wayne1967 Posted March 22, 2012 Share Posted March 22, 2012 I've tried the search but might be missing it, what is the jam nut large set screw to the right under the handle for? Quote Link to comment Share on other sites More sharing options...
cvmikeray Posted March 22, 2012 Share Posted March 22, 2012 Is it a 400 or a 40? On the 40's the nut at the bottom is for the gear used to take up the slop in the gears. Quote Link to comment Share on other sites More sharing options...

SReynolds Posted March 22, 2012 Share Posted March 22, 2012 What I did was to set that screw and locking nut to the point the shaft will turn with the weight of the handle. I'm not concerned with the end-play, rather the shaft must be free w/o any additional free play-end thrust-axial play. What-ever you wish to call it. These don't have bearings, so your simply adjusting the end-play between the shaft and the housing boss. I have also had to adjust the fan hub on the shaft. The one pictured had to be cleaned out as it was badly rusted due to water but still turned free. Then oiled, adjusted and a new wooden handle installed. It makes way too much air. A slow turn is all thats required. I see one is on e-bay auction now.http://www.ebay.com/...=item337370f4c5 Quote Link to comment Share on other sites More sharing options...
