Does anyone know the size of the vacuum pump shaft and the taper on it? also the keyway?

LanceD

no one has a vacuum pump pulled who can measure for me?

LanceD

anyone?

LanceD, I think my buddy has one sitting around at the shop. I'll see if can get some measurements for you this week.

LanceD

woohoo! thanks!

If you can wait till the weekend, I have one sitting on my shelf at home that I can take a look at. I'm 800km from there at the moment, though.

LanceD

sounds good, I have been waiting for months already haha

Mike D

Sorry LanceD. I dropped the ball on getting the measurements for you. We've been pretty busy getting a truck ready for Pinks All Out this weekend. Just wanted to let you know I haven't forgotten.

LanceD

no prob, thanks for the update

Mike D

.619 on the shaft diameter. Didn't have a gear puller handy so don't have any other measurements at this time.

LanceD

Dang, I can't figure out which one it is. Im trying to replace my vac/ps pump with a dedicated high flow hydro pump to run a bunch of stuff. here are my options for shafts. which one do you think it would be?

Sir I have wondered if the case back hoe or lull with the 4 cylinder cummins could have a oil pump that you wont. There may not be enough room in the dodge frame. The 780 case backhoe had oil pump on the end of the crank I think. It had 24 volt starter and a air pump to be used on the air brakes. Manual tack. good luck

LanceD

I thought about running one off the front of the crank but there just isn't enough room up there for a pump.

Im going to run one thats 15GPM and a priority valve for the steering. the rest is going for a winch, on board air, and an on board welder. all hydraulic driven

Contact Pete Gould at fixinrams.com. Pete is a major source of remanned vacuum pumps. A hydraulic pump without a large reserve tank and a recirculation circuit will burn itself up before driving 50 miles. There is a belt driven hydraulic pump available from Northern tool that can be turned on and off with an electric clutch like an a/c clutch; flip a switch for hydraulic service, flip a switch to turn it off. Just a suggestion.

I know, I plan on running a 10-15 gallon resivoir. basically a full blown hydraulic system.
