Free rolling jack needs parts

[aggie113]

Recently purchased a four post lift and it came with the shell of a rolling jack. Model QRJ04H to be exact. It has the internal lifting cylinder and all the locking/release hardware but nothing to pump/release the cylinder included. I was wanting to go with the air setup and an off brand solution was suggested to me. I'm not familiar at all with rebuilding hydraulic tools and wanted some opinions to see if the part might do the trick or anything else that might be needed to get the rolling jack working again.

Yes, you adapt a pneumatic-over-hydraulic pump over to a bridge jack quite readily. Judging by the fitting on the end of your hose, it probably had one of the Porta-Power type units on it: https://www.toolots.com/10000psi-po...Nf77MhYZhHvdE0-ijkWGXRW_w1h52JvhoChe4QAvD_BwE

I have a slightly used air/hydraulic pump that originally came from a bridge jack. We took it out of a new scissors lift at a Bear Training Center because the hydraulic tank dripped a little. A few minutes with sandpaper on the tank flange would have fixed it, but it was under warranty. It's dirty from being in storage. Can't remember if the lever on the pump is a manual release or the control. Let me know it this will work for you. I'll include a control valve, if you need it. This style pump was common in the 80's. They were also used to tilt the cabs on COE semi truck tractors.
