Fearing the worst... please tell me I'm wrong..

This was an excellent explanation. Thank you very much for taking the time to write it up in such good detail. I get it now! Given that many of these parts are Aluminium alloy it's no wonder Doc was pointing it out. Again, information such as this is what makes this site special to all of us Spyder Riders, new and experienced alike. :thumbup:

:agree: Thanks a bunch. :thumbup:

... heating the race side and cooling the bearing may be necessary, as may the use of a press for installation....

:agree: BUT ONLY if there is no rubber dust seal on the bearing. Rubber and hi-heat don't mix! :roflblack:

Also, be careful heating the area the bearing is pressed into. You can actually "Over-temp" the area and cause associated and unintentional "heat tempering". This can and will change the structural capability of the component by making it less flexible and more susceptible to stress cracking due to flexing. nojoke

When it comes to "heating and shrinking" for bearing installation, make sure you know what you're doing or it can get even more expensive to fix! :yikes:

Again, just my 2-cents.

I've had pretty good luck through the years using a center punch to expand the race surface area and then using loctite on the bearing race..

For those that do not know, this procedure is called "Staking" a bearing in place. It is widely used in many industries and works well when combined with a bonding agent like Loc-Tite (we use to use some stuff called "Gorilla Snot").

What you are doing is basically expanding the outer race by "deforming" the very top edge of it so it "digs into" the mating surface. Like I said, works well just don't slip and "punch" the mating surface! This could cause micro-fractures thus reducing the life-cycle of the component & premature failure.

Step 1) prep installation area (clean hub!)
Step 2) inspect area for signs of damage or excessive wear
Step 3) apply bonding agent to mating surface (hub race)
Step 4) install bearing ("dry" press fit)
Step 5) "Stake" bearing in place - **ONLY IF NEEDED**

But at less than a $100.00, if bearing area of your hub is really that bad - I say buy a new hub to put your new bearing(s) into! :2thumbs:
