Case 1816B Uprade Hydraulic Equipment Pump

LittleMontana · Dec 27, 2019

Hey everyone, I have a Case 1816B that I have been toying with for a couple of years. To date I have cleaned it up a bit, replaced both drive motors, and next week I am repowering it with a new Honda GX630. I am thinking about adding a quick attach front end to give me a little more versatility. One thing I would like to be able to run is an auger. I have found a few and the one I am currently looking at runs between 10 and 20 GPM. So far I have not decided if I will put in a true auxiliary circuit or if I will use a diverter circuit off of my tilt controls. The questions come about the current 8GPM equipment pump. I think I should be able to upgrade the pump, I found a chief gear pump with a range from 9.5 to 19.1 GPM. Am I looking at destroying the rest of my equipment hydraulic circuit by over loading it? Are there other items I am over looking? Any suggestion will be greatly appreciated. Sorry if this is a stupid question but I am not overly familiar with hydraulic systems yet... Getting better though

Thanks much.

Your biggest issue will be the HP to drive the pump. You say it has an 8 now, you are hoping to replace the motor, you will need to go bigger if you hope to use it to run more GPM.
The next issue is the hoses, if they are too small, they will heat up faster due to being undersized.
Honestly, I'd want to stay the same or if it was worn out, go say 2 gmp larger, but not doubling it, or even higher.

Thanks for the information, maybe an auger is asking too much for Christmas.

Thank you, LittleMontana

An auger shouldn't require that much flow, my 700 came from a fence company that used an auger on it and it only has about 7gpm aux flow. I think it was a Lowe auger, it was one of the box type with a chain drive, not one of the planetary fit-down-the-hole newer drives.

Cool, I will look into that. It makes sense, the one I was looking at was one of the planetary types. Thanks for the info. LM
