You run one yet?

 

You run one yet?

I have not. I would like to hear from those that have.

 

That looks awfully alot like a Mori seiki mill..... You are milling a gear and pressing in the bearing? Cool!

 

This topic has been brought up on TY before. Some creative pioneers created this product years ago. I think the primary topic of concern was with regards to life of the jackshaft where the needle bearing runs. Does the needle bearing (which is a pretty hard metal (52100 chrome steel)) begin to wear a groove in the shaft (lesser hardness than the needle bearing) after miles and miles of running? So does the needle bearing gear last "forever" but now the shaft needs replacing after "X" number of miles?

 

Gear doesn't turn on shaft , as long as bearing fits right day one there should not be an issue

 

Zero gear or bearing or shaft failure. This has been well used over two seasons by hundreds of buyers

Only in reverse. Agree, key is that it fits good when installed new.

 

Yes but no load on gear in reverse

 

I am changing the gearing on my sled so I ordered on of Dave's top gear with needle bearing to run.

 

After a full season of riding this gear and shaft look like they did the day I put them in. No noticeable wear.
Opened chaincase to change oil and inspect.
All looks good and going back together.

 

Two seasons ago I installed a new bushing from Canadian Bearing and had to fit it to the shaft and it still looks good. This time during the annual service I also put in 10ml of Rislone ZDDP additive used for flat tappet engines. The zinc should be helping against wear.

 

I've been running the needle bearing for two seasons on my turbo Viper 240 hp. Took my chaincase apart to change my track. Shaft and gear look great. 4000 miles on the shaft and gear.

 

For install with this bearing does it use all the factory spacers / washers?

 

Yes
