Worn hubs or poor ktm QC?

Recommended Posts

Ive recently purchased a 2015 250 six days and while changing the tires i noticed the rear wheel spacers wouldnt turn. I purchased new bearings and seals and when installing them it seems the tube between the bearings is preventing the bearings from sitting flush in the hub.   Basically if a bearing is completely seated i can see the tube is to high to let the other bearing seat.   I can reassemble by leaving the bearing about 1.5 mm above the hub seat which will take the pressure off the bearings and let them move freely.

 

fwiw the front hub has a similar issue.

 

Whats going on?  

 

1. Somehow both hubs are worn at the seat

2. The inner tube were cut wrong

3. The hubs were cut wrong

 

Any suggestions what the cause could be?

weird.....hard to believe ktm made a hub like that.

maybe last owner put in wrong size tube??

spacers may be a bit hard to turn by hand  when pushed into a new seal.

also sometimes the tube between the bearings is pinched in there kinda tight....normal

the previous owner submerged or used pressure washer to clean. I have seen more pressure washer damaged bearings and seals than I can count.

Standard on a KTM, when the axle is tight the spacers, axle tube and center of bearing become one solid piece allowing the bearings to roll with the wheel movement. Do not worry about it.

Op doesn't have the tube perfectly centered, if it's at any kind of a slight angle one of the bearings won't seat.

If your hammering bearings in it's hard to get it to stay..

Not possible as the spacer centers the tube.

Explain? Spacers sit against the outside of the bearing..

On this bike the spacer has a shoulder for the seal then a shoulder the bearing rides on. Then it protrudes in to the center tube... basically the axle rides on the spacers not the bearings
