Bent auger on single stage mtd

Hello,

I have a single stage yard machines (mtd) snowblower (4.5hp,21 in.) that has a bent auger. I was wondering if i could use the auger off an older mtd machine (3hp 21 in.). It looks about the same.

The model number of my blower is
31AE150-129
and the part number of the auger assembly is
784-5485

The model number of the parts machine is
315-140-000
However the manual from the mtd site did not give good parts list, just the wear items.

Can I use the auger off the other machine?

Thanks

Both model numbers you give use the same 784-5485 auger.

Thanks Airman.


I can't seem to get the auger off the parts blower.

Here are a few pictures of it

I got the side with just the bearing off, however I cant get the auger pully off. Im not quite sure how it comes off. It has a 1" nut on it and it appears to be on a threaded shaft. I tried turning the pully counterclockwise with a big wrench on the 1" nut while keeping the auger from rotating. I have moved it a little over half a turn but the threaded shaft that the pully is on is turning with it, and its not getting any easier to turn. Is this threaded shaft the the end of the auger shaft, or something that screws into it?

Does anyone know how to get this auger off?

Thanks.

Could be a left handed thread. I have come across a couple but do not remember if it was an MTD. There should be nothing else holding it on

smallengineguy is probably correct. The service manual for the 200 series shows a left hand thread.

Wouldn't it be nice if left hand threaded fasteners had a marking to identify them.

fixed

Well, I changed the auger and repacked the auger bearings. It works a lot better now. The threads on the both of the auger/pulleys were left handed.

Thanks Airman and smallengineguy.
