How to properly service the Hydrostatic Drive???
 

I am sure this has been covered 1000 times but I couldn't find anything when searching the forums. What is the proper way to service the Hydrostatic drive on my 782. I bought the fluid and the filter from the Cub dealer yesterday but I am not exactly sure where to empty it and where to fill it and if it is possible to over fill it? I would rather look like a Dumb A%$ than mess it up so I had to ask. Thanks ahead of time.

IF your 782 has a Chassis Serial Number of <719,999 then Click on this link as found in our Technical Library Section....Manual #1......

IF your 782 has a Chassis Serial Number of 720,000> then click on this link..... Manual #2

I found in the link how to disassemble the hydro unit but I just want to change the fluid in it.

You need to remove the rear plate to drain the fluid. While you are in there, be sure to clean out all the sludge with some brake/carb cleaner. You will need to make another trip to the deal and get a gasket for the rear cover. You fill it to the bottom of the plug in the rear cover.

Gaskets for a farmall cub rear end(same thing as in a cub cadet) are about $7.00. Be sure to get all of the old gaskets off both surfaces, abd I always use a bit of form-a-gasket on both sides too

If your 782 is CCC built and has an Aluminum Rear End, then the fill is via a "dipstick tube" underneath the seat.
