Rond Posted February 10, 2008 Share Posted February 10, 2008 I am new at blacksmithing-I purchased a Champion #40 Blower. I took the top off and cleaned out all of the old very stiff grease and dirt. It looks as if there are several set screws both inside and outside the blower. Is there a system to set these? After I cleaned it and put some 30 weight oil in it it seems hard to turn. It moves a lot of air but just seems pretty stiff to turn. When I quit cranking the blower stops immediately with no free run. Thanks Quote Link to comment Share on other sites More sharing options...

HWooldridge Posted February 10, 2008 Share Posted February 10, 2008 Pour the oil out into a container and see if it's easier to turn. Sometimes, the viscosity of the oil affects the turning speed. Many blowers only needed oil to the lowermost gear because it would carry it up and soak the rest - so too much oil is a bad thing. Quote Link to comment Share on other sites More sharing options...
jimmy seale Posted February 10, 2008 Share Posted February 10, 2008 on my blower the handle can be made longer to make it easer to turn. Quote Link to comment Share on other sites More sharing options...

I have seen the fan shaft get out of adjustment and cause the blades to 'drag. Oil seepage and dirt will sometimes create a buildup which will interfere with free travel of the fan. As far as the set screws are concerned, I try to leave them alone if at all possible.....I find them tedious to get set just right........but that's just me. Sometimes the oil or grease that's been in the gearbox for a long time is really caked hard.If it gets enmeshed in the gears, it can make turning the handle quite difficult. I would probably(if it were mine),empty the gearbox once again and use something like spray carburator cleaner to be sure all the 'gunk' was out.

Finnr Posted February 12, 2008 Share Posted February 12, 2008 A fill with ATF may do the trick. Dump the old oil fill with ATF, run the blower for a while and dump again. I use 10wt oil and MMO in mine and am real happy with how it works. Finnr Quote Link to comment Share on other sites More sharing options...
rthibeau Posted February 12, 2008 Share Posted February 12, 2008 The set screws are just to hold the gears and pieces in place, they do not effect the turning of the handle, etc. If you find it too hard to turn, you need to take it all apart and clean ALL the gunk out...maybe even let it soak in a solvent. When everything is really clean, reassemble. You don't have to press out the shafts on the main gears, WD40 will clean them. Light coat of oil will do to start after reassembly. See what happens.

welder19 Posted February 12, 2008 Share Posted February 12, 2008 If it is cold then the 30wt is too thick, use 10wt as mentioned above, also while there is no oil in it you can check to make sure there is no griding or binding while cranking. Good luck welder19 Quote Link to comment Share on other sites More sharing options...
stevomiller Posted February 13, 2008 Share Posted February 13, 2008 I have had good luck soaking them in diesel oil for a few weeks to loosen stuff up. The bushings/bearings are probably still gunked up and the new oil hasn't penetrated to them. I would also try the ATF route to see what happens.
