Concensus on rebuilding PS control valve on 1772
My power steering control valve is starting to leak pretty bad. The last new one I bought was about 10 yrs. ago, and was almost 600.00. They are more than that now. There are sellers on Ebay selling a rebuild kit for it. I have heard over the years, that these things aren't rebuild able, but yet you can buy the kit to do it so. Is there anyone out there that has successfully rebuilt one, or is it not worth the effort? If you do rebuild it, and wind up with one that is a little less leaky than when you started? This is the same valve on just about all the Supers from 1572, 1872, 2072,etc.
Thanks in advance |

For the record, I have NOT attempted this. My son has a 2072 with Power Steering and is running into the same leaking issue(s).
I have read several posts about rebuilding these units, with a "repair kit", and if I recall, they had success. It is a time consuming, and tedious project. It seems these guys, took their time, being patient, and went through it. If you are going to attempt this, make a log of how things came apart, and take lots of reference pictures

I've rebuilt many power steering units and went through quite a few customer's that tried to reseal themselves without paying attention to detail.
It's easy enough to do, but different manufacturers have different designs for some internals. Some have tiny check balls in the rotor disc, others have a check ball under a special bolt (that looks like the rest of the bolts holding it together) that doesn't get noticed. Most have some small coil springs, and have a set of opposing leaf springs for "return to center". If you can identify your particular unit (they are used on many machines) find a clear parts breakdown and watch a few GOOD youtube videos. At work, it was a one hour job, including cleaning and a quick massage for all surfaces on a flat plate. It's a job well within the scope of most guys that enjoy tinkering with tools and machines. Devils in the details. |

Here is probably one of the best links I have seen. Don't pay attention to the shaft being shorter. That's a common problem with deere guys.

I'd just check if the kit is cheaper on-line, from a hydraulic shop or the JD dealer. It's a Ross, so should be easy to get.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
