Title: 1955 hood springs
Post by: walt c on May 30, 2018, 09:05:50 AM
Hi guys!
  I have owned and driven my 1955CDV for 19yrs and after assembling it (I received it as a basket case)ran into a hood that wouldn't stay up. After trying all three lower spring adjustment positions and failing, I did a  reliable fix by installing a hold open rod from a local junk yard. Time marches on and I finally  decided to finally change the springs out with some USA made ones. Still NG! Has anyone else ran into "hood not staying up" and what was your fix? ....??troubled in Tulsa??.....walt

Hi Walt, I must admit that my good seems a bit low when it's open. I used to think that this was normal but from reading posts over the last few years I think that it wasn't like that from the factory. Btw I had the hinges re rivetted etc but that doesnt affect the height when open. Phil

Hi Walt, I've had the same problems with my springs over the years.

I bought these on eBay and kept my fingers crossed that they would do the job.........I always wonder that "new" means built from inferior quality materials or not the correct tension.

But these kept the hood up and so I bought another set for an Eldorado I have.

As you know, this is one scary job to do so please be careful!

I've restored several 55-56 cars and one thing to know is that there's more than one position for the hood spring to attach at its lower end and it can make quite a difference.  I rigged up a tool similar to the one that they used in 41.  Lubrication can also make quite a difference.

Hello Ken ,
              Where are you applying the lubrication?
Thanks,
 
Bob

Guys,
  I "rebuilt" my hinges years ago using oil lite bronze bushing. I continue to lube the hinge points with "breakfree" gun lube occasionally. (easy to apply with it's long application tube) If anything, the hood hinges work as if their on bearings! I bought the same springs as Mike and have the lower attach point on the middle setting. As far as working with springs, well, they scare me! Even with the "special" installation tool I made, it's WORK.
  See no other option (unless I try the other two lower attach points which I probably will eventually) other then continuing as I have for years using the "hold open" rod......thanks everyone and PLEASE be careful when working with springs.....walt...tulsa,ok....ps. the upper attach point picture in the manual shows the spring hook "open" on it's aft side.....you don't suppose the opening should be towards the front? (if so,this would be the first time I put something together backwards,ever......)

I have purchased the same springs from that vender. The diameter of the new springs is smaller then the original. My hood opens the same as with my original springs. As for the 3 adjustments on the bottom of the spring, that is to position the hood forward or toward the cowl. It does not adjust the spring tension. It says so in the shop manual.  I'm thinking of welding the bottom coils together on the springs to get more tension. That way you still have the correct shape. I don't know when I will have time to get to it though.
I believe that someone had cut out 1 coil on the spring and it worked great, but never mentioned how they bent the spring to get the correct shape.

I must have got lucky with my eBay springs.......their doing alot better than the old ones.

George someday when you get to trying that welding the bottom coils together please post how that worked out.

Walt also if you try the open end of the hook facing forward please post how that worked out also.

Walt, as far as your "special" installation tool......I bet yours is better than mine......I used a 4 foot bar, a "S" hook......and an old fan belt....yikes !   I hope I never have to use that setup again!

For installationof those hood springs, this is what I have done: Strech the spring apart with an engine hoist and fill the spaces between the coils with wrenches. Install the spring and start pulling out wrenches. Easy :)

I've heard about this way of installing the springs using large washers put in between the coils.

With the hood closed I didn't think I could get my arm up inside the fender to remove the washers....

I'm not sure if this tip can be made to work on the '55 springs type, just in case if there is a modification on this hint that can be done to work on the '55.  ;)
