As for straddling that driveshaft, I guess the tunnel cover would protect your essential parts...

The tractor was repowered with a 16bs and I have been making a lot of decisions for new parts as lots I have come across is not stock. Johnny cash would be proud as this thing has come one piece at a time! Lots from the shop after hours. Didn't think I could one up the time tested engineering(learned that while rebuilding an old 8x8argo) , just got caught making a potential mistake. I will get a mounted bearing in there to support the shaft. Coupler specs out to be able to take quite a pounding so I am comfortable there as far as wood chipping.

Thanks for the input! my twins appreciate it

941-3004 Self aligning ball bushing....... $23.75
722-3000 Flex disk coupling..................$13.22
IH-547749-R2 Hydro cooling fan...........$10.73
Shipping.......................................... ...$13.00

Total............................................. .....$60.70

Knowing that the driveshaft isn't going to explode and hurt you........... priceless.


By the time you buy a pillow block bearing and install it you could have fixed it right, for less money and half the time. I strongly suggest, for your safety, that you take off your "repair" and shelf the parts. Buy the correct ones, and start over.

Sounds good. Thanks for the part numerbs. Get those parts from the cub dealer?

Tractor is coming apart this winter for blast and paint, repair some worn linkage, etc. I have one more mowing to do and a couple gardens to till. I think my repair will hold up. I am putting the keeper in there for the little work I have left just in case.

It is getting cold out and new garage needs insulation and heat. I will post pics this winter of the resto work AND the OE drive line parts.

You can get those parts from the dealer yes. I look up part numbers here: partstree.com. I got the prices by plugging the part numbers into this site: cubcadetpartsandmore. It seems to be the place with the best price.

Now, I see a U-joint at the front. If it is rated for 3600 RPM, it will be ok..... but, I thought you said something about a B&S engine in this tractor. I don't know what motor you have, but that is also not factory (motor or u-joint). I suggest talking with JeffinPA and getting a new driveshaft made. Check out his stuff, here, and if you need a custom shaft, Jeff will gladly work with you. (Post #6 is his driveshaft post)
