What do you guys think of this as a fix for the bearing spinning on shaft behind brake??

[yamamarc]

I have mine sled apart and was looking and thinking of attempting to replace the OEM with a bearing with a set screw collar if I can find one!! The collar with the set screws would be on the inside of tunnel. I would need to measure but it may work?

Sorry I can't post pic but this is the type of bearing I am talking about

All the apex sleds have what you are talking about already.

Is the bearing on the apex a 6009

I researched with my local bearing outfit and they told me they couldn’t source that style bearing in size needed. Was my first attempt at a solution.

Have you tried all the manufacturers Travis
Skf, fag, timkin.. ... I will contact our suppliers at work to see also!!

Exactly...I searched extensively around and nothing is made with collar in the size we need.

Also, it would be near impossible to get at that collar screw with the design of these sleds.

Lots of guys have been thinking about this for many yrs. If it was simple it would have been fixed already.

Yep, you won't find one, been there done that.

I opted to install a 1/16" thick o-ring between the inside snap ring, a set screw thru the shaft and some green 638 loctite to hold the SOB from spinning with a new shaft and new bearing with a .001 slip fit on it. Last I checked the set screw it was still tight, but I'll re-grease all the bearings again this fall and will have it apart at that time. I'll report my findings. I've put 1690 miles on it since, and the new shaft and bearing went in at 2300 miles.

I got lucky over 3000km and no wear on shaft so I am going to make dam sure it will be secure before putting everything back together!!

I am tempted to pull the shaft out and put 4 beads of weld at 90 degrees of each other and mill it down to a slight interference fit

We use locktight 638 and 675 all the time on electric motor bearings and have had excellent success. The shaft and bearing must be absolutely free from contaminates!

I have loctite 620 for slip fit bearings going to give it a shot

Hey Marc! Can you find a bearing with a larger I.D. and press a collar with set screws into it.

Never thought of that Andy!!!!! Great idea I will looks into it!! It would be easy to machine a interference fit collar with set screws.


Andy this is something you may want to address right off the bat on your new 2020 if the didn't correct it!!!

 

[hellflyer]

Yes Marc! Already on my mind along with other things,
