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

 

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

 

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.

 

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.

 

sounds good, I have been waiting for months already haha

 

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.

 

no prob, thanks for the update

 

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

 

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

 

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.
