Snow thrower wheel drive problem
I have a fairly new Sears Craftsman (Murray) snow blower. The unit
itself works fine, but I am having trouble with pin that unlocks the right wheel for easier maneuvering on dry ground and locks it for both wheel drive. According to the directions the "klick pin" can be moved to the outer hole to unlock the right wheel so it is free wheeling. In the inner hole, the wheel is connected to the drive axle so that it is driven together with the left wheel. This worked great for a few times. Now I have the pin in the free wheel (outer) hole and would like to put it back in the drive (inner) hole. Unfortunately I can only see the exterior part of the hole. I can no longer see all the way through the hole, that goes through the axle. The pin must go all the way through this and something appars to be blocking it. Has anybody had this problem? How do I fix it and get everything to line up? Thanks. [ Sears Craftsman Murray snow blower snow thrower klik pin click pin klick pin 881750 536.881750] |

The outside hole is 90deg from the internal hole. I had a hunk of ice in mine. Blasted it with a heat gun, budda-bing, was cleared in about 30 seconds. outside | ------- inside | -Brian |

My problem isn't ice though, my unit is warm and dry in the garage and the inside (axle) part of the inner hole is obscured by something. Is there any chance a bushing or something has slid in the way? I'm reluctant to take the wheel off and I'm not sure the retainer ring could be used again. |

I had this exact same problem.
There is a nylon bushing inside the wheel 'hub' that has slid out of place. It acts as the bearing between the wheel rim and the axel. Prop that side of the blower up and pull the wheel right off. (Mine had a star shapped clip I had to pry off with a screwdriver before I could get the wheel off.) The nylon tube may stay on the axel shaft or you may have to push it out of the wheel. Put the bushing back in the wheel, aligning the holes and drop the pin in so they stay ligned up. Put the wheel back on the axel untill the pin hits. Pull the pin almost all the way out and put the wheel on. You want the pin through one half of the wheel and and one half of the bushing so the holes stay lined up or you'll be pulling the wheel off again. The wheel slides on and off real easy. I did this on a Sears 536.887752.. There are no bearings or other pieces that could fall out. I see this as a design flaw and I leave the wheel locked all the time. Good Luck |

I did this on a Sears 536.887752.. There are no bearings or other pieces that could fall out. I see this as a design flaw and I leave the wheel locked all the time. I was able to fix the problem by taking the wheel off. That was simple, but getting the retainer ring (clip) off before the wheel was a real pain, even with a screw driver. My bushing doesn't have holes in it, it sounds like yours does? I just moved the bushing farther down the axle so it isn't covering the 2 wheel drive hole anymore. I need one wheel drive to store the machine in the garage, but I'll be sure not to use it other than moving the blower in and out. I was trying to think of a way to keep that bushing from moving, perhaps a small screw (extending no further than the thickness of the bushing) in the axle will do it. I don't have a drill press available to do that though, so I'll just hope it doesn't wander around again. Thanks to all who responded! |
