utaholdiron Posted February 28, 2011 Share Posted February 28, 2011 I was attempting to dismantle the gears, but came across a tiny bolt whose head was broken off. This particular bolt, when tightened, holds the largest blower gear to its shaft (axle). I can go no further till I figure out how the xxxx to loosen this tiny bolt. Any help would be greatly appreciated. I don't believe it's possible to use a "screw extractor" because of the close confines. Also, drilling out the broken bolt is not feasible for that same reason. I'm enclosing several pictures. Quote Link to comment Share on other sites More sharing options...

How the drilling and tapping was done in such a small, tight space is beyond me. I have a welder friend, I'll see if he can do as you suggested. Thanks for the info.

Andrew Y Posted March 8, 2011 Share Posted March 8, 2011 I rebuilt a Buffalo blower that looks identical to yours. The large gear on mine was not held in place by a screw. It had a taper pin that secured the gear to the shaft. I suspect yours is the same. Quote Link to comment Share on other sites More sharing options...
Jason @ MacTalis Ironworks Posted October 7, 2011 Share Posted October 7, 2011 Just pulled mine apart, and was also a taper pin... use a pin drift to knock it out. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted October 7, 2011 Share Posted October 7, 2011 Since blowers tend to "wear into" their gears. Taking them all apart can result in a blower that runs *worse* afterwards than before. Did you mark each gear as to it's exact mesh? Quote Link to comment Share on other sites More sharing options...
Wesley Chambers Posted October 16, 2011 Share Posted October 16, 2011 Tom what brands have you found this issue? I have done a rebuild/service on about 5 buffalo and 3 champions with the end result always better than the start, granted this is only a small number.

ThomasPowers Posted October 17, 2011 Share Posted October 17, 2011 I don't recall as that was about 25 years ago. I just remember that they ran a bit noisier after the clean up than before. Quote Link to comment Share on other sites More sharing options...
