Bearing part number?

[homebuilt]

does anyone have the part number for the needle bearing that would be used on the 30mm axle, maybe even the oil seal number. trying to put a set of 30 mm axles in a 122 rear.

thanks

Are you want the genuine Cub Cadet or Aftermarket numbers...???

either would be fine, if someone had them handy. thanks. I didn't realize that cub cadet used a needle bearing with the bigger axles. the rear I pulled these from used ball bearing's that had a od larger than the cast axle itself.

If you’re doing what I think you’re doing you may have a problem. You’ll notice that the flange that bolts to the trans case on the left side is much thinner than the right side for a 122. The late style stuff has a deep flange on both sides. Anyway the Cub part number for the bearing in the late style tubes is Cub Cadet 941-3033A. Pics are of the 122 & 1641 axle tubes. 1641 tubes are same as the rest of the Cyclops series that use the big ball bearings. You may want to download the Mid West Super Cub catalog http://midwestsupercub.net/MWSC2015.pdf then scroll down to page 17 and look at item # 38 they machine the tubes like what came on your 122 to take a larger bearing so you can use the 30MM axles.

My Son put 30 mm axles in his puller. The rear end was out of a 104 or 124 Cub Cadet. We bored the cast iron axle housings to accept a sleeved bushing/bearing. I don't remember where he got the bushings from.

thank you all. i'm not using the aluminum axle housing, just the axle shafts and the carrier. I've got a machinist's that's capable of opening up the cast housing's. I just need to get the needle bearings that will except a 30mm axle. this is going to be a work horse rather than a "puller" so I would prefer bearings over bushings. I just received a package from Midwest supercub with my new driveshaft/clutch/driver and 1066 fenders, included in the box was a handful of extras(thankyou) including a catalog. i'll flip through it and see if they have what i'm looking for.

The 3000 series use a needle roller bearing for their axles. It is a HK 3020.
It is
OD = 37mm
ID = 30mm
W = 20mm

Don't know if that will work or not, good luck.

We didn't use bearings or aluminum axle housings when we went to 30 mm axles on my Son's puller. Since I was the one that did the machining I felt the area where the bearing and seal went would have been too thin. Plans for my Son's puller is to move up to alcohol class in a few years.

Personally I think you don't need the 30 mm axles or diff for what you are planning to do. The only time you need the 30 mm axles is for an alcohol class pulling. Your 122 in stock form will handle any job around the house you can do. The 122 should have sleeve bearings in it.

I have a 100 that has a modified10 horse power engine and a stock trans-rear end. I haven't had a problem in 7 years and I not afraid to run the 100 hard.

It's your money......spend/waste it how every you want. I'm just trying to save you a few bucks.

Thanks oak, looks like what I was looking for. Merk, what do you think with a 16 horse v-twin. I already have a mwsc driveshaft and clutch. I'll have this thing weighted down heavy. It won't cost much more than th e bearings. Well except I guess I could sell the fine splines

How much weight are you planning to add?

Some IH Cub Cadets have a fine spline axles that would fit in by changing the diff and axles. Not sure what models the fine spline axles came in.

I have a 16 horse power V twin in an off topic tractor. The tractor has 1300 hours on it. The only problems were the starter and charging system. For me it has been a good engine.
