How do I install brass bushings in a sproket bracket on QA-42A snow thrower for a cub cadet
Hello, How to replace the auger drive belts on a MTD,Yard Machine,and other two stage snow blower,that don't allow enough room to slide belts between the pulleys.
1.Tilt machine up on front end to remove the bottom frame cover,there should be six screws to remove,tilt back up right.
2.Remove the chute crank from the left handle and from the shoot.
3.Remove the black belt cover,there should be three screws.
4.Remove the support guide bracket,that the cable is running through,and remove cable end from idler pulley arm.(Note ,on some machines the pulley can be adjusted by loosing and move pulley towards the belt, than retighten.)
5.Remove belts from upper pulleys. (hint if there is a bolt holding the pulleys on it is easier to remove the bolt and slide the pulleys off to be able to remove the belts.)
6.Remove the six bolts and nuts holding the front half to the back half together,slide front part out to be able to remove old belts and install new belts. (hint make sure you get the new belt under the belt keeper on the bottom.)
7.Reassembly in reverse.
8.Set of two belts 0.312x34.75, part number 954-040B, $30.28
This first part is for replacing belts.
To remove the auger assembly completely follow these steps.
1.After removing the belts,and separating the two halves, remove the bolt holding the pulleys on,pay attention how bolt comes off and the way the washers are on be sure and put back on the way they come off.
2.Remove the pulleys and make note how they come off of the adapter pulley.remove pulley note how comes off.
3.Remove the bolts and nuts on the side of the housing.
4. Pull the auger out and place on work bench,making note how the end parts come off.
5.Remove the shear bolts to get and slide augers off, be sure and mark which way they turn as not put back on backwards.
6.You can access the auger gears by removing the bolts,to make repair.
7.also check the ball bearing in the rear housing where the auger shaft goes through to make sure it is not egg shape,if egg shaped needs replacing.will cause belts not to stay on and jump off the pulleys.
8.Check the end hex flange bearing (the plastic piece) to see if it is out of round,if is replace it.
9.Also you can download your manual if you don't have one depending on your model and number.and also you can check the shear pins in the augers if the above is not the problem.
hope this helps,,any comments welcome,thank you. @@
