36" snowblower help

You say you loosened the 2 set screws. Were 2 set screws on each bearing? If so, you have the newer style bearing and after loosening, the bearing should slide on the auger shaft allowing you to remove entire auger assembly from the blower housing. For reference, see my post for pics of the new style bearing and the issue I had with locking the bearings in place, you can see how they slide: http://www.simpletractors.com/club2/topic.asp?TOPIC_ID=115201&SearchTerms=snow But if your blower has the original bearings, they only have 1 set screw per bearing. The original bearing is eccentric as mentioned in the post above. After the set screw is loosened, you use a drift in the "extra" hole to rotate the eccentric part of the bearing to loosen it from the shaft. I bought the old style bearings to replace the new style. I'll try to take a pic of them and post later.

Thanks for the replies.Getting somewhere now.Used some small prybars and pried the inner flange outward and the bearing came along with it.It has two setscrews.The outer surface is rounded over to perfectly mate with the flanges when bolted up tight.I found this bearing at MC but it is not rounded over-looks flat,but the width is ok at 5/8" and fits a 1" shaft.Wonder if it would still work? http://www.mcmaster.com/#standard-ball-and-roller-bearings/=ecytfu Don't think a direct link will work.The bearing I took out is a Roberts MFG SBF-16.

Here's a pic of the bearing.Guess I'll have to try to get the correct model thru a dealer.Can't seem to find a match with that ouside contour.Might have to blow it up some to see the contour.Also,this has a groove with no obvious function that I can see.

Pics of the original style bearing:

Bearing with eccentrics not lined up:


"Inside" the two parts of the bearing where the eccentric cuts can be easily seen:


This bearing is shielded (sealed?), but greasable. The only difference that I can see between this bearing and the non-greasable new type(double set screw) are two small holes in the outer race. One of the holes can be seen in the second pic. I had a hard time finding the greasable bearing. It's no longer available from Simplicity. The non-greasable one (Fafnir RA100RRB + COL) is easy to find - my local autoparts store could get it for me. I found the greasable type on eBay (old stock).

Bill,thanks for the pics and info on the bearings.Here's a couple pics of the sprockets.The chain is a little loose and the shaft is all the way back in the center slot.Don't know if a link could be removed or not.The chain looks ok,but the small sprocket looks the most worn of all the related parts.Is there a rule of thumb on "past prime" condition of a sprocket?

I'll make an observation at this point.This blower appeared to be in good shape and had been taken care of,lubed properly and so on,and not banged up.But,it's 40+ years old and everything that "moves" needs replaced to return this thing to a reasonable expectation of useability.I'll probably have 200-300 in parts and paint to restore it.OTOH,when I'm finished it'll probably go another 40:)

The bearings are common ag flange bearing that you should be able to get at any farm store for about $8.00 a piece and while you're there you can pick up a length of roller chain for maybe $10.00. Sprockets don't look that bad.

Thanks for the tip.Picked up two at Rural King for 7.99ea.They're the eccentric type.Any tips to install these?
