Hi Does any body know if the Cooling Fans are all the same..xb9 xb12? Can you replace the bearings in them | ||

I believe all the fans are the same. There is a great thread discussing the fan construction (and the cause for earlier failures) here: http://www.badweatherbikers.com/buell/messages/142 838/225002.html It would not be easy to replace the bearings. Here's what the author of the original post had to say about replacing the bearings: ---------------------------------------- "No it's [the fan] not easy to disassemble. 1. I drilled out the ultrasonic welds on the fan hub to get the fan off the shaft and used ABS water pipe cement to reattach it to the fan shaft. make sure you let it cure for a few days at high temp (200 degrees F) before using the fan. 2. The seal between the plastic end cap and the metal motor housing is a high temperature adhesive which is very hard to breech. I used 2 screw drivers between the plastic end cap (see 2 small openings in the edge of the end cap) and the metal housing to pry and tear the adhesive. You got to be careful going in deeper than 1/4 inch because this is also the area where the brushes reside. It took me about 15 minutes to get it off without damaging anything. 3. The fan end bearing is staked into the metal housing (staked over the outer race). The only way to remove this bearing is to press the old one out using an arbor press. Then install the new one and carefully tack stake the outer rack of the bearing in place by using a very sharp small center punch on the metal housing OR just clean the mating metal surfaces real good with brake cleaner or contact cleaner and use Loctite Stud mount to mount the bearing in the housing. 4. The communicator end bearing is staked onto the armature shaft and will have to be remove using a miniature bearing puller. Do not try to pry it off or you will shift the commutator and maybe ruin the motor. Install the new bearing and stake the end of the shaft in 3 places with a very sharp center punch to secure the bearing." ---------------------------------------- Husky said he was going to check on the availability of suitable replacement bearings but I don't believe he ever posted that. You could try PM'ing him and see if has the info. |
