snowblower bearings

[matt monte 132]

did a search, didn't find anything. gonna start messing with this next week, picked it up for my 312-8. 1st off i noticed slop in this bearing. Not sure pn. is there any manual on how to replace? the sticker is very worn-out so im at a loss on how to correctly identify

[matt monte 132]

also i know this sounds stupid but how do you spool the wire to the snow shoot? keeps binding up

The model you have likely is on this list

Snowthrower DNA

All have 2 idler sprockets for the drive chain. Started out as 37" wide and the added wings make them 42" wide.

1966-67 model ST-376

1968 model 6-1211

1969 6-6211 plus 6-9111

1970-72 model 6-6212 plus 6-9112

All without front quick hitch so not a direct fit for 1973 and later tractors. Snowthrower rear frame mounts in the front of the tractor frame using 2 bushings and a long 3/8-16 x 8-1/2" bolt.

------------------------------------------------------------------------------------------------------------

Front quick hitch introduced in 1973. 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) Chute crank support decal 104461.

1976 model 6-6215 ------ Chute crank support decal 104461. This one -

1976 model 66-42ST01 - Chute crank support decal 104461. and this one are likely identical. The model number format changed.

1977 model 76-42ST01 - Chute crank support decal 104461. This one

1978 model 86-42ST01 - Chute crank support decal 104461. and this one

1979 model 96-42ST01 - Chute crank support decal 104461. and this one 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) (1994 first year for replaceable blower housing scraper bar)

2002-2007 model 79362

 

One difference in models is what the cable is wound around - the crank or a spool on the crank.

Does the chute turn in 4 grooved rollers?

Tractor Supply usually stocks them, on shelf item, just bring old one with you & compare.

If you pul the pulley off the shaft, that bearing should be able to follow.

@matt monte  do yourself  a favor , look up flange bearings , for a probable match up , with that solid base go to , you might even  switch to a 4 bolt  flange , critical  to this is hi temp grease lubrication at every movement point . lucas  red /  or prefered green grease . make every rotating  point easy / smooth to function , also detail in your chain drive auger set up , use specific , chain /  cable lubricant  , never let it dry out / rust , my  36x42  single stage spins up by hand ,  12 hp  runs that  without effort , pete

I recall there being a problem finding a bearing with the correct OD and ID.

The 3/4" ID bearings usually have a 7/8" OD.

What they were doing is using the 7/8" ID bearing with a 7/8" x 3/4" bushing to fit the 3/4" shaft.

@gwest_ca  agree with that , finding  a matching bronze bushing is easy for fit assist , notice there is no mention of the grade or type of lubricant used in those bearings ?  you assume   that its the right stuff , with the continuous  bearing failures /  load dragging  on attachments . ever wonder why so many members are burning out pto , drive clutches ?  kind of like dragging a sled , you can make it better ,  pete

Since a snowblower operates in a cold environment with plenty of water and ice, I would think that a marine grease would be the best choice if one wants to open a sealed bearing for grease replacement.

@matt monte  agree with the  marine grease  , also has a very extended range of protection.  temp amd durability , those  needle point grease  tips , are also very good  in tight spots . when I  fist installed my  snowblower years ago , used , neglected . was amazed that  it worked at all , their was so much collective drag  on it . just broke it down for function , kept gaining on it , up for sale now , it easily spins by hand , no screaming  shuddering attempt to function , it just  works like it should , done that on all my related  problems ,  go grease , pete

thanks for all the responses. im gonna mock it up 1st then i will attempt to run it. ill post a better pic, using list i was able to figure out missing digit.  0642ST04.
