1A tiller seized up, need help!
 

Hey all, I am new to Cub Cadets and small tractors in general. I have a Cub Cadet 123 with a 1A tiller. The tiller was running and then suddenly seized up. There are no rocks in the tines or obstructions that I can see. The large pulley wheel on the top of the tiller will not turn. It seems like there is something inside where the chains are located that are preventing the gears from turning. Has anyone else ran into this? Should I try to take the tiller apart or would that not be advised?

If it won't turn for no apparent reason, it will have to come apart.

Let me find a thread on the disassembly

Thanks for the quick reply! Is it worth trying to get running again? Does not seem to complicated inside the tiller...

If it were mine, I'd fix it. They work quite well. After you go thru it and repair what's needed, it should be good for a few more decades of use.

Definitely take it apart and repair it!

The toughest thing when I took mine apart to replace a sheared pin was that one side of the tines was grown onto the shaft that it was pinned to. Once that was free, it was just a matter of disassembly, lube it thoroughly, then put it back together. I had ordered new bearings, thinking that the originals had to be worn, but they were fine. Replaced them anyway because I had them. If you need the tiller, order the bearings just in case. If you don't need them, return them.

Take lots of pictures for reference during the project.

i started to take some bolts off to get a feel of how hard they would be to get off. For those of you who have taken your tiller apart, how did you get the pulley off? I tried to loosen the Allen wrench nuts but it did not loosen the wheel?

Take the Allen head SET screw out and check if there is another in the pulley hub, if so remove it also.
Then squirt penetrating oil in the holes and let it set a bit and do it again.
Then install you 3 jaw puller, and pull it off using the bottom of the spokes @ the hub not out @ the belt area of the pulley or you will break it.:beerchug:

The pulley is keyed to the shaft. You will probably need to use a three jaw puller to remove it, also spray well with PB Blaster to help remove rust. Do not try to use a hammer to remove it as it is cast iron and is brittle. You can buy a cheap puller at Harbor Freight or try your local farm store. Also some auto parts stores will rent a puller.
Just review the thread in the link that Jeff sent and the parts breakdfown and you should be able to figurer it out. Remember that PB Blaster is your friend in this project.
Good luck, Later

On the pulley hub there looks like there might be a pin? If you have ever removed an axle from a car, there is a pin that bends over the axle and the rotor. Is there something like that on this pulley and hub?

One step @ a time, get the pulley removed from the shaft first, then we will walk you through removing the eccentric locking collar behind it, so the flange bearing can be removed,but you are thinking and that is good:beerchug:
