The Stovebolt Site Forums The Parking Lot Big Bolts Hydrovac Help!

Hey gents. I've a '53 2.5Ton flatbed truck. I have the original unit but have found it impossible to find a rebuild kit. I've seen posts dating back to '07-'10 of rebuilds but nothing since. Are kits available or where should I go to purchase a rebuilt unit? I've found NAPA & Advance Auto have a hydrovac for up to a 3900 & base models. Best I can research, my 2.5 ton is in the 6000 series. Are they inter-changeable? Thank you for your help fellas.

I saved this from another post a while ago, you might give them a shout out.

"DS in VA has done a very good job for me, 276-322-3119, Jeff is the hydrovac gentleman, very knowledgeable, reasonable prices, unlike some others."

If you have a Series III vac then rebuild kits are all over.

Series II are the ones that are impossible to find.

If you have a 6000 Series truck than it's a 2-ton (4000 Series is 1.5-ton)...the 2.5-ton trucks didn't come out until 1956...

White Post Restoration in Virginia may do them, I know they do wheel and master cylinder sleeving/rebuilds. Look them up and give them a call.

I got my kit from http://www.cadillacpartsltd.com/ awesome service, about 200$ for the kit

O'Reilly Auto Parts might be able to get your core rebuilt for under $300

Thank you fella's. I reached out to the guys referenced by 69Cuda. I am trying to find where I left my ID tag to give them or send photo's with measurements to retrofit that way. They seemed confident they would be able to rebuild what I have and friendly. Once I get the tag/measurements, I'll be able to get a cost of the rebuild.

Thank you 69Cuda. I found my ID tag (374000) and they will rebuild my original core. $205 and then shipping both ways from/to KY. Thank you for the referral.

Thanks for posting the info, Snellen

That a very good price. I have a spare for my 54/55 350 GMC and will probably send it in now for a rebuild. Better safe than sorry.

Hi all,
Surprising. My Napa was able to source my Hydrovac. They did not sell the rebuild kit, but they took mine and sent it off to be rebuilt someplace ion KC. My Napa store, they even mentioned mine they had never seen before, but had sent others of "the larger size" off. My truck is a '48 2-ton 6400 series, and that conversation was yesterday.

I bought a rebuilt unit from Reman,Inc. If you don't know what you have/need, just give him the fitting sizes. I don't remember the cost, and there is a core charge. It was cheaper for me, to pay the core charge, than ship the core back. Very professional, great service! Good luck!
