Today Im going to be rebuilding my drive motor on my Bobcat 743B, the 743 should be identical. I recently rebuilt my left drive motor which is essentially identical to this DIY just a mirrored version of the right pump. Loader parts source which I am not affiliated in any way with has the best bang for the buck kit on the market the factory bobcat kit is insanely expensive and obviously not really worth it with this one coming in so cheap.

Tools Required:
1. Breaker bar 1/2"
2. SAE standard Allen/Hex sockets
3. SAE socket set
4. 1/2" to 3/8" socket reducer
5. Various 1/2" extensions
6. Impact gun however not necessary will make your job easier
7. Heat source, I used a acetylene torch a map torch will be just as effective
8. A workbench or a vice secured so you can break pump bolts loose
9. Two large adjustable crescent wrenches
10. Some Dielectric grease as this type of grease will not swell the orings and provides enough lubrication.
