This is a rebuilt Vickers TA1919 variable displacement tandem hydrostatic drive pump. This pump has been rebuilt to new factory specs, then bench tested to ensure it is working properly before it is shipped.

You must clean out the drive motors and hoses and replace the hydraulic oil and filter when installing this pump. When a drive pump fails, some of the metal shavings can be washed into the drive motor. If this pump is replaced without having the contamination removed from the system, you can end up with the same problem you were trying to fix. Damage caused by contamination from your system is not covered in our warranty.

This pump is an assembly that consists of the right and left side drive pumps and the vane pump on the front that supplies the hydraulic circuit that does the lifting and dumping. It is used in many Bobcat skid steer loaders including models 630, 631, 632, 641, 642, 642B, 643, 730, 731, 732, 741, 742, 742B, 743, and 743B.

This pump replaces many bobcat part numbers including 6648980, 6558724, 6648981, 6630101, 6630535, 6560208, and 6630534. The reason for all the different part numbers is a minor design change, different numbers for new and rebuilt pumps, and different charge pressure springs for older machines.

This pump is used in all these machines, If there is no serial number information listed, then all pumps used on your machine update to this pump.
