The Lexan fans only last a couple of years from what I've heard. The centrifugal force and heat weaken them. Not to mention they usually suffer when you suck something up that's too hard. The newer yellow plastic fans that started with the G5 are much better! I replace all my Lexan fans with these. Much better!!!

The new fans are not lexan they are amodel.
Replacing the fan is not that hard. You need to get the fan case apart then look inside the motor housing by the motor fan to find the hole in the armature and put an ice pick or tool in the hole to lock the armature. Then take another tool to place in the hole on the belt pully and turn the pully clockwise to take it off. Slide off the old fan and the adapter behind it. Place the new metal adapter on the shaft then the fan then the washer and finally the new pully. Stick something in the hole of the pully and turn counterclockwise to tighten. | ||

I thought the newer fans were made of Kevlar. That's what most of the replacement fans I see advertised online are advertised as being made of. Looking at the data sheet, Amodel seems to be a pretty impressive plastic also.

To Bikerray, Thanks very much , it does seem rather easy, and I would save some money. What type of sealant is recomended for resealing the fan case to the motor unit? | ||

 The new fans are made of a new polymer called Amodel. There was never a Kevlar fan. The fans were originally metal then were switched to Lexan which proved to be a disaster as they lasted only a few years. Finally Kirby worked closely with NASA to design the new Amodel fan. Check out this link to find out how Kirby and NASA worked together to create the new fan. CLICK HERE TO GO TO sptyks's LINK | ||
