I acquired an 1811 last year and I have had an issue with vibration in the driveshaft for the hydraulic pump. I replaced the joints, did ok for a while. Then the vibration got real bad. I pulled the transaxle and dug into it. Transaxle got pulled for shearing frame to trans bolts, getting an upgrade.

Once I got everything apart found the brass bushing to be bad, coupling arm is toast and the pin holes on the charge pump shaft are egged out. That shaft is really expensive, do I replace or weld up the holes and re-drill?

I would replace it with a good used shaft. If it is welded up and redrilled, it will probably wear faster than it originally did since the heat treatment will be damaged.

Replace both input shaft needle bearings while you are in there, too.

I'd have to replace it with a used one. New, the shaft runs $729 from Cub Cadet.

Anyone got a good used charge pump shaft?

Without a picture I am not sure about which shaft you need. If it is the shaft that drives the hydro pump I have one that fits a 682 tractor. Don't know if they are the same.

He is talking about the hydro unit input shaft. Any CC hydro model without a splined input shaft should fit.
