Hi all,
I recently acquired a new in box Kirby Heritage II, which I had some concerns about the condition of it's bearings prior to receiving it. When I first got it out of the box, the motor shaft did not spin very freely at all. Now having about 10 hours on the motor, the bearings have started to emit a bit of a whine. I also don't feel like the motor is spinning as freely as it should. I had hoped I would not have to resort to a bearing change, but I want to make sure the machine is in perfect running order. I placed an order today for the below parts. While I am at it, I'm also going to change out the brushroll to the new version with ball bearing ends, saving the original one along with the original belt from 1986! I'm going to photograph and create a pretty straight forward guide, complete with excerpts from the Kirby Heritage II Service Manual, and will share it as a word document with the group. In the video at about 3:15 you can hear the bearings are starting to emit a whine, which has gotten worse. New bearings are in order :) Order Invoice: Kirby Front Bearing fits Classic Omega To New Sentria $6.00 Kirby Rear Motor Bearing fits Classic Omega / SE $6.00 Kirby Mylar Front Bearing Seal and Retainer $2.50 T130 Fan Locking Tool for use on 1CB through LII $2.25 Kirby 4 Row Brush Roll 16" w/ magnet and Ball Bearings $19.76 Parts order courtesy of Kent Oyler cleaner48 on eBay where I get all of my Kirby parts from. Highly recommend him! http://myworld.ebay.com/cleaner48/... I already have a Kirby rear bearing puller in my stash, as well as fan case sealant. Andrew ![]() |

David,
Problem is with the carbon brush theory it's getting louder and worse with use. I've put another 5 hours or so on the machine and it's getting worse so I'm sure the bearings are dry. Also the motor is stiff to turn after it's been shut off for several hours after being used, just like it was when I took it out of the box. The grease inside the ball bearings must have lost some of it's properties after sitting all those years. Easy fix for me and inexpensive as well considering Kirby parts are very affordable. Andrew |
