micro_meteor 14 #1 Posted December 13, 2019 Need input shaft bearing for chain side of input shaft. 42 " snow thrower Share this post Link to post Share on other sites
lynnmor 7,302 #2 Posted December 14, 2019 When you remove the bearing, you might be able to see a number on it. My guess, without knowing the model number of the snowblower, is that this one will fit. Toro wants a fortune for the same thing. Here is an old post to help you.

gwest_ca-(File Mod) 11,033 #3 Posted December 14, 2019 Early models of snowthrower used a 3/4" shaft and the common bearing available now has an OD that is not the same as the original bearing OD. What has been found is a 7/8" shaft bearing has the same OD as the original 3/4" bearing so they have been adding a 3/4"x7/8" bushing to the shaft to make it fit. Drill a hole in the bushing for the locking set screw. If it has the separate locking ring there is a hole in the side of it. That is so you can use a punch and hammer to rotate the collar in the direction of operating rotation and then tighten the set screw. This prevents the shaft from turning inside the bearing.

Herder 2,354 #4 Posted December 14, 2019 I purchased them from a Toro dealer sometime ago and yes the where expensive. Share this post Link to post Share on other sites
micro_meteor 14 #5 Posted December 14, 2019 Thanks for the quick reply, I found 2 for sale on eBay with several pix and at a reasonable price. I didn't expect that! Mike Share this post Link to post Share on other sites
mowerman1193 32 #6 Posted January 3, 2020 Just run across this topic.. I've got one of the early ones apparently as I have a 3/4 shaft and a outside diameter bearing the same as a 7/8" flange bearing.. took it to match it up at the local bearing shop and they couldn't help me as you say.. What I'm kinda wondering is.... My shaft is worn so it also needs replaced.. I'm not sure I'm reading this right but are all the shafts 3./4" or were some 7/8" or is it just the bearings that they made a odd set up for.. I guess I need to know what shaft to buy if i gotta replace it.. maybe better to go to a 7/8 shaft if that was a option on some? so then I could use the standard bearings.. This thread kinda got me confused now.. I was hoping to maybe find a machine shop to cut the key slot out in the shaft and maybe make my own.. since I know a few machinist that probably would do it for a couple drinks.. looking at the parts for them it appears the shaft is nearly $200 + or - depending on where you shop.. so any advice on this from those that know more than I do is welcome. and appreciated .

vanillaman 10 #7 Posted January 3, 2020 I found mine on Amazon 1 year ago. Look for Peer bearing FHS205 - 12G insert bearing. They cost me $23.45. I don't know how add a link to this for you. I also found the sprockets that I needed at a resonable price. Dick (aka vanillaman) Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,033 #8 Posted January 4, 2020 The shaft size changed in 1987. Front quick hitch introduced. Snowthrower rear frame has a 5/8" diameter round bar. 1973-74 model 6-6212 plus 6-9113 1974 model 6-6213 - (First model to include 8-0221 extensions without the front straight return - just a flat plate) 1975 model 6-6214 - (First model to include 8-0221 [103552 replaced by 93-1617 and 93-1617-01] side extensions with the front straight return. First model to have a cable spool on chute rotating crank) 1976 model 6-6215 - This one - 1976 model 66-42ST01 - and this one are likely identical. The model number format changed. 1977 model 76-42ST01 - This one 1978 model 86-42ST01 - and this one 1979 model 96-42ST01 - and this one plus 1980 may be all the same. They started using a different model number for each model year. 1980 model 06-42ST01 - (Last 42" model to use 4 grooved rollers for the chute) 1981-82 model 06-42ST02 - (First model to use plastic collar for the chute but was a retrofit for older models. Last model to use wheels) 1983 model 06-42ST03 - (First model to use skids) 1984-87 model 06-42ST04 - (Last model to use a 3/4" diameter driveshaft) 1987-89 model 06-42ST05 - (First model to use a 7/8" diameter driveshaft) 1990 model 06-42ST06 - (Last model to use a cable to turn the chute) 1991-93 model 06-42ST07 - (First model with tall chute retained by 3 individual grooved retainers) 1993-2001 model 79360 - (2001 and earlier will fit 2002-2007 with kit 105-1503) 2002-2007 model 79362 You will also need to change the sprocket on the left and the pulley on the right. I used 7/8" shaft with a continuous keyway before I learned this was done at the factory. https://www.princessauto.com/en/detail/7-8-in-x-3-ft-keyed-shaft/A-p8079741e Also changed the style of bearing. https://www.princessauto.com/en/detail/4-bolt-7-8-in-standard-duty-flange-mount-bearing-assembly/A-p3870041e Made my own sprocket with a different number of teeth than the original - can't remember how many but wanted to slow down the auger https://www.princessauto.com/en/detail/14-teeth-40-chain-weld-on-sprocket/A-p3844545e Sprocket welds to hub https://www.princessauto.com/en/detail/7-8-in-bore-v-series-weld-on-hub/A-p3845120e Used the largest pulley that would fit to slow the auger down. Forget the diameter but these use the same hub as above https://www.princessauto.com/en/detail/5-1-2-in-weld-on-pulley/A-p8033771e I used a cast iron pulley with the tapered bushing to fit the shaft. Forget what diameter I used. https://www.princessauto.com/en/detail/5-75-in-solid-cast-iron-sheave/A-p8046104e https://www.princessauto.com/en/detail/7-8-in-bore-split-tapered-bushing/A-p8069528e Original bearings mounted with 3 bolts and the 4-bolt required the shaft to be moved to the rear a bit which allowed for a larger pulley that I wanted for slowing the auger down. Total was a fraction of the Toro cost. Garry 1 Share this post Link to post Share on other sites

Mowerman, That's how MINE was made a few years ago. I went with 3/4". Mike aka micro meteor 1 Share this post Link to post Share on other sites
mowerman1193 32 #10 Posted January 5, 2020 I think what I'm going to do with mine is wait until i take the other end apart and see what shape the gear and bearing etc is on the other end.. If they are worn bad enough to be needing replacement.. I'm thinking I might order the 7/8 shaft and gear etc and make it as though it's a newer model blower with the 7/8 shaft..This way if I ever need to dig into it again.. I can just get the standard 7/8 bearings Share this post Link to post Share on other sites
