Vickers TA1919 drive pump for bobcat with $1100 core
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 12 month warranty.
This pump is an assembly that consists of the right and left side drive pumps and the vane pump on the front 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, 643, 730, 731, 732, 741, 742, 742B before serial number ****18000, 743, and 743B before serial number ****18000.
This pump replaces many bobcat part numbers including 6558724, 6648981, 6630101, 6630535, 6560208, 6648980, 6630534, and 6660948. The reason for all the different part numbers is a minor design change, different numbers for new and rebuilt pumps, and different charge pressure settings for older machines.
The charge pressure spring is the only item that is important. There are several ways to identify the correct pump for your machine, your machine serial number, the charge pressure spring length, or the number stamped into the aluminum housing close to where it bolts to the center port block section.
