The Stovebolt Site Forums The Parking Lot Big Bolts Bendix hydrovac on Ebay.

Howdy all. Thought I would mention for folks working on "Big Bolt" brakes that there is a rebuilt Hydrovac listed on Ebay for $150 plus shipping. It's a "Buy if Now" price, so no bid is needed. You can just buy it.

I needed one for my 59 Viking (turns out it needed brake work two owners ago..they told me they just used the hand brake to stop it!) After comparing photos and researching part numbers, I bought one of these from the fellow..he lists it as a replacement for White and Studebaker trucks. Turned out it's also a direct replacement for the 59 Chevy Viking as well. I recieved the one I bought from him very quickly, two days if I remember right. I live in New Mexico, only one state away from the seller. After researching rebuild kits and rebuilt units from Napa and others, I figured $150 for one already rebuilt was a pretty good deal, and no core charge. He only has one left. Someone might be able to use it.

do you know if it would work on a 53 351 gmc coe? they seem to look the same.

I've got one thats in good shape you can have for $100.00 I am completely turning mine into a car hauler and using disc brakes so I dont need the hydravac unit

Mines off a 47 COE

Psac,

The GMC Master Parts Books indicates that the part number of the hydrovac unit on eBay (ID model 374980, part number 2241895) is for a 370 FCS GMC.

Hydrovac ID model 374000 (part number 2208488) was used on 350 series GMCs (up to at least 1953). This most likely does not mean that the eBay unit will not work; it might work fine by swapping some of the attachment fittings.

If I am incorrect, let's hope that someone corrects this.

Roy, GMC or Chevrolet COE - what size, if GMC? Is there a part # or ID on a tag or on the hydrovac's body?

It's a 1947 Chevy COE I know its a Bendix and I would have to go look to see if there is a number. If you are real interested let me know and I will go look at it and take some pics for you. Merry Christmas Roy

I bought hydrovacs on eBay for a couple of my old GMC's that were for some odd ball truck. They work because there's not that much difference in Bendix. In the 50's it was quite common to go out and buy a hydrovac and make it work.

I have just got the truck home this past week and with the storm I just got it cleared today. If the now rain stays away. I can get some work done.

I don't know anything about numbers ETC. until I can remove the unit.

Thanks for the parts numbers. It will come in handy. I need to make shure that the correct unit or a proven replacement is installed.

Just a short reminder, fellers.

If you have something to sell or trade, please listit in the SWAPS forum.

Please dont put anything in Big Bolts or elsewhere for selling or buying things.

John will jump right out of his Santa Claus suit and start throwing lumps of coal at all of us.

Glenn, You need to read the whole thred. You are jumping the gun here. One guy just let me know he has one if I need it. He could have put it in an email to me.

roy, Please contact me at my regular company email at [email protected] and send me some pics of the unit you have.

Is this off a running truck? and are you looking to get rid of the other parts that are in the system?

If it is a running truck.... well. I may want it all.

Mine has not been on the road for a few years... 1996.

thanks
