Cub cadet LTX1040

[Bill30733]

I have A cadet ltx1040. Other day I was Mowing and the blade belt came off. I put It back on and went about my business. I was Almost finished when it stopped pulling forward or reverse. I looked Under the battery and the (I’m assuming) is a transmission pulley(?) had come loose. I pulled It off and filed all the burrs off the mounting hole, reinstalled it and the bigger pulley was up against the small pulley. I looked Around and the second picture is what it’s supposed to look like and first one is what mine looks like. Now I didnt See anything bent and nothing looks out of place but I am New to cub cadets so I am Lost. Any help would be greatly appreciated and if you have questions please ask.

Thanks,
Bill

The first pic didn’t post so here it is. This is mine. Notice the differ between the pulleys

 

[T.R.K.]

The mount bracket for (What I call) the 'variable speed pulley' is suppposed to have two bolts in the left frame rail. As far as I know, those bolts have gone mssing and the mount slid over. These have 13mm heads, I think the only metric bolts on the whole chassis.

Or the bolts worked out of the bearing assembly that is bolted to the mount.

Or there are no longer any balls in the bearings that support the variable speed pulley.

Or the big transmission pulley is not centered on the transmision input shaft. If it is not on the shaft adapter splines it can be about 1/4" off center.

My other thought: Is the transmission still firmly bolted to the frame?

Isn’t one of those on a pivot? That machine has a 2 row sheave that has a movable center and that’s how it changes ratios for the variable speed feature. The pedal is connected to an idler which changes tension of the longer drive belt, and that causes the movable center section to slide and make one side of the sheave larger than the other and vary the input speed to the transaxle.
It would have to be on a spring tensioned pivot to maintain the belt tension. Is the spring connected? I just had one of those exact machines given to me by a neighbor. It also had a drive issue but I haven’t had any time to do anything but look it over a little.

Ok I will Have to check the 13 mm mounting bolts but I will Say everything that should be right is. The pulley is centered. That’s the pulley that came loose. I took It off and lightly filed the burrs and made sure the notches on the pulley were clean. Thanks

The spring is connected. And thanks. Also good luck with your issues.
