743B hydraulic pump and 642B pump

[racingjoe66]

Will a hydraulic pump from a 743B Bobcat fit onto a 642B? Or any of the drive trail and hydraulic stuff? I have the ability to buy a cheap 743B a guy has locally and thought if any of the parts would work on mine or the higher flowing pump would be nice. Thanks

I was able to find out the pump will work. Will there be any issues with changing out my 10.8 gpm pump on my 642B with a 12.1 gpm pump from a 743B? Thanks

Honestly, i can't tell you for sure. The extra flow will need to go through the oil cooler, i'm not sure if it's the same size as a 7 series or not. I'd like to think it would work just fine, the hydraulics will move a bit faster.
The only issue i can see is that with the extra flow, you will need more HP to power it, so your engine may not be up to the task of giving full lift/tilt speed and power without bogging down.
Worst case, you can swap out the vane pump later if needed, but it's worth a go.
