sunstrand pumps and motors

[Doug Hanson]

Here is an example of a regen bench, just a basic drawing.

Thanks so much for all your info and if you run across any schematic for my test stand please send me any info on that and anything on a four rod mount system. I really would like it to work well for me and not waste allot of money. I am almost finished building my cummins diesel 855 for my main drive.

I see you have information to help decipher model codes. I Have a mst 1100 morooka(komatsu) with Daikin/sundstrand hst system. The motors in this unit are BM22-14ctbf-50. Apparently more common motors for this application are BM22-24CTBF-55. I am told that the numbers 14 and 24 indicate reduction ratio in the final drive but am not clear which is higher or lower or how to determine how much.

Would greatly appreciate it if anyone can shed some light on this mystery for me.

Sorry Ian, I have looked through all of my books and have no information on those units, hopefully someone else following has some information?

Had to fix up an error on the regen test bench schematic posted earlier.

TEST MESSAGE

[allprohydr]

I got your words test message. Do you have info to share?

[Doug Hanson]

Nope, just trying to sort out some technical difficulties. Well... I did just pick up a twelve valve cummins 5.9 litre for my latest test bench project (the regen one). That's about it. Interested in swapping a 27 series fixed displacement motor for anything? I could use a fixed displacement, or variable 24 series motor.
