older mtd snowblower

Hello, have an older mdt craftsman and the impeller blade assembly has broken off the impeller shaft. I'm trying to remove the auger assy. and shaft. The impeller has two roll pins which I removed. Is trying to get the auger assy and shaft out a ' heat and beat ' situation or is there something holding the shaft behind the impeller? Any advice appreciated.

Oxy acetylene and a good press will usually do the trick. You may, however, elect to just replace both parts to save yourself the trouble or the possibility of warping the impeller fan and bending the impeller shaft. They're generally not too cost prohibitive to do this. Post back with your chassis' model and serial numbers and i'll give you some dollar figures.

Hello,
Thanks for responding. The model # is 247.885570 on the site www3.sears it lists the impeller as unavailable. I was hoping to somehow pull it off and mig the blades back onto the impeller shaft. Have been trying with map gas but guess I have to go hotter.

I checked with MTD and yes the impeller is discontinued. Your snowblower is a 1997 model. You have 10 years worth of rust. Mapp gas will NOT do it. If you have the assembly off, take it to your favorite auto shop that has oxy/acetalyne and a press. This is about the only way to get it off without ruining it. Then take it to get it mig welded.

Thanks Indy,
Yeah, was given to me a couple of years ago. I'll get some tanks and see what I can do. Appreciate the info.

Back to a previous question. Should the auger assy. and the shaft with the impeller on it pull out as a unit when I remove the auger end plates?

After you remove the drive pulley than yes the auger assy. will pull out as a unit.
