Tacey 0 Posted December 23, 2007 I need a pic of the proper S/G on my 3410 (10 Hp briggs single # 234341, I think). My S/G belt is slipping, and as I tried to tightening it, I noticed that the adjustable brace used to adjust the belt tension doesn't look right. I'm still getting used to my "new" 3410, and ironing out bugs. I have been using it to plow snow, and haul a TON of firewood, and it runs great. I've looked and looked and searched for a line-drawing or a photo, and I'm stumped. (Doesn't take much - - ha). Thanks. Tacey Share this post Link to post Share on other sites
D-17_Dave 12 Posted December 23, 2007 A common problem is the tensioning bracket, (item 12) on Maynard's picture, is sometimes reversed. This makes the bracket hit the mount and won't let the belt adjust completely. May not be your problem, but I thought I'd throw it out there anyway. Share this post Link to post Share on other sites
PhanDad 3,456 Posted December 23, 2007 Another reason I've experienced for belt slipping (only on starting - never on running) is an old belt. The belt develops a "glaze" as it hardens with age and just doesn't grip well. Since you have to unbolt the driveshaft to change the belt, I never get around to changing the belt in the summer - always when it's cold and the belt slips even more.

Tacey 0 Posted December 23, 2007 Thanks for the drawing UCD, and for the words of wisdom D-17 Dave and PhanDad. It looks like I have all the right pieces. The piece that I was describing, part # 12 (the Tensioning Bracket), looks to be the correct one. The thing just seems to be an awkward design; I would think that a curved piece would be easier to adjust. The bolt that I have ( item #9 in the drawing) is not the right one. It looks too small and too short. I'll replace it and adjust. I also will try cleaning the belt, because I may have gotten some WD-40 or something on it when I was cleaning up the tractor. Thanks again, and I'll let you know if when I get it fixed. d:) Tacey Share this post Link to post Share on other sites
JimDk 0 Posted December 23, 2007 Randy, Your S/G pulley may be worn. I had one that the groove was more "U" shaped than "V". No amount of tightening helped. I had to change it. Share this post Link to post Share on other sites
D-17_Dave 12 Posted December 23, 2007 If the bolt the joins the bracket to the generator is loosened a little so it can hinge freely it will slide and work as easy as a curved bracket. Also a worn belt that must be over tensioned will decrease the bearing life of both the generator and the engine. Share this post Link to post Share on other sites
Tacey 0 Posted December 23, 2007 Ok, I got it tight, and the tractor now starts right up almost instantly. You guys have me thinking it might be a good idea to change the belt. It does seem to be pretty slick. I'm going to price a new belt and a pulley. I'm sure that would be an easier and cheaper fix than new bearings.

JimDk 0 Posted December 23, 2007 As I recall, the pulley was very pricey. I scrounged up a good used one. Good Luck and Merry Christmas, Jim Share this post Link to post Share on other sites
olcowhand 0 Posted December 23, 2007 Lots of times the belt is worn on the sides to where the belt's bottom hits the bottom of the pulley where it gets little traction. Sounds like you definitely need a new belt. Less than $10 and a good investment! Share this post Link to post Share on other sites
