Colt Case Ingersoll Garden Tractors

Pulling out the auger revealed on one side the wrong bearing type and on the other a very worn off bearing.



Clearly new bearings are needed. A package arrived yesterday with these inside



I've been following the snowcaster mod thread. Much as I'd like to modify the chain tension mechanism as you guys suggested, a project like that can't be accommodated at the moment.

I must say, Case Ingersoll using all these non-standard bearings reminds me of Apple and their proprietary connection ports over the years. Don't shoot!

JD is worse.

Had a little time the other day and thought I go install the new bearings.




Oops! My bearing shrank?! When I had another look around I found out that these bearings need a sleeve! The bearings that don't need the sleeve are the RX-84! ok fine, let's not panic. Unfortunately, one sleeve costs around $70US, plus shipping and brokerage. How's that for fun?

Thought I might as well order the RX-84 and call it a day. But then the nice Fafnir 204KRR2 that I got are just wasted, and that bothers me. On top of that the one vendor that I wanted to get the RX-84 from does not carry them.

Plan B. Turn a sleeve on the lathe. Hm.. but I don't have pipe or rod stock that size: 2-1/8 OD and 1.86" ID. Then I thought, why don't I use the outer race of the old bearing. All I need is to take some material off the interior side. You should see the sparks flying on the lathe. That bearing race is hardened steel!

Fine! What does to soften steel?




Yep. That bearing race was a pleasure to bring to size on the lathe after it got cold.




Problem solved.

It seem that both Dave and I are doing a snow caster refresh/rebuild. Mine is functional with the old bearings but loud like crazy. From the little investigation I did so far, it seems that these are the bearings for my old (70s) snow caster.

Auger bearing: type RX84.


This bearing is also known as:
ZORO: G3800161
Roberts: RX68
Case: C29265
Case: C29264
Airens: 054111

DIMENSIONS:
BORE: 11/16" Hex
O.D. Outside Flange of 2.25" and Outside of Bearing Surface of 2.125"
IR Width: 0.80"
OR Width: 0.625"

One can also use the Fafnir 204KRR2 bearings with 47mm OD, but it needs a sleeve because the auger ID is about 54mm.


Jackshaft bearings. Seems to me the original have the Fafnir 42LST flangettes, indicating a bearing with 42mm OD. I could not find any bearing like that. It also seems that this kit is what our Case parts vendors are selling to replace the original. The kit seems to have the 47MST flangettes, which are (surprise! ) housing a 47mm bearing, the SA204-12. Here's the link to one of the vendors kit, which even includes instructions on how to "make the hole bigger!" cool

Here are dimensions for something like this from a different online source.



It's the line for 3/4 ID that we're interested in. Shows it's using the 47MST flangette/housing. And the SB204-12 bearing. Don't know the difference between the SA204-12 and SB204-12 bearings.

the difference between the SA204-12 and SB204-12

is the SA has locking collar and SB has set screws . The same number with a C in front of it is cylindrical not self aligning.


Dave

Thanks @DavidBarkey , but I don't get what locking collar is. I think set screws are just a couple of screws that fixes the collar to the shaft.

Dave

Never mind, I found examples of locking collar bearings. They lock with a mechanism that isn't as likely to damage the shaft like set screws.
