Hubs and Wheel Bearings
Hubs and Wheel Bearings…INSPECT THEM!!
As with any motorcycle repair work consult the service manual and a properly trained mechanic… Any doubts have someone qualified do the work. Legal mumbo jumbo out of the way.
Motorcycle wheel bearings are an important part of your maintenance schedule and should be checked at every tire change and/or if the wheel is off the ground. Check for side to side movement, if movement in your bearings, have them looked at.
With winter set in I figured I would give my KLR a proper going over, look at every nut and bolt on the 650. I had a list of thing that I wanted to make sure got looked at, and new tires was on the top of the list, wheel bearings was next.[phpzon keywords=”sealed ball bearings” num=”2″ country=”US” trackingid=”stinsoadvent-20″ templatename=”default” paging=”true”] [phpbay keywords=”sealed ball bearings” num=”2″ siteid=”1″ sortorder=”BestMatch” templatename=”default” paging=”true”]
I was all set to put on a new set of tires today and went to remove my wheel bearings figuring they where in need of replacement (40k on the motorcycle).
With the rear wheel already removed, I set out looking at the sprockets and the cush drive (rubber set of wedges behind sprocket cover), all was looking great once I managed to get the dirt and grime washed away. Now onto where my day went form looking like it would be quite productive, came to a grinding halt.
I went to remove the dust cover from the brake side of the rear hub and found this as shown.
In the picture, I thought is this a spacer.. a washer for the dust cover….. NO, that is part of my rear hub..I proceed to tap the wheel bearing out and plop out it comes. Snap ring was already laying on the floor beside the broken piece…no this is not looking good..so I go to remove the bearing from the opposite side and yet another piece of the hub comes out with the bearing, this one looks like a small thin spacer…. hmmm what’s going on here?
Here is a picture of the brake side of my hub.
Here is a picture of the sprocket side of my hub.
You can see the damaged seat area of the hub, no way will I reuse this hub. If I was stranded in the middle of nowhere I would consider nursing the bike to a shop to have it outfitted with a new hub…no way would I recommend to anyone to put this back together and continue riding on it…. it’s a disaster waiting to happen!! Once a hub is cracked the whole assembly is compromised and will fail..just a matter of time.[phpbay keywords=”motorcycle wheel hub” num=”1″ siteid=”1″ sortorder=”BestMatch” templatename=”default” paging=”true”] [phpzon keywords=”motorcycle rear hub bearing” num=”1″ country=”US” trackingid=”stinsoadvent-20″ templatename=”default” paging=”true”]
I have the proper tools for removing bearings, so that’s not it, and I hardly tapped them to get them out..wow … this is odd….upon further inspection of the hub it is cracked and the pieces broke away and now I am sourcing out a new rear hub…this will run in the $4-500 price range.
Not including the rebuilding of the wheel, re-spoked and truing/balancing…. so quite the expensive undertaking, and back to the wheel bearings, all 3 were in dire need of replacement…full of rust, and no grease… makes for a poor situation all the way round. So do yourself a huge favour and inspect your motorcycle wheel bearings and hubs on a regular intervals…besides saving you from some costly repairs it could just save your life!
