Q:

Craftsman 9 HP Snow Thrower 536.887993 Gear Case 536.887993 Mfd 2003.10.11

A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the issue you've had with the auger not turning. I know how frustrating that is.

If the impeller is turning, you know the belt is fine. First check the shear pins in the auger shaft. If they are sheared, the augers will not turn. If the shear bolts are still intact, the problem is a sheared worm gear in the auger gearbox. Removing the auger assembly on a snow blower is not an easy repair that is usually done by a service technician. If you decide to repair the blower yourself, please follow the steps below.

Remove the spark plug wire and belt cover.

Disconnect the chute control rod.

Remove the belt and the auger control cable if it is attached to the blower head.

Locate and remove the bolts that attach the blower head to the drive assembly.

Once the blower head is removed tip it onto the nose so the pulley is up.

Remove the pulley from the shaft. It should have a set screw on the backside, maybe two. I recommend spraying the shaft and pulley with a penetrating oil to help with removal. I have seen in some cases a puller is needed to remove the pulley because of rust.

Once the pulley is removed you can remove the bolts securing the bearing. Then slide the bearing off the shaft. This can be difficult to do if the shaft is rusted. I recommend cleaning the shaft with emery cloth before trying to move the bearing. You might also need to use a puller here also.

Remove the bolts securing the bearing for the left and right auger shaft. Then slide the whole assembly out of the blower housing.

Remove the shear bolts and remove the augers. Make sure to mark the augers left and right so you do not get them mixed up. If they are reversed, the snow will not be pulled into the impeller. Most of the time, I find the augers are rusted to the shaft so you might need to spray it down with penetrating oil and let it sit overnight. If they do not come off you may have to heat them up to break then loose.

Once the augers are removed you can split the gear case and replace the auger shaft. Make sure to clean all the old grease out of the case and repack it with high quality grease.

I hope this helps and thanks for using SearsPartsDirect.com. We appreciate your business.

Thank you very much for all your help and advice. Do you have a preference on gear grease brand and should we also order a gear case seal as well? I love your car, I had one the exact same color, it was a present from my parents for graduating from High School. I helped my dad rebuild it (I'm his daughter). Regards, Jamie Teague

Q:

Can I add a light kit to my Craftsman snow blower model 536.887993?

A:

You are correct the engine has an alternator but we do not have a light kit listed for your model. The manual does not state what the voltage is coming out of the alternator. It is possible to be ac or dc voltage. Any addition of a light kit is going to be a retrofit and we do not have instructions for them. I wish I could have been more of a help to you.

According to some internet research the alternator used in this snow blower is PART NUMBER: 611111. This is an 18 watt, 12 volt coil. Therefore if you were to connect a light to it, it would have to be a 12V bulb, and consume less than 18 watts total power. Because there is only one wire coming out of the alternator, I would assume that it is the (+) side, and the other end just ground to the engine. On a DC application it does not matter what lead is connected to (+) or (-) for a light. Sears did offer a light kit for another model that you might be able to retrofit with some modifications. Here is the link to the kit for the other snowblower. http://www.searspartsdirect.com/partsdirect/part-model/Craftsman-Parts/Snow-removal-equipment-Parts/Model-768884900/0247/1507100/00042358/00007 If you are handy, I would recommend visiting a local auto parts store or Radio Shack and see what they have. Most of their lights will be 12V. I would also like to add a light kit, and I will probably use an LED light as I can get a brighter light, and use less power.

Hello to all. As stated above the coil produces 12V at 18 watts, shich is 12V at 1.8 amps. Here is a link for a light that I've used on my snow blower. It's a 12v LED light that draws only 343mA or about 1/3 amp, which will not overload the lighting coil on the engine. Herre's the link from Norther Tool: http://www.northerntool.com/shop/tools/product_200616639_200616639 This only contains the light, you will need to install a fuse, an off/on switch and wiring. Hope this helps. Lewis.
