Model #917881151 Craftsman snowthrower, gas

Question and Answers

Q:

My snowblower will not go into reverse when the control is set on reverse. 917881151 Craftsman Snow thrower

A:

Thank you for your question.

 

I am sorry you are having a problem with the snow blower. I recommend checking the unit in forward speeds. If the unit drives forward fine the belt and cable are fine. The problem is likely in the friction disc. For some reason the disc is not moving to the other side of the friction plate when it is shifted. I recommend tipping the unit onto its nose first. Then remove the access panel on the bottom of the blower. Once you have it removed watch the friction disc when you move the shifter from forward to reverse. The disc should move past the center of the friction plate to the other side. If it will not move to the other side, the shifter needs to be adjusted.

 

I hope this is helpful. Please let me know if you need further assistance.

 

Thank you for using Manage my life.

Q:

Craftsman snow blower #917881151 / engine #21C214-0553-E1: I am working on engine "throttle assembly", I see that the lever on carbarator will not move when

A:

Thank you for your question.

When the engine is turned off the throttle should be opened. A spring keeps it open. Then once the engine is started, the governor will regulate the engine speed. When you move the throttle, it changes the spring tension on the governor arm and changes the engine speed. You should be able to move the throttle plate on the carburetor. If it seems stuck, it might be gummed up from sitting. I recommend using carburetor cleaner to free it up. To confirm there is not any other problems I recommend pouring a small amount of gas into the throat of the carburetor then pull the starter rope. If the engine sputters or runs for a short time, I suspect the problem is carburetor related. I recommend cleaning or replacing the carburetor. Please let me know if you need further assistance.

Q:

How much grease should I put into the auger grease fittings?

A:

Thank you for your question.

I can understand wanting to know how much grease to put in the augers fittings.

I would suggest that you pull out the shear pins and then pump grease into the grease fitting a few pump of the grease gun and then spin the augers by hand to work the grease along the whole length of the auger shaft and then put in enough grease so you can see it just starting to come out between the auger and axle.

This will assure that the auger will not seize onto the axle shaft and then return the shear pins into place.

I hope this will help.
