. I have +/- 4600 miles on those little wheels, and just had to replace one because it (the rubber) flew apart. Yamaha does NOT sell just the replacement wheels. That would make too much sence. So I bought EXACT replacements from Dennis Kirk for $18.95 each. They are PPD wheels with the same part # as those that came in the kit. I never figured those little stroller wheels would last that long, but they outlived the subframe. Go figure. Raspberries...wheelbarrows????? WTF???????

 

[grizztracks]

thanks benny. I was afraid they wouldn't last. It just seems like alot of pressure for a couple of small wheels. I just replaced the sliders on my vector for around $30. even if I replace them yearly on my nytro its not overly expensive or difficult (not a bad idea to drop the skid and check it over anyways). I may spend a little more and try some aftermarkets.

Cool, What was the Dennis kirk part #.

 

[benny]

Part # for replacement wheels is: 04-606 This is the Dennis Kirk part #, not a Yamaha part #, just for clarification. There phone # is 1-800-328-9280. Hope this helps and saves you all some $$$$$$. Penguines????? WTF?????

[Daranello]

Is that for the mount kit and wheels or just replacement wheels??

That is just for the replacement wheels. The whole kit is in the Yamaha catalog. Part # SMA-8FA95-00-00. The catalog price is $69.95(u.s), I thought I paid more , but that was two years ago, and I can't remember what I had for breakfast. Sorry for the confusion on my earlier reply. My wife was hollering at me for supper. You could chip a tooth on her mashed potatoes.

 

[grizztracks]

wheel kit cost $52.46 at yamahasportsplaza.com. I'm going to give it a try.

Thanks for the info benny.

Wow! Now don't forget all the variables in your testing!

I was concerned with mine at first last season as they seemed to wear quite quickly right at the curve on the rail but now they have been at the same wear point for some time - So at 5600Km I cannot complain. Silly question: Can these things be turned around from front to rear to get even more wear?

 

[grizztracks]

You probably could by drilling a hole and counter sinking for the screws but if you’re going that far just replace them. They’re not expensive. Mine wore in the back. Can anyone explain why? It must be the suspension setup.

I needed limit straps for my vector so I added the marginal snow wheels to my order.

 

[arteeex]

Just for giggles I looked up the cost for the extra idler setup like I have on my sled. It was $243. I don't remember paying that much in '08, but does help explain the big black hole in my bank account that shows up about December every year.

The marginal wheel kits are cheaper, but those little wheels need to spin so much faster to keep up with the track. I figured the rubber and/or bearings would get smoked more often.

I know the sliders are cheap, but I hate the job of replacing them more than once in a season. And, of course, you never know they need to replaced until you're 80-miles from nowhere. The money spent on additional idlers of either style is cheap insurance.

 

[benny]

The bearings on those little wheels are removable/replaceable, so you can clean and repack them, or pitch 'en and get new ones. I did repack them at the begining of this season when I was repacking the driveshaft bearing. No penguine reference this time???? i am disappointed!
