42 snowthrower spring location

Recommended Posts

landlord2110
I bought a used 42" Simplicity snowthrower and there is a sring that was loose and would like to know where it hooks up on both ends. there is a drawing on simple tractor web site 36"(2025057) showing that same spring but cant tell where attaches. it is item # 4(spring,return) on drawing.

It's the "return spring" for the movable idler that moves it up when you release the clutch engagement rod... one end fastens to the bolt that holds that idler pulley (between a set of double nuts) and the other end fastens over a notch in the snowblower hitch frame as shown below: [img]http://www.simpletractors.com/images/snow_ops/figure_5_small.jpg[[/img] I don't see a picture that shows the other side of the idler, with the double nuts on the shaft, but here's a view that shows the bolt from the other side: [img]http://www.simpletractors.com/images/snow_ops/figure_4_small.jpg[/img] Here's the operation manual for the similar 36" blower, that goes along with the parts manual you found, also on Simple trACtors: http://www.simpletractors.com/operation/snow_thrower/single_belt.htm

Not sure of the cause of the need too do so, but when I moved that spring from the notch to the left side of the bend in the hitch frame I quit eatting belts. I know its because of the way it pulls on the pulley, alining it better, I just haven't figured out what tweeted to cause the need.

Marty, Check the little pulley brackets........ They bend. Moving the spring compensates for a while until the brackets bend more.

Yea, they do do that Herb, I've hammered them straight so many times I think the metal is getting weak. Never have known just what angle the rods they mount on are suppose to be, when I got mine they been rewelded already, I just try too keep the pulleys running straight with the belt. Maybe I should restrick myself to just using it on the driveway.

Welding a small "strong back" to the side of the bracket(s) will cure the repeated bending.
