The plastic roller for the spring rod of the rear trunk lid hinge looks like it’s about to come off of the shaft. What techniques do folks use for releasing the tension of the spring? Is it then just a matter of pushing the roller further onto the shaft and putting the spring back in place?

Thanks,
Mike

Not sure about pushing it back on. I will tell you those spring rods hold a ton of tension and several people have hurt themselves trying to release them w/o knowing how. Before you touch that, please read some threads on it. Many have posted how they do it so they do not injure themselves or damage the car. (IMG:style_emoticons/default/beerchug.gif)

I recently replaced my rollers with new ones. Someone suggested to use water pump pliers to push down the torsion bar (spring). that didn't work for me. I took a 30" long iron pipe with 1" OD and 3/4" ID and cut a slot into it about 1/2" from one end just wide enough to fit around the spring. I was able to push down on the spring, slide off the old and put on the new. Still a very dangerous undertaking. Be careful...

Might just be the camera or the center of the roller is worn out, but the post looks bent.
At any rate I'd find a how to thread and replace the roller.

Go to the other end of that torsion bar and tap it across the car to move the wheel
further onto the shaft.
You may have to work it on from one side then the other.
Also, with the hood off the hinge moves outward.

I’d check to make sure your hinge pivot mount is in good shape.

Looks like the base hinge is separated from the wall.

Thanks for the replies. I’m still looking for a good and safe way to relieve the tension on the spring so I can assess the situation and make any necessary repairs. I did a forum search but didn’t see a valid post. I heard at one point there was a tool available. Anyone know of one and a source?

Thanks,
Mike

Hey Mike, I got my torsion tool from AA. It was invaluable to put my springs off and on.

I cringe every time one of these trunk torsion bar threads pops up. I keep waiting for someone to lose a finger...or worse. I'm a damned lucky example (it was close).

I second that it looks way out of place and the inner fender pivot point may be torn. Look underneath and ensure both of these are solidly mounted to the sides; it's very common for them to be torn:

I saved the image of how to construct a tool from a 1" x 12" strip of 1/4" plate steel. The North Coast Jim special. (IMG:style_emoticons/default/biggrin.gif)

I've always dreaded the thought of having to put the torsion bars back in place on my project when the time comes, and this seems like a good plan.

Forget the torsion bars, save your fingers, hinge plate, and sanity and go with the cheap & safe trunk shock kit.

-1 on the rear struts, I won't put those on any 914.

Fix the hinge cup and keep the shoulder bolt lubricated, or do the shoulder bolt mod. It's worked for 40+ years, and needs repair. Yes, there's a dangerous amount of tension on those springs, but if you get a good tool it's not that troublesome.

Something looks off, hard tell what from the photo. I use a crescent wrench and socket to take the load off. http://www.914world.com/bbs2/index.php?showtopic=39320

This has worked for me. Be very careful and get someone mechanically inclined to help.

When the lid is not on the car that arm wants to push outward which makes the pin where the roller rides tilt up slightly. When you push inward and have the lid bolted on does it go to the correct orientation?

I do not believe it is a hate. I just believe there may be a preference for keeping the original pivot and plastic roller in place. I would fix it correctly with the stock parts and likely never have to deal with it again.

I just see the struts as an unnecessary modification for the sake of a modification. Believe me, I have made a few mods on my car, so I am not a "purist" but I believe the original design worked well and really only fail when not properly maintained.

Now if you have a car that is far from stock and the trunk rods were removed in the pursuit of space savings, then use the struts and never look back. (IMG:style_emoticons/default/beerchug.gif)
