gadetoz Posted May 10, 2009 Share Posted May 10, 2009 Hi there, I recently acquired a Buffalo 625 hand crank forge blower. While it was working, it was noisy and I like to restore things to how the were. OK - so I stripped it down and the bottom two 'cone nuts' that adjust the open bearings which drive the fan are severely worn. Does anyone know if you can order replacement 'cone nuts' online (from Australia) - the other option is to start with a couple of nuts and turn them down - or pack more grease in. Thoughts, comments and advice welcomed. Trevor Link to comment Share on other sites More sharing options...
arftist Posted May 10, 2009 Share Posted May 10, 2009 Machine new ones, then lube with oil, not grease. Grease will trap grit which will contribute to future wear. Since this is a "total loss" system, oil it every day that you use it, twice if it is a long day. Link to comment Share on other sites More sharing options...

gadetoz Posted May 16, 2009 Author Share Posted May 16, 2009 Still searching, At this stage intend to order some bearings (6002-2RS, ID 15mm, OD 32mm, width 9mm) and pull out the open bearing cups. Will let you know how I go. Many thanks to those who have responded. Trevor Link to comment Share on other sites More sharing options...
gadetoz Posted May 30, 2009 Author Share Posted May 30, 2009 The sealed bearings 6002-2RS were no good. Ended up buying a M14-1mm thread die nut and re-cutting the thread on the shaft. Original thread was very close to this anyway as the original bearing cone nuts and lock nuts would screw nicely onto a M14-1mm bolt but an M14-1mm nut would not screw onto the original shaft thread. Anyway once the new thread was cut this enable me to use standard bicycle cone nuts. All good now running smooth and quiet. Trevor Link to comment Share on other sites More sharing options...
Ten Hammers Posted May 30, 2009 Share Posted May 30, 2009 Good on you for gettin fixed. You have re-installed some long ago thoughts in me about the use of bicycle parts. Many times the solution to the problem is just having another source of products to try. Link to comment Share on other sites More sharing options...
BlackSmithBear Posted August 2, 2009 Share Posted August 2, 2009 I have been using bicycle bearings to replace the loose ball bearings in my 400 blower, the ones you can find in a small bike with coaster brakes. Bear Link to comment Share on other sites More sharing options...
