1983 GMC Astro cabover restore and semi work

No but if you have it out you should be able to match it up at a hydraulic shop. We quite messing with them years ago and just bought new or rebuilt ones. Don't know if you can find one for an Astro anymore but one for an IHC would work.

 

Where is it leaking.

 

You will need to find a air powered pump off a KW or Pete. so you just push the button to help jack your cab up to show off your motor?

 

One company I worked at had an 86 White/GMC CO that had the air jack system.

 

Yes the air jacks are great. You can use either hand pump or air pump. Trash trucks have them. Want to say victors hyd sells all types.

 

Hey brother check out Ohiohydraulics.com. Division of power packer. Gives you the complete break down for cab lifting hydraulic system. I rebuilt mine on my 362 in on a few hours. Most time was spent cleaning the parts. Most oring are thin ones. Local part store should carry. Ounce you get pump rebuilt. Vent lifts cyclinders down then vent up. Then refill tank.

 

Then jack cab up until off pads. Then select natural. Check for leaks. You will hear some noise as the cab lifts. Watch for gear shift and cab separation. Not sure how yours is. Thinking the gear shift is mounted on a bracket.
